How to use the dynamic form generator in uniapp

The dynamic form generator is a tool that can dynamically generate forms according to user needs. In uniapp, we can use the dynamic form generator to quickly build flexible and scalable form pages to improve development efficiency. This article will introduce how to use the dynamic form builder in uniapp, with code examples.

1. Introduce the dynamic form generator

Before using the dynamic form generator, you need to introduce the relevant dependent libraries. In the project root directory of uniapp, find the package.json file and add the relevant dependent libraries in dependencies, for example:

"dependencies": { "form-making": "^1.6.8", ... }

Then in the page where you need to use the dynamic form generator, use npm or yarn to install the dependent libraries. ：

npm install form-making --save

or

yarn add form-making

2. Create a dynamic form page

Create a new page in uniapp, such as DynamicForm.vue, and then introduce the relevant components of the dynamic form generator ：

In the above example, we created a simple form page and used the form-making component to render the dynamic form. The formData array contains the configuration data of the form, such as the type, label, and key name of the input box. The formValue object is used to store the value of the form input.

3. Use the dynamic form generator

In the dynamic form page, we can dynamically add, remove, and modify form items according to needs. For example, add a button to the page and dynamically add an input box when the button is clicked:

In the sample code, we added a button and bound the addInput method to the button's click event. When the button is clicked, the configuration data of an input box is dynamically added to the formData array.

4. Submit form data

In actual development, we usually need to submit the form data to the server. You can add a submit button to the form page and bind a method to the button's click event, in which the form data is sent to the server.

In the sample code, we bind the submitForm method to the submit button and print the form data to the console in this method. In actual development, form data can be sent to the server as needed.

Summary

Through the above steps, we can use the dynamic form generator in uniapp to quickly build a flexible and scalable form page. Through dynamic configuration data, we can realize the function of dynamically adding, removing, and modifying form items to improve development efficiency. I hope the introduction in this article will be helpful to everyone in using the dynamic form generator in uniapp.
