component application components

This article mainly introduces the application scenarios of Vue's built-in component components. Now I will share it with you and give you a reference.

Official instructions

Render a "meta component" as a dynamic component. Which component is rendered depends on the value of is.

<!-- 动态组件由 vm 实例的属性值 `componentId` 控制 -->
<component :is="componentId"></component>

Dynamic components

Built-in component component

Scenario

Here is a business scenario to illustrate the application of Vue's built-in component components. As shown in the figure, the classic registration page is shown here. Registration is divided into email registration and mobile phone registration. There is a label at the top of the pop-up window to switch the registration type. In the middle is the registration form information. Email registration and mobile phone registration have different form contents. The bottom is Register button and other actions. After analysis, the mobile phone registration interface and the email registration interface are the same except for the inconsistent content of the form in the middle.

#In actual project code design, there are some feasible solutions to ensure reusability and maintainability. Here we use vue's built-in component component to achieve this.

Core code implementation

When the top tab is switched, the type value changes, and the corresponding form components also change

<template>
 <p>
	<a href="javascript:;" rel="external nofollow" rel="external nofollow" @click.prevent="handleCloseBtnClick"></a>
	<p>
	 <h3>新用户注册</h3>
	 <p>
		<span :class="{active: type === &#39;mobileForm&#39;}" @click="type = mobileForm">手机注册</span>
		<span :class="{active: type === &#39;emailForm&#39;}" @click="type = emailForm">邮箱注册</span>
	 </p>
	</p>
	<component :is="type" ref="form">
	 <button @click="handleRegisterBtnClick">注册</button>
	 <p ><span ><span>注册视为同意</span><a> 《法律条款和隐私说明》</a></span></p>
	 <p><span>已有账号<a href="javascript:;" rel="external nofollow" rel="external nofollow" @click.prevent="handleLoginBtnClick">直接登入>></a></span></p>
	</component>
 </p>
</template>
<script>
 export default {
 	methods: {
		handleRegisterBtnClick () {
		 	this.$refs.form.validateData().then(() => {
				this.$refs.form.getFormData()
			})
		 }
	}
 }
</script>

mixins mixing

When using Vue’s built-in component components, generally the components that are actually rendered have certain commonalities, such as the same attributes, the same method or the same initialization and destruction process. For example, in the current scenario, both the email form and the mobile phone form have a verification method (validateData) and a method for obtaining form data (getFormData). In this case, you can use the mixing function provided by vue. Further abstraction mixins.js

export default {
 methods: {
  validateData() {
   return Promise.resolve()
  },
  getFormData() {
   return {}
  }
 }
}
Copy after login

email-form.vue

<script>
import minx from &#39;./mixins&#39;
export default {
 mixins: [mixins],
 methods: {
  getFormData() {
   return { email: &#39;example@example.com&#39; }
  }
 }
}
</script>
Copy after login

If you have custom requirements, you can override the methods in mixins.

Application of tables

In management background projects, tables are often used. We hope that the td of the table is text, progress bar, checkbox, etc., and we hope that it can be rendered by passing a json configuration. Using vue's built-in component component can play a great role.

For example, how to use a table like this

<template>
 <vue-table ref="table" :columns="columns" :datum="datum"></vue-table>
</template>
<script>
export default {
  data () {
   return {
    columns: [
     { title: &#39;ID&#39;, width: &#39;30&#39;, dataKey: &#39;id&#39; },
     { title: &#39;进度组件&#39;, dataKey: &#39;progress&#39;, render: { type: &#39;progress2&#39;, max: 100, precision: 2 } }
    ],
    datum: [{ id: &#39;1&#39;, name: &#39;进度0&#39;, progress: 10 }]
   }
  }
 }
</script>
Copy after login

The implementation of using component in table

<td v-for="column of columns">
	<component :is="`${TYPE_PRE}${columns.render.type}`" :row-data="rowData" :params="columns.render"></component>
</td>
Copy after login

Application of forms

In management background projects, forms are often used. We also hope that one of the items in the form is a text box, a drop-down box, and a time selection. Box, rich text, etc., and hope that it can be rendered by passing a json configuration. Vue's built-in component component can still realize such a beautiful vision.

For example, how to use a form like this

<template>
  <c-form :cells="cells" ref="form">
   <button class="button is-primary" :class="{ &#39;is-disabled&#39;: isSubmitBtnDisabled }" @click.prevent="submit">提交</button>
  </c-form>
</template>
<script>
  export default {
  computed: {
   cells () {
    return [
     {
      field: &#39;name&#39;,
      label: &#39;名称&#39;,
      type: &#39;textfield&#39;,
      attrs: { placeholder: &#39;名称&#39; },
      validate: { required: { message: &#39;请输入名称&#39;} }
     },
     {
      field: &#39;enable&#39;,
      label: &#39;启用标志&#39;,
      type: &#39;dropdown&#39;,
      extra: {options: [{ label: &#39;启用&#39;, value: 1 }, { label: &#39;禁用&#39;, value: 2 }] }
     }
    ]
   }
  }
 }
</script>
Copy after login

The implementation of using component in form

<form>
 <c-form-cell v-for="cell of cellList" :key="cell.field" :field="cell.field">
  <component
	 :is="`${TYPE_PRE}${cell.type}`"
	 :field="cell.field"
	 :attrs="cell.attrs"
	 :extra="cell.extra"
	 :validate="cell.validate"
	 :cells="cell.cells">
  </component>
 </c-form-cell>
</form>
Copy after login

The above is I compiled it for everyone, I hope it will be helpful to everyone in the future.

Angular components and their display properties: understanding non-block default values Angular components and their display properties: understanding non-block default values Mar 15, 2024 pm 04:51 PM

The default display behavior for components in the Angular framework is not for block-level elements. This design choice promotes encapsulation of component styles and encourages developers to consciously define how each component is displayed. By explicitly setting the CSS property display, the display of Angular components can be fully controlled to achieve the desired layout and responsiveness.
