I'm currently working on a project where I'm writing a webpage that gives basic diagrams about human anatomy. What I'm currently testing is the ability to switch dynamically between different images at the press of a button using a Javascript function, so that the user will eventually be able to switch between different views of the human body.
This is the code that I have so far.
<!DOCTYPE html>
<html lang="en">
<head>
<script>
function skin()
{
document.getElementById("image").src="humanoutline.jpg";
}
function muscle()
{
document.getElementById("image").src="humanoutline2.jpg";
}
function organs()
{
document.getElementById("image").src="humanoutline3.jpg";
}
function skeleton()
{
document.getElementById("image").src="humanoutline4.jpg";
}
</script>
</head>
<body>
<style>
.button
{
background-color: green;
border-radius: 4px;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
}
#image
{
position:absolute;
width:500px;
height:700px;
z-index: 0;
top: 30%;
left: 45%;
padding:50px;
margin: -100px 0 0 -200px;
text-align:center;
align-content:center;
outline-style:solid;
outline-width:1px;
outline-color:black;
}
#rightside
{
text-align:center;
width:400px;
height:1000px;
padding: 30px;
line-height: 100px;
float:right;
outline-style:solid;
outline-width:1px;
outline-color:black;
}
</style>
<div id="rightside">
<p>Select Layer</p>
<form>
<button class="button" onclick="skin()">Skin</button><br>
<button class="button" onclick="muscle()">Muscle</button><br>
<button class="button" onclick="organs()">Organs</button><br>
<button class="button" onclick="skeleton()">Skeleton</button><br>
</form>
</div>
<div>
<img id="image" src="humanoutline.jpg" alt="Body" style="width:464px;height:700px; ">
</div>
</body>
</html>
While this should work in theory, the problem is that whenever each of the buttons is pressed, the page only partially loads the new image and then switches back to the default image, which is humanoutline.jpg.
For reference, here are the four images that I'm currently using.
humanoutline.jpg:
humanoutline2.jpg:
humanoutline3.jpg:
humanoutline4.jpg:
The issue is that the button is "submitting" the form, which causes the page to reload.
The simple solution is to modify your functions as follows:
function skin() {
document.getElementById("image").src="humanoutline.jpg";
// the "return false" will cause the button to NOT submit the form
return false;
}
however your code as written so far is going to get large quickly, and be difficult to maintain, so I'd like to suggest / offer an alternative method of doing this.
You can change your buttons to call the same function, but pass in the parameter that is relevant. Additionally, they should return, see below:
<form>
<button class="button" onclick="return changeImage('humanoutline.jpg')">Skin</button><br>
<button class="button" onclick="return changeImage('humanoutline2.jpg')">Muscle</button><br>
<button class="button" onclick="return changeImage('humanoutline3.jpg')">Organs</button><br>
<button class="button" onclick="return changeImage('humanoutline4.jpg')">Skeleton</button><br>
</form>
And also change your script to accept a parameter, and use that in the image:
function changeImage(img) {
document.getElementById("image").src=img;
return false;
}
You just need to add type="button" to the <button> tags, like this:
<form>
<button type="button" class="button" onclick="skin()">Skin</button><br>
<button type="button" class="button" onclick="muscle()">Muscle</button><br>
<button type="button" class="button" onclick="organs()">Organs</button><br>
<button type="button" class="button" onclick="skeleton()">Skeleton</button><br>
</form>
And here's a codepen with the change that's working (though the image URLs are hotlinked from the uploads in this SO question, so I'm not sure if they'll keep working): http://codepen.io/anon/pen/GZZJVv
I've been trying to do a radio button checker with HTML and java script. When I click the 'check' button, it changes the inner-html to a paragraph. For some reason, the text only shows for about a half second then disappears.
