So I am trying to, when the button a is clicked, add the letter to the textfield. However, I cant seem to figure out why it isn't working. I got the code for it from here on stack exchange. Any help is as always appreciated.
<html>
<head>

<style>
tab1 { padding-left: 8em; }
tab2 { padding-left: 12em; }

<body style="background-color:powderblue;">
<tab2><input id="bar a" style="height:20px;width:120px" type="button" value="a" onlick=buttonPress('a')/><br><br>
<tab1><input id ="stringInput" type="text" value=""/><br>
<script language="javascript" type="text/javascript">
var added;
function buttonPress(added)
{
document.getElementById("bar a").addEventListener('click', function () {
var text = document.getElementById('stringInput');
text.text = (text.text + added);
});
}
</script>
</body>
</html>
You don't need to attach event as you are already calling function onclick.
Aslo you need value property of textbox not text
function buttonPress(added)
{
var text = document.getElementById('stringInput');
text.value= (text.value + added);
}
Also your html for button in invalid.It should be
<input id="bar a" style="height:20px;width:120px" type="button" value="a" onclick="buttonPress('a')" />

<script>
function addInput()
{
var test1_value= document.getElementById('test1').value;
var test2_value= document.getElementById('test2').value;
document.getElementById('test2').value=''+test2_value+''+test1_value;
}

There are few issues in your code. Not sure if it is a typo in your code.
For example onlick=buttonPress('a') . It should be onclick and the handler function should be quotes. Refer to the below html.
There is also no need of adding addEventListener inside function. You have already added the listener in the html code. If you add the listener inside the function, then on first click it will again try to add the the event.
Refer to the below js. Hope this will be useful
var added = " New Text";
function buttonPress(added) {
var text = document.getElementById('stringInput');
text.value = (text.value + added);
}
HTML
<input id="bar" style="height:20px;width:120px" type="button" value="a" onclick='buttonPress("a")' />
DEMO
your onclick is mispelled as onlick. This will be read as a custom attribute.
put the buttonPress('a') inside "". It will become onclick="buttonPress('a')". It prompts an error when it's not inside "".
since you are using an input for the component with id "stringInput", text property does not work so you have to use the value property instead.

So I have an input type file and textarea. I want to show the file name in textarea on input type file change. Here I have reached something, but this works only for the first time and when I write some text and want to select another file I don't get that file name in textarea.

$('#file').change(function () {

$('#list').append(value);
});
$('#submit').click(function() {
var a = getElementById('list').value;
getElementById('demo') = a;
});
</script>

You need to use .value or .innerHtml after write manually in textarea.
For example change this:
$('#list').append(value);
into:
$('#list').val($('#list').val()+value);
should works.
I am currently working in jsp. I need to get the value of input on text box while a buttton is clicked. My code is given below. While running it produces output which disappears in seconds. I need a stable output (text in textbox) when button is clicked.
<html>
<head>
<style type="text/css">
body {
background-color: #cccccc;
}
tab{ padding-left: 4em; }
</style>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<form>
<title>Businesscard Management</title>
</head>
<body>
<br><br><br><br><br><br>
<h2> Search : <input type="text" class="textbox" size="75" id="myText" autofocus="true" name="searchinput"/></h2>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
document.getElementById("myText").value="ertyu";
}
</script>
</body>
</html>
First of all you have some errors in your code markup. You have just one opened <form> tag inside of <head> tag. Also I noticed that you're trying to set styles for tab but this is not appropriate tag. And you forgot to close </html> tag. Be careful when writing code, better to use code indention for better reading and it could prevent plenty of errors.
regarding your code:
<html>
<head>
<style type="text/css">
body {
background-color: #cccccc;
}
tab {
padding-left: 4em;
}
</style>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Businesscard Management</title>
</head>
<body>
<br><br><br><br><br><br>
<form action="/">
<h2> Search : <input type="text" class="textbox" size="75" id="myText" autofocus="true" name="searchinput"/></h2>
<input type="button" onclick="myFunction()" value="Try it"/>
<p id="demo"></p>
</form>
<script>
function myFunction() {
document.getElementById("myText").value = "ertyu";
}
</script>
</body>
</html>
I've move <form> tag to it desired position. And replaced <button> with <input type="button"> to prevent form submitting. So regarding your code when you press Try it button you will assign "ertyu" text to the input value. And if you want to get value of it, just use document.getElementById("myText").value
I'm making a prototype for a chat client. At this stage, I'm just learning how to append the user's input to the text area above. However, no matter what I do, it doesn't seem to work. The only time it actually functioned correctly was in jsfiddle, but I can't get it to work when I load my actual HTML page.
It's worth mentioning that, at the advice of a tutorial, I already tried placing the script tag for my JQuery code at the end of the body instead of in the head. The tutorial said that it was essential for all elements be allowed to load before the JQuery code, so that's the way it had to be. As you can see below, the script tags are currently in the head, but that doesn't work either.

