    Exclamation Browser 7.3 crashes with jQuery Mobile

    Hi,
    it looks like the Browser 7.3 has some Problems with jQuery Mobile (http://jquerymobile.com/)
    The Browser crashes if it opens pages which use jQuery for mobile devices.
    Tested with Nokia E72-1.
    Try it yourself:
    http://jquerymobile.com/demos/1.0/

    Tested userAgent was:
    --------------------------
    Mozilla/5.0 (SymbianOS/9.3; Series60/3.2 NokiaE72-1/073.001; Profile/MIDP-2.1 Configuration/CLDC-1.1)
    AppleWebKit/533.4 (KHTML, like Gecko)
    NokiaBrowser/7.3.1.26
    Mobile Safari/533.4

    Can anyone confirm this?

    Regards,
    Bernd

    Re: Browser 7.3 crashes with jQuery Mobile

    Hi Bernd,

    Is there some specific test that crashes the E72?
    I visited that site with N8 that also has Browser 7.3 and it was working fine.

    Re: Browser 7.3 crashes with jQuery Mobile

    Hi Ilkka,
    no specific tests, I just tried to call that page and the Browser crashes.

    I ran into this problem because we use jQuery for our web pages and now also use jQuery Mobile 1.0 for web pages for mobile devices.
    My Nokia Browser crashes always immediately while calling jQuery Mobile pages. First I thought about a problem with our
    implementation, but then I called pages using jQuery Mobile Framework and they all crashed the Browser immediately.

    I also tested with:
    Nokia E72-1 and Opera 10 Mobile - runs OK
    Apple IPhone 4 - runs OK
    Apple IPad2 - runs OK
    Samsung Galaxy Smartphone - runs OK
    Samsung Galaxy Tab - runs OK

    Very strange.
    Currently I have no idea how to locate the problem.
    Is it the jQuery Mobile Framework or really the Nokia Browser 7.3 on my E72-1 ?

    OK, just played with my E72-1 an have some further information.
    - with setting Java/ECMA-Script disabled the page http://jquerymobile.com/demos/1.0/ loads without problems.
    - then enabling Java/ECMA-Script and reloading the page --> crash!

    Whats with the option Java/ECMA-Script errors "generate protocol", will that be a help?
    And where will the protocol be located?

    Regards,
    Bernd

    Re: Browser 7.3 crashes with jQuery Mobile

    And here is there answer from Nokia to this problem:

    > Hi,
    >
    > We verified the issue with the browser team.
    > Unfortunately this is not something that we can fix for the E72 because of memory limitations.
    >
    > Best regards,
    > xxxxxx
    > Nokia Developer

    If I understand this right, the jQuery Mobile Javascript is to large to fit into memory (or not...) ?

    Whatever, it would be great to know the limitations by number and device, if there are any, don't you?
    - which devices are effected (E72, ....)
    - which limitations
    - which Browser versions

    Regards
    Bernd

    Hi,

    Finally got E72 and tested this myself - it crashed. Luckily you got the answer already from the somebody else.
    If this is a memory issue following devices could be worth testing:
