I'm trying to get the text from a input textfield and place the value in a table row, but each time someone posts something the oldest post moves down 1 row, here's what I have but I'm very confused now
<HTML>
<HEAD>
<SCRIPT Language="JavaScript">
<!--//
function thisPost(frm){
if (frm.postHere.value == "")
alert("Hey! You didn't enter anything!")
else
frm.postHere.value = ""
<table style="width:100%">
<tr>
<td>post + frm.postHere.value</th>
</tr>
</table>
}
//-->
</SCRIPT>
</HEAD>
<BODY>
<FORM NAME="thisPost">
<P>Post this: <INPUT TYPE="TEXT" NAME="postHere"><BR><BR>
<INPUT TYPE="Button" Value="Post" onClick="thisPost(this.form)">
</P>
</FORM>
</BODY>
</HTML>
Demo on Fiddle
HTML:
<label>Post this:</label>
<input type="text" name="postHere" />
<br />
<br />
<button>Post</button>
<table></table>
JavaScript:
var btn = document.getElementsByTagName("button")[0];
var inpt = document.getElementsByName("postHere")[0];
var cnt = 0;
btn.onclick = function() {
if (!inpt.value) alert("Hey! You didn't enter anything!");
else alert("The field contains the text: " + inpt.value);
var tbl = document.getElementsByTagName("table")[0];
var row = tbl.insertRow(cnt++);
var cell = row.insertCell(0);
var txt = document.createTextNode(inpt.value);
cell.appendChild(txt);
};
There's a number of syntax errors in your code, so I'm not sure how you are able to run it in its current state. Also, your markup and approach is fairly dated. I would highly recommend investing time in a cross-browser DOM framework like jQuery and then an good front-end MVW and templating framework. That aside, I've re-worked your code into a more usable form. Hopefully this will get you going.
function thisPost(){
//Use getElementById to retrieve the DOM elements you're looking for
var txtPost = document.getElementById('txtPost');
var post = txtPost.value;
if (post == "") {
alert("Hey! You didn't enter anything!")
} else {
alert("The field contains the text: " + post);
//Get a reference to your table
var table = document.getElementById('posts');
//TODO: This is unsafe and subject to script injection.
//http://en.wikipedia.org/wiki/Code_injection#HTML_Script_Injection
table.innerHTML = '<tr><td>' + post + '</td></tr>' + table.innerHTML;
txtPost.value = "";
}
}
//from: http://stackoverflow.com/a/10150042/402706
// add event cross browser
function addEvent(elem, event, fn) {
if (elem.addEventListener) {
elem.addEventListener(event, fn, false);
} else {
elem.attachEvent("on" + event, function() {
// set the this pointer same as addEventListener when fn is called
return(fn.call(elem, window.event));
});
}
}
//Don't bind events in your HTML markup, instead bind them in JavaScript.