<h2 ID="header">Chat Client</h2>
<div ID="chatBox">
<div ID="topBar2">
</div>
<div ID="header2">

</div>
<textarea ID="textArea" name="textArea">

<form ID="in">
<input ID="textField" type="text">
<button ID="send" type="button" name="Send" value="send">Send</button>

Chat.js
function sendText(){
$(document).ready(function () {
$('#send').click(function () {
var text = $('#textField').val();
$('#textArea').val($('#textArea').val() + text);
$('#textField').val('');
});
});
}
Don't wrap document ready handler inside sendText() function, use that instead:
$(document).ready(function () {
$('#send').click(sendText);
});
function sendText(){
var text = $('#textField').val();
$('#textArea').val($('#textArea').val() + text);
$('#textField').val('');
}
Well, it work if you change your button to submit type and bind the event to form submit:
$('#in').submit(function () {
var text = $('#textField').val();
$('#textArea').val($('#textArea').val() + text);
$('#textField').val('');
return false;
});
http://jsfiddle.net/AztSB/
This seems to work for me:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="ChatStyle.css"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('#send').click(function () {
var text = $('#textField').val();
$('#textArea').html($('#textArea').html() + text);
$('#textField').val('');
});
});
</script>

<form ID="in">
<input ID="textField" type="text">
<input ID="send" type="button" name="Send" value="send"/>
</form>
</div>
</body>
</html>
Just don't wrap it in your function sendText:
$(document).ready(function () {
$('#send').click(function () {
var text = $('#textField').val();
$('#textArea').val($('#textArea').val() + text);
$('#textField').val('');
});
});
You dont need to put it in a function. You can just leave it to Jquery :)
Your stuff in a FIDDLE to see
Jquery:
$('#send').click(function () {
var text = $('#textField').val();
$('#textArea').append(text);
$('#textField').val('');
});
UPDATE
Use append() to update the textarea with new text!
It always seems to be a problem and I fail to see why, I'm trying to change element p text by using his ID, element p id="para1" is inside PostEditor.html:
The elementID I want to change is para1 in the following html:
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<link href="styles/editor.css" rel="stylesheet" type="text/css" media="screen" />
<script src="scripts/mainScript.js"> </script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="submit" onclick="urlLoader('caller','posthandler.php')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>
</html>
The following function is issued by a click on a link inside index.html and displaying the page you are seeing above and is then supposed to change its content:
From index.html I issue the function from link:
<a onclick="postEditing()"> Edit</a>
This line issue the following function:
function postEditing()
{
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.document.getElementById("para1").innerHTML = "11111111111";
result.document.getElementById("para1").innerText = "11111111111";
result.document.getElementById("para1").value = "11111111111";
}
As you can see I tried three methods. I'd never understand what is the difference between them, but I tried all three and none worked!
It's because you're searching the document of the window which shows the index.html, not the document of the newly opened window. try following:
...
var editorWindow = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
editorWindow.document.getElementById("para1").innerHTML = "11111111111";
...
EDIT:
NOW i see the problem: in the function you're trying to access a property of the parameter element, but you don't pass a value for it. So this will end in an error because the accessed object is undefinded!
So you have three options to get it working:
test the parameter (always a good idea): var ID = null; if(element) ID = element.id;
pass a value: <a onclick="postEditing(this)"> Edit</a>
remove the line var ID = element.id;
SOLUTION: (TESTED)
I could not really say why, but the index.html found the para1 and can successfully set the new text. But somehow the new window will reinitialize the old value again.
So you have to do the changing in an handler you run at onLoad:
index.html:
<html>
<head>
<script>
function postEditing() {
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.onload = function() {
result.document.getElementById("para1").innerHTML = "11111111111";
}
}
</script>
</head>
<body>
<a onclick="postEditing()"> Edit</a>
</body>
</html>
PostEditor.html:
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<link href="styles/editor.css" rel="stylesheet" type="text/css" media="screen" />
<script src="scripts/mainScript.js"> </script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="submit" onclick="urlLoader('caller','posthandler.php')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>
</html>
I'm fairly sure you will need to query the return result of calling window.open like this:
function postEditing(element)
{
var ID = element.id;
var result = window.open('PostEditor.html', 'newwindow', 'width=350,' + 'height=350');
result.getElementById("para1").innerHTML = "11111111111";
result.getElementById("para1").innerText = "11111111111";
result.getElementById("para1").value = "11111111111";
}
[Untested though]
Your button type is submit, which is posting the form. The object is changing in the DOM, only after the script runs, the DOM is reloaded back to it's original state. Try changing your button type to "button", and you should see the P element change appropriately.
Edit: Here's the HTML I used to determine the above. Keeping the button as "submit" caused me to see the text change and then swap back. The HTML below should keep the text in place. HTH!
<!DOCTYPE html>
<html>
<head>
<title>Editor</title>
<script>
function postEditing(element)
{
document.getElementById('para1').innerHTML = "asdafs";
}
</script>
</head>
<body>
<!-- Input fields -->
<div class="center">
<form id=caller method="post">
<p id="para1" class="text"><Strong>Post your message</Strong></p>
<textarea id="textEditor" rows="16" cols="34" name="content"></textarea>
<input type="button" onclick="postEditing('caller')" value="Post">
</form>
</div>
<!-- end Input fields -->
</body>

