Create an array from a string

I have a webpage where a user can select multiple items from a jquery list.

Based on the item(s) selected I need to add each item into the database.

When someone selects one item the value returned to my Javascript is similar to "4~2"

The value 4 would be used in my example for one column named "skill_id" in the database and the value 2 would be used for another column called "category_id" in the same row.

When someone selects two items it is comma-delimited and similar to "4~2,6~7" and so on if they select more than 2.

I'm thinking I need to do a for loop with an array or a jquery.each() function but not certain how the best way to approach this is.

Here is one way you could extract the skill_id and category_id:

  $.each("4~2,6~7".split(','), function(index, value) {
      var nums = value.split("~");
      var skill_id = nums[0];
      var category_id = nums[1];
  });

What you're looking for is the split() method.

"4~2,6~7".split(',') // ['4~2', '6~7']
