I'm experiencing a rather bizarre behaviour in JQuery.
I'm dynamically loading a series of scripts using this code:
for (var i=0; i<requiredScripts.length; i++)
{
$.ajax({
url: baseURL+"js/"+requiredScripts[i],
async: false,
dataType: 'script',
success: checkLoaded
});
}
The checkLoaded
function just increments a counter, so that when all of the scripts have been loaded it executes certain func开发者_开发百科tions.
Everything was working fine until I uploaded a newer version of one of the loaded scripts. JQuery seems to continue loading the old one. I tried refreshing (and force refreshing) the page in vain...
So I disabled the cache (from the WebDeveloper toolbar) and now the script magically loads. But when I reenabled the cache the old script came back...
I went as far as deleting the file from the server, and that did not do anything! (unless I disable the cache, that is).
I'm sure I'm just missing something really simple, but I could not figure it out.
Thanks in advance to anyone who can help.
EDIT: just to clarify, I do want the file to be cached. What I don't understand is why a force refresh of the page does not result in getting the new script.
Also, note that this only happens if I load the files with JQuery, if I add them manually in the HTML a force refresh loads the new page.
EDIT #2: solved by deleting the cache from FF. Still, don't understand why a CTRL+SHIFT+R did not do the trick...
$.ajax has a cache option that does the same thing as mck89's answer but is a little neater:
$.ajax({
url : 'example.com',
cache : false,
....
});
You can simply use the classic caching disabling method.
var cd=+new Date();
for (var i=0; i<requiredScripts.length; i++)
{
$.ajax({
url: baseURL+"js/"+requiredScripts[i]+"?"+cd,
async: false,
dataType: 'script',
success: checkLoaded
});
}
In this way the script url is always different and you are sure that its content is not cached.
Tell apache to sent no-cache headers for your JS files:
<Directory "/path/to/baseURL/js">
Header Set Cache-Control "max-age=0, no-store"
</Directory>
