What's wrong with this jQuery example?
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>
<开发者_如何学运维;/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()...
加载中,请稍侯......
