asp.net mvc4 jquery get value from ajax

Question

I have asp.net mvc4 project where I'm use an ajax query to get data from my server side

$.getJSON('/Administrator/GetStudentAppNumbers/', function(data) {
        //alert(data[0]);
        $.each(data, function (i, appNumber) {
            var program = $('"#' + appNumber + '"').html();
            var newProgram = $.trim(program).replace(/\s/g, " ");
            var shortText = $.trim(newProgram).substr(0, 40) + "...";
            $('"#' + appNumber + '"').html(shortText);
            $('"#' + appNumber + '"').click(function () {
                alert(newProgram);
            });
        });
    });

But when I try to invoke it in console, they return me an error:

Uncaught Error: Syntax error, unrecognized expression: "#UZ43"

And when I try to invoke it from alert(appNumber); they return me UZ43.

Have any ideas where I mistake?

The double quotes shouldn't be part of the value of the selector:

$('"#' + appNumber + '"')

Should be:

$('#' + appNumber)

With $("#UZ43"), the value of the selector is #UZ43.

With $('"#' + appNumber + '"'), the value is "#UZ43".

Your selector is incorrect, so you are trying to call html() on a string; hence the error. Try this:

var program = $('#' + appNumber).html(); // note the removed double quotes (")

Try replacing

 $('"#' + appNumber + '"').html(shortText);

with

 $('#' + appNumber).html(shortText);
