Today, the editor will share with you the relevant knowledge points about how vue carries out in-depth monitoring. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

The specific methods are as follows:

1. First, create a new html project and introduce vue into the project

Import Vue from 'vue'

two。 After introducing vue, define a listening object in the project

Data () {

Return {

Obj: {

Name:' Star Moon'

Age:18

}

}

}

3. After the listening object is defined, use the watch method to listen on the entire object

Watch: {

Obj: {

Handler:function (newV,oldV) {

Console.log (newV)

}

}

}

4. Finally, after the listening event is set, add a deep attribute to the event and set it to true to achieve deep monitoring.

Watch: {

Obj: {

Deep:true

Handler:function (newV,oldV) {

Console.log (newV)

}

}

}
