样式操作:ms-css-样式名=“样式值”,ms-class
ms-css-width="prop"(自动补px)
ms-css-height="{{prop}}%"
ms-css-color="prop"
ms-css-background-color="prop"
ms-css-font-size="{{prop}}px"
注:样式值不能加入css hack和!important
事件绑定:

多重事件绑定:遵循后绑定的事件先执行的规则。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>multi-event-2</title>
<script src="avalon.js"></script>
<script>
var vm = avalon.define({
$id: "xxx",
fn: function() {
console.log("111111");
},
fn1: function() {
console.log("222222");
},
fn2: function() {
console.log("333333");
}
}); </script>
</head>
<body>
<div ms-controller="xxx" style="width: 100px; height: 100px; background: red;" ms-on-mouseenter-3="fn" ms-on-mouseenter-2="fn2" ms-on-mouseenter-1="fn1"></div>
</body>
</html>
循环操作:数组遍历:ms-repeat-->{{el}},ms-each-->{{el}};对象遍历:ms-repeat-->{{$key}},{{$val}},ms-with-->
{{$key}},{{$val}}
注:对ms-repeat而言,ms-repeat-*-->{{*}},如外层ms-repeat-elem,内层可通过{{elem}}访问当前元素
两者区别:ms-repeat绑定在子元素上,ms-each绑定在父元素上,ms-with绑定在父元素上

循环显示数组元素的临时变量:
el:任何类型,引用着当前循环的元素
$index:Number,当前循环元素对应的索引值
$first:Boolean,当前循环元素是否为数组的第一个元素
$last:Boolean,当前循环元素是否为数组的最后一个元素
$remove:Function,用于从数组中删除当前循环
$outer: Object,用于内层循环访问外层循环的变量,内层访问外层{{$outer.$index}}
循环显示对象的临时变量:
$key:String,当前循环中的键名
$val:任何类型,当前循环中的键值
$outer:Object,用于内层循环访问外层循环的变量
数据的更新:
对象的更新:obj.key = newVal
数组的更新:简单值更新:arr.set(index, newVal)
对象值更新:arr[i].key = newVal

回调绑定属性:
data-repeat-rendered 当前操作名(add,del,move,append,clear),用ms-repeate绑定,当监控数组发生添加、删除、重排等操作时触发
data-with-sorted 原对象的所有键名构成数组,用ms-repeat,ms-with绑定,赶在对象渲染之前触发,要求输出一个字符串数组,对象的键值对会根据它一次输出
data-with-rendered 当前操作名(append),用ms-with绑定,当前目标对象输出页面后触发
data-each-rendered 当前操作名(add,del,move),用ms-each绑定,当监控数组发生添加、删除、重排等操作时触发
数组长度与循环分支判断:
获取数组长度:使用size方法,不使用length属性
循环分支判断:使用ms-if-loop判定属性,不能使用ms-if,因为ms-if先于ms-repeat执行的
监控数组方法:
push,pushAll,shift,unshift,pop,clice,remove,removeAt,removeAll,clear,ensure,sort,reverse,set
用法:vm.array.push或vm.array[push]
avalon模板类型:
嵌入到页面的模板:ms-include="expr"
独立成子页面的模板:ms-include-src="expr"
