Detailed explanation of the use of vue.js two-way binding

This time I will bring you a detailed explanation of the use of vue.js two-way binding. What are the precautions when using vue.js two-way binding? The following is a practical case, let's take a look.

One of the most important features of vue.js is two-way data binding, which is what we often call MVVM: Model-View-ViewModel. If we want to achieve two-way binding, of course we must first have "two-way". Here vue.js provides us with the View layer and the Model layer. The View layer is the code in HTML, and the Model layer is the Javascript code.

The starting and ending positions of the view layer and model layer are marked in the code.

In the view layer, we need to create a label to display the results of the program running in the model layer, and we need to add a class or ID to this label. In this example, I added an ID named app to a p label.

The model layer is the code we want to execute. First we need to create a new Vue object. The value corresponding to el in the object is the class name or ID name of the label we previously created in the view layer (this label is the vue object’s Scope), the value corresponding to data is another object. The key in this object is the code in "{{}}" in the view layer, and the value is the displayed result.
