Question

I’m using the jQuery maphighlight plugin with a map of the U.S.

I have several states that are too small to put their abbreviations on them, so I have to put them to the side.

What I have done already is that when the user hovers on an abbreviation, the corresponding state is highlighted. That’s working fine.

The “problem” I have is that, although the code works, it looks too repetitive to me, I’ve tried to simplify/optimize it, but the error I get is that all abbreviations highlight one single state and not the corresponding one.

Here’s the code I have so far:

$(function() {
    $('.map').maphilight();

    $('#ma-link').mouseover(function(e) {
        $('#ma').mouseover();       
        }).mouseout(function(e) {
            $('#ma').mouseout();
        }).click(function(e) { e.preventDefault(); });

    $('#ri-link').mouseover(function(e) {
        $('#ri').mouseover();       
        }).mouseout(function(e) {
            $('#ri').mouseout();
        }).click(function(e) { e.preventDefault(); });
    $('#ct-link').mouseover(function(e) {
        $('#ct').mouseover();       
        }).mouseout(function(e) {
            $('#ct').mouseout();
        }).click(function(e) { e.preventDefault(); });

    $('#nj-link').mouseover(function(e) {
        $('#nj').mouseover();       
        }).mouseout(function(e) {
            $('#nj').mouseout();
        }).click(function(e) { e.preventDefault(); });

    $('#de-link').mouseover(function(e) {
        $('#de').mouseover();       
        }).mouseout(function(e) {
            $('#de').mouseout();
        }).click(function(e) { e.preventDefault(); });

    $('#md-link').mouseover(function(e) {
        $('#md').mouseover();       
        }).mouseout(function(e) {
            $('#md').mouseout();
        }).click(function(e) { e.preventDefault(); });

    });

Is there a way to simplify this?

Any help with this will be greatly appreciated.

Thanks.

No change to your HTML required. Just replace your block with this.

$(function() {
    $('.map').maphilight();

    $('[id$="-link"]').each(function() {
        var child = $("#" + this.id.substr(0,2));
        $(this).mouseover(function() {
             child.mouseover();
        }).mouseout(function() {
             child.mouseout();
        }).click(function(e) { e.preventDefault(); });
    });
});
