Question

I have a function in jquery:

$('#map').click(function(e) {
    var posX = $(this).offset().left, posY = $(this).offset().top;
    if (posY < 100) {
       // do this

When the user clicks within that element it will run. But I also want it to run if he presses a cursor key.

Is it possible to do something like:

$('#map').click OR key.press(function(e) {

Basically, can you set more than one event to run that function?
Just learning jquery so go easy on me.

UPDATE

function move(e) {
   var posX = $(this).offset().left, posY = $(this).offset().top;

    if (posX > 75 && posX < 150 && posY < 75) { var go = "N"; }
    if (e.which == 38) { var go = "N"; }

    $.post("inc_map.php", { move: go }, function(data){ 
        var substr = data.split('@'); 
        if (substr[0] != "block") {
            var x1 = substr[0]; var y1 = substr[1];
            x = parseInt(x1) * 32; y = parseInt(y1) * 32;
            $("#mapview").css({ backgroundPosition: -x + "px " + -y + "px" });
                $("#map").html(substr[2]);
                $("#info").html(substr[3]);
                };
            $("#pos").html((x/32) + ', ' + (y/32)); 
        });  

};



$("#map").click(move).keypress(move);

Why doesnt this work? 😮

Answer 1

You’d define a function outside of the event handlers, then call it from each handler separately.

function myFunc(e) {
    var posX = $(this).offset().left, posY = $(this).offset().top;
    if (posY < 100) {

    }

    // if e.which equals 38, the up arrow was pressed
    if(e.which == 38) {
        // do nice stuff here
    }

    // the rest of your function here...
}

$("#map").click(myFunc).keypress(myFunc);

Edit: Threw in jQuery function chaining, too.

Aha, okay. I think I found your error. I’ve reformatted your code a bit and neatened it up some. Try this:

function move(e) {
    var posX = $(this).offset().left,
    var posY = $(this).offset().top;

    var go = "";

    if (posX > 75 && posX < 150 && posY < 75) {
        go = "N";
    }

    if (e.which == 38) {
        go = "N";
    }

    $.post("inc_map.php", {
        move: go
    }, function(data) {
        var substr = data.split('@');
        if (substr[0] != "block") {
            var x1 = substr[0];
            var y1 = substr[1];
            x = parseInt(x1) * 32;
            y = parseInt(y1) * 32;
            $("#mapview").css({
                backgroundPosition: -x + "px " + -y + "px"
            });
            $("#map").html(substr[2]);
            $("#info").html(substr[3]);
        };
        $("#pos").html((x / 32) + ', ' + (y / 32));
    });

};
