#单个slot

html:

<h3>#单个slot</h3>
<!-- 定义child01模板 -->
<template id="child01">
    <div>this is temp01 component!</div>
    <slot>
        如果没有分发内容，这里将会被显示
    </slot>
</template>
<div id="dr01">
    <child01></child01>
    <br /><br />
    <child01>
        <div>这里有新的内容01</div>
        <div>这里有新的内容02</div>
    </child01>
</div>

js:

//*********************************************************
//单个slot
var child01 = Vue.extend({
    template: "#child01",
});
var dr01 = new Vue({
    el: "#dr01",
    components: {
        "child01": child01
