jquery data() - how to read out all key/value pairs?

Question

I'm trying to understand a jquery script which stores an object using jquery data().

Is there an easy way to retrieve all information stored? Especially since I don't know all of the keys that have been used.

Thanks for help!

If you call .data() with no arguments, it returns what you want.

var allData = $('some-element-selector').data();
for (var k in allData)
{
    if (allData.hasOwnProperty(k))
    {
        console.log(k + ':' + allData[k]);
    }
}

just calling data() returns [object Object]. Trying your function. – frequent Oct 12 '11 at 10:54
That's why you have to iterate through it to get the values – Pierre de LESPINAY Oct 12 '11 at 10:55
@frequent correction: calling `.data().toString()` returns `'[object Object]`. Start using a real debugger instead of `alert()`. – Matt Ball Oct 12 '11 at 11:01
@Matt: I used to alert()... console.log is more convenient although I have not quite figured my way around Firebug... Thx! – frequent Oct 12 '11 at 11:04
