The following jQuery example should put some text into the div, but it doesn't. I tried Firefox, Google Chrome and Internet Explorer.
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" language="javascript"></script>
<script language="javascript">
$(window).load(function() {
$('adiv').html('<p>hello world</p>');
alert('done');
});
</script>
</head>
<body>
<div id="adiv">
</div>
</body>
</html>
Sorry, this might be stupid, but I'm stuck.
change $('adiv').html('<p>hello world</p>');to
$('#adiv').html('<p>hello world</p>');
You're not actually selecting anything in your select function
Directly after your $( opening, you need to use a CSS3 valid selector. Just a string won't select anything unless it's a HTML element (table, div, h2)
You need to preface it with a . or a # to signal either a class or ID name.
$('adiv') should be $('#adiv').
Unlike Prototype, in jQuery you specify a CSS selector, not just a string that is implicitly inferred to be an ID. I find myself forgetting this from time to time.
As e-turhan already mentioned you need # in front of adiv in your $() otherwise this is not a id selector. Also it's always better to call these .load() events inside the .ready() jQuery event whose famous shortcut is $(function() { //execute when DOM is ready }); . In your case:
$(function(){
$(window).load(
function(){
$('#adiv').html('<p>hello world</p>');
}
);
<html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" language="javascript"></script> <script language="javascript"> $(window).load(function() { $('#adiv').html('<p>hello world</p>'); alert('done'); }); </script> </head> <body> <div id="adiv"> </div> </body> </html>
Paste this code instead ur query
It Will Work
Try $(document).ready(function()... instead of $(window).load(function()...

Okay... obviously this is because I am so new. I don't understand why this does not work. I thought this is because the argument its not inside a function but I don't really know.
<head>
<title>Documento sin título</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">
$(function(){
$("p").hide();
});
</script>
</head>
<body>
<p>hi</p>
</body>
It should look like this:
<script src="jquery.js"></script>
<script>
$(function() {
$('p').hide();
});
</script>
First you must load the external Javascript file (like jquery.js) in its own script tags. Then you include your Javascript (or jQuery for this case) in its own script tags.
Your code works!
However, you need to load the JS file first. The function to hide the p should be in its own <script> tag (different one from loading the script)
$(function() {
$("p").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<p>hi</p>
<div>world!</div>
Here is my Jquery code.Please have a look through it and do help me?
<script type="text/javascript" src="jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$("#rec").click(function() {
$("#tab1").toggle();
});
</script>
<input type="button" class="button" id="rec" value="Sample"/>
<div id="tab1">
Hello this is a sample jquery toggling function.
</div>
Just wrap your Jquery code inside $(document).ready(function(){}) as shown below :-
<script type="text/javascript">
$(document).ready(function(){
$("#rec").click(function(event) {
event.preventDefault();
$("#tab1").toggle();
});
});
</script>
Read More on $(document).ready() here.
Working Demo
It seems that there is an error while loading JQuery try this
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
Use $(document).ready(function(){}, to execute the js code when then document will be loaded or put your scripts just before the </body> tag.
I ll take a guess here. (I'm feeling lucky!) (update:seems i wasn't lucky but read this anyway it's usefull)
Your code does not work because you say "do something when the html element with id="rec" is clicked" and "do something to the html element with id="tab1""
My guess is, you have more than one html element with id="rec" and/or more than one html element with id="tab1" in your code.
id value of html elements must be unique across a webpage! If there are more than one html elements with the same id then the jquery selector doesn't know when to fire, and also browsers behavior can be unexpected. This may be the cause of internet explorer nagging.
You need to add compatibility meta just after <head> tag:
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge;chrome=1" />
I am using a script to make tables in html sortable. The script is here- http://www.kryogenix.org/code/browser/sorttable/. I want the text which sorts the html table to be clicked automatically when the i loaded. The autoclick script i am using is this-
<head>
<script LANGUAGE='javascript'>
function autoClick(){
document.getElementById('sort').click();
}
</script>
</head>
<body onload="autoClick();">
<table><tr><th><p id="sort">Click here to sort the table</p></th>...
The problem is that this is not working and i am confused that why this isnt working.
--------------------EDIT------------------
Sorry for this but actually i was typing something wrong in the body onload statement. Thus the script i was using was correct.
Where have you defined your event?
Because I see juste one function in your onload.
Below, a little example which work fine:
<html>
<head>
<script type='text/javascript'>
var init = function()
{
document.getElementById('test').addEventListener('click', function() {
alert('Auto test is ok');
}, false);
};
function autoClick(){
document.getElementById('test').click();
}
</script>
</head>
<body onload="init(); autoClick();">
<button id="test">Test</button>
</body>
</html>
It's always safer to use Jquery library. Just include the latest Jquery library on your header section of the page:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js" type="text/javascript"></script>
and this function Should solve your issue:
$("#sort").live('click');
I think you missed the class name in the table
Please add your table tag with class name called "sortable".
I have tried to set a item to read only, as you see in the code i have tried several way and can't get that to work. Can anyone help me with this?
<html>
<script>
//test.Attributes.Add("readonly","readonly")
//document.getElementById('testtt').setAttribute('readonly', 'readOnly');
// document.getElementByID('test').value=readOnly;
//document.getElementByID('test').readOnly = true;
// $("#test").attr("readonly", "readonly");
//$("#test").removeAttr("readonly");
//$('#test').attr('readonly', 'readonly');
$("#test").attr("readonly")
</script>
<body>
<input id="test" type="text" value="text" />
</body>
</html>
$('#test').attr('readonly', true);
working example : http://jsfiddle.net/FBUDt/
this should work for you:
$("#test").attr("readonly", "readonly");
remember that the DOM needs to be loaded before you try to find the element
you could use jquerys DOM-ready
$(function() {
$("#test").attr("readonly", "readonly");
});
what version of jquery are you using?
You should try wrapping your code into $('document').ready();
According to the documentation,
The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers and run other jQuery code.
So it would be:
$('document').ready(function(){
$("#test").attr("readonly", "readonly");
});
You can't refer to an element that is created later in the document. Move the script down below the form, or place it in a document.ready block. Also, you should use $.prop() in jQuery 1.6+
$(function(){
$('#test').prop('readonly', true);
});
I would go with
document.getElementById('test').setAttribute('readonly', 'readOnly');
But that is not the issue. The position of your script is where it goes wrong. You are trying to change element which does not exist.
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>testcase</title>
<link rel="stylesheet" href="stylesheet.css" type="text/css" />
</head>
<body>
<div class="some container">
<input id="test" type="text" value="text" />
</div>
<script type="text/javascript" charset="utf-8">
document.getElementById('test').setAttribute('readonly', 'readOnly');
</script>
</body>
</html>
If you place your scripts right befor the closing </body> tag , then it is executes as soon as DOM has been built.
And please. Stop using JS libraries to do the most basic things.
you are missing
$(document).ready(function() {
$('#test').attr('readonly', 'readonly');
});
sample
http://fiddle.jshell.net/Pe4J5/
I am new to javascript and jquery. I want to use $(document).ready to register some event handlers. For example, code like this, and my question is what javascript libraries do I need to refer to at the head of the page in order to use $(document).ready? Appreciate if anyone could provide me a simple easy to use sample to learn $(document).ready.
<script>$(document).ready(function()
{
// function implementation internals
});
</script>
thanks in advance,
George
All you need is the jQuery library.
http://www.jquery.com
You can either download the library and include it from your own server or you could use one of the many CDN's which provide the library. For instance:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
// do something useful
});
</script>
Google keeps copies of a bunch of libraries on their servers, which are pretty reliable.
Just add the following to your <head> section, and place your snippet somewhere below.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
In summary,
Put the <script> tag provided by sje397 in the <head> section of the page, which provides the only library you need... jQuery.
(Alternatively: <script src="http://code.jquery.com/jquery-1.4.4.js" type="text/javascript"></script>)
Read http://docs.jquery.com/Tutorials:How_jQuery_Works
And you should be good to go.

<script type="text/javascript">
(function($) {
$(document).ready(function() {
$('#someElement').bind('click', function(event) {
// event.preventDefault(); // you might want to do this if your event handler has a default action associated with it (e.g. a link that gets clicked with an href)
// do stuff on your event (change click to whatever you need)
});
});
})(jQuery);
