• Bind the click event

  	<view>
        <view> {
        
        {
        
        text}}</view>
        <button bindtap="changeText">按钮</button>
    	</view>
  

     Page({
        
        
     		data: {
        
        
     			text: "点击前"
     		},
     	
  		changeText: function () {
        
        
     		this.setData({
        
        
   				text: '点击后'
     			})
  		}
     })
  

• Input binding trigger event (two types) and input value

Look at the development documentation first to find the effect you want.

Example bindinput event
Effect: trigger once the content of the input box changes once

<input  bindinput='changeInput'  type='text' placeholder='请输入……'></input>

   changeInput(e){
    
    
     console.log(e.detail) 
   }
