在Javascript中将多个变量分配给相同的值 [英] assign multiple variables to the same value in Javascript

问题描述

我在JavaScript文件中初始化了全局范围内的几个变量：

I have initialized several variables in the global scope in a JavaScript file:

var moveUp, moveDown, moveLeft, moveRight;
var mouseDown, touchDown;

我需要将所有这些变量设置为false，这是我目前的代码：

I need to set all of these variables to false, this is the code I currently have:

moveUp    = false;
moveDown  = false;
moveLeft  = false;
moveRight = false
mouseDown = false;
touchDown = false;

有没有办法可以将所有这些变量设置为一行代码中的相同值，或者是我目前有最好的方法来执行此操作的代码

Is there any way that I can set all of these variables to the same value in one line of code, or is the code I currently have the best way to do this

推荐答案

没有什么可以阻止你做

moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

检查此示例

var a, b, c;
a = b = c = 10;
console.log(a + b + c)