I'd like to display a div on a webpage when a user clicks on a button.
Does someone know how to do this ?
My code, so far, is :
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso 8859-1" />
</head>
<body>
<input id="text" type="text" size="60" value="Type your text here" />
<input type="button" value="When typing whatever text display the div balise on the page" onclick="check();" />
<script type="text/javascript">
function check() {
//Display my div balise named level0;
}
</script>
</body>
</html>
Thanks,
Bruno
EDIT: All my code (I've erased it because it was too long and not very clear)
You can use document.createElement("div") to actually make the div. Then you can populate the div using innerHTML for the text. After that, add it to the body using appendChild. All told, it can look like this:
function check() {
var div = document.createElement("div");
div.innerHTML = document.getElementById("text").value;
document.body.appendChild(div);
}
This will add a div every time the button is pressed. If you want to update the div each time instead, you can declare the div variable outside the function:
var div;
function check() {
if (!div) {
div = document.createElement("div");
document.body.appendChild(div);
}
div.innerHTML = document.getElementById("text").value;
}
If you have the div already in the page with an id of "level0", try:
function check() {
var div = document.getElementById("level0");
div.innerHTML = document.getElementById("text").value;
}
A quick search on google gave me this example:
Demo of hide/show div
The source-code for that example is:
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<html>
<head>
<title>Demo of Show hide div layer onclick of buttons</title>
<META NAME="DESCRIPTION" CONTENT="Displaying and hiding div layers through button clicks">
<META NAME="KEYWORDS" CONTENT="Show layer, hide layer, display div, hide div, button on click, button on click event, div property, div style set">
<style type="text/css">
div {
position: absolute;
left: 250px;
top: 200px;
background-color: #f1f1f1;
width: 280px;
padding: 10px;
color: black;
border: #0000cc 2px dashed;
display: none;
}
</style>
<script language="JavaScript">
function setVisibility(id, visibility) {
document.getElementById(id).style.display = visibility;
}
</script>
</head>
<body>
<input type=button name=type value='Show Layer' onclick="setVisibility('sub3', 'inline');";><input type=button name=type value='Hide Layer' onclick="setVisibility('sub3', 'none');";>
<div id="sub3">Message Box</div>
<br><br>
</body>
</html>
Paste this code somewhere in your body
<div id="myDiv" style="display:none">
Hello, I am a div
</div>
Add this snippet into your check() function to display the otherwise-hidden content.
document.getElementById("myDiv").style.display = "block";
You could also change the div content programmatically thus:
document.getElementById("myDiv").innerHTML = "Breakfast time";
... would change the text to 'Breakfast time'.
You might want to look into jquery, it'll make your life 100 times easier.
Jquery is a javascript library (script) that you include and it allows you to manipulate the DOM very easily.
Start by adding the latest Jquery to your head which will allow you to use something like $(document).ready( )
The function inside .ready( fn ) is a callback function; it get called when the document is ready.
$("#lnkClick") is a selector (http://api.jquery.com/category/selectors/)
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready( function() {
$("#lnkClick").click( function() {
$("#level0").attr("style", "display: block;width: 100px; height: 100px; border: solid 1px blue;");
});
});
</script>
</head>
<body>
<div id="level0" style="display:none;">
</div>
Click me
</body>
</html>
Of course this code can be made cleaner. You want to check: http://api.jquery.com/click/
There are plenty of examples.
Best of luck with Jquery!
you really should be using jquery , there's a little bit of a learning curve but once you get it, developing web apps is much easier.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.5.2.min.js"></script>
