实际生产环境使用的是jQuery.getJSON 调用，使用 setTimeout 的延时也复现出了同样的问题。为了容易复现问题，以下测试代码都用 setTimeout模拟问题。
<!DOCTYPE html> <html> <head> <title>延时加载数据</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="avalon.min.js"></script> </head> <body> <div ms-controller="box"> <p><h1>学校名：{{school.name}}</h1></p> <p>校长：{{school.uname}}</p> <p>成立日期：{{school.dateline*1000|date('yyyy-MM-dd')}}</p> <div ms-repeat="school.teacher"> <p>教师：{{el.name}} 加入时间：{{el.joindate*1000|date('yyyy-MM-dd')}}</p> </div> </div> <script> var model = avalon.define("box", function(vm) { vm.school = {}; }) //model.school = {"id":"1","name":"育才学校","uid":"1","uname":"杜甫","dateline":"1394091197","teacher":[{"joindate":"1399411951","name":"张三"},{"joindate":"1400901806","name":"李四"}]}; setTimeout('(function() {model.school = {"id":"1","name":"育才学校","uid":"1","uname":"杜甫","dateline":"1394091197","teacher":[{"joindate":"1399411951","name":"张三"},{"joindate":"1400901806","name":"李四"}]};})();', 100); avalon.scan(); </script> </body> </html>
以上使用 setTimeout 延时给 school 赋值，会出现avalon 只解析了第一级的数据，第二级的 school.teacher 数据并没有解析渲染。倘若不使用setTimeout 延时（使用注释行代码），直接将值赋给 model.school 对象，页面会得到正确解析渲染。
又测试了另一种情况：在延迟加载的数据完成后，通过触发事件来二次获取值：
<!DOCTYPE html> <html> <head> <title>延时加载数据</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="avalon.min.js"></script> </head> <body> <div ms-controller="box"> <p><h1>学校名：{{school.name}}</h1></p> <p>校长：{{school.uname}}</p> <p>成立日期：{{school.dateline*1000|date('yyyy-MM-dd')}}</p> <div ms-click="click">所有教师：{{x}}</div> </div> <script> var model = avalon.define("box", function(vm) { vm.school = {}; vm.x = ""; vm.click = function () { avalon.log(vm.school); for(var i=0; i<vm.school.teacher.length; i++) { vm.x += vm.school.teacher[i].name +'，'; } } }) setTimeout('(function() {model.school = {"id":"1","name":"育才学校","uid":"1","uname":"杜甫","dateline":"1394091197","teacher":[{"joindate":"1399411951","name":"张三"},{"joindate":"1400901806","name":"李四"}]};})();', 100); avalon.scan(); </script> </body> </html>
点击“所有教师”后，可正确获取所有值。
如何避免这样的情况？通过ajax延时获取值的场合较多，在作者的《avalon最佳实践》中要求数据对象最好扁平，我这边基本控制在不超过三级。现在看延时加载的数据到二级就会有问题。
The text was updated successfully, but these errors were encountered:
var arr = data.value.split(".") || [] if (arr.length > 1) { arr.pop() var v = vmodels[0],n = arr[0] if(v && v.hasOwnProperty(n) && v[n][subscribers]){ v[n][subscribers].push(data) } }
Sorry, something went wrong.
