The trouble caused by an extra comma

The problem is hidden above ie9, but on IE8, the error in easyui. Mini. JS is caused by an extra comma.

As follows:

Datatable_onsitedelegation.datagrid ({Title: 'onsite registration management', iconcls: 'icon-save', method: "Post", URL: '/samplereceive/loadonsitedelegationjson/', idfield: 'id', sortname: 'id', sortorder: 'asc ', pagesize: 20, striped: True, // display the zebra effect fit: True, pagination: True, // if it is true, the pagination toolbar is displayed at the bottom of the data table control. Rownumbers: True, fitcolumns: false, // the size of the column is automatically expanded/shrunk to fit the width of the grid and prevent horizontal scrolling. Singleselect: True, // if it is true, only one row can be selected. Columns: [[// {field: 'ck ', checkbox: true}, // {field: 'id', Title: 'id', width: 30, sortable: true, frozen: true}, // indicates the current status {field: 'teststatus', Title: 'type', width: 60, formatter: function (value) {Switch (value) {Case-1: Return "remote"; break; default: Return "onsite"; break ;}},{ field: 'sampleid', Title: 'sample number ', width: 80, sortable: True, frozen: true}, {field: 'serialnum', Title: 'factory number', Width: 100}, {field: 'name', Title: 'name', width: 80, sortable: True, frozen: true}, {field: 'type ', title: 'model', width: 100}, {field: 'mermername', Title: 'inspection unit ', width: 100}, {field: 'worktype', title: 'Job type', width: 100}, {field: 'submitdate', Title: 'submission date', width: 150, formatter: function (value) {var Re = /-? \ D +/; var M = re.exe C (value); If (M = NULL) {// alert ("the submission date field of the current record is blank! "); Return NULL;} var d = new date (parseint (M [0]); // return the date return in the format of [09:09:09. format ("yyyy-mm-dd hh: mm: SS") ;}}], onclickrow: function (rowindex, rowdata) {// alert ("th" + rowindex + "Row clicked"); updatebtnstatus (rowdata. teststatus) ;}, toolbar: [{text: "add", iconcls: 'icon-add', Handler: addonsitedelegation}, '-', {text: "edit ", iconcls: 'icon-edit', Handler: editonsitedelegation, ID: 'onsitedelegation _ editbtn '},'-', {text: "delete", iconcls: 'icon-delete ', handler: delonsitedelegation}, '-',]});

Note that a comma is added after "-" to make easyui think that there is a toolbar behind it, resulting in invalid BTN. Handler