addEvent(document.getElementById('btnPost'), 'click', thisPost);
table{
width:100%;
}
<form name="thisPost">
<p>
Post this: <input type="Text" name="postHere" id='txtPost'>
<br/><br/>
<input type="Button" value="Post" id='btnPost'/>
</p>
<table id='posts'>
</table>
</form>

I have a small question,
I am yet a beginner with Java Script and I don't have that much of knowledge with it. My question is:
I need to create a fake donation form. The form contains fields where the user can write his data like his phone number, donate amount etc... and when the user hit submit his donate amount and his name should be shown in a table, besides the last other 4 donations of the other people. I think that my code should look like that
<body>
<div id="container">
<form action="#" name="myForm" id="myForm">
<br>name: <input type="text" name="name" id="donatorName"></br>
<span id="Enter your name"></span>
<br>Donate amount: <input type="number" name="donateAmount" id="amount"></br>
<span id="Your total donate amount"></span>
<br/>
<button type="button" value="submit" onclick="return validation(); document.getElementById('container').style.display='none'">submit</button>
</form>
</div>
<div id="new_container">
<p id="displa_name"></p>
<p id="display_total_amount"></p>
<div id="Btn"></div>
</div>
<script type="text/javascript">
function validation(){
var donatorName = document.getElementById("donatorName").value;
var donateAmount = document.getElementById("amount").value;
// donatorName validation
if(donatorName == ""){
document.getElementById("donatorName").innerHTML = "Name cannot be empty";
document.getElementById("donatorName").style.color = "#ff0000";
return false;
}
// donateAmount validation
if(donateAmount == ""){
document.getElementById("amount").innerHTML = "Total amount cannot be empty";
document.getElementById("amount").style.color = "#ff0000";
return false;
}
if(donateAmount < 1){
document.getElementById("amount").innerHTML = "Donate amount should be greater than 0";
document.getElementById("amount").style.color = "#ff0000";
return false;
}
showDetails();
}
function showDetails(){
document.getElementById('container').style.display='none';
// name
const = document.getElementById("amount").value;
document.getElementById("display_name").innerHTML = `DonatorName: ${donatorName}`;
document.getElementById("display_total_amount").innerHTML = `TotalAmount: ${donateAmount}`;
</script>
</body>
I am not sure about my code, so please help me and explain to me how else I can do it. I want to keep it simple for now so please give me some advices :D
I recommend you use backend language for this, like PHP, but if javaScript is what you needed, here's a simple way for that.
You can store the data in an array, or cache them so that the data will not be lost even when tab is refreshed.
But let's use array for this example. You already have your form so let's skip it.
For the table in HTML:
<table>
<thead>
<th>Name</th>
<th>Amount</th>
</thead>
<tbody id="displayDonations">
<!-- Data will be displayed here thru javaScript -->
</tbody>
</table>
javaScript:
let donations = [];
function validation() { // This is called when you submit the form
// Put your validations here
// Example Validation: return false if not valid
if (!isValid()) return false;
// Remove first element of the array if length == 5
if (donations.length == 5) {
donations.shift();
}
// Push object into the donations array
donations.push(
{
"name" : document.getElementById("donatorName").value,
"amount" : document.getElementById("amount").value
}
);
showDetails();
}
function showDetails() {
let tableBody = "";
donations.forEach((element) =>{
// Construct what you want to display
tableBody += ""
+ "<tr>"
+ "<td>" + element.name + "</td>"
+ "<td>" + element.amount + "</td>"
+ "</tr>"
;
});
// Write the tableBody to the HTML
document.getElementById("displayDonations").innerHTML = tableBody;
}
I have looked through a lot of the already asked questions and cannot find it. I need the previous appended message to be deleted once you hit the submit button again. So this will let you choose your character that you type into the input field and then it will append a message bellow telling you that you choose x character. After that you can resubmit another character which I want, but I do not want the previous append to be there.
I tried to do a search function in javascript and if it was not equal to -1 then delete the first p in the div, but that did not work=/
Thanks for your help in advance.

$(document).ready(function() {

};
redirect = function() {
var text = document.getElementById('text').value;
var url = text+".html";
window.location.href = url;
}
So your variable send gets sent and then it clears out the input field with either of those functions
$(document).ready(function() {
$('#button1').click(function(){
$('#box_holder').children('p').remove(); <===========
or Either of these should work
$('#box_holder').empty(); <===========================
var send = $("input[name=mess]").val();
$('#box_holder').append('<p>'+ 'You have chosen your character to be: '+send+'</p>');
});
$('input').css("color","blue");
});
Instead of using append, try using html as follows
$('#box_holder').html('<p>'+ 'You have chosen your character to be: '+send+'</p>');
Here is a Plunkr to explain it a little better
$(document).ready(function() {
$('#button1').click(function() {
var send = $("input[name=mess]").val();
$('#box_holder').html('<p>' + 'You have chosen your character to be: ' + send + '</p>');
});
$('input').css("color", "blue");
});
chooseChar = function() {
var text = document.getElementById('text').value;
text = text.toLowerCase();
if (text == 'human') {
$(document).ready(function() {

You have to remember, the append() function appends the content on the selected component. The html() function replaces all content inside of it.
