Answer 1

Insert preventDefault() to avoid other events than yours...

$(document.documentElement).keyup(function(event) { 
    // handle cursor keys 
    event.preventDefault();
    if (event.keyCode == 37) { 
        $(".prev").click(); 
    }
});

EDIT check this answer if you're using IE8

Answer 2

try this using one will prevent a second call

$(".prev").one("click",function(){
//your stuff
});
