Object doesn't support property or method 'save'

Question

I am getting error while calling reportManager.save("/EditInitiatives.svc/SaveGridData"); method

<script type='text/javascript'>
$(function () {
    $('#saveReport, #save-report-bottom').click(function () {
        $.blockUI({ message: '<h4><img src="/Images/busy.gif" /> Saving your changes.<br/>This operation might impact several reports at once.<br/>Please be patient.</h4>' });
        uiController.disableSaveButton();
        reportManager.save("/EditInitiatives.svc/SaveGridData");
    });

    var reportManager = function () {
        var tableData = JSON.stringify(handsontable.getData());
        var input = JSON.stringify({ "input": tableData });
        alert("Data" +  input); 

        save = function(saveUrl) { 
            alert("save" + saveUrl);

            $.ajax({
                url: saveUrl,
                type: 'POST',
                dataType: 'json',
                data: input, //returns all cells' data
                contentType: 'application/json; charset=utf-8',
                success: function(res) {
                    if (res.result === 'ok') {
                        console.text('Data saved');
                    }                        
                    $.unblockUI();                            
                }, 
                error: function (xhr) {
                    alert(xhr.responseText);
                }                       
            });
        }
    };
}
</script>

You can not access it since save is a Global variable and not part of reportManager.

The reason why it is global is because you are missing the var in front of the variable. That puts it into the Global Namespace. It will not magically be hooked up to the block scope of the function. You would need to use an OO approach to get that to work. Some basic ideas are

function Report() {
     var x = 1;
    this.save = function () {
        alert("First: " + x);   
    }
}

var report = new Report();
report.save();


function report_2() {
     var x = 1;
    return {
        save : function () {
            alert("Second: " + x);   
        }
    }
}

var report2 = report_2();
report2.save();


var report_3 = (function () {
     var x = 1;

    var returnObj = {};
    returnObj.save = function () {
            alert("Third: " + x);   
    }

    return returnObj;


    //return {
    //    save  :  function() {
    //        alert("Third: " + x);   
    //    }
    //}
})();

report_3.save();
