面对批量更新之字符串的拼接

Posted 2020-07-31 厚积薄发

背景：SSH框架、页面采用dwz框架

需求：实现批量审批的功能

实现方法：带逗号拼接字符串传值

1.html 代码

 1 <table class="table" width="100%" layoutH="112">
 2         <thead>
 3             <tr>
 4                 <th width="40" align="center"><input type="checkbox" id="bll" onclick="toCheckAll(this.value)"/></th>     
 5             </tr>
 6         </thead>
 7         <tbody>
 8             <s:iterator value="" status="" id="uid">
 9                 <tr target="sid" id="${id}" align="center">
10                     <td><input type="checkbox" value="" id="cc" name="ibs"/>
11                 </tr>
12             </s:iterator>
13         </tbody>
14 </table>

 

2.js代码

 1 <script type="text/javascript">
 2 function toCheckAll(val){
 3     var hobbys = document.getElementsByName("ibs");
 4     
 5     var isAll = document.getElementById("bll");
 6     
 7     for(var i=0;i<hobbys.length;i++){
 8         hobbys[i].checked=isAll.checked;
 9 
10     }
11 }
12 
13 function plspShow(){
14     var id =  $(‘input:checkbox:checked‘).attr("value");
15     var arr = $(‘input:checkbox:checked‘);
16     
17     if(arr.length==0){
18         alertMsg.info("请选择一条记录");
19     }else{
20         var hobbys = document.getElementsByName("ibs");
21         var bb="";
22         var temp="";
23         for(var i=0;i<hobbys.length;i++){
24             if(hobbys[i].checked){
25                 temp=hobbys[i].value;
26                 bb=bb+temp+",";
27             }
28         }
29         console.log(bb+"=="+bb.substring(0, bb.length-1));
30         $.pdialog.open("bk_plbksh.action?id="+bb.substring(0, bb.length-1),"id","批量审批",{width:550,height:450,mask:true,maxable:false});
31     }
32 }
33 </script>

3.Action 代码

 1 public String plbksh() throws Exception{
 2     String[] fg = id.split(",");
 3     for (int i = 0; i < fg.length; i++) {
 4        bkobj = this.bkService.loadBkById(Long.valueOf(fg[i])); 5     }
 6    return SUCCESS;
 7 }
