Several ways for Vue to bind data

1. Use double curly brackets '{<strong><span style="font-size: 16px;">{}}</span></strong>' Give the data to the page

<template>

  <div class="mainBody">
      <h3>{{ msg }}</h3>
  </div>
</template>
<script>
export default {
   data(){
     return{
       msg:&#39;月落乌啼霜满天&#39;,
     }
}
}
</script>

2. Use the vue command

<template>

  <div class="mainBody">
       <Input v-model="msg"/>
  </div>
</template>
<script>
export default {
   data(){
     return{
       msg:&#39;月落乌啼霜满天&#39;
     }
}
}
</script>

The v-model is used here to bind the value of the input box to msg It can also be v-text v-html v-bind, etc.

3. Add ':' before the label attribute to bind

<template>

  <div class="mainBody">
    <CellGroup>
      <Cell :title="msg"/>
    </CellGroup>

  </div>
</template>
<script>
export default {
   data(){
     return{
       msg:&#39;月落乌啼霜满天&#39;,
     }
}
}
</script>

Bind the value of msg to the title of the cell through:title. If you forget to add ':' in front of the title attribute If so, the page display will become like this:

The value given to title is not the variable msg in data() but the string "msg"

4. Use `${}` to splice strings before data

<template>
<!-- 有时我们需要给要绑定的值拼接字符串，比如需要控制样式，拼接字符串时，那我们就需要这样写`${}`， -->
  <div class="mainBody">
    <CellGroup>
      <Cell :title="msg"/>
       <!-- 将‘江枫渔火对愁眠’单元格 的背景色绑定到 color:&#39;aqua&#39; -->
      <Cell title=&#39;江枫渔火对愁眠&#39; :style="`background-color: ${color}`"/>
       <!-- 将‘江枫渔火对愁眠’拼接在msg：&#39;月落乌啼霜满天&#39;后-->
      <Cell :title="`${msg}，江枫渔火对愁眠`" />
    </CellGroup>

  </div>
</template>
<script>
export default {
   data(){
     return{
       msg:&#39;月落乌啼霜满天&#39;,
       color:&#39;aqua&#39;
     }
}
}
</script>
