Ajax/cache: change the separator

in Using jQuery • 12 years ago

Hallo,

if you don't wont to cache an ajax-request (cache: false;), ajax() appends something like
&_=1278682998056 to the url.

Is it possible to change the separator from '&' to ';'? My php-configuration don't really accept '&'.

thanx

Hello hasenfote,

While I am unsure on your specific problem and whether the actual solution is to replace the '&', you could attempt to tap into the ajax request just before the send by specifying a beforeSend callback:

$.ajax({

beforeSend : function(xhr){

xhr.url = xhr.url.replace(/&_=/,';_='); //modify xhr.url here with changes you want.

}

});

You'll need to be careful that a false positive is not found with a replacement such as the one demonstrated above.

Cheers,

awirick

Hello awirick,

thank you for your quick reaction. I guess your workaround should mostly work, but as you mentioned by yourself it changes all '&_='. Even parts of the values (o.k. '&_=' should be a rarely used string).

Today I've looked into the sourcecode of jQuery-Core 1.4.2 and find out that the separator is hardcoded as a string "&". If it would be possible to change it anyway, it must be coded as a variable.

The code is mostly something like this (to decide wich character should be appended):

rquery.test(s.url) ? "&" : "?"

I think it should be possible to give jQuery a global parameter for handling GET-separators or a local parameter for the ajax()-methode (as part of the options-object).

Unfortunately I'm not familiar enough with the sourcecode to change it by myself (without damaging anything else). Probably it will be changed in future releases. Because the W3C recommends using ';' instead of '&' as a separator. Untill that I have to use your workaround.

Thanx & CU
