所以我们有时候,不需要这外层的 div 所以我们可以采用上面 的方法,在 <template>标签上使用 v-for来循环。或者这样写: <template> 测试{{index}} </template>
v-for使用时的报错 Errors compiling template: Invalid v-for expression: (item,index)in poinstionData 因为v-for 带索引时,括号与in之间必须加空格,否则就会报如下如的错误。 正确如下:in与括号之间必须要有空格

当用v-data-table显示记录表时,如果item.isActive是真的,我想显示一个徽章。为此,我在中循环使用。每当我为<template>标签提供密钥时,我就会得到'<template v-for>' cannot be keyed. Place the key on real elements instead。当我试图键入时,我得到了<template v-for> key should be placed on the <...

However the compiler can only check the current template for used properties. So in first example $item.index and $item.iteration are created, but not in the second. There is now a new attribute 'properties' which does force compilation of properties which might be used outside the current ...
