Question

Hi I am working on this piece of code for a shopping cart

$('.addtoCart').click(function() {

    //get button id      
    var cartID = $(this).attr("id"); 

    //get check box id   
    var checkBoxID = $('input.cartLevelChecked:checked').attr("id");

    //get parent id
    var levelListID = $(this).closest('li').attr("id");

    if(('#'+cartID && '#'+checkBoxID).parent('#'+levelListID)){
        $(".selectPlan").show();
    }

    //alert(/*cartID + checkBoxID +*/ levelListID);
});

Basically I’m checking to see if the check-box the user checked and button they clicked on belongs to the same parent then show a div

any help would be greatly appreciated. thanks

You need to compare levelListID, which you correctly queried, to the id of the checkbox’s closest li parent, which you should query the same way:

if (levelListID === $('#' + checkBoxID).closest('li').attr('id')) {
    ...
}
