Mouseover event in jQuery

Question

I have the following mouseover function:

$('.msg_id').live("mouseover", function() {
    $(this).css('cursor', 'pointer');
    tid = $(this).attr('id');
    idx = $(this).attr('name');
    resp=""; 
    
    $.ajax({
        async: false, 
        url: "log_msg.asp",
        data: $("#msgForm").serialize() + "&aktion=popup&msg_id="+tid+"&msg_id"+idx,
        success: function(data){
            $("#"+tid).html(data);   
        }
        });

    //$.post("log_msg.asp", $("#msgForm").serialize() + "&aktion=popup&msg_id="+tid+"&msg_id"+idx,
        //function(data) {          
          
        //}).success(function(){
            //$("#"+tid).html(data);     
             //resp=data;
             //$('#bub'+tid).css('display', 'block');   
             //popd.css('display', 'block');    
            //});
    });

It puts some html code inside .msg_id ( $("#"+tid).html(data); ). The function mouseover is called in a loop. The ajax request is sent all the time while mouseovering it, not only once. How can I fix it? I have also tried mouseenter, but it fires in a loop too.

I don't get it. Why are you using mouseover for this? Why not click? — Fad

does it's something happening under the mouse cursor after the putting html content? — Samich

You might want to use the mouseenter() event instead, as mouseover will fire upon every move inside the element.

$('.msg_id').live("mouseenter", function() {
    //Do work here
});

or if live isn't required, simply:

$('.msg_id').mouseenter(function() {
    //Do work here
});

MouseOver():

Will fire upon entering an element can fire inside of any child elements.

MouseEnter():

Will fire upon entering an element, and only that element.

where did you get those descriptions? they validate the confusion around what they actually do...

Rion Williams Over a year ago

It's not necessary, was just mimicking it as OP used a live event in his. I'll include a non-live version as well.

jondavidjohn Over a year ago

ahh, didn't notice they used live.

The descriptions are from the jQuery documentation.

yeah, they need to have better explanations, it sounds like mouseover should work fine for the OP from that description.
