Ext.define('Ext.ux.data.proxy.Ajax', { extend: 'Ext.data.proxy.Ajax', async:true, doRequest: function(operation, callback, scope) { var writer = this.getWriter(), request = this.buildRequest(operation); if (operation.allowWrite()) { request = writer.write(request); } Ext.apply(request, { async : this.async, binary : this.binary, headers : this.headers, timeout : this.timeout, scope : this, callback : this.createRequestCallback(request, operation, callback, scope), method : this.getMethod(request), disableCaching: false }); Ext.Ajax.request(request); return request; } });
使用的时候:
proxy: Ext.create("Ext.ux.data.proxy.Ajax",{ async:false, url:"data/SystemMenus.json", reader: { type: 'json', root: 'children', idProperty: 'id' } })
