Converting string to number in javascript/jQuery

Question

Been trying to convert the following to number:

    1


        

Answer 1

You can adding a + before the string without using parseInt and parseFloat and radix, Simply

sample:

var votevalue = +$('button').data('votevalue');

alert(typeof(votevalue));

Answer 2

var string = 123 (is string),

parseInt(parameter is string);

var string = '123';

var int= parseInt(string );

console.log(int);  //Output will be 123.

Answer 3

You should just use "+" before $(this). That's going to convert the string to number, so:

var votevalue = +$(this).data('votevalue');

Oh and I recommend to use closest() method just in case :)

var votevalue = +$(this).closest('.btn-group').data('votevalue');
