How do I select random values from an array in Javascript or Jquery? [duplicate]

Answer 1

You can try something like this:

Logic:

• Create a temp array so it does not replace original value.
• Calculate random number and use % array.length to find correct index.
• Use array.splice(index, 1) to remove the element from temp array, so that it will not repeat.

var arrayNum = ['One', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine'];  

function getRandomValues(arr, count){
  var result = [];
  var _tmp = arr.slice();
  for(var i = 0; i
