A Simple Method to Add Whether a String Contains a String to Array in JS

The JS Array type itself does not have a method to check if it contains a string, the following code implements this function, those who need it can take a look:

Array.prototype.contains = function(v){
  var b = false;
  for(var i=0;i<this.length;i++{
    if(this[i] == v){
      b = true;
      break;
    }
  }
  return b;
};

That's all for the simple method of adding a string to an array in JS brought to you by the editor. Hope everyone will support and cheer for the tutorial~