Hope it helps
im very new at javascipt (im php developer) so im really confused trying to get this working.
In my web form i have 3 textfields (name, description and year) that i need to let the user add as many he needs, clicking on a web link, also, any new group of text fields need to have a new link on the side for removing it (remove me).
I tried some tutorial and some similar questions on stackoverflow but i dont get it well. If you can show me a code example just with this function i may understand the principle. Thanks for any help!
this is the simplest thing that has come to my mind, you can use it as a starting point:
HTML
<div class='container'>
Name<input type='text' name='name[]'>
Year<input type='text' name='year[]'>
Description<input type='text' name='description[]'>
</div>
<button id='add'>Add</button>
<button id='remove'>Remove</button>
jQuery
function checkRemove() {
if ($('div.container').length == 1) {
$('#remove').hide();
} else {
$('#remove').show();
}
};
$(document).ready(function() {
checkRemove()
$('#add').click(function() {
$('div.container:last').after($('div.container:first').clone());
checkRemove();
});
$('#remove').click(function() {
$('div.container:last').remove();
checkRemove();
});
});
fiddle here: http://jsfiddle.net/Fc3ET/
In this way you take advantage of the fact that in PHP you can post arrays: server side you just have to iterate on $_POST['name'] to access the various submissions
EDIT - the following code is a different twist: you have a remove button for each group:
$(document).ready(function() {
var removeButton = "<button id='remove'>Remove</button>";
$('#add').click(function() {
$('div.container:last').after($('div.container:first').clone());
$('div.container:last').append(removeButton);
});
$('#remove').live('click', function() {
$(this).closest('div.container').remove();
});
});
Fiddle http://jsfiddle.net/Fc3ET/2/
jsFidde using append and live
String.format = function() {
var s = arguments[0];
for (var i = 0; i < arguments.length - 1; i++) {
var reg = new RegExp("\\{" + i + "\\}", "gm");
s = s.replace(reg, arguments[i + 1]);
}
return s;
}
var html = "<div>" + '<input name="name{0}" type="text" />' + '<input name="description{1}" type="text" />' + '<input name="year{2}" type="text" />' + '<input type="button" value="remove" class="remove" />' + '</div>',
index = 0;
$(document).ready(function() {
$('.adder').click(function() {
addElements();
})
addElements();
$('.remove').live('click', function() {
$(this).parent().remove();
})
});
function addElements() {
$('#content').append(String.format(html, index, index, index));
index = index + 1;
}
Look at this: http://jsfiddle.net/MkCtV/8/ (updated)
The only thing to remember, though, is that all your cloned form fields will have the same names. However, you can split those up and iterate through them server-side.
JavaScript:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#addnew").click(function(e) {
$("#firstrow").clone() // copy the #firstrow
.removeAttr("id") // remove the duplicate ID
.append('<a class="remover" href="#">Remove</a>') // add a "remove" link
.insertAfter("#firstrow"); // add to the form
e.preventDefault();
});
$(".remover").live("click",function(e) {
// .live() acts on .removers that aren't created yet
$(this).parent().remove(); // remove the parent div
e.preventDefault();
});
});
</script>
HTML:
Add New Row
<form id="myform">
<div id="firstrow">
Name: <input type="text" name="name[]" size="5">
Year: <input type="text" name="year[]" size="4">
Description: <input type="text" name="desc[]" size="6">
</div>
<div>
<input type="submit">
</div>
</form>
Try enclosing them in a div element and then you can just remove the entire div.
Try this
Markup
<div class="inputFields">
..All the input fields here
</div>
Add
<div class="additionalFields">
</div>
JS
$("#add").click(function(){
var $clone = $(".inputFields").clone(true);
$clone.append($("<span>Remove</span").click(functio(){
$(this).closest(".inputFields").remove();
}));
$(".additionalFields").append($clone);
});

This question has been posted almost 4 years ago. I just provide the info in case someone needs it.
