我正在尝试将 JSON 字符串加载到 EXTJS 网格中。我得到的错误Uncaught TypeError: Cannot read property 'prototype' of undefined
来自 ext-all-debug.js。
这是我的js文件代码。
$(document).ready(function () {
var store = new Ext.data.Store(
{
proxy: new Ext.data.HttpProxy(
{
url: 'http://localhost:3197/Home/GetSecondaryOfferings'
}),
reader: new Ext.data.JsonReader(
{
root: 'items',
totalProperty: 'totalCount',
id: 'id',
fields: [{name:'CUSIP', mapping: 'CUSIP'},'DESCRIPTION','COUPONRATE','ASKPRICE']
})
});
store.load();
var grid = new Ext.grid.GridPanel({
store: store,
columns: [
{ header: 'CUSIP', dataIndex: 'CUSIP'},
{ header: 'Description', dataIndex: 'DESCRIPTION', width: 100 },
{ header: 'COUPONRATE', dataIndex: 'COUPONRATE', width: 100 },
{ header: 'ASKPRICE', dataIndex: 'ASKPRICE', width: 100 }
],
renderTo: 'example-grid2',
width: 1000,
autoHeight: true,
title: 'Employees'
});
});
这是返回的 JSON 文件的示例,它确实被返回了......
{"items":[{"CUSIP":"989701AL1","DESCRIPTION":"ZIONS BANCORPORATIONSB NT 5.65000% 05/15/2014","COUPONRATE":" 5.650","ASKPRICE":" 104.450"}],"totalCount":3316}
为了更好地衡量,这里是 .cshtml 文件。我正在使用 ASP MVC。
@{
ViewBag.Title = "About Us";
}
<h2>About</h2>
<p></p>
@section JavaScript
{
<link href ="@Url.Content("~/Content/resources/css/ext-all.css")" rel="Stylesheet" type="text/css"/>
<link rel="stylesheet" type="text/css" href=@Url.Content("~/Content/resources/css/ext-all.css") />
<link rel="stylesheet" type="text/css" href=@Url.Content("~/Content/examples/shared/example.css") />
<script type="text/javascript" src=@Url.Content("~/Content/bootstrap.js")></script>
<script type="text/javascript" src=@Url.Content("~/Content/examples/grid/FIO8472-JSON.js")></script>
}
<div id="example-grid"></div>
<div id="example-grid2"></div>
