ExtJS 无法正确显示 Ext.panel.Panel 的 html

Question

我有一个 class 继承自 Ext.grid.Panel 并使用此 class 中的方法显示一个 panel，其中包括两个项目：一个 listtoolbar class 和一名 Ext.XTemplate 员工。

Ext.define('MyApp.view.BGrid', {
    extend: 'MyApp.view.AGrid', //This class extends from 'Ext.grid.Panel'
    requires: [
            ...
            'Ext.layout.container.VBox',
            'MyApp.view.base.ListToolbar'
    ],
    getDashBoardTpl: function () {
        var me = this;

        return [
            {
                xtype: 'panel',
                // html: 'so what?', // Displays the text; See -Img 01
                // html: me.dashTpl(), // Displays as [object object]; See -Img 02
                layout: {type: 'vbox', align: 'stretch', pack: 'center'},
                items:
                    [
                        {
                            xtype: 'listtoolbar', //Display nothing!
                            flex: 1
                        },
                        {
                            xtype: 'panel',
                            name: 'dashtpl',
                            flex: 1,
                            // html: 'so WHat?' //Display nothing!
                            html: me.dashTpl() //Display nothing!
                        }
                    ]
            }
        ]
    },

无法显示面板的项目； listtoolbar 和 dashtpl 的 html。而不是当 html 标签使用上面板时它起作用。当第一个面板中使用 dashTpl 函数时，事情就是显示 [Object] [Object]。

这里是 dashTpl();

dashTpl: function(){
        var tpl= new Ext.XTemplate(
            '<tpl for=".">' +
                '<div class="dashTpl">'+
                    '<table style="width:100%;height:80px;text-align:center" >'+
                        '<tr style="width:100%;">'+
                            '<td style="box-shadow: 10px 5px 5px #BDBDBD;background-color:#EEEEEE;width:20%">'+
                                '<a>'+
                                    '<span style="font-size:24px;"><b style="color: #8000FF;">5,875.00</b></span><br/>'+
                                    '<div>'+
                                        '<b style="color: #6E6E6E;font-size:14px;">€</b>' +

这可能是什么原因？谢谢指教。

@Nuri，在您的代码中设置 html using Ext.XTemplate inside of panel，这不是使用 html 配置的正确方法。

If you want to use html config in panel then you need to set tpl like below example

html:'<table class="x-date-table"><tbody><tr><th>SNo.</th><th>Date</th><th>Event</th><th>Venue Details</th></tr><tr><td>1</td><td>12 February</td><td>Waltz with Strauss</td><td>Main Hall</td></tr><tr><td>2</td><td>24 March</td><td>The Obelisks</td><td>West Wing</td></tr><tr><td>3</td><td>15 February</td><td>Kolidoscop</td><td>Reception Hall</td></tr><tr><td>4</td><td>24 March</td><td>The data center</td><td>UDM</td></tr></tbody></table>'

If you want to use tpl/Ext.XTemplate config in panel then you need to set tpl like below example

tpl: new Ext.XTemplate(
    //start table
    '<table class="x-date-table">',
    //Header of my table
    '<tr>',
    '<th>SNo.</th>',
    '<th>Date</th>',
    '<th>Event</th>',
    '<th>Venue Details</th>',
    '</tr>',
    //Looping insdie tpl for creating multiple row depend on data
    '<tpl for=".">', //Start loop tpl
    '<tr>',
    '<td>{#}</td>',
    '<td>{date}</td>',
    '<td>{event}</td>',
    '<td>{venue}</td>',
    '</tr>',
    '</tpl>', //End loop tpl
    '</table>' //Close table
)

在这个 FIDDLE 中，我使用与上述相同的方式创建了一个演示。希望这对您有所帮助或指导您实现您的要求。

        function doGetHtml(arr) {
            let html = `<table class="x-date-table"><tr><th>SNo.</th><th>Date</th><th>Event</th><th>Venue Details</th></tr>`;

            arr.forEach((item, index) => {
                html += `<tr><td>${index+1}</td><td>${item.date}</td><td>${item.event}</td><td>${item.venue}</td></tr>`;
            });
            return `${html}</table>`
        }

        //Panel show data with HTMl
        Ext.create('Ext.panel.Panel', {
            renderTo: Ext.getBody(),

            html: doGetHtml(data)
        });
