Question

我们尝试使用ext-all-sandbox.js加载Ext 3和Ext 4，以便能够在GeoExt中使用Ext 4。

查看我们的DOM，似乎我们已经成功加载Ext 3, Ext 4, GeoExt和OpenLayers但仍然遇到如下错误：

“Ext.functionFactory（）不是函数”和“Ext.supports” 未定义“。

有没有人尝试过类似的事情？

这是我们加载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>

以及我们将GeoExt与Ext 3和Ext 4一起使用的地方：

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'
                    });
                }
            }
        });
    }
});

我们解决了很多问题后才解决它：

<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。

现在我们的问题是CSS文件看起来像ext-all-gray.css

如果你们有人想到这一点会非常感激

如何使用GeoExt同时使用Ext 3和Ext 4？