JS file:
function runQuestionCheck() {
var question_one_answer = 1;
var question_two_answer = 1;
var question_three_answer = 1;
var question_one_explanation = "Text explaining why that's stupid!";
var question_two_explanation = " ";
var question_three_explanation = " ";
var question_one = document.getElementById("question_1").childNodes;
if (question_one[question_one_answer].isChecked) {
document.getElementById("q1_response").class = "correct";
document.getElementById("q1_response").innerHTML = "Correct!";
}
else
{
document.getElementById("q1_response").innerHTML = ("Sorry, that's incorrect." + question_one_explanation);
}
}

The reason you're seeing only a flash of text is because the text is being displayed, and then the page is immediately being refreshed. That's caused by the fact that your check button is inside a form. Since the form doesn't have an action or a method set, it defaults to submitting to the current page, via GET, which is basically the same as refreshing the page.
Looking at your code, you have a lot of forms that you probably don't need. You're not sending the data anywhere, you're just checking it locally in JavaScript. However, to remove all of them, your JavaScript code would need to be significantly overhauled, so to avoid that you can solve this problem either of these two ways:
Removing the form from your button
Right now it's not doing anything at all. Just get rid of it and you won't have a problem. Replace
<form>
<button onclick="runQuestionCheck()">Check answers!</button>
</form>
With
<button onclick="runQuestionCheck()">Check answers!</button>
Or, Add a type attribute to the button
The button defaults to being a submit button, which will submit whatever form it's in when it's clicked. That's what we want to avoid, so you can instead set it to be just a normal button, like this:
<form>
<button onclick="runQuestionCheck()" type="button">Check answers!</button>
</form>
If you want to keep the form, then this is your best option.
Your code has some other problems, too.
Your style should go in the head.
Your links (Back to Home and Highlight facts) should not be in the head, they should be in the body. Content never goes in the head.
Your script can't just be in the middle of nowhere. It has to go in either the head or the body. Nowadays it's generally recommended to put it in the body.
You shouldn't use FONT tags to style your text, you should use CSS. To put everything in Arial, you can put this in your style tag:
body {
font-family: arial;
}
Your JavaScript will encounter an error. The correct way to change an element's class in JavaScript is className. Replace this:
document.getElementById("q1_response").class = "correct";
With this:
document.getElementById("q1_response").className = "correct";
I have a menu bar. Now as per my need I have to open a login form as soon as menu bar menu is clicked. I have seen opening a jQuery dialog box with screen lock as soon as the URL is clicked and if the user has provided the correct Username and Password he will navigate to the required page else dialog box in screen Lock will say "Please Enter Correct Username and Password".
Here is my menu bar link code in HTML.
<div>
<ul>
<li>ExtensionWise</li>
<li>Call Type</li>
</ul>
</div>
What you are trying to get is called as modal behaviour where a dialog disables all other elements on the page from being interacted. There are many ui-plugins out there for this but you can also create your own custom div to act in a modal dialog type of behaviour using jQuery and CSS.
html
<div id="box" align="center"></div>
<form>User Name:
<input type="text" name="firstname" />
<br/>Password:
<input type="password" name="pwd" />
<input type="submit" />
<button type="button" id="cancel">Cancel</button>
</form>
<a id="login" href="#">Click to Login</a><br/>
<a id="alert" href="#">Click To Alert before and after opening form</a>
script
$(document).ready(function(){
$('#alert').click(function(){alert('alert')})
$('a#login').click(function(){
$("#box,form").fadeIn('slow');
})
$('#cancel').click(function(){
$('#box,form').hide();
})
})
css
div {
width: 100%;
height: 100%;
display:none;
position: absolute;
z-index:100;
background: lightgreen;
opacity: 0.6;
}
form{
position: absolute;
z-index: 101;
display:none;
width: 200px;
border: 2px solid red;
margin-top:50px;
margin-left: 200px;
background: cornflowerblue;
}
Note:- you must put the div and form always as the topmost element in the body

I'm am very sorry if this has been asked before but I cannot find it anywhere.
