Split comma-separated input box values into array in jquery, and loop through it

Question

I have a hidden input box from which I'm retrieving the comma-separated text value (e.g. 'apple,banana,jam') using:

var searchTerms = $("#searchKeywords").val(); 

I want to split the values up into an array, and then loop through the array.

Answer 1

var array = $('#searchKeywords').val().split(","); 

then

$.each(array,function(i){    alert(array[i]); }); 

OR

for (i=0;i<array.length;i++){      alert(array[i]); } 

OR

for(var index = 0; index < array.length; index++) {      console.log(array[index]); } 

Answer 2

var array = searchTerms.split(",");  for (var i in array){      alert(array[i]); }
