如何在 ext.js 中的树视图中创建子项
how to create a child in a tree view in ext.js
我需要在树视图中创建一个子项,请帮助如何做。我已经试过了,但是没有用。
var myLocations = new Ext.Panel({
title: 'my work',
id: 'student',
height: 100,
autoScroll: true,
iconCls: 'myPanel',
// ,autoLoad: { url: 'UserLocDetails.aspx?UserName=' + strUser }
children: [{
text: "Leaf node (<i>no folder/arrow icon</i>)",
title: 'dasdasd',
leaf: true,
id: 'myLoc',
qtitle: 'Sample Tip Title',
qtip: 'Tip body'
}]
});
您需要创建一个 TreeStore
来存储树的数据,以及一些可以显示树的组件,例如 TreePanel
。试试下面的代码,它适用于 Ext JS 7.3.0 Classic Material,但可以被其他版本采用:
Ext.define('myTreeStore', {
extend: 'Ext.data.TreeStore',
root: {
expanded: true
},
proxy: {
type: 'memory',
reader: {
type: 'json'
}
},
data: {
children: [{
text: 'Main 1',
leaf: true
}, {
text: 'Main 2',
children: [{
text: 'Sub 21',
leaf: true
},{
text: 'Sub 22',
leaf: true
}]
}, {
text: 'Main 3',
leaf: true
}]
}
})
Ext.application({
name: 'Fiddle',
launch: function () {
const treeStore = Ext.create('myTreeStore');
Ext.create('Ext.tree.Panel', {
rootVisible: false,
renderTo: Ext.getBody(),
title: 'Tree Example',
width: 400,
store: treeStore,
});
}
});
