js generates random numbers within a certain range

You can use the random() method, which returns a random number between 0 ~ 1.

The specific code is as follows:

//生成最小min到最大max的随机数
function random(min,max){
        if(min > max){
            var ls = min;
            min = max;
            max = ls;
        }
        return Math.floor(Math.random() * (max-min+1) ) + min;
    }
