我的网络应用程序在 Firefox 或 Chrome 上运行良好,但在 IE 上运行不正常。它向我显示以下消息:

Object doesn't support this property or method

File: ext-all.js - Line: 7 - Char: 6100

有什么解决办法吗?

顺便说一句:我使用的是 ext 3.4。

编辑:我所有的分机布局创建者代码:

var tabs = Ext.getCmp('dynamic-tabs'); tabs.setActiveTab(0); });

这是一个简单的示例菜单。我在 IE 版本 8 中测试并使用兼容模式模拟 7。

有趣的观察:在 Firefox firebug 的控制台中显示:

  <html xmlns="http://www.w3.org/1999/xhtml" class=" x-viewport">
<head></head>
<body id="ext-gen5" class=" ext-gecko ext-gecko3 x-border-layout-ct">
etc...

IE 的开发者工具显示:

    <html class=" x-quirks  ext-border-box x-viewport">
<head>
<title></title>
<body class=" ext-ie ext-ie7 x-border-layout-ct" id="ext-gen5" scroll="no">

最佳答案

我之前遇到过这个错误。在我的例子中,我有一个名为 location 的实体,ext 从中创建了一个对象。现在 IE 使用 JS native 位置对象并尝试在其上执行方法。该错误看起来与您的错误非常相似。

使用 IE 开发人员工具栏并调试您的代码以识别确切的对象。我就是这样解决这个问题的!

根据新的演示代码进行编辑:

您的 HTML 文件应以

开头
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

我对这些设置从来没有遇到过任何问题。调试器可能看起来不同,因为 ExtJS 将在运行时添加类,但这应该是您的源 HTML 文件。
