javascript - 如何使用jquery对货币格式的数字求和

Answer 1

The code in your question is invalid javascript. You can't have a , inside a numeric literal. You have to store it as a string, then parse it manually:

var number1 = '12,000.00';
var number2 = '12,000.00';

function parseCurrency( num ) {
    return parseFloat( num.replace( /,/g, '') );
}

alert( parseCurrency(number1) + parseCurrency(number2) );

Answer 2

This won't work. Use accounting.js's unformat function to parse 12,000 as a string instead.
