I am having the same issue. Trying to access array with dynamic index arrayList[index] (index from aura:iteration), but Salesforce doesn't support that.

Does anyone know how to do this?

Peace of code:

<aura:attribute name="iterList"             type="List" />
<aura:attribute name="phones"               type="String[]" />

<aura:iteration items="{! v.iterList }" var="val" indexVar="index">
    //some code here

            <ui:inputPhone label="{! v.labelName }" aura:id="phone" value="{! v.phones[index] }" class="form-control"/> 

   //some code here


Result: [ERROR]: expecting a positive integer, found 'index' at column 11 of expression: v.phones[index]

  • looks like you will have to manipulate in your Javascript controller .How about breaking this only inputPhone to another component and use an attribute or use dynamic $A.createComponents Aug 24, 2016 at 6:04
  • yeah, that's good idea, but not in my particular case. I've decided to change logic a little bit and iterate over phones array using var, Thanks anyway. Aug 24, 2016 at 6:16

    Still wondering , how we can iterate simultaneously over two arrays? Or there is no possible way to do it and we should use dynamic creation of the components in js controller. Aug 24, 2016 at 14:43
  • For this, we can create an array of both the arrays like arr1, arr2, then iterate over 1 and push both in the array(new object with both arrays values for that index and so on) var finalArray = [];for(var i = 0; i < arr1.length; i++){ finalArray.push({arr1: arr1[i]m arr2: arr2[i]}) } and finally iterate over finalArray and access both the array values with arr1 & arr2 inside the aura:iteration.

I needed something similar so I used HTML input components instead of Ui:input components and used the data-selected-Index attribute for storing the index value


The easiest option is to create a component to display data within your iteration that would display whatever data you want.


You can manipulate the incoming json stored in the attribute iterList. Since in the attribute Phones, you have related values at the same index, you can add the phone value to the iterList attribute by creating a key value pair in the json.

For example, lets say your iterList structure is: [{"Name":"John","Age":"26"},{"Name":"Marie","Age":"21"},.......]

And your phones attribute is: ["12345678","87654532","98232233",...].

Then, we can write the following code to map the phones to the corresponding value in iterList:

var iterList=component.get("v.iterList");
var phones=component.get("v.phones");
for(var i in iterList){

Now, you will have to modify your cmp file code as follows:

<aura:iteration items="{! v.iterList }" var="val" indexVar="index">
    //some code here

<ui:inputPhone label="{! v.labelName }" aura:id="phone" value="{!val.Phone}" class="form-control"/> 

   //some code here
