解决方法

增加change事件方法，处理选中的value值

1.单选

<el-cascaderv-model="tags2":options="newOptionObj.zhuanjiaList":show-all-levels="false":props="{ value: 'userId', label: 'nickName' }"clearable@change="tags2Handle(tags2)"
></el-cascader>//方法
tags2Handle(val) {this.tags2 = val[val.length - 1];
},

2.多选

<el-cascaderv-model="tags1":options="newOptionObj.zhuanjiaList":show-all-levels="false":props="{value: 'userId',label: 'nickName',multiple: true,}"clearable@change="tags1Handle(tags1)"
></el-cascader>//方法：
tags1Handle(val) {let tags1Arr = [];//取出多选的数组中每项的最后一项的值val.forEach((item) => {tags1Arr.push(item[item.length - 1]);});this.expertIds = tags1Arr.join(",");//将数组转为以‘,’分割的字符串
},
