如何使用el-table+el-tree+el-select动态选择对应值

作者:紫米粥

小编在做需求时,遇到了在el-table表格中加入多条数据,并且每条数据要通过el-select来选取相应的值,做到动态选择,下面这篇文章主要给大家介绍了关于如何使用el-table+el-tree+el-select动态选择对应值的相关资料,需要的朋友可以参考下

使用el-table+el-select+el-tree来实现element中el-table表格动态选择对应值

背景描述:

项目组的老大让我们完成一个选择一个下拉框中的值,然后再动态选择该下拉框中树形结构的数值,说起来有点绕,给大家截个图,大家就一目了然了。

其实这个功能的实现主要借助与el-table、el-tree、el-select这三个组件就可以实现。

我碰到的问题:

(1)el-tree数据不显示。

(2)el-tree显示数据后无法绑定某一行。

(3)el-tree不能及时同步显示数据。

但是一开始做的时候一头雾水,因为我是做后端的,其实对前端的知识真的了解的不多,所以,在苦心钻研了一天终于参考了一篇大神的博客,成功解决的这个问题。

在这里附上原文地址:https://www.jb51.net/article/272778.htm

解决问题:

根据大神的文章,我对其中的方法进行了主要的修改,然后按照大神的逻辑,重新修改了页面,发现就成功了,在这里具体什么原因其实我也不知道,但是在这里附上源码,方便大家进行参考。

其实核心主要是三大方面:

(1)第一步,选中下拉框,获取树形数据。

<el-form>
                <el-form-item label="用户地址" prop="aloWhTo">
                    <el-select v-model="form.aloWhTo" @change="testConsistent" placeholder="" readonly filterable style="width:95%" >
                        <el-option v-for="item in WarehouseOptions" :key="item.whId" :label="item.whName" :value="item.whId">
                        </el-option>
                    </el-select>
                </el-form-item>
            </el-form>

补充:大家在前端指导如何把数据转成树形结构吗?

其实很简单:只需要借助于handleTree()方法即可,但是在合理提前是你查询的数据是包含这种父子关系的字段的,比如我这里的wliFd这个字段就很关键。

listWarehouseLocationInfo(this.queryParamsByLocation).then(response => {
      this.WarehouseLocationInfoList = this.handleTree(response.data, 'wliId', 'wliFId')
      console.log("我是最终要返回的数据")
      console.log(this.WarehouseLocationInfoList)
      })

(2)通过@change="testConsistent"获取树形结构数据treeList,在这里我主要是模拟的树形数据。

                                "backup3": null
                            },
                            "wliFId": 0,

                    ];
                console.log(this.form.aloWhTo)
                if(this.form.aloWhTo === 2){
                    this.treeList = data;
                }else {
                    this.treeList = null;
                }
            },

(3)修改el-table中的el-table-column,并将el-select、el-tree进行数据绑定,这里具体的参数大家可以参照我推荐的大神的博客,在这里我就不一一介绍了。

 <el-table-column label="地址" prop="address">
                    <template slot-scope="scope">
                    <el-select
                            :ref="'address' + scope.$index"
                            v-model="userlist[scope.$index]['address']"
                            placeholder="请选择地址类别"
                            clearable
                    >
                        <el-option :value="userlist[scope.$index]['address']" style="height: auto">
                            <el-tree
                                    :ref="'addressTree' + scope.$index"
                                    :data="treeList"
                                    node-key="wliId"
                                    :props="defaultPropsList"
                                    @node-click="getTypeList(scope.$index)"
                            >
                                <span slot-scope="{ node }">{{ node.label }}</span>
                            </el-tree>
                        </el-option>

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

(4)编写getTypeList(scope.$index),这个方法才是核心,大家按照这个逻辑改一下ref的名字还有数据表的名字即可使用,方便快捷,并且能够实现相应的功能。

 getTypeList(index) {
                // .getCurrentKey()获取到当前要选择节点的key值
                // 使用此方法必须设置 node-key 属性,若没有节点被选中则返回 null
                const nodeId = this.$refs['addressTree' + index].getCurrentKey()
                // .getNode(nodeId) 根据 data 或者 key 拿到 Tree 组件中的 node
                const node = this.$refs['addressTree' + index].getNode(nodeId)
                // 根据index给当前元素的categoryName参数赋值
                this.$set(this.userlist[index], 'address', node.label)
                //this.$set(this.userlist[index], 'categoryNo', node.data.docTypeNo)
                // 此时页面上已经可以动态选择
                // 这一步是通过判断当前元素的v-model是否有值来控制el-option是否隐藏
                if (this.userlist[index].address) {
                    // .blur()用来隐藏当前展开的下拉选择框
                    this.$refs['address' + index].blur()
                }
            },

至此到这里就全部结束了。
