如何在ExtJS面板的标题中放置一个下拉列表？ [英] How can I put a dropdown in the header of an ExtJS panel?

问题描述

我可以将HTML元素如文本和图像放在面板标题中，如下所示：

I can put HTML elements such as text and images in a panel header like this:

var grid = new Ext.grid.GridPanel({
    region: 'center',
    style: 'margin: 10px',
    store: new Ext.data.Store({
        data: myData,
        reader: myReader
    }),
    headerCfg: {
        tag: 'div',
        cls: 'x-panel-header',
        children: [
            { tag: 'div', cls: 'panel_header_main', 'html': 'Shopping Cart' },
            { tag: 'div', cls: 'panel_header_icon1', 'html': '<img src="images/icon_plus.png" />' },
            { tag: 'div', cls: 'panel_header_icon2', 'html': '<img src="images/icon_pencil.png" />' },
            { tag: 'div', cls: 'panel_header_extra', 'html': 'Order Number: 2837428347' }
        ]
    },

看起来不错：

但是当我添加下拉元素这不是像这样的纯HTML：

but when I add dropdown element that is not plain HTML like this:

var grid = new Ext.grid.GridPanel({
    region: 'center',
    style: 'margin: 10px',
    store: new Ext.data.Store({
        data: myData,
        reader: myReader
    }),
    headerCfg: {
        tag: 'div',
        cls: 'x-panel-header',
        children: [
            { tag: 'div', cls: 'panel_header_main', 'html': 'Shopping Cart' },
            { tag: 'div', cls: 'panel_header_icon1', 'html': '<img src="images/icon_plus.png" />' },
            { tag: 'div', cls: 'panel_header_icon2', 'html': '<img src="images/icon_pencil.png" />' },
            { tag: 'div', cls: 'panel_header_extra', 'html': 'Order Number: 2837428347' },
            {
                width:          100,
                xtype:          'combo',
                mode:           'local',
                value:          'en',
                triggerAction:  'all',
                forceSelection: true,
                editable:       false,
                fieldLabel:     'Produkt',
                name:           'language',
                hiddenName:     'language',
                displayField:   'name',
                valueField:     'value',
                store:          new Ext.data.JsonStore({
                    fields : ['name', 'value'],
                    data   : [
                        {name : 'German',   value: 'de'},
                        {name : 'English',  value: 'en'},
                        {name : 'French', value: 'fr'}
                    ]
                })
            }
        ]
    },

它呈现脚本进入标题：

it renders script into the header:

是否可以将非HTML元素放在面板的标题中？如果是这样，它是如何做的？

推荐答案

你可能更好的把你的组合放在网格的工具栏。工具栏扩展Ext.Container，因此更适合包含其他Ext组件。尝试以下操作：

You're probably better off placing your combo in the grid's toolbar. Toolbars extend Ext.Container and are therefore much better suited for containing other Ext components. Try the following:

var grid = new Ext.grid.GridPanel({
region: 'center',
style: 'margin: 10px',
store: new Ext.data.Store({
    data: myData,
    reader: myReader
}),
tbar: new Ext.Toolbar({
    ctCls: 'panel-header',
    items: [
        { xtype: 'tbfill' },
        { tag: 'div', cls: 'panel_header_main', 'html': 'Shopping Cart' },
        { tag: 'div', cls: 'panel_header_icon1', 'html': '<img src="images/icon_plus.png" />' },
        { tag: 'div', cls: 'panel_header_icon2', 'html': '<img src="images/icon_pencil.png" />' },
        { tag: 'div', cls: 'panel_header_extra', 'html': 'Order Number: 2837428347' },
        {
            width:          100,
            xtype:          'combo',
            mode:           'local',
            value:          'en',
            triggerAction:  'all',
            forceSelection: true,
            editable:       false,
            fieldLabel:     'Produkt',
            name:           'language',
            hiddenName:     'language',
            displayField:   'name',
            valueField:     'value',
            store:          new Ext.data.JsonStore({
                fields : ['name', 'value'],
                data   : [
                    {name : 'German',   value: 'de'},
                    {name : 'English',  value: 'en'},
                    {name : 'French', value: 'fr'}
                ]
            })
        }
    ]
}),
