JavaScript总和值 [英] Javascript Sum Values

问题描述

我需要对javascript中的几个值求和.我已经尝试过使用以下代码

I need to sum several values in javascript. I've tried by using following code

var a = 2;
var b = 5;
c = a+b;

但是，除了计算a和b的值外，输出(c)仅合并了这两个值.所以给出的输出是:

But, instead of calculating the values of a and b, the output (c) only combine those two values. So the output given is :

c = 25

我相信你们可以在这方面帮助我.谢谢.问候安达.

I believe you guys can help me easily about this. Thx before. Regard Andha.

推荐答案

请确保值是数字，否则它们将连续而不是求和.

Make sure the values are numbers, otherwise they will concat instead of suming.

a = parseInt(a, 10); // a is now int
