It's the same in javascript :)

它在 javascript 中是一样的 :)

var res = (x > y) ? x : y;

回答by CL22

var x = 2;
var y = 3;
var res = (x > y)? x: y;

Although perhaps the following would be better:

虽然也许以下会更好:

var res = Math.max(x, y);

It is the same in javascript:

在 javascript 中也是一样的:

res = (y < x) ? x : y;or res = (x > y) ? x : y;

res = (y < x) ? x : y;或者 res = (x > y) ? x : y;

回答by Majid Fouladpour

The same. It is called ternary:

相同。它被称为三元:

var x = 10, y = 50, res = 0; 
res = (x > y) ? x : y; 
alert(res);

回答by helle

Here you are: var res = x>y?x:y;

这个给你: var res = x>y?x:y;