This is an assignment from my class. What I need to do is create a registration page. When the user presses the submit button, I have take all the information on the form and write it to an existing XML file using Javascript. This is done on the client side, only through HTML, Javascript, and XML. By the way, my Professor purposely did not teach us how to do this because he wants us to research on it by ourselves. Also, I'm not too familiar with Javascript, especially with the built in functions, if possible please explain what each line or method of code is doing.
Let me begin, here's how my existing XML looks like:
<?xml version ="1.0" encoding="utf-8" ?>
<!--GGFGFGFVBFVVVHVBV-->
<PersonInfo>
<Person Usrname="Bob111" Pswd="Smith111" personid="111" FirstName="Bob" LastName="Smith" DOB="01/01/1960" Gender="M" Title="Hello1">
</Person>
<!-- several more lines of <person> here -->
</PersonInfo>
When saving the form data, it has to follow all the layout within , basically I would need Usrname, Pswd, personid, and so on.
Basically, from what I understand, I have to create the XML line "Person" from my registration page once I press submit. Then push it to the array that already have my XML information, then write over my XML document with the information on the array. My problem is, I have exactly no idea how to do that.
For those who wants to know how my registration page looks like, here it is:
<html>
<head>
<title>Registration</title>
<link rel="stylesheet" type="text/css" href="CSS_LABs.css" />
</head>
<body>
<div class="form">
<form id="Registration" action="" method="get">
Username:<input type="text" name="usrname" maxlength="10"/> <br/>
Password:<input type="password" name="pswd" maxlength="20"/> <br/>
<hr>
PersonID:<input type="text" name="PID" /> <br>
<hr>
First Name:<input type="text" name="fname"/> <br>
Last Name:<input type="text" name="lname"/>
<hr>
DOB:<input type="text" name="dob" /> <br>
<hr>
Gender:<input type="text" name="sex" /> <br>
<hr>
Title:<input type="text" name="title" /> <br>
<hr>
Secret Question:<br>
<select name="secret?">
</select> <br>
Answer:<input type="text" name="answer" /> <br> <br>
<input type="submit" value="submit" />
</form>
</div>
</body>
</html>
By the way, I know certain information on my HTML document may not be worded properly, so do hope you guys don't mind. Also, I would also have to fix up my XML later by putting the answer to the secret question within later.
Alright, thanks a lot in advance guys.
UPDATE!!!
Here we go, I finally figured out how to create an XML document with Javascript, here's the code:
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
var fso = new ActiveXObject("Scripting.FileSystemObject");
var FILENAME = 'G:\\CST2309 - Web Programming 1\\Copy of Take Home Exam - Copy\\PersonXML2.xml';
function SaveXML(UserData)
{
var file = fso.CreateTextFile(FILENAME, true);
file.WriteLine('<?xml version="1.0" encoding="utf-8"?>\n');
file.WriteLine('<PersonInfo>\n');
for (countr = 0; countr < UserData.length; countr++) {
file.Write(' <Person ');
file.Write('Usrname="' + UserData[countr][0] + '" ');
file.Write('Pswd="' + UserData[countr][1] + '" ');
file.Write('PersonID="' + UserData[countr][2] + '" ');
file.Write('FirstName="' + UserData[countr][3] + '" ');
file.Write('LastName="' + UserData[countr][4] + '" ');
file.Write('Gender="' + UserData[countr][5] + '" ');
file.Write('DOB="' + UserData[countr][6] + '" ');
file.Write('Title="' + UserData[countr][7] + '"');
file.WriteLine('></Person>\n');
} // end for countr