I am fairly new to web development in all aspects, but decided to create a nice little application to access and search a database from anywhere in the office.
I followed several tutorials using WebMatrix on how to set up a simple webpage etc and I have it mostly working, except for dealing with going to the next page in WebGrid. Here is what im talking about (kind of obscure but it cannot be helped)
I found two examples online about trying to use javascript and they gave me these bits of code to use..
In a file called _layout.cshtml
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Start</title>
<script src="#Href("~/scripts/jquery-1.6.2.min.js")" type="text/javascript"></script>
<link href="#Href("~/styles/site.css")" rel="stylesheet" />
#RenderSection("script", required: false);
</head>
<body>
#RenderBody();
</body>
</html>
Then a file called _PageStart.cshtml
#{
Layout = "~/_layout.cshtml";
}
Then I started creating my own site and modeling it after a few tutorials I had seen, specifically involved around the WebGrid.
This is my Default.cshtml
#{
string searchStr = Request["searchBox"];
string choice = Request["choice"];
Database db = Database.Open("NameOfDatabase");
if(choice == null)
{
choice = "DefaultColumnName"; // they choose which column they want to search
//via radio buttons
}
var queryStr = "SELECT * FROM databaseTable WHERE "+choice
+" LIKE '"+searchStr+"%'";
var data = db.Query(queryStr);
WebGrid grid = new WebGrid(source: data,
defaultSort: "Name",
rowsPerPage: 20, canPage:true, canSort:true);
if(IsPost)
{//not really doing anything here
}
}
<head>
<title>Database</title>
<style type="text/css"> " //added that because it was goofing up the color scheme..
.grid { margin: 4px; border-collapse: collapse; width: 600px; }
.head { background-color: #E8E8E8; font-weight: bold; color: #FFF; }
.grid th, .grid td { border: 1px solid #C0C0C0; padding: 1px; }
.alt { background-color: #E8E8E8; color: #000; }
.style1{ min-width: 300px; max-width:400px; font-weight:bold; white-space:nowrap; overflow:hidden;}
.style2{ min-width: 100px; max-width:150px; overflow:hidden;}
.style3{ min-width: 200px; max-width:250px; overflow:hidden; white-space:nowrap;}
.style4{ min-width:100px; max-width:200px; overflow:hidden; }
.style5{ min-width: 150px; max-width:250px; overflow:hidden; white-space:nowrap;}
.style6{ min-width: 200px; max-width:250px; overflow:hidden;}
</style>
</head>
<body onload="document.form1.searchBox.focus();">
<h1>Database</h1>
<form name="form2" method="post" action="">
<p><input type="submit" name="populate" value="Populate DB" /></p>
</form>
<div id="grid">
#grid.GetHtml(
tableStyle: "grid",
headerStyle: "head",
alternatingRowStyle: "alt",
columns: grid.Columns(
grid.Column("Name","Name",
format: #<p title="#item.Name.Trim()">#item.Name</p>,
style:"style1"),
//repeat to create 5 more columns exactly the same essentially
), mode: WebGridPagerModes.All
)
</div>
<form name="form1" method="post" action="Default">
<p><label for="searchBox">Search:</label>
<input type="text" name="searchBox" value="#searchStr" /></p>
<p><input type="radio" name="choice" value="Name" />
<label for="Name">Name</label></p>
<p><input type="radio" name="choice" value="choice1" />
<label for="choice1">choice1</label></p>
<p><input type="radio" name="choice" value="choice2" />
<label for="choice2">choice2</label></p>
<p><input type="radio" name="choice" value="choice3" />
<label for="choice3">choice3</label></p>
<p><input type="radio" name="choice" value="choice4" />
<label for="choice4">choice4</label></p>
<p><input type="radio" name="choice" value="choice5" />
<label for="choice5">choice5</label></p>
<p><input type="submit" name="Submit" value="Submit" /></p>
</form>
</body>
#section script{
<script type="text/javascript">
$(function () {
$('th a, tfoot a').live('click', function () {
$('form1').attr('action', $(this).attr('href')).submit()
return false;
});
});
</script>
}
That is my website in general.. Well whenever you enter say someones name and a choice and click submit, it queries it fine, but if there are more than 20 names then when i click on the second page it essentially redoes my orginial query to get all the names and i loose what they typed into the text field and which option they choose.
