Javascript array index is var

Question

I am working on a site with dynamically generated jquery tabs. Each tab has an identifier.

For my script, I need to know how many times the user has visited the tab.

To record the number of clicks that I thought of creating an array as follows:

var i  = new Array(my_tab_id);
(...)
i[my_tab_id] = 0;

Where my_tab_id changes dynamically depending on the tab we are in. Unfortunately, it does not look like the value of my_tab_id has been translated into an array. I don’t have me [5] = 0, I [6] = 0, etc., But rather I [my_tab_id], which is nothing more than just var.

Any tips? Thank!

This will allow you to save the number of clicks on each tab using the function .data()in jQuery every time the tab is clicked.

$('#example').bind('tabsselect', function(event, ui) {
    var count = parseInt(ui.tab.data("clickCount"));
    if (isNaN(count)) count = 0;
    count++;
    ui.tab.data("clickCount", count);
});
