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

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]);
}
