Question

I am passing some values out of a form into a function so it is ready for database insertion.
The function theoretically works fine. However, it misses a unique value that puts me in trouble afterward.
I’m trying to generate a unique ID based on the data that is submitted to the database.
I want to generate the ID like this:

var mystringId = prodID+'{‘+selectId+’}’+selectedOptionValue;

Should output for example: 20{100}3{200}6.
In my sample it generates above the following:

20{100}3

20{200}6

because of the each();

$("#submitme").live('click', function() {
//var mystringId = prodID;
    $('select').each(function() {
        var addedOn = new Date();
        var selectName= $(this).attr("name");        
        var selectId= $(this).attr("id");
        var selectedOption = $(this).find('option:selected');
        var selectedOptionValue = selectedOption.val();
        var selectedOptionText = selectedOption.text();

        var mystringId = prodID+'{'+selectId+'}'+selectedOptionValue;

        db.transaction(function(tx) {
        tx.executeSql('INSERT INTO xxxxx mystringId');

        });

    });
    $.mobile.changePage( "#cart", { transition: "slideup"} );
    });

From what I can gather from your question, you can simply do a each loop before your current code to generate the mystringId in the format your looking for to use inside your code.

Code

$("#submitme").live('click', function() {
    var mystringId = prodID;

    $('select').each(function() {
        var selectId= $(this).attr("id");
        var selectedOption = $(this).find('option:selected');
        var selectedOptionValue = selectedOption.val();

        mystringId += '{' + selectId + '}' + selectedOptionValue;
    });

    $('select').each(function() {
        var addedOn = new Date();
        var selectName= $(this).attr("name");
        var selectId= $(this).attr("id");
        var selectedOption = $(this).find('option:selected');
        var selectedOptionValue = selectedOption.val();
        var selectedOptionText = selectedOption.text();

        db.transaction(function(tx) {
            tx.executeSql('INSERT INTO xxxxx mystringId');
        });
    });

    $.mobile.changePage( "#cart", { transition: "slideup"} );
});

Results

The results would be mystringId starting off with the value of prodID mystringId = 20

The first iteration of the loop would append {100}3 resulting in mystringId = 20{100}3

The second iteration of the loop would append {200}6 resulting in mystringId = 20{100}3{100}6
