large number in html5 data element

Question

How do I get the correct number from this data url ?

<a href="#" id="number" data-number="106454129446370134989">click me</a>

$(function(){
$('#number').click(function(e){
        e.preventDefault();
        var number= $(this).data('number');
        alert(number);
            //106454129446370130000
})

edit: seems .data() has some strange behaviour. Solved it by adding || around the number and stripping it later.

edit2: problem was with jquery 1.7 branch. 1.9 works :-)

Which browser? Works here using chrome: jsfiddle.net/GQ83Y FYI, depending what you are attempting to do, you shouldn't convert it to number, keep it as string — A. Wolff

@A.Wolff It's not converted to a number anywhere in the code above… — feeela

@feeela Maybe $().data auto-converts the string to a number, in some browser or version of jQuery? I agree that I couldn't reproduce that behavior, but if that is what's happening, the OP could get around this by adding a non-numeric character to the start or end of the value, and then stripping it after retrieval. — apsillers

Use this

$(this).attr('data-number')

Bcoz

$(this).data('number')

is returning number not string