The script I found is supposed to fire whenever they user clicks on the links that the webgrid creates to go to the next page, and put the data from form1 into something so that I can pull it back out when the page is loaded again.
I have looked and looked online for a solution and if I have found one I havent understood how it works.. so if anyone out there understands what I'm talking about and could help me out it would be greatly appreciated.
Thanks!

This question already has answers here:
Styling an input type="file" button
(46 answers)
Closed 7 years ago.
I would like to style <input type="file" /> using CSS3.
Alternatively, I would like user to press on a div (that I will style) and this will open the Browse window.
Is that possible to do that using HTML, CSS3, and Javascript / jQuery only ?
I have this rough example that you might want to get some idea...
html
<div id="file">Chose file</div>
<input type="file" name="file" />
CSS
#file {
display:none;
}
jQuery
var wrapper = $('<div/>').css({height:0,width:0,'overflow':'hidden'});
var fileInput = $(':file').wrap(wrapper);
fileInput.change(function(){
$this = $(this);
$('#file').text($this.val());
})
$('#file').click(function(){
fileInput.click();
}).show();
demo
After checking Reigels idea, and this one, I wrote this simple solution to the common problem of styling a type="file" input field (tested it on Firefox, Safari and Chrome).
<div style="position:relative;">
<div id="file" style="position:absolute;">Click here to select a file</div>
<input type="file" name="file" style="opacity:0; z-index:1;" onchange="document.getElementById('file').innerHTML = this.value;">
</div>
Then you can of course style the "file" div as you want.
And if you want to use a type="text" input instead of a div, simply change innerHTML for value:
<div style="position:relative;">
<input type="text" id="file" style="position:absolute;" placeholder="Click here to select a file">
<input type="file" name="file" style="opacity:0; z-index:1;" onchange="document.getElementById('file').value = this.value;">
</div>
Here is my original answer using jQuery:
<div style="position:relative;">
<div id="file" style="position:absolute;">Click here to select a file</div>
<input type="file" name="file" style="opacity:0; z-index:1;" onchange="$('#file').text($(this).val());">
</div>
I made a custom style for this as well. Check it out
JS Fiddle Demo - Custom Input type="file"
HTML
<input type="file" id="test">
<div class="button-group">
Browse
Save
Clear
</div>
<input type="text" id="testfile"></input>
CSS
body {
padding:100px;
}
input[type="file"] {
position:absolute;
display:none;
}
#testfile {
height: 26px;
text-decoration: none;
background-color: #eee;
border:1px solid #ccc;
border-radius:3px;
float:left;
margin-right:5px;
overflow:hidden;
text-overflow:ellipsis;
color:#aaa;
text-indent:5px;
}
#actionbtnBrowse, #actionbtnSave {
margin:0 !important;
width:60px;
}
JQuery
$("#browse").click(function () {
$("#test").click();
})
$("#save").click(function () {
alert('Run a save function');
})
$("#clear").click(function () {
$('#testfile').val('');
})
$('#test').change(function () {
$('#testfile').val($(this).val());
})
Also add to external resources tab:
https://github.com/necolas/css3-github-buttons/blob/master/gh-buttons.css
Here is how to do it using HTML, CSS and Javascript (without any frameworks):
The idea is to have the <input type='file'> button hidden and use a dummy <div> that you style as a file upload button. On click of this <div>, we call the hidden <input type='file'>.
