    Question keydown to trigger an event??

    I'm trying to get a keydown function to trigger an event... The same as the onclick event I currently have working...

    I got the buttons to work on keydown, but I cant get them to work just like the onclick. Trying to get them to do the same thing.

    This is what i have.

    Code:

    $(document).ready(function(){
    	
    	// controls bottom div
    	$("#bottomControl").click(function() {
    		$(".innderDiv").hide();
    		$(".innderDiv").css("z-Index","0");
    		$("#bottomDiv").css({"margin-top":"400px",
    						     "display":"block",
    							 "z-index":"10"});
    		$("#bottomDiv").animate({
    			marginTop: "0px"
    		},500);
    		
    		$("#bottomControl").html("Black on White");
    		$("#bottomDiv").css("background-image","url(images/logo4.png)");
    			
    	});
    	
    		
    	// controls top div
    	$("#topControl").click(function() {
    		$(".innderDiv").hide();
    		$(".innderDiv").css("z-Index","0");

    		$("#topControl").html("White on Black");
    		$("#topDiv").css("background-image","url(images/logo3.png)");
    		
    	});
    	// controls right div
    	$("#rightControl").click(function() {
    		$(".innderDiv").hide();
    		$(".innderDiv").css("z-Index","0");
    		$("#rightDiv").css({"margin-left":"400px",
    						     "display":"block",
    							 "z-index":"10"});
    		$("#rightDiv").animate({
    			marginLeft: "0px"
    		},500);
    		
    		$("#rightControl").html("Red on White");
    		$("#rightDiv").css("background-image","url(images/logo2.png)");
    		
    	});
    	// controls left div
    	$("#leftControl").click(function() {
    		$(".innderDiv").hide();
    		$(".innderDiv").css("z-Index","0");
    		$("#leftDiv").css({"margin-left":"-400px",
    						     "display":"block",
    							 "z-index":"10"});
    		$("#leftDiv").animate({
    			marginLeft: "0px"
    		},500);
    		
    		
    		$("#leftControl").html("White on Red");
    		$("#leftDiv").css("background-image","url(images/logo1.png)");
    		
    	});	
    
    });
    
    // press key function
    $(window).keydown(function(e) {
        key = (e.keyCode) ? e.keyCode : e.which;
        $('.key.c' + key).addClass('keydown');
        console.log(key);
    	
    });
    
    $(window).keyup(function(e) {
        key = (e.keyCode) ? e.keyCode : e.which;
        $('.key.c' + key).removeClass('keydown');
    });
    I just want the keydown function to do the same thing the onclick does.

    This should work:

    Code:
    // press key function
    $(window).keydown(function(e) {
        key = (e.keyCode) ? e.keyCode : e.which;
        //add switch block for different keys
        $("#bottomControl").trigger('click');
    	
    });

    markle976... You're a genius! Now, how would I add a switch block? Sorry for my lack of intelligence, this stuff takes a while to get used to. I greatly appreciate you!

    A switch statement is like an if statement with multiple options. I don't know the exact key codes, but it would look something like this:

    Code:
    var key = (e.keyCode) ? e.keyCode : e.which;
    switch(key) {
    	case 13:
    		//execute this code block if key == 13
    		$("#bottomControl").trigger('click');
    		break;
    	case 27:
    		//execute this code block if key == 27
    		$("#topControl").trigger('click');
    		break;
    	default:
    		//code to be executed if key is different from case 1 and 2
    }
    Create as many cases as you need.
    And, don't apologize for a lack of intelligence - all you need is practice... and google.
