el-form-renderer

Form renderer is based on element-ui. It inherits all of the element's attribute definitions completely and extends them briefly. So users can render a complete element form by using a piece of preset data.

Quick start

// Step1: Make sure you have properly installed element-ui and used it correctly.

// Step2: Install
yarn add el-form-renderer

// Step3: In the .vue file that needs the renderer
<template>
  <el-form-renderer :content="content"></el-form-renderer>
</template>

<script>
import ElFormRenderer from 'el-form-renderer'

export default {
  components: {
    ElFormRenderer
  }
}
</script>

Props

• Support all attributes on el-form.

• disabled [Boolean] Set true to disable all atomic forms. If the element-ui version is still below 2.1.0, it is still compatible.

• content [ObjectArray] Define the contents of the form, each Object represents an atomic form (such as el-input, el-select, ...), All attributes on the el-form-item are declared here, and attributes on the el-input etc. are declared on the $el attribute. There are other attributes on the Object such as: $id, $type, $default，$enableWhen[optional], $options[optional], $attrs[optional].

// content example
[
  {
    $id: "form1", // Each atomic form uses an id to store its value, be careful not to repeat
    $type: "input", // Type, all the form types provided by element, like el-xxx
    $enableWhen: { form2: 'beijing' }, // Optional attribute, which means that the this atomic form will display when form2's value is beijing
    $attrs: { 'data-name': 'form1' }, // Optional attribute, wording follows the Render function specification of Vue
    label: "Input", // A property on the el-form-item
    $default: "default value",
    rules: [{ required: true, message: 'Please enter the name of the activity name', trigger: 'blur' }] // A property on the el-form-item
  }, {
    $id: "form2",
    $type: "select",
    label: "Select",
    // $el: Used to define the properties of a specific atomic form (el-select in this case)
    $el: {
      placeholder: "Please select your zone"
    },
    // $options: Each atomic form with Selection Capabilities use this to define options. (such as: select, radio-group, radio-button, checkbox-group, checkbox-button, etc.)
    $options: [{
      label: 'Zone one',
      value: 'shanghai'
    }, {
      label: 'Zone two',
      value: 'beijing'
    }]
  }
]

In addition, we added an optional value to the $type attribute: group, which can be used to create more complex data types:

// This example will get the object data structure:
// group1: {
//   input1: '',
//   input2: ''
// }
{
  $id: "group1", // Follow the principle of the same level of ID is not repeated, essentially equivalent to the object's key
  $type: "group",
  label: "object data example",
  $items: [{
    $id: "input1",
    $type: "input",
    label: "input1",
    $default: "default value"
  }, {
    $id: "input2",
    $type: "input",
    label: "input2",
    $default: "default value",
  }]
}
