Javascript problem

[linksor.com]

Hi,

I know 5.4 is not supported but some users reported me that there is an error in Javascript (JSON).

link: json.js:91

Does anybody know what that means ?

May I download new version JSON or copy it from new IU ?

This error causing an issue that it is impossible to submit page into directory and browser must be closed and reopen ... sometimes user must wait a little time and refresh a form/page

[rman]

... in our site
Any news about jason.js ?

thanks a lot

[linksor.com]

no news.

it seems that where there are a lot of users online at one moment the json is not working correctly. On my other sites where I dont have many users online (up to 20-30) there is no such problem.

Problem exitsts only on 5.4.x

[rman]

please if you find a solution post it here!
Thanks a lot

The json.js script is originally from here: JSON

which package ? JSON for PHP - could U be more specific please ?

[linksor.com]

never mind - I have found json.js and testing it currently - seems to be better (no such errors) but I must make a test on a bigger site.

I will post some news after I make some tests

OK seems that this version of JSON.JS working. Just copy the code and paste it into JSON.JS file. With the Old one please make a backup.

    This file adds these methods to JavaScript:
        array.toJSONString()
        boolean.toJSONString()
        date.toJSONString()
        number.toJSONString()
        object.toJSONString()
        string.toJSONString()
            These method produces a JSON text from a JavaScript value.
            It must not contain any cyclical references. Illegal values
            will be excluded.
            The default conversion for dates is to an ISO string. You can
            add a toJSONString method to any date object to get a different
            representation.
        string.parseJSON()
            This method parses a JSON text to produce an object or
            array. It can throw a SyntaxError exception.
    It is expected that these methods will formally become part of the
    JavaScript Programming Language in the Fourth Edition of the
    ECMAScript standard in 2007.
