$.post(document.location) doesn't work anymore since 1.4.3 on Firefox and Chrome

[xaviermd@…]

I created a veryu complex javascript onto jquery 1.4 and it was (nearly) perfectly working with 1.4.2 (I mean : it consumes a lot of RAM to make browser crashes very frequently).

Since 1.4.3 and 1.4.4 , $.post() command goes to javascript halts :

Firefox 3.6.12: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: ​https://myservice/interface/stage1.js :: anonymous :: line 5767" data: no]

the calling offender : $.post(document.location,{action:'fresh' , ordre:"{\"0\":[\"fonctions\",\"perso_message\",\"commandes\"],\"1\":[\"raccourcis\",\"suggestions\"]}"},function(datas){ return something; },'json');

the lines 5762→ 5767 are :

ajax: function( origSettings ) {

var s = jQuery.extend(true, {}, jQuery.ajaxSettings, origSettings),

jsonp, status, data, type = s.type.toUpperCase(), noContent = rnoContent.test(type);

console.log(s.url); console.log(rhash);

s.url = s.url.replace( rhash, "" );

s.url : Object { constructor={...}, href="​https://myservice.../", more...} rhash : /#.*$/

Chrome 6:

s.url : Object Location { assign: function () { [native code] } hash: "#.*$/" host: "myservice..." hostname: "myservice..." href: "​https://myservice.../#.*$/" pathname: "/" port: "" protocol: "https:" reload: function () { [native code] } replace: function () { [native code] } search: "" toString: function toString() { [native code] } valueOf: function valueOf() { [native code] } proto: Location

} rhash : /#.*$/

Failed to load resource: the server responded with a status of 404 (Not Found) /undefined

Personnal note :

I believe the problem came from document.location which was not seen as an string anymore Firefox doesn't like regex on objects, Chrome respond to the .replace by "undefined"

Please include a valid complete test case on jsFiddle.net that reproduces the issue you are experiencing so that we can investigate further.

I don't understand jsFiddle. Perhaps ​http://jsfiddle.net/KLrer/4/ ?

$.post(document.location,{},function(data){alert(data);},'html');

GRAH. Askimet is eating my message.

​http://jsfiddle.net/KLrer/4/ ?

$.post( document.location, {} ,function(data) {alert(data);},'html');

jQuery 1.4.3+ : no responses, silently fails (in fact, «uncaught exception»)

$.post( document.location.href, {} ,function(data) {alert(data);},'html');

jQuery 1.4.3+ : alert responds. works

Landed.

Move fixed tickets to appropriate milestone

Enhances ajaxSetup so that it can take an optional target option, in which case target will be updated instead of ajaxSettings. That way, fields that shouldn't be deep extended can be listed and dealt with in one place. jQuery.ajax now makes use of ajaxSetup with target to create its internal settings object. Fixes #7531 in IE9RC.
