Webix使用Ajax+JSON

//查询车辆在线
function queryOnline(){
	if(!$$('form1').validate()){
		exit;
	}
	var obj = $$('form1').getValues();
	webix.message("<pre>" + JSON.stringify(obj,1)+"</pre>");
	
	var url = obj.url;
	var commno = obj.commno;
	G_commno = commno;
	
	var jsondata = {"commno": commno};
	webix.ajax().header({
		"Content-type":"application/json"
	}).post(url,jsondata).then(function(data){
		$$("form1").setValues({
			url: url,commno: commno,result: JSON.stringify(data.json())
		})
	}).fail(function(xhr){
		var response = JSON.parse(xhr.response);
		webix.message({type:"error",text: response.error.message});				
	});		
}
