This article will explain in detail how to use v-bind in vue instructions. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. V-bind: you can bind some data to the attributes of an element. I am the p tag.

Let vm = new Vue ({el: "# app", data: {message: "I am the title value of the p tag", pId: "this is a random id"})

The output is:

2. V-bind: it can be simplified as: it is recommended to write the colon directly. I am the p tag.

Let vm = new Vue ({el: "# app", data: {message: "I am the title value of the p tag", pId: "this is a random id"})

The output is the same as the above result

3. V-bind: splicing of instruction expressions

If you want to implement the splicing of expressions, the concatenated string must be wrapped in quotation marks, otherwise it will be parsed as a variable.

Without quotation marks:

Error: [Vue warn]: Property or method "this is an additional id" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

Add quotation marks:

I'm the p tag.

Output result:
