Question

I am trying to achieve something here. Once I click a link, the value of a hidden element specified for that link will be set to 1 (0 by default). This works fine.

Next step, I am looping through all hidden elements to see which ones are set to 1. If it is set to 1, I add its ID to a variable. The next one that is set to 1, its ID needs to be put in the same variable behind it.

So the variable with the IDs should look like: hidden1/hidden2/hidden3

It is hard to explain, but here I reconstructed it:

Once I click the the SUBMIT button, it looks up if it is 1 or 0 just fine. Then it loops through the hidden elements. It recongizes that the element is either set to 1 or 0. After that, it goes wrong.

Answer 1

Remove the var statement before test_total inside the callbacks and you will be fine! You are re-declaring the test_total variable within the each-callback scope.

So this part is changed (I truncated the comment for readability):

            if (test_total == "EMPTY") {
                test_total = $(this).attr("id") + "/SEPERATOR/";
            // In case the variable [...]
            } else {
                test_total = test_total + $(this).attr("id") + "/SEPERATOR/";
            }
