Question

I have a function that looks exactly like this:

function exportSelectedToExcel(id)
{
    var selectedRows = new Array();

    //Retrieve selected items from the grid
    selectedRows = grid.getGridParam('selarrrow');

    //Always add the item in id, it doesn't matter if it's there twice.
    selectedRows[selectedRows.length] = id;

    //Build the url
    var params = selectedRows.join("&id="); 
    var exportUrl = "/Export/SelectListExporters?id=" + params;

    //Show the selection form
    SelectionWindow.show(exportUrl, "#selectionForm", 400);
}

Everytime I run this function the array grows with at least one item (the one i add to the end of it). This must surely mean that I have another array somewhere else in the system with the same name, right?

Is there any way in google chrome or firefox to find out where that variable is?

EDIT: There is no such variable in the whole project, verified from within visual studio.

EDIT 2: This is what I’m calling: http://www.secondpersonplural.ca/jqgriddocs/_2eb0fb79d.htm

EDIT 3: I’ve changed the code to start with the following:

var retrievedRows = grid.getGridParam('selarrrow');
var selectedRows = retrievedRows.slice(0);

Now it works like intended.

Answer 1

First of all, your code can be simplified to:

var selectedRows = grid.getGridParam('selarrrow');
selectedRows.push(id);

Looking at this it becomes obvious that grid.getGridParam() (whatever it is) is the cause of the problem. Debug this (possibly by printing selectedRows) and investigate it.

selectedRows is declared locally inside a function, so even if there is a global variables named the same, it will not affect your function.
