How to conduct arithmetic operations in JQuery?

Question

var price     = $(\'#addprice\').val();
var pass      = $(\'#pass\').val();
var total     = $(\'#totalprice\').attr(\'value\')
var left      = $(\'#leftquota\').attr         


        

Answer 1

use parseFloat, parseInt, or just place a + before string, if you sure it contains a number:

var text = "123.456";
var number = +text; // now 'number' is Number, and not String

Also something tells me that this should work faster than parseInt or parseFloat.

Another way to use Number object:

var text = "123.456";
var number = Number(text);

But this is the slowest way.
