use $index in component

Hi , i have a component <image-upload></image-upload> but i used it in v-for so i need to send the current index to component to use it when dispatch event , so how could i use something like <image-upload index="{{ $index }}"></image-upload> ?

First, define a prop called index inside <image-upload> that accepts a Number (you can give it another name if you’d like), Then, pass the index using <image-upload :index="index"></image-upload>

Please read more about components and passing props here: http://vuejs.org/guide/components.html#Passing-Data-with-Props

There is a section in the guide explaining this: http://vuejs.org/guide/list.html

<div v-for="(index, item) in items">
  {{ index }} {{ item.message }}
</div>

Please avoid using $index as it’s deprecated in 2.0
