jqgrid定义多选操作

先定义：    var SelectRowIndx;

然后加入以下属性：

        multiselect: true,
        onSelectRow: function () {
            SelectRowIndx = GetJqGridRowIndx("#" + this.id);
        },
        gridComplete: function () {
            $("#" + this.id).jqGrid('setSelection', SelectRowIndx);
        }

举例：

<script type="text/javascript">
    $(function () {
        GetGrid();
    })

    //加载表格
    function GetGrid() {
        var SelectRowIndx;
        $("#gridTable").jqGrid({
        url: "@Url.Content("~/School/ClassInfoes/GridPageListJson")",
        datatype: "json",
        height: $(window).height() - 149,
        auto true,
        colModel: [
                { label: 'Id', name: 'id', index: 'id',  0, align: 'left', sortable: true, hidden: true },
                { label: '所属学校', name: 'schoolname', index: 'schoolname',  120, align: 'center', sortable: true },
