jqGrid 更改URL數據源後刷新數據

1、定義table

2、初始加載jqGrid

$(function () {
    $("#jqGrid").jqGrid({
        url: '../../../../list',
        datatype: "json",
        colModel: [
			{ label: 'id', name: 'id', index: 'ID', width: 50, key: true },
			{ label: '項目名稱', name: 'itemName', index: 'ITEM_NAME', width: 80 },
			{ label: '項目副標題', name: 'itemSecname', index: 'ITEM_SECNAME', width: 80 },
			{ label: '項目分類', name: 'itemType', index: 'ITEM_TYPE', width: 80 },
			{ label: '項目地址', name: 'address', index: 'ADDRESS', width: 80 },
			{ label: '省', name: 'province', index: 'PROVINCE', width: 80 },
			{ label: '市', name: 'city', index: 'CITY', width: 80 },
			{ label: '區', name: 'area', index: 'AREA', width: 80 },
			{ label: '所屬醫生', name: 'doctorId', index: 'DOCTOR_ID', width: 80 },
			{ label: '項目原價', name: 'price', index: 'PRICE', width: 80 },
			{ label: '項目折後價', name: 'discountPrice', index: 'DISCOUNT_PRICE', width: 80 },
			{ label: '項目簡介', name: 'descr', index: 'DESCR', width: 80 },
			{ label: '爆品服務值', name: 'score', index: 'SCORE', width: 80 },
			{ label: '預約人數', name: 'appointCount', index: 'APPOINT_COUNT', width: 80 },
			{ label: '預約基數', name: 'baseCount', index: 'BASE_COUNT', width: 80 }
        ],
		viewrecords: true,
        height: 385,
        rowNum: 10,
		rowList : [10,30,50],
        rownumbers: true,
        rownumWidth: 25,
        autowidth:true,
        multiselect: true,
        pager: "#jqGridPager",
        jsonReader : {
            root: "data.list",
            page: "data.currPage",
            total: "data.totalPage",
            records: "data.totalCount"
        },
        prmNames : {
            page:"page",
            rows:"limit",
            order: "order"
        },
        gridComplete:function(){
        	//隱藏grid底部滾動條
        	$("#jqGrid").closest(".ui-jqgrid-bdiv").css({ "overflow-x" : "hidden" });
        }
    });
});

3、更改數據源，刪除原來jqGrid中的數據，加載新數據

			$("#jqGrid").jqGrid('clearGridData');
			var itemURL = '../../../../list?itemType='+input_type.val();
			$("#jqGrid").setGridParam({url:itemURL}).trigger("reloadGrid");
