Question

can somebody tell me what is wrong?

JS Code

$.ajax({
    url:"http://www.google.com/complete/search?qu=chicken",
    success:function(data){

        var test_data = ''+data+''; // convert object to a string
        $('body').append(typeof(test_data));

        var test_data = replace.test_data(/[0-9]/,'X');
        $('body').append('<hr />'+test_data+' <hr />');

    },
    dataType:'jsonp',
    error:function(){
        alert('error');
    }
});

Thanks in advance!

Answer 1

You got it backwards; it should be

test_data.replace(...);

Also, you don’t need var before the second assignment to “test_data”; just the first one.
