Can I wrap a javascript event in a jQuery event?
I开发者_JS百科 have this code:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$('a.one').click(function(event){
event.preventDefault();
});
});
function test(event){
event.preventDefault();
}
</script>
<style type="text/css">
a.test { font-weight: bold; }
body { font-family:sans-serif; background-color:#AAAAAA;}
</style>
</head>
<body>
<a class="one" href="http://jquery.com/">jQuery</a>
<br/>
<a class="two" href="http://stackoverflow.com/" onclick='test(event)'>stack overflow</a>
</body>
</html>
The test-function does not work as it stands now, since a regular javascript event doesn't support the jQuery event preventDefault-function. Is there some way to wrap a regular javascript event in a jQuery event so that I can use e.g. preventDefault?
Try this:
function test(e) {
$.Event(e).preventDefault();
}
Event object
I've found the best way to wrap a native event in a jQuery event is with fix:
event = $.event.fix(event);
Please note, this function is not part of the public API (although it really should be).
I think it may be the fact that you're passing event in with onclick='test(event)'. I think onclick='test' is enough. I could be wrong though.
Yes (see Darin's answer). You could also work around IE's lack of preventDefault instead (which is essentially what jQuery is doing):
if ('preventDefault' in event)
e.preventDefault();
else
e.returnValue= false;
When you just want to execute the javascript - and not redirect - when clicking the href use "return false" in your click function. For example:
$(function(){
$('a.one').click(function(event){
var condition = confirm('Do you want to redirect to ...?');
return condition == true;
});
});
If you never want the link to redirect use 'javascript:void(0);' as href attribute, all browsers will still render it as a link instead of an anchor (some IE version do this).
