Question

In JQuery ~
I hope to make a simple character moving, Stop > Left || right.

This script make #moveCharacter turn left walk 10px once.

How can I keydown keep turn left walking,when keyup stop walking (like a character)??

// Left moving
$(document).keydown(function(e){

    if (e.keyCode == 37) { 
      $("#moveCharacter").animate({marginLeft: "-=10px"}, {queue:false});
       return false;
    }
});

2.I try to change keypress() but it has not work…..what wrong?

var xTriggered = 0;
$(document).keypress(function(e){
   xTriggered++;
    if (e.which == '37') { 

      $("#moveCharacter").animate({marginLeft: "-="+xTriggered+"px"}, {queue:false});
       return false;
    }
});

Answer 1

May this code will work as you want

    var xTriggered = 0;
    $(document).keydown(function(e){
    xTriggered++;
    if (e.which == '37') { 
    $("#moveCharacter").animate({marginLeft: "-="+xTriggered+"px"}, {queue:false});
          return false;
        }

//EDIT

$(document).keydown(function(e) {
  if(e.keyCode == 37) { // left
$("#moveCharacter").animate({ marginLeft: "-=10"}); 
}  
});
   $(document).keyup(function(e) { 
 $("#moveCharacter").queue("fx", []);
  $("#moveCharacter").stop();   });
