I have page which contains jQuery code:
$('#tstButton').live('click',function(){
alert();
});
And I load this page from ajax call.
When I load the page multiple times, each time it loads the script and stores to cache.
Say when I make ajax call three times. and click $('#tstButton') once, then it will alert 3 time.
I have used:
cache:false
in ajax call. But still its not clearing cache.
How can I clear these javascript codes from cache?
You can unbind the event first before binding using die() if you're using jQuery < v1.7.2.
$('#tstButton').die('click').live('click', function() {
alert();
});
If you're using jQuery v > 1.7.2
You can use on and off:
$('#tstButton').off('click').on('click', function() {
alert();
});
You can OFF your previously binded click using jquery OFF function.
$('#tstButton').off("click").on('click',function(){
alert();
});
die() should be used regarding event bound using live() but that's just bad workaround regarding event bound multiple timesIn my opinion, it is not a good solution to bind \ unbind event every time when you have dynamically loaded page.
You can use event delegation and bind it only once.
Execute this once on page load and it will properly work on any dynamically added elements:
$(document).on('click', '#tstButton', function() {
alert();
});
document can be replaced with more precise non-updating container which stores this button.
Here is a working JS Fiddle Demo
bind it only once Ya, that's how it should be done
