Solution

Step one:

First open the Wechat public platform, copy a primary button button code to the development platform, and then bind it to an event named "bindfirst". (of course, this bindfirst event needs to be defined in js, which will be defined in the following steps.)

The code is as follows:

Click and change.

Step 2:

Create a text for if condition tags to control, while defining an empty quantity in the js.

Assign a judge variable to the definition of the if condition to true (if the if condition tag is true, it displays text, if it is false, it does not display text), and then change the value of text in the event bound by button.

The code is as follows:

Wxml code

Click to change {{text}}

Js code

Page ({data: {text: [], judge:true,}, onLoad: function () {}, bindfirst:function () {var s=this.data.judgethis.setData ({text: "you clicked on me")})

Step 3:

Get the running results.

Text appears when you click once, and text is closed when you click the second time, because bindfirst uses changing the values of judge to true and false to change text.
