我是 extjs 的新手，我面临一个问题，我真的不明白为什么它不起作用。我试图从我的网格和填充网格的数据库中删除一行，但我的客户说我的服务器上没有删除（抱歉英语不好）
这是我的代码：
店铺：
Ext.define('LU.store.Audios', {
extend: 'Ext.data.Store',
autoLoad: true,
autoSync: true,
model: 'LU.model.Audio',
proxy: {
type: 'rest',
api: {
create: 'http://localhost:3000/upload',
read: 'http://localhost:3000/list',
update: 'http://localhost:3000/update',
destroy: 'http://localhost:3000/delete'
},
reader: {
type: 'json',
root: 'audios',
totalProperty : 'total',
successProperty: 'success'
},
writer: {
type: 'json'
}
}
});
模型 ：
Ext.define('LU.model.Audio', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', type: 'int'},
{ name: 'name', type: 'string'},
{ name: 'path', type: 'string'}
],
});
看法 ：
Ext.define('LU.view.Main', {
extend: 'Ext.panel.Panel',
alias: 'widget.mainview',
id: 'main',
initComponent: function() {
this.items = [{
}, {
xtype: 'grid',
title: 'Audio liste',
store: 'Audios',
id: 'mygrid',
columns: [
{text: 'Dateiname', dataIndex: 'name'},
{text: 'Dateipfad', dataIndex: 'path'}
],
listeners : {
afterrender : function (grid) {
grid.addDocked({
xtype: 'toolbar',
dock: 'top',
items: [{
text: 'Delete',
action: 'delete'
}, {
text: 'Download'
}]
});
}
},
}
];
this.callParent(arguments);
}
});
和控制器：
Ext.define('LU.controller.MainController', {
extend: 'Ext.app.Controller',
views: ['Main'],
stores: ['Audios'],
models: ['Audio'],
init: function() {
this.control({
'mainview button[action=delete]': {
click: this.delete
}
});
},
delete: function () {
var grid = Ext.getCmp('mygrid');
var row = grid.getSelectionModel().getSelection();
Ext.getStore("Audios").remove(row);
},
});
和服务器：
var express = require ('express');
var app = express();
var fs = require('fs');
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'root',
});
connection.connect();
connection.query('USE diktierserver');
app.use(express.bodyParser());
app.all('*', function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'HEAD, GET, POST, PUT, DELETE, OPTIONS');
res.header('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, Origin, Accept');
res.header('Access-Control-Allow-Credentials', 'true');
if(req.method.toLowerCase()==='options'){
res.send(200);
}else{
next();
}
});
app.delete('/delete', function (req,res) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Content-Type','text/plain; charset=UTF8');
console.log(req);
var id = req.params.id;
connection.query('DELETE FROM audio WHERE id = ' + id +'', function (err,result) {
if (err) throw err;
console.log(name + 'deleted');
res.status(200).send(JSON.stringify());
});
});
app.listen(3000);
