Question

I use VueJs, i need to extract javascript variable to generate hidden fields.

But i need to set the name by the index of the variable.

I want to use zig-zag nami

Answer 1

To create input elements with dynamic names by index, you can use the + in a JS expression to concatenate:

<div v-for="(a,index) in test_template" class="row">            
  <input type="hidden" :name="'segment[' + index + '][nb]'" :value="a.nb">
</div>

Generates:

<input type="hidden" name="section[0][nb]" value="2">
<input type="hidden" name="section[1][nb]" value="1">
<input type="hidden" name="section[2][nb]" value="4">

See: https://vuejs.org/v2/guide/syntax.html#Using-JavaScript-Expressions

Answer 2

I ran across the same problem as you, and here is how i fixed it !

make a method like this in your vue-instance

getInputName(index, dataName){
      return "items["+index+"]["+dataName+"]";
    }    

then you can use it like this:

<input v-bind:name="getInputName(index, 'name')" type="text" v-model="item.name">
<input v-bind:name="getInputName(index, 'price')" type="text" v-model="item.price">

which will give you this post result:

"items" =>[
    0 =>[
      "name" => "test"
      "price" => "23"
    ],
    1 =>[
      "name" => "jakke"
      "price" => "99,2312"
    ]
]

And thats it...
