I am trying to obtain a cell's text value from a flexigrid.However I keep getting that error.This is my function for retrieving a specific cell's text(Flexigrid doesnt have "attr" it has "abbr" instead).\[code\]function getSelectedCopyDates() { var arr = new Array(); debugger; //for every row that has a checked checkbox $("tr").has(".noteCheckBox:checked").each(function(i) { if ($(this.id) !== "checkAllNotes") { //push the value of column(FName, LName) into the array arr.push($("#" + this.id + "> td[abbr='EventDate'] > div").text()); } }); return arr;}\[/code\]I only get that error when I click on "checkAllNotes"(main check box ). If I check a checkbox manually then everything works fine.Here is my flexigrid layout:\[code\]$('#viewNotesGrid').flexigrid({ url: url, dataType: 'json', method: 'get', colModel: [{ display: '<input type="checkbox" class="noteCheckBox" id="checkAllNotes" />', name: 'checkBox', width: 20, sortable: false, align: 'center', process: showDescription }, { display: 'Date', name: 'EventDate', width: 80, sortable: true, align: 'center', process: showDescription },\[/code\]
