How to output a two-dimensional array from a small program

When developing WeChat applet, two-dimensional arrays are needed to display information. So how to output and display the two-dimensional array? Let’s learn together.

How to output a two-dimensional array from a small program

1. First define a two-dimensional array

Page({  
    data:{
        mapData:[
            [{id:11},{id:12}],
            [{id:21},{id:22}],
            [{id:31},{id:32},{id:33}]
      ]
    }

})

2. Then use two layers of wx:for loops to output.

    
        
            
                {{item.id}}
