ExtJS & IE7：简单窗口的渲染问题

发布于 2024-10-16 04:03:58 字数 2587 浏览 2 评论 0原文

我创建了这个非常简单的窗口扩展。在 Firefox 中，看起来应该如此，但在 IE7 中，包含的项目会从窗口中流出。

IE 中的渲染错误

我该怎么解决这个问题？

代码：（Doctype很严格，但由于某种原因不会显示）

I have created this very simple window extension. In Firefox it looks like it should, but in IE7, the contained items flow out of the window.

Wrong rendering in IE

What can I do to fix this?

Code: (Doctype is strict, but won't display for some reason)

溢出有什么原因吗？我的意思是，恕我直言，Ext.Window 不应该真正有滚动条，我更改了您的代码，因此它删除了滚动条，并且还应该删除 IE 中的元素溢出错误：

Ext.onReady(function(){

MyWindow = Ext.extend(Ext.Window, {
    resizable: true,
    closable: true,
    width: 400,
    closeAction: 'hide',
    collapsible: true,
    bodyStyle: 'padding:5px;',
    title: 'Window',

    initComponent: function () {

        var config = {
            items:
            [
                {
                    xtype: 'fieldset',
                    title: 'Buffer valg',
                    layout: 'form',
                    items:
                    [
                        {
                            xtype: 'numberfield',                                                                                                       
                            fieldLabel: 'Label'                                    
                        }, {
                            xtype: 'checkbox',
                            fieldLabel: 'Label',
                            checked: true                                    
                        }
                    ]
                }
            ]
        }

        Ext.apply(this, Ext.apply(this.initialConfig, config));

        // Config object has already been applied to 'this' so properties can 
        // be overriden here or new properties (e.g. items, tools, buttons) 
        // can be added, eg:

        // Call parent (required)
        MyWindow.superclass.initComponent.apply(this, arguments);
    }   
});

AWindow = new MyWindow();
AWindow.show();

如果情况并非如此，请告诉我。。

Is there any reason for the overflow at all? I mean, an Ext.Window should not really have scroll bars imho, I changed your code so it removes the scroll bars, and it should also remove the element overflow bug in IE:

Ext.onReady(function(){

MyWindow = Ext.extend(Ext.Window, {
    resizable: true,
    closable: true,
    width: 400,
    closeAction: 'hide',
    collapsible: true,
    bodyStyle: 'padding:5px;',
    title: 'Window',

    initComponent: function () {

        var config = {
            items:
            [
                {
                    xtype: 'fieldset',
                    title: 'Buffer valg',
                    layout: 'form',
                    items:
                    [
                        {
                            xtype: 'numberfield',                                                                                                       
                            fieldLabel: 'Label'                                    
                        }, {
                            xtype: 'checkbox',
                            fieldLabel: 'Label',
                            checked: true                                    
                        }
                    ]
                }
            ]
        }

        Ext.apply(this, Ext.apply(this.initialConfig, config));

        // Config object has already been applied to 'this' so properties can 
        // be overriden here or new properties (e.g. items, tools, buttons) 
        // can be added, eg:

        // Call parent (required)
        MyWindow.superclass.initComponent.apply(this, arguments);
    }   
});

AWindow = new MyWindow();
AWindow.show();

Let me know if this isn't the case...

我认为 Jaitsu 已经解决了这里的主要问题（使用 autoScroll: true），但我必须指出另一个缺陷。

为什么要写入initialConfig？

initComponent: function () {
    var config = {
        ...
    };
    Ext.apply(this, Ext.apply(this.initialConfig, config));

initialConfig 应该只包含传递给组件构造函数的配置。它在克隆组件时使用。甚至文档也说它是只读的。如果你不是 100% 确定那就不要这样做。此外，我不明白你为什么要这样做。当您像这样编写 initComponent 时，您的组件将正常工作：

initComponent: function () {
    // you can set all the config options directly to this.
    this.items = [
        ...
    ];
    MyWindow.superclass.initComponent.call(this);
}

I think Jaitsu already got the main issue here (the use of autoScroll: true), but I have to point out one other flaw.

Why are you writing to initialConfig?

initComponent: function () {
    var config = {
        ...
    };
    Ext.apply(this, Ext.apply(this.initialConfig, config));

initialConfig should only contain the config that is passed to the constructor of the component. And it is used when cloning the component. Even the docs say it is read-only. If you aren't 100% sure then don't do it. Besides, I don't see why you would want to do it. Your component will work just fine when you write initComponent like so:

initComponent: function () {
    // you can set all the config options directly to this.
    this.items = [
        ...
    ];
    MyWindow.superclass.initComponent.call(this);
}
