vs2012开发Ext，Grid显示空行问题
如题，vs2012开发Ext，后台数据库数据调用成功，并已经转化为JSON格式，但是Grid只显示空行，没有具体数据显示，求帮忙解答
var EquInfoStore;ExtJS Visual?Studio?2012
EquInfoManage = function (node) {
//分页每页显示数量
var pageSize = 12;
//指定列参数
var fields = ["equid", "equname", "equteachername", "equdate", "equtime", "equaddress"];
EquInfoStore = new Ext.data.Store({
proxy: new Ext.data.HttpProxy(
{
url: "DATA/EquInfo/EquInfo.aspx",
method: "POST"
}),
reader: new Ext.data.JsonReader(
{
fields: fields,
root: "data",
id: "equid",
totalProperty: "totalCount"
})
});
//加载参数
EquInfoStore.load({ params: { start: 0, limit: pageSize } });
//--------------------------------------------------列选择模式
var sm = new Ext.grid.CheckboxSelectionModel({
dataIndex: "equid"
});
//--------------------------------------------------列头
var cm = new Ext.grid.ColumnModel([
sm, {
header: "课程ID",
dataIndex: "equid",
tooltip: "课程唯一标识",
//可以进行排序
sortable: true
}, {
header: "课程名称",
tooltip: "课程名称",
width: 130,
dataIndex: "equname",
sortable: true,
renderer: function (value) {
return "<b>" + value + "</b>";
}
}, {
header: "指导老师",
tooltip: "老师姓名",
//dataIndex: "guestname",equteachername
dataIndex: "equteachername",
sortable: true,
renderer: function (value) {
return "<font color=#EE9572>" + value + "</font>";
}
}, {
header: "实验日期",
tooltip: "实验日期",
//dataIndex: "guestname",equteachername
dataIndex: "equdate",
sortable: true,
renderer: function (value) {
return "<font color=#EE9572>" + value + "</font>";
}
}, {
header: "实验时间",
tooltip: "实验时间",
dataIndex: "equtime",
sortable: true,
renderer: function (value) {
return "<b>" + value + "</b>";
}
}, {
header: "实验地点",
width: 220,
tooltip: "实验地点",
dataIndex: "equaddress",
//可以进行排序
sortable: true
}]);
//----------------------------------------------------定义grid
var EquInfogrid = new Ext.grid.GridPanel({
id: "EquInfogrid",
store: EquInfoStore,
sm: sm,
cm: cm,
loadMask: true,
//超过长度带自动滚动条
autoScroll: true,
border: false,
viewConfig: {
columnsText: "显示/隐藏列",
sortAscText: "正序排列",
sortDescText: "倒序排列",
forceFit: true
}
});
//传入icon样式
GridMain(node, EquInfogrid, "guesticon");
}
