If I load some content with ajax (jQuery) which has a script tag in it, jQuery 1.5 adds the timestamp to the script tag src url. See example bellow.
Example: content what I load with ajax:
<div>text1</div>
<script type="text/javascript" src="/js/abc-xyz.js?r=1.1"></script>
This is the src url from where it loads the script code after I insert the previous content to the page:
.../js/abc-xyz.js?r=1.1&_=1297892228466
Does anybody knows why this happening? It happens only with jQuery 1.5. It doesn't happen with jQuery 1.4.4.
Code Example:
$.ajax({
url: content.html,
type: 'GET',
data: someDataObject,
success: function(data) {
// some code here
},
error: function(data) {
// some code here
}
});
Thanks.

Cant think of any other reason atm. But this should not break any functionality. – Michael Commented Feb 16, 2011 at 21:54

Reset to default 10See bellow the answer what I got back from jQuery team. Ticket #8298: http://bugs.jquery.com/ticket/8298
Answer:
After checking your report and your code samples I come to the conclusion that this isn't a bug. I also made this test case jQuery 1.4+ (until 1.5) had a bug which caused the cache option not to default to false for script requests. This bug (see #7578) has been fixed in 1.5 . Now what you might know or not know is, that jQuery does special-handle script tags when doing DOM manipulations (to prevent certain errors in IE). It filters them out and requests them via ajax. This explains why even a "normal" inline script tag suddenly is requested with additional url parameters. There are ways to work around this if it has unwanted side effects for you.
use
$.ajaxSetup({ cache: true })when appropriateuse a prefilter for script requests and e.g. check for urls where you don't want the random parameter to be added and set cache: true in the prefilter for those
in e.g. the success call back handle the script tags yourself by doing something along these..
..lines:
var elems = $(htmlwithscripttags);
elems.filter("script") //now do whatever with the scripts
elems.filter(":not(script)").appendTo("body"); //e.g.
Michael is correct in his comment, and if you want to disable it, use:
cache: true in the ajax request. To enable, use cache: false (which I believe is default).
To disable the timestamp:
$.ajax({
url: content.html,
cache: true,
type: 'GET',
data: someDataObject,
success: function(data) {
// some code here
},
error: function(data) {
// some code here
}
});
