A Simple Method of Generating Random Numbers Between N and M by JavaScript

In this paper, an example is given to describe the simple method of generating random numbers between N and M by JavaScript. Share it for your reference, as follows:

getRandom. js:

/**

// Get 1 Random number, in max,min Between 
//max  Need to be greater than  min
// If you enter  10 Is generated  0~9  Number of 
// If you enter  10,4 Is generated  4~9  Number of 
// If you enter  10,40 Is returned  false
function getRandom(max,min){
  var rand=false;
  rand=Math.floor(Math.random()*max);
  if(!(min==undefined) && (max>=min)){
    rand=Math.floor(Math.random()*(max-min)+min);
  }else if(max<min){
    return false;
  }
  return rand;
}