Demo:
// comments inline
document.getElementById("customButton").addEventListener("click", function(){
document.getElementById("fileUpload").click(); // trigger the click of actual file upload button
});
document.getElementById("fileUpload").addEventListener("change", function(){
var fullPath = document.getElementById('fileUpload').value;
var fileName = fullPath.split(/(\\|\/)/g).pop(); // fetch the file name
document.getElementById("fileName").innerHTML = fileName; // display the file name
}, false);
body{
font-family: Arial;
}
#fileUpload{
display: none; /* do not display the actual file upload button */
}
#customButton{ /* style the dummy upload button */
background: yellow;
border: 1px solid red;
border-radius: 5px;
padding: 5px;
display: inline-block;
cursor: pointer;
color: red;
}
<input type="file" id="fileUpload"> <!-- actual file upload button -->
<div id="customButton">Browse</div> <!-- dummy file upload button which can be used for styling ;) -->
<span id="fileName"></span> <!-- the file name of the selected file will be shown here -->
The fake div is not needed! No Js no extra html. Using only css is possible.
The best way is using the pseudo element :after or :before as an element overt the de input. Then style that pseudo element as you wish. I recomend you to do as a general style for all input files as follows:
input[type="file"]:before {
content: 'Browse';
background: #FFF;
width: 100%;
height: 35px;
display: block;
text-align: left;
position: relative;
margin: 0;
margin: 0 5px;
left: -6px;
border: 1px solid #E0E0E0;
top: -1px;
line-height: 35px;
color: #B6B6B6;
padding-left: 5px;
display: block;
}
--> DEMO
In addition of Reigel,
here is more simpler implementation. You can use this solution on multiple file input fields, too. Hope this helps some people ;-)
HTML (single input)
<input type="file" name="file" />
HTML (multiple input)
<!-- div is important to separate correctly or work with jQuery's .closest() -->
<div>
<input type="file" name="file[]" />
</div>
<div>
<input type="file" name="file[]" />
</div>
<div>
<input type="file" name="file[]" />
</div>
JavaScript
// make all input fields with type 'file' invisible
$(':file').css({
'visibility': 'hidden',
'display': 'none'
});
// add a textbox after *each* file input
$(':file').after('<input type="text" readonly="readonly" value="" class="fileChooserText" /> <input type="button" value="Choose file ..." class="fileChooserButton" />');
// add *click* event to *each* pseudo file button
// to link the click to the *closest* original file input
$('.fileChooserButton').click(function() {
$(this).parent().find(':file').click();
}).show();
// add *change* event to *each* file input
// to copy the name of the file in the read-only text input field
$(':file').change(function() {
$(this).parent().find('.fileChooserText').val($(this).val());
});
Here's an example that I'm using that utilizes jQuery, I've tested against Firefox 11, and Chrome 18, as well as IE9. So its pretty compatible with browsers in my book, though i only work with those three.
HTML
Here's a basic "Customizable" HTML structure.
<span>
File to Upload<br />
<label class="smallInput" style="float:left;">
<input type="file" name="file" class="smallInput" />
</label>
<input type="button" class="upload" value="Upload" style="float:left;margin-top:6px;margin-left:10px;" />
</span>
CSS
Here's a sample of my CSS
label.smallInput {
background:url(images/bg_s_input.gif) no-repeat;
width:168px;
}
JavaScript
This is the heavy lifter.
/* File upload magic form?? */
$("input.smallInput[type=file]").each(function(i){
var id = "__d_file_upload_"+i;
var d_wrap = $('<div/>').attr('id',id).css({'position':'relative','cursor':'text'});
$(this).wrap(d_wrap).bind('change blur focus keyup click',function(){
$("#"+id+" input[type=text]").val($(this).val());
}).css({'opacity':0,'zIndex':9999,'position':'absolute'}).removeClass('smallInput');
obj = $(this);
$("#"+id).append($("<input/>").addClass('smallInput').attr('type','text').css({'zIndex':9998,'position':'absolute'}).bind('click',function(e){obj.trigger('click');$(this).blur();}));
obj.closest('span').children('input.upload[type=button]').bind('click',function(e){
obj.trigger('click');
$(this).blur();
});
});
/* ************************ */
Explanation
The HTML is pretty straight forward, just a simple element, i include the button so it can be named independently from the rest, sure this could be included in the JavaScript, but simply put, I'm a bit on the lazy side. The code searches for all inputs with a class of smallInput that have the type of file this allows you to define default HTML and fallback form structure in case a browser decides to be a pain.
