#属性操作 #attributes manipulating avalon2与avalon1的属性操作虽然都是使用ms-attr，但用法完全不一样。 avalon2 and avalon1 use `ms-attr` to manipulate attributes,but way of useing is exactly the different. avalon1是这样操作属性的 avalon1 manipulate attributes like this ```

``` 其语法为 the grammer is ``` ms-attr-valueName="vmProp" ``` 有多少个属性就写多个ms-attr-。其中不能省略。此外，还存在ms-title, ms-alt，ms-src, ms-href, ms-selected, ms-checked等等缩略写法。但估计很少人知道，到底哪些属性可以缩写，哪些不能。 you have to write ms-attr-s as many as your wanting attributes.Besides,there are ms-title, ms-alt，ms-src, ms-href, ms-selected, ms-checked ETC abbreviated writing,but barely no people can know them all very well. avalon2从减轻用户的记忆出发，将你要操作的属性全部打包成一个对象，并规定，只能属性值才能使用@开头的vm属性。此外，avalon2不存在ms-title这样的缩略写法。 avalon2 redesign this directive from the angle of easy membering using a single object to contain all of you attributes,and set a rule: only attribute values can reference @mark started VM properties。Besides,there are ms-title liked abbreviated writings no more.

或者 or ```

``` attrObj为vm的一个对象属性，但这个不太常用。或者 attrObj is an object from VM properties.Or do it like this ```

``` ms-attr直接对应一个数组。这个灵感是来自ReactNative的style指令，它们可以通过数组，传入多个样式对象………… ms-attr useing a Array.This is come from ReactNative's style diretive,it can pass multiple parameters using an Array. 不过无论你怎么搞，最后你传的东西能保持avalon内部能将它变回一个对象就行了。 Anyway,just make sure avalon can transform your data to a object and it will work. 有时你的对象很长，需要换行，avalon2也是支持的，即便你写得像以下这么恶心，avalon2还是能认出来。 Sometimes you hava many attributes and you want to wrap it,avalon2 support wraps well even in such a gross example. ``` TODO supply a title

``` 但为了性能起见，ms-attr最好还是保持在一行吧。 for the sake of performance,please keep ms-attr short in a single line
