avalon2的ms-css的變革思路與ms-attr同樣，將多個操做合併成到一個對象裏面處理，所以沒有ms-css-name="value"，只有ms-css="Object"或ms-css="Array".css

注意，當你用對象字面量的方式傳參時，注意存在－號的鍵名要用「」號括起來。html

<div ms-css="{font-size: @fs}"></div>

這個會報錯.正確寫法是如下兩種git

<div ms-css="{fontSize: @fs}"></div>

<div ms-css="{'font-size': @fs}"></div>

在avalon1.*系列，容許你在屬性值中加入插值表達式，如github

ms-css-width=」prop」(會自動補px)，ms-css-height=」{{prop}}%」, ms-css-color=」prop」, ms-css-background-color=」prop」, ms-css-font-size=」{{prop}}pxide

這些在avalon2中都不支持，它頂多幫你的樣式加上廠商前綴，駝峯化，對數字屬性加上px。學習

<div ms-css="[{width:@width, height: @height+'px', color: @color, backgroundColor:@bg}, @otherStyleObject, @thirdStyleObject]"></div>

            var vm = avalon.define({
                $id: "test",
                background: "red"
            })
        </script>
    </head>
    <body>
        <div ms-controller="test">
            <div style="width:200px; height:50px" 
                 ms-css="{background: @background}">
            </div>
            <select ms-duplex="@background">
                <option value="red">紅</option>
                <option value="yellow">黃</option>
                <option value="green">綠</option>

咱們來看另外一個動畫效果：動畫

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <script src="./dist/avalon.js" ></script>
        <script>
            var vm = avalon.define({
                $id: "test",
                percent: 0
            })
            var a = true
            var id = setInterval(function() {
                if (a) {
                    if (vm.percent < 100) {
                        vm.percent++
                    } else {
                        a = false
                    }
                } else {
                    if (vm.percent > 0) {
                        vm.percent--
                    } else {
                        a = true
                    }
                }
            }, 100)
        </script>
        <style>
            .handerx{
                width:20px;
                height:20px;
                position: absolute;
                color:#fff;
                background: #000;
            }
            .sliderx{
                width:100%;
                height:20px;
                position: relative;
            }
            .body{
                padding:40px;
            }
        </style>
    </head>
    <body ms-controller="test" class="body">
        <div class="slider" style="background:red;">
            <div class="handerx" ms-css="{left: @percent+'%'}" >{{ @percent }}</div>
            <div style="background: greenyellow;height:20px" ms-css="{width:@percent+'%'}"></div>
        </div>
        <div class="sliderx" style="background:#d2d2d2;">
            <div style="background: #2FECDC;height:20px" ms-css="{width:100-@percent+'%'}"></div>
        </div>
    </body>
</html>

最後看一下與ms-duplex結合使用的例子ui

<html>
    <head>
        <title>ms-css</title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge" /> 
        <script src="./dist/avalon.js" ></script>
        <script>
            var vm = avalon.define({
                $id: "test",
                w: 100,
                h: 100,
                click: function () {
                    vm.w = vm.w + 10;
                    vm.h = vm.h + 10;
                }
            })

        </script>
    </head>
    <body>
        <div ms-controller="test">
            <div style=" background: #a9ea00;" ms-css='{width:@w,height:@h}' ms-click="@click"></div>
            <p>{{ @w }} x {{ @h }}</p>
            <!--change過濾器至關於原來data-duplex-event='change'-->
            <p>W: <input type="text" ms-duplex-number="@w|change" /></p>
            <p>H: <input type="text" ms-duplex-number="@h" /></p>
        </div>
    </body>
