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: http://jsfiddle.net/GQ83Y/ FYI, depending what you are attempting to do, you shouldn't convert it to number, keep it as string — A. Wolff, Nov 25 '13 at 13:46

@A.Wolff It's not converted to a number anywhere in the code above… — feeela, Nov 25 '13 at 13:52
@feeela Maybe `$().data` auto-converts the string to a number, in some browser or version of jQuery? I agree that I couldn't reproduce that behavior, but if that is what's happening, the OP could get around this by adding a non-numeric character to the start or end of the value, and then stripping it after retrieval. — apsillers, Nov 25 '13 at 13:55
@apsillers ya, seems fair but then that means .data() behaviour differs from browser to browser as .data() doesn't convert string to number in chrome, as i can test it — A. Wolff, Nov 25 '13 at 13:59
@Johan, that doesnt work since the first string I get is allready different. Im dont receive the correct number so I cant do anything with it :-) — Arjen, Nov 25 '13 at 14:02
chrome,latest. Solved it by adding |123456....0| and stripping it later :-) Thx for the suggestion !! — Arjen, Nov 25 '13 at 14:03
@user1416256 try using: `$(this).attr('data-number');` should fix string beeing converted — A. Wolff, Nov 25 '13 at 14:03

Use this

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

Bcoz

$(this).data('number')

is returning number not string
