我們正在嘗試加載Ext 3
和Ext 4
,並使用ext-all-sandbox.js以便能夠在Ext 4
中使用GeoExt
。如何使用Ext 3和Ext 4來創建GeoExt?
展望我們的DOM看來我們已經成功地與裝載Ext 3, Ext 4, GeoExt
和的OpenLayers但仍然得到這樣的錯誤:
「Ext.functionFactory()不是一個函數」和「Ext.supports是 未定義「。
有沒有人試過類似的東西?
這是我們加載js文件的index.jsp。
<!DOCTYPE HTML>
<%@ page pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<!-- Ext 4 with sandbox mode -->
<script type="text/javascript" src="../gt-static/extjs/ext-all.js"></script>
<script type="text/javascript" src="../gt-static/extjs/builds/ext-all-sandbox.js">
</script>
<link rel="stylesheet" type="text/css" href="../gt-static/extjs/resources/css/ext-all-gray.css"/>
<link rel="stylesheet" type="text/css" href="../gt-static/extjs/resources/css/ext-sandbox.css">
<!-- Ext 3 -->
<script src="../gt-static/ext-3.2.1/adapter/ext/ext-base.js" type="text/javascript"> </script>
<script src="../gt-static/ext-3.2.1/ext-all.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="../gt-static/ext-3.2.1/resources/css/ext-all.css"></link>
<!-- OpenLayers -->
<script src="../gt-static/OpenLayers/OpenLayers/OpenLayers.js" type="text/javascript"></script>
<script type="text/javascript">
// Start app on ready
Ext4.Loader.onReady(function(){
Ext4.Loader.setConfig({enabled: true});
Ext4.require(['Ext4.picker.Date']);
var head = Ext4.fly(document.getElementsByTagName('head')[0]);
// GeoExt
Ext4.core.DomHelper.append(head, {
tag : 'script',
type : 'text/javascript',
src : '../gt-static/GeoExt/lib/GeoExt.js'
});
Ext4.core.DomHelper.append(head, {
tag : 'script',
type : 'text/javascript',
src : '../gt-static/GeoExt/resources/css/geoext-all-debug.css'
});
Ext4.core.DomHelper.append(head, {
tag : 'script',
type : 'text/javascript',
src : 'app.js'
});
},this,true);
</script>
</head>
<body></body>
</html>
和我們一起用GeoExt與擴展3和分機4:
Ext4.define('GT.controller.Authenticated', {
extend : 'Ext4.app.Controller',
views : [ 'Authenticated' ],
init : function() {
"use strict";
this.control({
'authenticated' : {
render : function() {
var panel = new Ext.Panel({
title : 'EXT3'
});
Ext4.getCmp('mappanel').add(panel);
var map = new OpenLayers.Map();
var layer = new OpenLayers.Layer.WMS("Global Imagery",
"http://maps.opengeo.org/geowebcache/service/wms",
{
layers : "bluemarble"
});
map.addLayer(layer);
new GeoExt.MapPanel({
renderTo : 'mappanel',
height : 400,
width : 600,
map : map,
title : 'A Simple GeoExt Map'
});
}
}
});
}
});

事件的看法,在網頁中加載ExtJs **兩次**看起來很奇怪......它已經非常沉重。 – tonio
我明白了你的觀點,可以說讓IE8不能在DOM中處理很多問題,這會是一個問題嗎? – Emil