file.WriteLine('</PersonInfo>\n');
file.Close();
} // end SaveXML function --------------------
function LoadXML(xmlFile)
{
xmlDoc.load(xmlFile);
return xmlDoc.documentElement;
} //end function LoadXML()
function initialize_array()
{
var person = new Array();
var noFile = true;
var xmlObj;
if (fso.FileExists(FILENAME))
{
xmlObj = LoadXML(FILENAME);
noFile = false;
} // if
else
{
xmlObj = LoadXML("PersonXML.xml");
//alert("local" + xmlObj);
} // end if
var usrCount = 0;
while (usrCount < xmlObj.childNodes.length)
{
var tmpUsrs = new Array(xmlObj.childNodes(usrCount).getAttribute("Usrname"),
xmlObj.childNodes(usrCount).getAttribute("Pswd"),
xmlObj.childNodes(usrCount).getAttribute("PersonID"),
xmlObj.childNodes(usrCount).getAttribute("FirstName"),
xmlObj.childNodes(usrCount).getAttribute("LastName"),
xmlObj.childNodes(usrCount).getAttribute("Gender"),
xmlObj.childNodes(usrCount).getAttribute("DOB"),
xmlObj.childNodes(usrCount).getAttribute("Title"));
person.push(tmpUsrs);
usrCount++;
} //end while
if (noFile == false)
fso.DeleteFile(FILENAME);
SaveXML(person);
} // end function initialize_array()
What this code here is doing is that, it takes my original XML file and loads it up into an array so it can create a new XML file. Basically I got the creating the XML file part down, but still need help with the rest of my stuff.
My goal is trying to take my form data and push it into my existing array, not overwrite it, add to it, so I can update my existing XML file with the new registration information. This is where I have absolutely no idea how to do. Some pointers would be nice.
By the way, my Professor purposely did not teach us how to do this because he wants us to research on it by ourselves.
Which should give you a hint about searching a bit more deeply. Anyhow, I'm not going to comment on every line, but I will offer some hints.
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
That is a Microsoft proprietary way of creating an XML document and it is normally wrapped in try..catch as different ActiveXObjects are provided in different versions of IE. You also need to look for document.implementation.createDocument.
//DEFINE LOAD METHOD
function LoadXML(xmlFile)
{
xmlDoc.load(xmlFile);
You might want to check out the async parameter.
xmlObj = xmlDoc.documentElement;
}
//declare & initialize array
var arrPerson = new Array();
It is considered better practice to use an array literal: ... = [];
//initialize array w/ xml
function initialize_array()
{
LoadXML("PersonXML.xml");
var x = 0;
while (x < xmlObj.childNodes.length)
Getting the length of xmlObj.childNodes on every loop is inefficient, consider storing the length and comparing with that value.
{
var tmpArr = new Array(xmlObj.childNodes(x).getAttribute("Usrname"),
xmlObj.childNodes(x).getAttribute("Pswd"),
xmlObj.childNodes(x).getAttribute("FirstName"),
xmlObj.childNodes(x).getAttribute("LastName"),
xmlObj.childNodes(x).getAttribute("DOB"),
xmlObj.childNodes(x).getAttribute("Gender"),
xmlObj.childNodes(x).getAttribute("Title"));
It is very inefficient to access xmlObj.childNodes(x) repeatedly. Store a reference and reuse it.
arrPerson.push(tmpArr);
You could assign the values directly to arrPerson and get rid of tmpArr.
x++;
Using a plain for loop will increment x for you.
}
}
//Validation
function LogInVal(objtxt)
{
if(objtxt.value.length == 0)
{
objtxt.style.background = "red";
return 1;
}
else
{
objtxt.style.background = "white";
return 0;
}
}
Not all browsers will let you style the background color of input elements.
