jquery change array to string

Question

using this little jquery i am able to save the data-id of the clicked list-element in an input-hidden-field:

(Important: Only one data-id can be saved in this input-hidden-field, if you click next element, this hidden-field gets updated.)

$(document).ready(function(){
    $('.ui-selectable :not([data-id=""])').click(function() {
        $('.ui-selectable .selected:not([data-id=""])').removeClass('selected');
        $(this).toggleClass('selected');
        $(this).parent().trigger('update');
    });

    $('.ui-selectable').on('update', function() {
        data = [];
        $(':not([data-id=""]).selected', this).each(function() {
            data.push( $(this).data('id') );
        });
    });
});

For now its saved in an array as you can see in:

data = [];

But i need to save it in a string, anybody could help with it?

Maybe call JSON.stringify on the array?

You can change that array into a string by using JSON.stringify,

Try this,

JSON.stringify(data);

which line do i have to put it? after i declared the array?

@user3080627 This will convert the array data into a string. So you can call it after filling your array.

Some browsers don't support the JSON object. For more browser compatibility, you can just use the Array object's native toString() method. That is data.toString().

The join method will give you a comma separated string of your array.

This is a bad way to serialize arrays. If any strings within the array had a comma, you'd run into problems deserializing the string later. This is, of course, not always a problem if you know what type of data is in your array, but perhaps not the best habit to get into.
