jqgrid not work on IE8

问题

my below code not worked on IE 8. Its a JQGrid (treegrid) to display treegrid format from json server. it worked at firefox.

$(function () {
    "use strict";
    $("#tree").jqGrid({
        url: "http://myJSON-URL/",
        datatype: "json",

        colNames: ['id', 'Prestations'],
        colModel: [
                { name: 'id', width: 100, key: true, hidden: true },
                { name: 'name', width: 785, sortable: false }
            ],
        sortname: 'id',
        sortorder: "asc",
        hiddengrid: true,
        gridview: true,
        treeGrid: true,
        treeGridModel: "adjacency",
        ExpandColumn: 'name',
        ExpandColClick: true,
        jsonReader: { repeatitems: false, root: function (obj) { return obj; } },
        height: "auto"
    });
});

I think its AJAX cors problem. Any idea? thanx.

The json server side responsed these:

 json = [
{
    "id": "1",
    "name": "ECHANGEUR",
    "level": "0",
    "parent": "null",
    "isLeaf": false,
    "expanded": false,
    "loaded": true
},
{
    "id": "1_1",
    "name": "Intervention Aller sur Site",
    "level": "1",
    "parent": "1",
    "isLeaf": false,
    "expanded": false,
    "loaded": true
},
{
    "id": "1_1_1",
    "name": "Date et heure d'arrivée sur le site",
    "level": "2",
    "parent": "1_1",
    "isLeaf": true,
    "expanded": true,
    "loaded": true
},
{
    "id": "1_1_2",
    "name": "Consignation de l'échangeur",
    "level": "2",
    "parent": "1_1",
    "isLeaf": true,
    "expanded": true,
    "loaded": true
}

];

You have just the problem with the bug specific for jqGrid 4.7.x. You can try tree demos which uses different versions of jqGrid and the same code and JSON which you posted:

demo46, demo47, demo48, demo-free-jqGrid-GitHub.

(The last one uses free jqGrid 4.8 which I published recently, see here and here).

You can verify that the demo which uses jqGrid 4.7 only have the problem in IE8 and both other demos have no problem. You can read more about the bug here or here.
