jQuery〜函数，仅与警报一起使用

Question

I have the following function that is actually working on Chrome and Firefox, but its´not working in Internet Explorer

$(".info").on("click", function(e){
        //alert("Message");
        if(tp==0){
            fila[0]=$(this).children();
            fila[1]=$(this).children().slice(0,2);
            var x = $(this).children().children().children().attr('title');

            var tot="<td colspan='7' style='font-size:22px;'>"+x+"</td>";
            $(this).html(fila[1][0]);
            $(this).append(fila[1][1]);
            $(this).append("<td colspan='7' style='font-size:22px;'>"+x+"</td>");
        }
        tp=1;
    });

I make it works on IE if the alert line is uncommented like this:

$(".info").on("click", function(e){
        alert("Message");
        if(tp==0){
            fila[0]=$(this);
            fila[1]=$(this).slice(0,2);
            var x = $(this).attr('title');

            var tot="<td colspan='7' style='font-size:22px;'>"+x+"</td>";
            $(this).html(fila[1][0]);
            $(this).append(fila[1][1]);
            $(this).append("<td colspan='7' style='font-size:22px;'>"+x+"</td>");
        }
        tp=1;
    });

The question is, how can I make it works without this alert on IE? Sorry for my bad English.

For those that ask me, here is where I def my "tp"

<script type="text/javascript">
     var pedidos_carritos = [];
     var linea = [];
     var cont;
     var aux=0;
     var tp=0;
     var fila =[];

Answer 1

Just put console.log("your message") instead of an alert and check if it works. I am not sure.

Answer 2

Until you can fix this in IE, you need to know which line of code isn't working. You've only put your alert in one place. Try putting it AFTER the if statement and then try every line after that until you can pinpoint it down.

You could also step through in the debugger, but above will be easier if you have never done this.

Is this code at the bottom of the page / in a document ready function?
