Vue单行与批量删除
~Phoenix 人气:0单行删除与批量删除
一、单行删除
<el-table-column align="center" fixed="right" label="操作" width="100"> <template slot-scope="scope"> <el-button type="text" size="small" icon="el-icon-edit"></el-button> <el-button @click="handleClick(scope.row)" type="text" size="small" icon="el-icon-delete" ></el-button> </template> </el-table-column>
在对应的删除按钮添加事件scope.row保证选中当前行
export default { data() { const data = []; return { //删除记录的code deleteCode: [] }; },
methods: { //Table里的点击删除图标\ async handleClick(row) { const confirmResult = await this.$confirm( "此操作将永久删除该文件, 是否继续?", "提示", { confirmButtonText: "确定", cancelButtonText: "取消", type: "warning" } ).catch(err => err); if (confirmResult !== "confirm") { return this.$message.info("已取消!"); } this.deleteCode.push(row.id); //调用的删除接口 const { data: res } = await this.$axios.delete( "/questionCheck/updateIsDelete/" + this.deleteCode, { data: this.deleteCode } ); if (res.code != "SUCCESS") { return this.$message.error("删除信息失败!"); } this.deleteCode = []; }, }
二、批量删除
<el-button @click="batchDeleteBuild(multipleSection)" plain>批量删除</el-button>
export default { data() { return { //被选中的列表记录 multipleSection: [], }; },
methods: { //批量删除选中数据方法 async batchDeleteBuild() { //判断是否选择了数据 if (this.multipleSection.length == 0) { alert("请选择要删除的数据"); return; } //如果有选中的数据,那么弹出消息框 const confirmDelete = await this.$confirm( "此操作会永久删除建筑信息,是否删除?", "提示", { confimrButtonText: "确定", cancelButtonText: "取消", type: "warning" } ).catch(err => err); //如果用户确认删除,则返回字符串confirm //如果用户取消删除,则返回字符串cancel if (confirmDelete !== "confirm") { return this.$message.info("已取消"); } //将选中的数据推到deleteCode数组中 for (var i = 0; i < this.multipleSection.length; i++) { var j = i; var id = this.multipleSection[j].id; this.deleteCode.push(id); } //删除deleteCode中的数据 const { data: res } = await this.$axios.delete( "/question/DeleteQuestionBatch", { data: this.deleteCode } ); if (res.code != "SUCCESS") { return this.$message.error("删除课程信息失败!"); } this.deleteCode = []; }, }
简单的批量删除,全选删除
