条件渲染:
1.v-if:
写法:
1).v-if="表达式"
2).v-else-if="表达式"
3).v-else="表达式"
适用于:
切换频率较低的场景
特点:
不展示的DOM元素直接被移除
注意:
v-if可以和v-else,v-else-if一起使用, 但要求结构不能被"打断"
2.v-show
写法:
v-show="表达式"
适用于:
切换频率较高的场景
特点:
不展示的DOM元素未被移除,仅仅是使用样式隐藏掉
3.备注:
1).使用v-if时, 元素可能无法获取到, 而使用v-show一定可以获取到
2).template不会改变结构, 可以和v-if配合使用批量设置条件渲染
