Wxml file:

 
  
{Index }:{{ item: one }}
 Js file: Page ({items: [{one: "test1" ,}, {one: "test2"}]})

You can use wx: for-item to specify the variable name of the current element of the array.

You can use wx: for-index to specify the name of the variable under the array. The example is as follows:

Wxml file:

 
  
{Id }}:{ name. one }}
