WeChat Mini Programs clicks the control to modify the style example in detail.

Now you need to implement the click control to modify the style in WeChat Mini Programs, as follows:

Direct manipulation of dom is not supported in WeChat Mini Programs. To achieve this effect, we need to set up data, and then use the two-way binding of data and interface to achieve it.

Step 1: define 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 data in the js file, calling it isChecked, the default isChecked==false. As follows:

Data: {isChecked: false}

Step 3: bind the click event in the wxml file

Implement this method in the js file and click on it to set the isChecked==true. As follows:

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

Step 4: still bind the data in the wxml file:

The point is that this code

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

This is a ternary operator. When isChecked==true, add the style of is_checked to class, and use the style of normal when it is flase. The implementation of this is similar to the syntax for php control style class names.
