Subject: [PATCH] update ruoyi-ui/src/views/system/user/index.vue. handleUpdate(row)方法中：this.form = response.data;语句 会导致【this.form.postIds = response.postIds;】和【this.form.roleIds = response.roleIds;】失效。 导致用户编辑对话框中，角色和部门多选框无法正常修改。 建议使用以下语句修改： this.$set(this.form, "postIds", response.postIds); this.$set(this.form, "roleIds", response.roleIds);
