jQuery: textbox keyup firing twice

bind, jquery

Solution

I know it's been quite awhile, but I'm surprised nobody suggested:

txt.unbind();
txt.bind("keyup",function(event){
    if(event.keyCode==13)
    {
        var nu = $("#debug").html();
        nu+="<br>enter";
        $("#debug").html(nu);
    }
});

If somehow `txt` got bound already, calling unbind before your new bind should fix it. Of course it's preferable to figure out why it's being bound twice. This just happened to me, because I accidentally had my JavaScript file included twice. Calling unbind helped me determine that was the problem.

Problem

I'm having a textbox and assigned the following function (it's the only function assigned): ``` txt.bind("keyup",function(event){ if(event.keyCode==13) { var nu = $("#debug").html(); nu+="<br>enter"; $("#debug").html(nu); } }); ``` The strange thing is that it's actually firing twice, thus displaying "enter" twice in my debug window. Does anyone know what is causing this?
