Question

I am essentially adding radio-buttons functionality to buttons with the class “tagbutton”. There is a flaw with my code, because _this is never _last…

  taguid = "";
    _last = "";
    $('.tagbutton').live('click', function() {

    _this = $(this);
    if(_last) {
        //There was a last object
        if(_last == _this) { // The last object was the current object
            alert('deactiveate for this obj');
        } else { // The last object was not the current object
            alert('deactivate last, activate this');
        }
    } else {
        alert('first object activated');
        var taguid = $(this).prev().attr('data-uid');
        alert(taguid);
        _last = $(this);
    }

    });

It’s because the objects’ references aren’t the same. A simpler way might be to activate the clicked one, then deactivate the last one. It’ll have the same effect:

var taguid = "";
var _last;
$('.tagbutton').live('click', function() {
if(_last) {
    // There was a last object
    // Activate this
    // Deactivate last
} else {
    alert('first object activated');
    var taguid = $(this).prev().attr('data-uid');
    alert(taguid);
    _last = $(this);
}

});
