尝试加载以下视图端口时出错。我所有的搜索都表明,我在表单面板中没有定义任何区域,但我有。

Ext.onReady(function () {        
   
   var viewport = new Ext.Viewport({
        layout: 'border',
        items: []
    });
   
    var panel = new CR.FormPanel({
         region: 'center',
         title: 'Center Panel',
         frame: true         
    });
    
    viewport.add(panel);

});

在里面 ExtJS 3.2 文档 ,这里是的链接 viewport 和 BorderLayout .

在这个 FIDDLE ,我创建了一个演示使用 “视口” 具有 border 布局我希望这样 小提琴 将帮助您实现您的要求。

代码段

Ext.onReady(function() {
    var viewPort = new Ext.Viewport({
        layout: 'border',
        items: [{
            region: 'north',
            html: '<h1 class="x-panel-header">Page Title</h1>',
            autoHeight: true,
            border: false,
            margins: '0 0 5 0'
        }, {
            region: 'west',
            collapsible: true,
            title: 'Navigation',
            width: 200
            // the west region might typically utilize a TreePanel or a Panel with Accordion layout
        }, {
            region: 'south',
            title: 'Title for Panel',
            collapsible: true,
