How can I return a random value from an array?

Question

I\'m using the jQuery validate plugin, and would like to return a random value on success.

Right now I\'m trying to use:

     var success_message =          


        

Answer 1

You can store the messages array and calculate the message to show as you go, like this:

var messages = ["Good!", "Great!", "Awesome!", "Super!", "Nice!"];
function getMessage() {
   return messages[Math.floor(Math.random() * messages.length)];
}

Give it a try here, then just call getMessage in your .text() call, like this:

label.addClass("valid").text(getMessage());

Answer 2

function sucess() {
 message = ["Good!","Awesome!","Super!","Nice!","Great!"];
 return message[Math.floor(Math.random() * message.length)];
}

 $(document).ready(function(){
     var validator = $(".contactform").validate({ ...
              success: function(label) {
    label.addClass("valid").text(success());
 }
      }); //end form validate code
         });

Answer 3

We can add Method to Array.

Array.prototype.getRandomVal = function(){
    return this[Math.floor(Math.random()*this.length)];
};

messages.getRandomVal();