//main validation
function MainVal(objForm)
{
var errmsg = "empty field";
var errmsg2 = "Incorrect Username and Password";
You might want a better way of naming the error messages and relating them to other information for that message. An object might do the job.
var msg = "You have logged in successfully";
var errCount = 0;
var usrn = document.getElementById("usrname1").value;
var pswd = document.getElementById("pswd1").value;
errCount += LogInVal(objForm.usrname);
errCount/*1*/ += LogInVal(objForm.pswd);
initialize_array();
if (errCount != 0)
{
alert(errmsg);
return false;
}
else if(authentication(usrn, pswd) == true)
The function authentication() returns true or false, so you don't need to compare it to anything, you can just test the returned value (i.e. there is no need for == true above).
{
alert(msg);
return true;
setCookie('invalidUsr',' ttttt');
}
else
{
alert(errmsg2);
return false;
}
}
Instead of showing alert messages one at a time in an alert, consider putting them in the document adjacent to the elements they relate to. That way the user can see the messaeg while fixing the error.
Isn't it cheating to ask us? Your implementation will probably only work in IE, I'd recommend using jQuery as it is impressively powerful at parsing XML.
I'm not sure why he wants you to write out XML as it's not very intuitive coming from JavaScript. You can do something like this via jQuery
//I capture form submitevent
$('form').submit(function( ev ){
ev.preventDefault(); //I keep form from submitting
$( xmlDocument ).find('Person').attr({
username: $("input[name=usrname]),
password: $("input[name=pswd]),
//and so on
});
});
It's up to you on how you 'report' this xml file
Here i am sharing my experience in writing html form data to xml.
Create one html file in one location (D:\\HtmlToXml.html).
And open it with Internet Explorer.
Then after provide information and click on submit button, then one file is created in the same directory with name example.xml.
If once an xml is created, then next time onwards on submit button click data will append to same xml file.

i'm developing a meta search engine website, Soogle and i've used JS to populate select menu..
Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it..
Is there a possibility to preselect one value from the menu via JS after the page loads?
This is the code:
Javascript:
// SEARCH FORM INIT
function addOptions(){
var sel=document.searchForm.whichEngine;
for(var i=0,l=arr.length;i<l;i++){
sel.options[i]=new Option(arr[i][0], i);
}
}
function startSearch(){
var searchString=document.searchForm.searchText.value;
if(searchString.replace(/\s+/g,"").length > 0){
var searchEngine=document.searchForm.whichEngine.selectedIndex,
finalSearchString=arr[searchEngine][1]+searchString;
window.location=finalSearchString;
}
return false;
}
function checkKey(e){
var key = e.which ? e.which : event.keyCode;
if(key === 13){
return startSearch();
}
}
// SEARCH ENGINES INIT
var arr = [
["Web", "http://www.google.com/search?q="],
["Images", "http://images.google.com/images?q="],
["Knowledge","http://en.wikipedia.org/wiki/Special:Search?search="],
["Videos","http://www.youtube.com/results?search_query="],
["Movies", "http://www.imdb.com/find?q="],
["Torrents", "http://thepiratebay.org/search/"]
];
HTML:
<body onload="addOptions();document.forms.searchForm.searchText.focus()">
<div id="wrapper">
<div id="logo"></div>
<form name="searchForm" method="POST" action="javascript:void(0)">
<input name="searchText" type="text" onkeypress="checkKey(event);"/>
<span id="color"></span>
<select tabindex="1" name="whichEngine" selected="Web"></select>
<br />
<input tabindex="2" type="button" onClick="return startSearch()" value="Search"/>
</form>
</div>
</body>
I appreciate that your question asks for a solution that utilises JavaScript, but having looked at the webpage in question I feel confident in making this point:
Your problem is that you are trying to use JavaScript for something that HTML itself was designed to solve:
<select name="whichEngine">
<option value="http://www.google.com/search?q=" selected="selected">Web</option>
<option value="http://images.google.com/images?q=">Images</option>
<option value="http://en.wikipedia.org/wiki/Special:Search?search=">Knowledge</option>
<option value="http://www.youtube.com/results?search_query=">Videos</option>
<option value="http://www.imdb.com/find?q=">Movies</option>
<option value="http://thepiratebay.org/search/">Torrents</option>
</select>
Fear not, though! You can still access all of the options from JavaScript in the same way that you did before.
function alertSelectedEngine() {
var e = document.getElementsByName("whichEngine")[0];
alert("The user has selected: "+e.options[e.selectedIndex].text+" ("+e.options[e.selectedIndex].value+")");
}
Please, forgive and listen to me.
