JQuery, Passing Parameters

Question

Hi

I'm working with some very basic jquery code and would like to condense what I've done into one function with passed parameters.

I have a few of these:

$(".about").hover(function() {
    $(this).attr("src","_img/nav/about_over.gif");
     }, function() {
    $(this).attr("src","_img/nav/about_off.gif");
});


$(".artists").hover(function() {
    $(this).attr("src","_img/nav/artists_over.gif");
     }, function() {
    $(this).attr("src","_img/nav/artists_on.gif");
});


$(".help").hover(function() {
    $(this).attr("src","_img/nav/help_over.gif");
     }, function() {
    $(this).attr("src","_img/nav/help_off.gif");
});

But would obviously like to pass the the title of the image ("about", artists", "help") so that I could cut down on repeated code.

Any help much appreciated.

Thanks

Ronnie

Answer 1

function hover(img) {
    $("."+img).hover(function() {
 $(this).attr("src","_img/nav/"+img+"_over.gif");
    }, function() {
 $(this).attr("src","_img/nav/"+img+"_off.gif");
    });
}

I'm not sure what's going on with the second function in the hover function, but you can do something like this:

$(".about .artists .help").hover(function(){ $(this).attr('src','_img/nav/' + $(this).attr('class') + '_over.gif') });

you can apply the same principle to your on/off gifs too.

You could something like this:

function ElementHover(class_name, src_over, src_off) {
   $("."+class_name+"").hover(function() {
      $(this).attr("src", src_over);
      }, function() {
      $(this).attr("src", src_off);
   });

}

function HoverPic(name){
    $("."+name).hover(function() {
        $(this).attr("src","_img/nav/"+name+"_over.gif");
            }, function() {
        $(this).attr("src","_img/nav/"+name+"_off.gif");
    });
}
