VUE实现Studio管理后台(十二):添加输入组合,复杂输入,输入框Input系列

这次的功能优点复杂,组件嵌套了很多次,自己表达能力毕竟有限,分享出来未必能讲明白。为了保持内容的连贯性,最终决定写一下。先看效果:

VUE实现Studio管理后台(十二):添加输入组合,复杂输入,输入框Input系列_第1张图片

关键点:
1、组件嵌套
手风琴式折叠组件,嵌套输入行,还嵌套输入行的组合(例子中的边框)

2、多角度重置
实时监测当前值跟缺省值是否一致,并提供重置功能。

3、不得不感叹,VUE强大!

比上次的代码增加了一个RxInputRowGroup.vue文件,在inputs目录下。基于slot实现,关键看这个代码就好:

<template>
  <div class="row-group">
    <div class="rx-input-row group-header" :class = "changed ? 'changed' :''">
      <div class="label" 
        :class="collapsed? 'collapsed' :''"
        @click="click"
      >
      {{label}}
      <div 
        v-if="changed"
        class="reset-button"
        @click="resetAll"
      >
        {{$t('widgets.reset')}}
      div>
      div>
      <div v-if="collapsed" class="group-value">
        <div 
          v-for="row in inputValue"
          v-if="row.value"
          class="value-label" 
        >
          {{row.value}}
          <span class="remove-button" @click="remove(row.value)">×span>
        div>
      div>
    div>
    <div v-if="!collapsed" class="row-group-body">
      <slot>slot>
    div>
  div>
template>

<script>

export default {
  name: 'RxInputRowGroup',
  props:{
    label:{ default:'' }, 
    value:{ default:[] }, 
  },
  data () {
    return {
      collapsed: true,
    }
  },
  computed:{
    changed(){
      for(var i in this.inputValue){
        let row = this.inputValue[i]
        if(row.value !== row.defaultValue){
          return true
        }
      }
      return false
    },

    inputValue: {
      get:function() {
        return this.value;
      },
      set:function(val) {
        this.$emit('input', val);
      },
    },
  },
  methods: {
    click(){
      this.collapsed = !this.collapsed
    },

    resetAll(event){
      for(var i in this.inputValue){
        this.inputValue[i].value = this.inputValue[i].defaultValue
      }
      event.stopPropagation()
    },

    remove(value){
      for(var i in this.inputValue){
        if(this.inputValue[i].value === value){
          this.inputValue[i].value = ''
        }
      }
    }
  },
}

<style>
.row-group .group-header .label{
  justify-content: space-between;
}

.row-group-body .rx-input-row .label{
  justify-content: center;
}
.row-group .group-header .label{
  position: relative;
}

.row-group .group-header .label::after{
  position: absolute;
  content: '';
  width: 0; 
  height: 0;
  top: 13px;
  right: 7px;
  border-width: 4px;
  border-style: solid;
  border-color: #c2c2c2 transparent transparent  transparent;
}

.row-group .group-header .label.collapsed::after{
  position: absolute;
  content: '';
  width: 0; 
  height: 0;
  top: 11px;
  right: 7px;

}

.group-value{
  display: flex;
  flex-flow: row;
  flex-wrap: wrap;
}

.group-value .value-label{
  display: flex;
  flex-flow: row;
  padding: 0 4px;

  justify-content: space-between;
  background: rgba(255,255,255,0.1);
  border-radius: 3px;
  margin: 1px;
}

.group-value .value-label .remove-button{
  margin-left:2px;
  cursor: pointer;
}

调用处代码:

<template>
  <CollapsibleItem class="option-item" @itemClick = "itemClick">
    <template #heading>
      {{inputValue.label}} 
      <div v-if="changed" class="reset-button" @click="resetAll">{{$t('widgets.reset')}}div>
    template>
    <template #body>
      <RxInputRowGroup 
        v-for="(row, i) in inputValue.rows" 
        v-if="row.isRowGroup"
        :key="i" 
        :label = "row.label"
        v-model = "row.rows"
      >
        <RxInputRow 
          v-for="(subRow, j) in row.rows" 
          :key="j" 
          :label = "subRow.label"
          :inputName = "subRow.inputName"
          :inputProps = "subRow.props"
          :defaultValue = "subRow.defaultValue"
          v-model = "subRow.value"
        >
        RxInputRow>

      RxInputRowGroup>
      <RxInputRow 
        v-else="row.isRowGroup"
        :key="i" 
        :label = "row.label"
        :inputName = "row.inputName"
        :inputProps = "row.props"
        :defaultValue = "row.defaultValue"
        v-model = "row.value"
      >
      RxInputRow>
    template>
  CollapsibleItem>
template>

累趴了,睡觉去了。
