String format in javascript

Question

I'd like to format a number and remove starting 0s from it. e.g.:
001 => 1

10 => 10

Actually, I have a jQuery method which does the following:

  $('#myelement').text($('#myElement').text()+1);

When the element's text is 0, the function makes it 01, How can I make it to show 1 using jQuery or javascript?

Thanks.

what you need:

parseInt($('#myElement').text(), 10) + 1;

what you're asking for:

($('#myElement').text()+1).replace(/^0+/, '');

Hence the "what you're asking for" predicate. The original question said "I'd like to format a string..."

toFixed returns a string too, but it is aware of rounding rules. For example.

toFixed is on numbers, not strings. If you literally want to remove leading zeros from a string, my answer is correct

I see your point now, please edit your answer a little so I can upvote it.

You can use parseInt("0010", 10).toString(). Ignore toString() if you need the int only.

Assuming you want to increment the value, convert the current text in to a number using unary +:

$('#myelement').text(function(i, v){
    return +v + 1;
});
