示例

Example for el-table


<ElasticList v-model="value" :elTableProps="{}">
  <el-table-column label="姓名" prop="name"/>
  <el-table-column label="年龄" prop="age"/>
</ElasticList>

自定义操作列和添加按钮:


<ElasticList v-model="value">
  <el-table-column label="姓名" prop="name"/>
  <el-table-column label="年龄" prop="age"/>

  <!-- the last column for row operation -->
  <template #operation-column="{showDeleteButton,deleteRow}">
    <el-table-column label="操作" align="center">
      <template slot-scope="scope">

        <!-- other buttons -->
        <el-button>其他按钮</el-button>

        <!-- delete button -->
        <el-button
          type="danger"
          circle
          icon="el-icon-delete"
          @click="() => { deleteRow(scope.$index) }"
          v-show="showDeleteButton"
        />

      </template>
    </el-table-column>
  </template>

  <!-- add-row-trigger -->
  <template v-slot:add-row-trigger="{addRow}">
    <el-button @click="addRow">增加一行</el-button>
  </template>
</ElasticList>

Example for lists

reference-type array:


<el-form :model="form">
  <ElasticList v-model="form.list">
    <template v-slot="{item,index,showDeleteButton,deleteRow}">
      <div>

        <!-- delete button -->
        <i
          class="el-icon-circle-close"
          @click="deleteRow(index)"
          v-show="showDeleteButton"
        />

        <!-- editable elements -->
        <el-form-item label="名称" :prop="'list.' + index + '.name'">
          <el-input v-model="item.name"/>
        </el-form-item>
        <el-form-item label="排序" :prop="'list.' + index + '.sort'">
          <el-input-number v-model="item.sort"/>
        </el-form-item>

      </div>
    </template>
  </ElasticList>
</el-form>

value-type array:


<ElasticList v-model="value">
  <!--
    v-slot解构:
      index: {number} 行号
      item: {any} 数组第i项
      showDeleteButton: {boolean} 是否显示删除按钮
      deleteRow: {function} 删除行
  -->
  <template v-slot="{item,index,showDeleteButton,deleteRow}">
    <div>

      <!-- row contents -->
      <el-input v-model="value[index]"/>

      <!-- delete button -->
      <i v-show="showDeleteButton" class="el-icon-circle-close" @click="deleteRow(index)"/>

    </div>
  </template>

  <!-- add-row-trigger -->
  <template v-slot:add-row-trigger="{addRow}">
    <el-button @click="addRow">自定义增加行按钮</el-button>
  </template>
</ElasticList>

Props

参数名说明类型合法值默认值
v-model / value列表绑定值array
elTablePropsel-table 配置object
sortable是否开启拖拉拽排序booleantrue
disabled禁用模式下无法新增、删除、排序booleanfalse
count行数限制number, [number, number]
defaultRowValue新增行的默认值(item: any, index: number) => any{} / ''
...sortablejs 配置

elTableProps

默认值:

{
  border: true,
  fit: true,
  stripe: true,
  highlightCurrentRow: true,
}

配置方式:与默认值 进行混入

sortablejs 配置

默认值:

{
  filter: 'input,textarea,.el-rate',
  preventOnFilter: false,
  animation: 500,
}

配置方式:与默认值 进行混入

count

比如你想限制不能超过5行:

Vue.use(ElasticList, {
  count: 5
})

如果你还想限制不能低于2行:

Vue.use(ElasticList, {
  count: [2, 5]
})

defaultRowValue

如果没有指定,则会根据value的值推断使用 {}''

可以手动指定,支持 Function,Function 的返回值将作为新增项

组件内部会对其进行深拷贝

Vue.use(ElasticList, {
  defaultRowValue (i) {
    return i // i是新增的这一行的序号
  }
})

Slots

名称说明
add-row-trigger增加行的触发按钮
operation-columnel-table 最后一列(用于删除行等操作)
placeholdervalue 为空时的占位符
...el-table 所有 slot

Events

  • 支持 sortablejs 所有事件
  • 支持 el-table 所有事件

<ElasticList
  @select="onSelect"
  @sort="onSort"
>
</ElasticList>

拖动触发范围

默认是整行均可以拖动 如果你想要指定触发元素:


<ElasticList v-model="value" handle=".handle">
  <el-table-column type="index">
    <template slot-scope="scope">
      <span class="handle">
        {{ '# ' + (scope.$index + 1) }}
      </span>
    </template>
  </el-table-column>
  <el-table-column label="姓名" prop="name"/>
</ElasticList>

由于在输入框内拖动时,用户的用意往往是选中输入内容而不是拖动排序,所以默认在输入框内不触发排序(可配置)


value 监听

组件内不会监听非对象数组类型 value 的后续变化 如果 value 在初始化后需要修改,可使用以下方式:

为什么?

  • 如果数组元素被绑定到输入框之类的可以在界面上直接编辑的地方 每次输入都会触发重绘 导致无法连续输入

<template>
  <div>
    <ElasticList
      ref="elasticList"
    >
    </ElasticList>
  </div>
</template>

<script>
export default {
  created () {
    this.$POST().then(res => {
      this.$refs.elasticList.setValue(res.data)
    })
  },
}
</script>

或者


<template>
  <div>
    <ElasticList
      v-model="value"
      v-if="loading"
    >
    </ElasticList>
  </div>
</template>

<script>
export default {
  data () {
    return {
      value: [],
      loading: true
    }
  },
  created () {
    this.$POST()
    .then(res => {
      this.value = res.data
    })
    .finally(() => {
      this.loading = false
    })
  },
}
</script>