I have modified the code to use jQuery. It is working fine in IE8, IE8 (Compatibility mode) and in FireFox.

You had some errors in how you handle the <select> values and options. I would reorganize your JavaScript like this:
// SEARCH ENGINES
var arr = [["Web", "http://www.google.com/search?q="],
["Images", "http://images.google.com/images?q="],
["Knowledge", "http://en.wikipedia.org/wiki/Special:Search?search="],
["Videos", "http://www.youtube.com/results?search_query="],
["Movies", "http://www.imdb.com/find?q="],
["Torrents", "http://thepiratebay.org/search/"]];
// SEARCH FORM INIT
function addOptions(){
var sel=document.searchForm.whichEngine;
for(var i=0;i<arr.length;i++) {
sel.options[i]=new Option(arr[i][0],arr[i][1]);
}
}
function startSearch(){
var searchString = document.searchForm.searchText.value;
if(searchString!==''){
var mySel = document.searchForm.whichEngine;
var finalLocation = mySel.options[mySel.selectedIndex].value;
finalLocation += encodeURIComponent(searchString);
location.href = finalLocation;
}
return false;
}
function checkKey(e){
var character=(e.which) ? e.which : event.keyCode;
return (character=='13') ? startSearch() : null;
}
I would also move your onload handler into the main body of your JavaScript:
window.onload = function() {
addOptions();
document.searchForm.searchText.focus();
};
I also made some changes to your HTML:
<body>
<div id="wrapper">
<div id="logo"></div>
<form name="searchForm" method="POST" action="." onsubmit="return false;">
<input name="searchText" type="text" onkeypress="checkKey(event);" />
<span id="color"></span>
<select tabindex="1" name="whichEngine" selected="Web"></select><br />
<input tabindex="2" type="button" value="Search"
onclick="startSearch();" />
</form>
</div>
</body>
You could specify which egine you would like preselected in the engines array like this:
// SEARCH ENGINES INIT
// I've used array literals for brevity
var arr = [
["Web", "http://www.google.com/search?q="],
["Images", "http://images.google.com/images?q="],
["Knoweledge", "http://en.wikipedia.org/wiki/Special:Search?search="],
/*
* notice that this next line has an extra element which is set to true
* this is my default
*/
["Videos", "http://www.youtube.com/results?search_query=", true],
["Movies", "http://www.imdb.com/find?q="],
["Torrents", "http://thepiratebay.org/search/"]
];
Then in your setup function:
// SEARCH FORM INIT
function addOptions() {
var sel = document.searchForm.whichEngine;
for (var i = 0; i < arr.length; i++) {
// notice the extra third argument to the Option constructor
sel.options[i] = new Option( arr[i][0], i, arr[i][2] );
}
}
if your only concern is preselecting an engine onload, don't "over-engineer" it.
var Web = "http://www.google.com/search?q=";
var Images = "http://images.google.com/images?q=";
var Knowledge = "http://en.wikipedia.org/wiki/Special:Search?search=";
var Videos = "http://www.youtube.com/results?search_query=";
var Movies = "http://www.imdb.com/find?q=";
var Torrents = "http://thepiratebay.org/search/";
function addOptions(source){
var sel=document.searchForm.whichEngine;
for(var i=0,l=arr.length;i<l;i++){
sel.options[i]=new Option(arr[i][0], i);
}
}
then insert your argument made onto your body tag to a pre-defined variable. If you want something random, create a new function with your equation for selecting a random variable then load your addOptions(function) within your new function. Then remove addOptions from your body tag.
<body onload="addOptions(Web);document.forms.searchForm.searchText.focus()">
