How would I make a textbox, containing preexisting text, that when the user clicked within it all the text inside it would become highlighted. For example, the same way YouTube does the textboxes for the embed code on their videos. Thanks
If I've understood your problem correctly, you could use some javascript (untested code):
<script language="JavaScript">
function selectText(textField)
{
textField.focus();
textField.select();
}
</script>
<input type="text" name="sometext" size="100" value="The Text" onClick='selectText(this);'>
You can put the script between your <head> and </head> tags.

I was trying to write my code here but for whatever reason the site prohibited me to. My code is essentially two texts with a button in the middle. Whatever you write in the first text it will be copied to the other text once you hit the button. I want to edit the code so that it does what it does and ALSO accepts values from the second text and copies to the first one. Thanks.
<html>
<head> <meta charset="utf-8"> </head>
<body>
<input type="text" value="" id="from" />
<button onclick="document.getElementById('to').value = document.getElementById('from').value">copy</button>
<input type="text" value="" id="to" />
</body> </html>
Use an on change for each of the text boxes. I'm a jQuery user but if you did it with standard JS you could do something like ... this is not full code ...
<textarea id='t1' name='t1' onChange="document.getElementbyId('t2').value=document.getElementbyId('t2').value"></textarea>
<textarea id='t2' name='t2' onChange="document.getElementbyId('t1').value=document.getElementbyId('t2').value">
</textarea>
Clicking the button would also trigger the change event. If you want it to copy the contents ONLY when the button is clicked, you could set a variable that stores the textarea id last changed and use that to determine which way to do the copy when the button is clicked.
Hey guys i was just wondering how to do this in a input type of text
when the user has not click the box. show "Edit Name" in the box with a slightly grey font color.
When the user clicks in the box it changes to "John Doe" and then they can edit it then submit
//EDIT
doesn't work as it already has a value set. i need the placeholder to show until clicked then the value shows
If you're using HTML5 the Placeholder attribute is the way to go.
If not just grab one of the many watermark scripts out there for jQuery or Javascript (e.g. jQuery Watermark.
EDIT
One manual way to do what you want with jQuery and CSS:
// CSS
#name{color:#ccc;}
// HTML
<input type="text" name="name" id="name" size="30" value="Edit Name" />
// jQuery
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#name').bind('focus', function() {
if ($(this).val() == 'Edit Name') {
$(this).val('John Doe').css('color', '#000');
}
});
});
</script>
Put the jQuery section in the code above into the <head> section of your HTML document and you should be good to go.
Newer browsers support the HTML5 placeholder attribute, which you can use as follows:
<input type="text" value="" placeholder="Edit Name">
For browsers that don't support it, various fallback scripts exist, which will automatically do their work if the attribute isn't supported.
Dive into HTML5 has a table of which browser versions support it natively, in case you're interested.
I have a textbox that has a piece of text in it already so users know what is supposed to go in it. I've already set it up so clicking on it selects all the text. What I want to know if how I can make it so clicking on the textbox will clear all the text. Likewise, if the user deletes everything they wrote, how can I make the original text appear?
A perfect example of what I want to do is the textbox for the title when asking a question here on Stack Overflow.
With the code below you can simply add the class "clear" to any input element or textarea and it will clear the initial value!!!
<!DOCTYPE html>
<html>
<head>
<title>Sample</title>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.min.js" type="text/javascript"></script>
<script>
$(function() {
$('.clear').one('focus', function() {
this.value = '';
});
});
</script>
</head>
<body>
<input type="text" value="Full Name" class="clear"/> <br />
<input type="text" value="Email" class="clear"/> <br />
<textarea value="About you..." class="clear"></textarea>
</body>
</html>
Fast and dirty, but does the job:
<input type="text" value="init..." onfocus="this.value=''; this.onfocus=null;" />
Update:
Since my answer in 2011 input placeholder became a common thing, so the proper solution is:
<input type="text" placeholder="init..." />
The textarea you created should have an id associated with it in the tag. The text area id would look something like this:
<textarea id="someId"...>
Where "someId" would be whatever name you give to it. Then when you use the following code
document.getElementById('someId').value = '';
it will replace the text in the box with the text specified by the function above. In this case, it will replace it with no text. Just make sure it only does this once, otherwise, when you click outside of the box, and then click inside of it again, the user's input will still be erased as well.
I'm trying to figure out how to call a method everytime a text box in a form's value changes.
For example,
Is there a parameter I can add that is called everytime the user types something new in the box? I know there is an "onchange" but that is only called once the user is done typing in that box.
Thanks!
What you need to us is an onkeyup event. Without a js library your code should look similar to this (syntax is unchecked):
<html>
<head>
<script type="text/javascript">
function keyup(x)
{
//code
}
</script>
</head>
<body>
Enter your name: <input type="text" id="fname" onkeyup="keyup(this)">
</body>
</html>
You can also use onblur if you want to check it when the user changes focus from the text box.

my application working well in all browsers except IE.
In my application I have a div popup form which contains some fields. In the text box it i pressed any key it was not displaying. If i move the mouse then the entered texts are displaying actual thing is screen not refreshed
How to solve this.
mycode:
<form>
//this is popup form
<div>
<form>
<input type="text"/>
<!-- if i type in the text box in IE it is not displaying but in some pc only -->
</form>
</div>
</form>
Thanks,
If i understand correctly, you want to have a popup, containing a form. The code you pasted is just html; it does not have any of this interactivity.
Let's start with your code. It has a form with a form inside it. The form tag is used to specify the start of a web form. You can specify several thing in this tag:
action: Where will the form be posted to? e.g. send the form to http://www.example.com/processform/
method: Will the form be submitted using the GET or POST method?
Having a second form tag inside it doesn't make sense: your browser will not know where to post the form to. Most browsers will choose to use one of the two tags, but they might choose the wrong one or ignore the form tags entirely.
If you want to have a form in a popup, use an approach like following html code:
<p><span id="clickablelink">Open the form</span></p>
<div class="dialog" style="display: none;">
<form action="/process/" method="post">
<input type="text" />
<input type="submit" name="submit" value="Submit this form" />
</form>
</div>
This code part should be inside the part of your html document.
You cannot open a dialog in the same page, unless you use JavaScript, jQuery or another framework to display this form. An example of this using jQuery UI:
<link type="text/css" href="css/themename/jquery-ui-1.7.1.custom.css" rel="Stylesheet" />
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.7.1.custom.min.js"></script>
<script type="text/javascript">
$(function() {
$(".dialog").dialog({
autoOpen: false
});
$("#clickablelink").click(function(){
$(".dialog").dialog("open");
});
});
</script>
This code block should be inside the part of your html document.
This is just a basic example. It might not be exactly what you are looking for. It is meant to show you in what directions you can look for your specific solution. I would suggest putting more details in your question:
For what purpose are you using this website?
What will this form be used for?
Why are you displaying a form inside a dialog?
Answering these questions and specifying your problem help you understand what you are trying to achieve and help us to answer your question properly.
