### 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。

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。**

                        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']"

                            </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。
