如何在GeoExt中同时使用Ext 3和Ext 4? [英] How to use both Ext 3 and Ext 4 togeheter with GeoExt?
问题描述
我们正在尝试使用ext-all-sandbox.js加载Ext 3和Ext 4，以便能够在Ext 4中使用GeoExt.
We are trying to load both Ext 3 and Ext 4 with the use of ext-all-sandbox.js to be able to use GeoExt in Ext 4.
查看我们的DOM，似乎我们已经成功加载了Ext 3, Ext 4, GeoExt和OpenLayers，但仍收到诸如以下错误:
Looking in our DOM it seems we have succeeded with loading Ext 3, Ext 4, GeoExt and OpenLayers but are still getting errors like:
"Ext.functionFactory()不是函数"，而"Ext.supports是 未定义".
"Ext.functionFactory() is not a function" and "Ext.supports is undefined" .
有没有人尝试过类似的事情?
Is there anyone out there that have tried a similar thing?
这是我们正在加载js文件的index.jsp.
This is the index.jsp where we are loading the js files.
<!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">

<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>
以及我们将GeoExt与Ext 3和Ext 4一起使用的地方:
and where we use GeoExt together with Ext 3 and Ext 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'
});
}
}
});
}
});

推荐答案
我们在解决了许多问题后进行了管理:
We managed after alot of problems to solve it:
<script type="text/javascript" src="../gt-static/ext-3.3.1/adapter/ext/ext-base.js"></script>
<script src="../gt-static/ext-3.3.1/ext-all.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="../gt-static/ext-3.3.1/resources/css/ext-all.css"></link>
<script src="../gt-static/OpenLayers/OpenLayers/OpenLayers.js" type="text/javascript"></script>
<script src="../gt-static/GeoExt/lib/GeoExt.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="../gt-static/GeoExt/resources/css/geoext-all.css"></link>
<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-sandbox.css"/>
现在可以将GeoExt MapPanel加载到Ext 4容器中.
Now it is possible to load a GeoExt MapPanel into a Ext 4 container.
现在我们的问题是CSS文件似乎可以作为ext-all-gray.css
Now our problem is that the CSS files dosent seem to work as the ext-all-gray.css
如果你们在那里有想法，将不胜感激
If u guys out there have thoughts about that it would be very appreciated