This method only uses JavaScript to ensure delivery, it does not alter any browser behaviors in regards to the file input.
You can modify the HTML and JavaScript to make it very robust, this code suffices my current project so i doubt I'll be making any changes to it.
Caveats
Different browsers treat the value of the file input differently, which in chrome results in c:\fakeroot\ on windows machines.
Uses anonymous functions, (for lack of a better word) which means if you have too many file inputs you can cause the browser to behave slowly on processing.
Ran into the same issue today, but it seems there's an easy way to have your own styles - hide the input, and style the associated label:
<div class="upload">
<label for="my-input"> Upload stuff </label>
<input type="file" id="my-input" name="files[]" />
</div>
CSS:
.upload input{
display: none;
}
.upload label{
background: DarkSlateBlue;
color: white;
padding: 5px 10px;
}
Works in latest Chrome, Firefox and IE 10. Didn't test others
While Reigel's answer conveys the idea, it doesn't really have any style attached to it. I came across this problem recently and despite the plethora of answers on Stack Overflow, none really seemed to fit the bill. In the end, I ended up customizing this so as to have a simple and an elegant solution.
I have also tested this on Firefox, IE (11, 10 & 9), Chrome and Opera, iPad and a few android devices.

$('input[type=file]').change(function(e) {

Hope this helps!!!
Here is a solution with a text field where the user types in the (relative) pathname of the file copy on the server (if authorized) and a submit button to browse the local system for a file and send the form:
<form enctype="multipart/form-data" action="" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
<p><input type="file" name="upload_file" id="upload_file" size="40"/></p>
<p><input type="text" id="upload_filename" name="upload_filename" size="30" maxlength="100" value="<?php echo htmlspecialchars($filename, ENT_COMPAT, 'UTF-8'); ?>"/>
<input type="submit" class="submit submit_upload" id="upload_upload" name="upload_upload" value="Upload"/></p>
</form>
The scripting part hides the file input, clicks it if the user clicks on the submit button, submits the form if the user has picked up a file. If the user tries to upload a file without entering a filename, the focus is first moved to the text field for the filename.
<script type="text/javascript">
var file=$('#upload_file');
var filename=$('#upload_filename');
var upload=$('#upload_upload');
file.hide().change(function() {if (file.val()) {upload.unbind('click').click();}});
upload.click(function(event) {event.preventDefault();if (!filename.val()) {filename.focus();} else {file.click();}});
</script>
Simply style the submit button for a perfect result:
.submit {padding:0;margin:0;border:none;vertical-align:middle;text-indent:-1000em;cursor:pointer;}
.submit_upload {width:100px;height:30px;background:transparent url(../images/theme/upload.png) no-repeat;}
This is my method if i got your point
HTML
<form action="upload.php">
<input type="file" id="FileInput" style="cursor: pointer; display: none"/>
<input type="submit" id="Up" style="display: none;" />
</form>
jQuery
<script type="text/javascript">
$( "#FileInput" ).change(function() {
$( "#Up" ).click();
});
</script>
When you retreive the value of an input field, browser will return a fake path (literally C:\fakepath[filename] in Chrome). So I would add the following to the Javascript solutions:
val=$('#file').val(); //File field value
val=val.replace('/','\\'); //Haven't tested it on Unix, but convert / to \ just in case
val=val.substring(val.lastIndexOf('\\')+1);
$('#textbox').val(val);
Ofc, it could be done in a single line.
