Question

I have this code:

            $('.counter_d').mouseover(function() {
                   $('#description').html('Counter');
             });
            $('.selector_d').mouseover(function() {
                   $('#description').html('Selector');
             });
             $('.date_d').mouseover(function() {
                   $('#description').html('Date');
             });

and several more, but I think the file could be smaller and even reusable using loops, but I’m not able to bind the description (HTML method) with the selector.

I want to use something like this:

              var selectors=['.counter_d','.selector_d','.date_d'];
              var description=['Counter', 'Selector', 'Date'];


              for(var i=0; i<selectors.length; i++)
                 $(selectors[i]).mouseover(function() {
                   $('#description').html(description[i]);
                 });

Any help? Thanks

Answer 1

var selectors = {
    '.counter_d': 'Counter',
    '.selector_d': 'Selector',
    '.date_d': 'Date'
};


$.each(selectors, function (key, value) {
    $(key).mouseover(function () {
        $("#description").html(value);
    });
});
