Detailed explanation of the example of modifying the style of the clicking control on the WeChat applet

Now we need to implement the click control modification style in the WeChat applet, as follows:

The WeChat applet does not support direct manipulation of dom. To achieve this effect , we need to achieve it by setting data and then using two-way binding of data and interface.

Step one: Define the clicked and unclicked styles in wxss, as follows:

.service_selection .is_checked{ 
 border: 1px solid #FE0002 ; 
 color: #FE0002 ; 
 background: #fff; 
} 
.service_selection .normal{ 
 border: none; 
 color: #333; 
 background: #F0F1EC; 
}

Step 2: Set a flag in the data in the js file and call it isChecked. The default isChecked==false. As follows:

##

data: { 
  isChecked: false 
 }

Step 3: Bind the click event in the wxml file,

<view bindtap="serviceSelection"></view>

serviceSelection(){ 
  this.setData({ 
   isChecked:true 
  }) 
}

Step 4: Still perform data binding in the wxml file:

<view class="{{isChecked?&#39;is_checked&#39;:&#39;normal&#39;}}" bindtap="serviceSelection"></view>

{{isChecked?'is_checked':'normal'}}"
