本文實(shí)例為大家分享了Java實(shí)現(xiàn)多選批量刪除功能的具體代碼，供大家參考，具體內(nèi)容如下
選擇前效果圖
選中效果圖
前端vue代碼
1、頁面顯示template
使用方法 @selection-change=“changeFun” 獲取表中選中的行所有顯示的數(shù)據(jù)
<template>
<div class="dept tab-container">
<div class="dept-table">
<div id="query" class="newTable">
<!-- 列表數(shù)據(jù)展示-->
<el-table
:data="list"
border
fit
style="width: 100%;"
v-loading="loading"
element-loading-text="請給我點(diǎn)時(shí)間！"
@selection-change="changeFun"
>
<el-table-column type="selection" width="55" v-model="checkBoxData"></el-table-column>
<el-table-column align="center" label="姓名" min-width="60px">
<template slot-scope="scope">
<span>{{scope.row.name }}</span>
</template>
</el-table-column>
<el-table-column align="center" label="記錄類型" min-width="80px">
<template slot-scope="scope">
<span>{{getTypeName(scope.row.type)}}</span>
</template>
</el-table-column>
<el-table-column align="center" label="返回信息" min-width="180px">
<template slot-scope="scope">
<span>{{scope.row.message }}</span>
</template>
</el-table-column>
<el-table-column align="center" label="創(chuàng)建人">
<template slot-scope="scope">
<span>{{scope.row.createUserId}}</span>
</template>
</el-table-column>
<el-table-column align="center" label="創(chuàng)建時(shí)間" min-width="55px">
<template slot-scope="scope">
<span>{{parseTime(scope.row.createDateTime)}}</span>
</template>
</el-table-column>
<el-table-column align="center" label="最后修改人">
<template slot-scope="scope">
<span>{{scope.row.modifyUserId}}</span>
</template>
</el-table-column>
<el-table-column align="center" label="最后修改時(shí)間" min-width="55px">
<template slot-scope="scope">
<span>{{parseTime(scope.row.modifyDateTime)}}</span>
</template>
</el-table-column>
<el-table-column class-name="status-col" min-width="100px" label="操作">
<template slot-scope="scope">
<el-button class="btn" size="mini" type="danger" @click="delHandle(scope.row.id)" v-if="isButtonShow("userDel")">刪除</el-button>
</template>
</el-table-column>
</el-table>
<!-- 批量刪除-->
<br />
<div style="float: left;">
<el-button class="btn" size="mini" :disabled="btnChangeEnable" @click="delBatchHandle" type="danger">批量刪除</el-button>
</div>
<br />
<!--分頁 begin-->
<div class="pagination-container">
<el-row>
<el-col :span="19">
<el-pagination
background
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="listQuery.current"
:page-sizes="[10,20,30, 50]"
:page-size="listQuery.size"
layout="total, sizes, prev, pager, next, jumper"
:total="total"
></el-pagination>
</el-col>
</el-row>
</div>
<!--分頁 end-->
</div>
</div>
</div>
</template>
2、定義顯示值
data(){
return{
btnChangeEnable: true, // 批量刪除禁用
checkBoxData: [], //多選框選擇的值
}
}
3、選中時(shí)觸發(fā)方法
@selection-change=“changeFun”
// 獲取多選框選中的值
changeFun(val) {
console.log(val)
this.checkBoxData = val;
if(val == ""){
this.btnChangeEnable = true;
} else {
this.btnChangeEnable = false;
}
},
4、批量刪除按鈕綁定事件
<el-button class="btn" size="mini" :disabled="btnChangeEnable" @click="delBatchHandle" type="danger">批量刪除</el-button>
5、觸發(fā)事件
導(dǎo)入 axios
import axios from "axios";
// 批量刪除
delBatchHandle() {
this.$confirm("確定要?jiǎng)h除嗎?", "提示", {
confirmButtonText: "確定",
cancelButtonText: "取消",
type: "warning"
}).then(() => {
// 解析checkBoxData中的id值，也可以解析其他包含的數(shù)據(jù)
var ids = this.checkBoxData.map(item => item.id).join()//獲取所有選中行的id組成的字符串，以逗號分隔
console.log(ids)
axios.post("/verityRecord/deleteBatch", { vrDatas: ids }).then((result) => {
if (result.code == "0000") {
this.$message({
type: "success",
message: "操作成功!"
})
this.getList()
} else {
this.$message({
type: "error",
message: "操作失敗!"
})
}
})
}).catch(() => {
this.$message({
type: "info",
message: "已取消操作"
})
})
}
后臺接收并解析
/**
* 批量刪除信息
* <p>
* author:
* @param paramsMap
* @return
*/
@RequestMapping(value = "/deleteBatch", method = RequestMethod.POST)
public void deleteBatch(@RequestBody Map<String, Object> paramsMap) {
if (paramsMap != null && paramsMap.size() > 0) {
String vrDatas = paramsMap.get("vrDatas").toString();
String[] ids = vrDatas.split(",");
for (String id : ids) {
// 根據(jù)自己的service方法邏輯處理
}
}
}
以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
