<h2>绑定Html Class</h2>
<p>尽管可以用 Mustache 标签绑定 class,比如 class="{{ className }}",但是不推荐这种写法和 v-bind:class 混用。两者只能选其一!</p>
<div id="dr01">
<h4>#对象语法</h4>
<p>给v-bind:class一个对象,通过true、false动态切换class,isA为false,true,所以div的class为static、classB</p>
<!-- 下面是两种方式,一种直接在v-bind:class里面展示对象,另外一种,在data里面添加classObj属性,在v-bind:class里面赋值classObj对象 -->
<div v-bind:class="{static:isStatic,classA:isA,classB:isB}">1、对象语法class test</div>
<div v-bind:class="classObj">2、对象语法another class attribute bind</div>
</div>
<hr />
<div id="dr02">
<h4>#数组语法</h4>
<div v-bind:class='["classC","classD","classE","classF"]'>1、数组语法,直接添加"className",不能动态更改,与class="classC classD classE classF"保持一致</div>
<div v-bind:class='["classC","classD",isE?"classE":"","classF"]'>1、数组语法,直接添加"className",里面使用了三元表达式</div>
<div v-bind:class='[drClassC,drClassD,drClassE,drClassF]'>2、数组语法,数组的元素在data里面有定义,挨个赋值className</div>
<div v-bind:class='[drClassC,drClassD,drClassE,isF?drClassF:""]'>3、数组语法,里面使用了三元表达式</div>
<hr />
<h4>#对象语法、数组语法混合使用</h4>
<div>
<p>在 1.0.19+ 中,可以在数组语法中使用对象语法:{{cHtml}}</p>
<span>classA: data定义(三元表达式), classB:直接引用(三元表达式),classC:data引用,classD:直接引用,EFGH是对象属性,所以不论属性名称是否有引号,只要属性值在data里面定义的是true,引用的都是属性名,false不引用</span>
<div v-bind:class='[isA?drClassA:"",isB?"classB":"",drClassC,"classD",{"classE":isE,drClassF:isF,"classG":isG,drClassH:isH}]'>

<h2>绑定内联样式</h2>
<div id="dr03">
<h4>#对象语法</h4>
<div v-bind:style="{color:activeColor,fontSize:activeFontSize}">1、对象语法简单测试</div>
<div v-bind:style="styleObj">2、对象语法(在data下定义)</div>
</div>
<div id="dr04">
<h4>#数组语法</h4>
<div v-bind:style="[{color:'blue',fontSize:'15px'},{fontStyle:'italic',backgroundColor:'lightgoldenrodyellow'}]">2、数组语法简单测试</div>
<div v-bind:style="[styleObj01,styleObj02]">2、数组语法简单测试</div>
