1 实现效果

2 应用

2.1 父组件调用模板

<template>
<Row>
  <Form label-position="right" :label-width="80">
    <Col span="24" v-for="(conditionItem, key, index) in otherCondition.conditionItems" :key="index">
      <FormItem>
        <Select
          v-model="conditionItem.id"
          placeholder="请选择查询类型..."
          @on-change="val=>{ conditionItemChange(val, conditionItem, otherCondition.otherConditionselect) }"
          style="width:140px; float:left; margin-right:8px"
        >
          <Option
            v-for="optionItem in otherCondition.otherConditionselect"
            :value="optionItem.id"
            :key="optionItem.id"
          >{{ optionItem.name }}</Option>
        </Select>
        <div class="conditionItemDetails" style="width:400px; float:left;">
          <form-type :conditionItem="conditionItem"></form-type>
        </div>
        <span class="j-sm-close-btn ml-5" @click.stop.prevent="deletecondition(key)">
          <Icon type="md-close"></Icon>
        </span>
        <div class="clearfix"></div>
      </FormItem>
    </Col>
    <Col :xs="24" :sm="12" :md="8" :lg="5">
      <FormItem>
        <Button type="dashed" long icon="md-add" @click="addOtherCondition">添加筛选条件</Button>
      </FormItem>
    </Col>
  </Form>
</Row>
</template>

2.2 父组件相关js

属性名 内容 可选项
id 字段名
name 昵称
type 类型 text- 单选文本框; texts- 多选文本框; textarea- 多行文本框;
select- 单选下拉框; selects- 多选下拉框;
time- 时间节点; times- 时间段
value 改字段的值 数字-null; 字符串-''; 数组-[]
options 下拉选项

1. 查询条件

otherCondition: {
  conditionItems: [],
  otherConditionselect: [
    { id: 'level', name: '角色等级', type: 'texts' },
    { id: 'create_dt', name: '注册时间', type: 'times' },
    { id: 'online', name: '是否在线', type: 'select', options: [{value: 0, label: '否'}, {value: 1, label: '是'}]},
    { id: 'login_ip', name: '登录IP', type: 'text', value: '' },
    { id: 'platform', name: '登录渠道商', type: 'cascader', options: []}
  ]
}

2. 获取下拉数据

async getConditionPlatformMap() {
  try {
    let { data: result } = await this.$axios.get(`${this.url}?id=${this.id}`)
    if(result.code === 1) {
      let data = result.data
      data.data_list.forEach(item => {
        item.children.unshift({ value: 'all', label: '全部' })
      })
      let otherSelect = this.otherCondition.otherConditionselect
      otherSelect.forEach(item => {
        if(item.id === 'platform') {
          item.options = data.data_list
        }
      })
      otherSelect = null
    } else {
      this.$Message.warning(result.msg)
    }
  } catch(e) {
    this.$Message.warning('操作失败')
  }
}

tip: forEach 用来修改原数组;map 会返回一个新数组

3. 其他相关方法

  • 添加条件
addOtherCondition () {
  this.otherCondition.conditionItems.push({ id: '' });
}
  • 删除条件
deletecondition(key) {
  this.otherCondition.conditionItems.splice(key, 1);
}
  • 选择条件
conditionItemChange (val, item, otherConditionselect) {
  for (var i = 0; i < otherConditionselect.length; i++) {
    if (val === otherConditionselect[i].id) {
      if (['texts', 'selects', 'times', 'cascader'].indexOf(otherConditionselect[i].type) !== -1) {
        this.$set(item, 'value', []);
      } else {
        this.$set(item, 'value', null);
      }
      item['formType'] = otherConditionselect[i];
    }
  }
}
  • 初始化其他查询条件的标识key
setOtherConditionName (datas) {
  let conditionSelect = this.otherCondition.otherConditionselect;
  for (var i = 0; i < conditionSelect.length; i++) {
    datas[conditionSelect[i].id] = [];
  }
  conditionSelect = null;
}
  • 获取其他查询条件
getOtherCondition (datas) {
  let conditionItems = this.otherCondition.conditionItems
  for(var i = 0; i < conditionItems.length; i++) {
    let value = conditionItems[i].value
    let type = conditionItems[i].formType.type
    let itemId = conditionItems[i]['id']
    if(
      String(value) === 'undefined' ||
      String(value) === 'null' ||
      String(value) === '' ||
      String(value) === '[]'
    ) {
      // 选了查询类型但是没选值,不做处理
      continue
    }
    if(['texts', 'selects', 'times', 'cascader'].indexOf(type) !== -1 && value.length <= 1) {
      // 选了 'texts', 'selects', 'times', 'cascader' 但是没选值或只选一个值,不做处理
      continue
    }
    if(['texts', 'selects', 'cascader'].indexOf(type) !== -1) {
      let newdata = value[1] == 'all' ? value[0] + ',' : value[0] + ',' + value[1]
      datas[itemId].push(newdata)
      newdata = null
    } else if(type === 'times') {
      datas[itemId].push(
        this.formatDate(new Date(value[0]), 'yyyy-MM-dd hh:mm:ss') +
        ',' +
        this.formatDate(new Date(value[1]), 'yyyy-MM-dd hh:mm:ss')
      );
    } else if(type === 'time') {
      datas[itemId].push(this.formatDate(value, 'yyyy-MM-dd hh:mm:ss'))
    } else {
      datas[itemId].push(value)
    }
  }
  conditionItems = null
}
