function getRandomInt(min, max) { min = Math.ceil(min); max = Math.floor(max); return Math.floor(Math.random() * (max - min)) + min; //不含最大值,含最小值 } 虽然我们可以这样去取整数,但是时候之后我们会发现,能取得的量的最后一个值,没办法随机到,这是因为我们random本质上范围还是小...

In JavaScript, we can generate random numbers using the Math.random() function. Unfortunately, this function only generates floating-point numbers between 0 and 1.In my experience, it's much more common to need a random integer within a certain range. For example, a random number between 10...

In this tutorial, we will learn about the JavaScript Math.random() function with the help of examples. In this article, you will learn about the Math.random() function with the help of examples.
The range of characters 0123456789abcdefgh would be the octadecimal digits (digits in base 18), so you could do this: function getCharacter() { return Math.floor(Math.random() * 18).toString(18); } Now do it 14-16 times: for( var str="", i=0, l=14+Math.floor(Math.random(...
