Question

I got the following javascript code.
And Basically, it works on FF, and IE with developer Tools.

$(function(){
    console.log("it is ok");
    var mybutton="";

    alert("ready1");
    $('button[name="delorder"]').click(function(){

        console.log($(this).val()+"hay i got a click");
        mybutton=$(this).val();
        alert("a click1");
        $.ajax({
            type:'POST',
            url:'deleteorderitem.php',
            data:mybutton,
            success:function(result){

                if((result.indexOf("t") < 3) && (result.indexOf("t") >= 0)){                    

                    $('#orderresult').html(result);                 

                    console.log("i am 3 ");
                    console.log("index of t is "+result.indexOf("t"));
                }else{
                    console.log("i am 4");                      
                    console.log("index of t is "+result.indexOf("t"));
                    $('#divOrderButton').hide();
                    $('#orderresult').html("");
                    $('#divNoinfo').html("There is no record to display at the moment.");
                    $('#divNoinfo').show(); 
                    $('#divOrder').hide();
                }
            }
        });
    });
});
</script>

But , it does NOT WORK on IE (without developer tools).
so, any advice will be appreciated.
Thanks

Answer 1

It is mostly because of

console.log()

Windows IE8 and below has no console object when the Developer tools is not open.

Either comment out the lines that says console. Or create the console object beforehand.

Try this … Not sure if this is the correct way around..

var alertFallback = true;
   if (typeof console === "undefined" || typeof console.log === "undefined") {
     console = {};
     if (alertFallback) {
         console.log = function(msg) {
              alert(msg);
         };
     } else {
         console.log = function() {};
     }
   }

This will create the console object if it is not present.
