如何从ExtJS网格显示具有不同存储区的嵌套对象
如何从ExtJS网格显示具有不同存储区的嵌套对象
提问于 2021-02-09 21:45:36
我想在Ext Grid上父对象的子对象上进行REST操作。我需要使用rowExpander，而不是rowWidget，因为我使用的是现代工具包。
以下是我的API中的示例JSON数据：
{
"pagination": {
"page": 1,
"limit": 20,
"total": 1,
"hasPreviousPage": false,
"hasNextPage": false
},
"data": [
{
"id": 2,
"customer": "Mark",
"dateRented": "2021-02-09T21:18:40.667",
"movieRentals": [
{
"id": 5,
"rentalDetailDtoId": 2,
"movie": "Shingeki no Kyojin",
"dateReturned": null
},
{
"id": 6,
"rentalDetailDtoId": 2,
"movie": "Insidous 2",
"dateReturned": null
}
]
},
{
"id": 1,
"customer": "Samuel",
"dateRented": "2021-02-09T21:17:18.403",
"movieRentals": [
{
"id": 3,
"rentalDetailDtoId": 1,
"movie": "Home Alone",
"dateReturned": null
},
{
"id": 4,
"rentalDetailDtoId": 1,
"movie": "Neighbors",
"dateReturned": null
}
]
}
]
}我想为每个客户显示它，并且我在movieRentals对象上有一个REST操作POST。我想使用RowExpander，但我不确定如何使用它。
这是我当前的ExtJS网格代码：
Ext.define('Vidly.view.rental.DisplayRentalsView', {
extend: 'Ext.grid.Grid',
xtype: 'displayrentalsview',
reference: 'rentallist',
title: 'Rental List',
controller: 'displayrentalsviewcontroller',
viewModel: 'rentalsviewmodel',
reference:'displayrentalsviewgrid',
selType: 'rowmodel',
selModel:
{
mode: 'SINGLE'
},
viewConfig:
{
stripeRows: true
},
listeners: {
selectionchange: 'onSelectionChange',
show: 'onShow',
},
bind: {
store: '{RentalListStore}'
},
itemConfig: {
viewModel: true
},
plugins: {
pagingtoolbar: true
},
items: [
{
xtype: 'container',
docked: 'top',
items: [
{
docked: 'left',
xtype: 'button',
ui: 'decline',
itemId: 'returnRental',
text: 'Return Rental',
reference: 'btnReturnRental',
handler: 'onReturnClick',
disabled: true,
}
]
},
],
columns: [
{
text: "Customer",
flex: 1,
dataIndex: 'customer',
editor:
{
allowBlank: false
},
},
{
text: "Movie",
flex: 1,
dataIndex: 'movieRental',
editor:
{
allowBlank: false
},
},
{
text: "Date Rented",
flex: 1,
dataIndex: 'dateRented',
editor:
{
allowBlank: false
},
renderer: function (value, metaData, record) {
if (value != null && value != "") {
var dateRented = new Date(Date.parse(value))
return Ext.Date.format(dateRented, 'm/d/Y')
}
else {
return "";
}
}
},
{
text: "Date Returned",
flex: 1,
dataIndex: 'dateReturned',
editor:
{
allowBlank: false
},
renderer: function (value, metaData, record) {
if (value != null && value != "") {
var dateRented = new Date(Date.parse(value))
return Ext.Date.format(dateRented, 'm/d/Y')
}
else {
return "";
}
}
}
],

好的，您应该更深入地研究一下https://docs.sencha.com/extjs/7.3.1/modern/Ext.grid.Row.html#events
itemConfig: {
body: {
tpl: '<p>Hello World</p>',
listeners: {
beforeshow: sender => {
console.log(sender);
// Here you can tell your record to fetch data
}
}
}
}您可以随意使用小提琴https://fiddle.sencha.com/#fiddle/3bq5&view/editor
