我正在使用我的应用程序示例

im试图将添加到它
i定义了一个新的类,但是当我打电话给我的表格网格时,我得到这个错误


$ b p> 未捕获TypeError:无法调用方法'insert'undefined



这是我的代码:

  Ext.define ('Ext.app.myFormGrid',{

extend:'Ext.grid.Panel',
别名:'widget.formgrid',
myData:[
['3m Co',71.72,0.02,0.03,'9/1 12:00 am'],
['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00 am'],

ds:Ext.create('Ext.data.ArrayStore',{
fields:[
{name:'company'},
{name:'price',type:'float'},
{name:'change',type:'float'},
{name:'pctChange',类型:'float'},
{name:'lastChange',类型:'date',dateFormat:'n / jh:ia'},
//评分取决于perf ormance 0 = best,2 = worst
{name:'rating',type:'int',convert:function(value,record){
var pct = record.get('pctChange');
if(pct if(pct 返回0;
















$ b $ {
if(val> 0){
return'< span style =color:green;>'+ val +'< / span>';
} else if(val return'< span style =color:red;>'+ val +'< / span>';
}
返回val;
},

pctChange:function(val){
if(val> 0){

initComponent:function(){
var gridForm = Ext.create('Ext.form.Panel',{
id:'company-form ',
frame:true,
title:'公司数据',
bodyPadding:5,
width:750,
layout:'column',//指定这些项目现在将按列排列

fieldDefaults:{
labelAlign:'left',
msgTarget:'side'
},

items:[{
columnWidth:0.60,
xtype:'gridpanel',
store:this.ds,
height:400,
title:'公司数据',

栏:[
{

text:'Company',

sortable:true,
dataIndex:'company'
},

{

渲染器:this.pctChange,
dataIndex:'pctChange'
},
{
text:'Last Updated',
width:85,
sortable:true,
renderer:Ext.util.Format.dateRenderer('m / d / Y'),
dataIndex:'lastChange'
},
{

width:30,

}
],

听众:{
selectionchange:function(model,records){
if(records [0]){
this.up('form')。getForm()。loadRecord(records [0 ]);
}
}
}
},{
columnWidth:0.4,
margin:'0 0 0 10',
xtype:' fieldset',
title:'公司详情',
默认值:{
width:240,
labelWidth:90
},
defaultType:'textfield ',
items:[{
fieldLabel:'Name',
name:'company'
},{
fieldLabel:'Price',
名称:'price'
},{
fieldLabel:'%Change',

xtype:'datefield',
fieldLabel:'最后更新',
名称:'lastChange'

fieldLabel:'Rating',
列:3,
默认值:{

},
items:[{

},{
inputValue:'2',
boxLabel:'C'
}]
}]
}],
// renderTo:bd
});


//gridForm.child('gridpanel').getSelectionModel().select(0);

},

});

然后在我的主文件中,我创建我的表单网格并将其添加到我的tabpanel:

  ... 

var myPanel = Ext.create('Ext.app.myFormGrid',{title: 'panel 2',height:250});

...

xtype:'tabpanel',

...

感谢您的时间和帮助

解决方案

首先,您需要定义一个类,在这个类中,您将从示例中放置var formGrid,但仅限于此。所有其他的东西,myData和逻辑都将在一个单独的文件中。然后你会在项目中说创建你定义的类。因此,并非来自示例的所有数据都将在课堂上(定义),而只是带有网格的面板。我试试这个,它适用于我。



在这里:第一个文件(类)

  Ext.define(app.formGrid,{
extend:Ext.form.Panel,
id:'company-form',
frame:true,
title:'公司数据',
bodyPadding:5,
宽度:750,
layout:'column',//指定项目现在按列排列

fieldDefaults:{
labelAlign:'left',
msgTarget:'side'
},

物品:[{
columnWidth:0.60,
xtype:'gridpanel',
商店:ds,
身高:400,
标题:'公司数据',

列:[
{
id:'company',
text:'Company',
flex:1,
sortable:true,
dataIndex: '公司'
},
{
text:'Price',
width:75,
sortable:true,
dataIndex:'price'
},
{
text:'更改',
width:75,
sortable:true,
renderer:change,
dataIndex:'change'
},
{
text:'%Change',
width:75,
sortable:true,
渲染器:pctChange,
dataIndex:'pctChange'
},
{
text:'Last Updated',
width:85,
sortable:true,
renderer:Ext.util.Format.dateRenderer('m / d / Y') ,
dataIndex:'lastChange'
},
{
text:'Rat ing',
width:30,
sortable:true,
renderer:rating,
dataIndex:'rating'
}
],

听众:{
selectionchange:function(model,records){
if(records [0]){
this.up('form')。getForm()。 loadRecord(记录[0]);
}
}
}
},{
columnWidth:0.4,
margin:'0 0 0 10',
xtype:' fieldset',
title:'公司详情',
默认值:{
width:240,
labelWidth:90
},
defaultType:'textfield ',
items:[{
fieldLabel:'Name',
name:'company'
},{
fieldLabel:'Price',
名称:'price'
},{
fieldLabel:'%Change',
名称:'pctChange'
},{
xtype:'datefield',
fieldLabel:'最后更新',
名称:'lastChange'
},{
xtype:'radiogroup',
fieldLabel:'Rating',
列:3,
默认值:{
名称:'rati ng'//每个电台都有相同的名称,因此浏览器将确保一次只检查一个
},
项目:[{
inputValue:'0',
boxLabel:'A'
},{
inputValue:'1',
boxLabel:'B'
},{
inputValue:'2',
boxLabel:'C'
}]
}]
}],

});

    });


    //gridForm.child('gridpanel').getSelectionModel().select(0);

},

});

then in my main file , i create my form grid and add it to my tabpanel:

...

var myPanel =  Ext.create('Ext.app.myFormGrid',{title : 'panel 2',height:250});

...

xtype : 'tabpanel',

...

thanks for ur time and help

解决方案

Ok,

first, you need to define a class, in this class you will put the "var formGrid" from example, only that. All the other stuff, myData, and logics are going to be in a separate file. Then you will say in items, "Create" the class that you have defined. So, not all data from example is going to be in class(define), but only the panel with the grid. I try this and it works for me.

here: first file(class)

Ext.define("app.formGrid",{
    extend:"Ext.form.Panel",
    id: 'company-form',
    frame: true,
    title: 'Company data',
    bodyPadding: 5,
    width: 750,
    layout: 'column',    // Specifies that the items will now be arranged in columns

    fieldDefaults: {
        labelAlign: 'left',
        msgTarget: 'side'
    },

    items: [{
        columnWidth: 0.60,
        xtype: 'gridpanel',
        store: ds,
        height: 400,
        title:'Company Data',

        columns: [
            {
                id       :'company',
                text   : 'Company',
                flex: 1,
                sortable : true,
                dataIndex: 'company'
            },
            {
                text   : 'Price',
                width    : 75,
                sortable : true,
                dataIndex: 'price'
            },

gridForm.child('gridpanel').getSelectionModel().select(0);

and the Ext.create in your main View:...

    items:[Ext.create("app.formGrid",{
            })]

Just to explain why I have sead that before: HERE!

II. Naming Conventions

1) Classes

  Classes that are not distributed by Sencha should never use Ext as the top-level namespace.
