         这是前几天的东西了,现在整理出来:

(1)工作笔记中前面提到了动态的添加javascript的东西,现在要循环把动态添加的东西取出来,这是方法:

 

< script language = " javascript " >
     
     var total  =   0 ;
             //  添加文件地址方法
            function addvindicatorupdate(value1,value2,value3) ... {
               
                //alert(total);            
                var index = t1.rows.length;
                //alert(index);
                var oRow1=t1.insertRow(index);        
                
                var aRows=t1.rows;
                var aCells1=oRow1.cells;
                
                var oCell1_1=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_1.setAttribute("align","center");
                var oCell1_2=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_2.setAttribute("align","center");
                var oCell1_3=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_3.setAttribute("align","center");
                
                var address = "address" + total;
                var userId = "userId" + total;
                var vindicator = "vindicator"+total;
                var  userName ="userName"+total;
                total += 1;
                //alert(total)
                oCell1_1.innerHTML='';
                oCell1_2.innerHTML='文件地点:';
                oCell1_3.innerHTML='<input type="text" size="30" id="' + address + '" name="address" maxlenth="300" value="' + value1 + '" class="ddinput">'
                                 + '<input type="hidden" id="' + userId + '" name="vuserId" value="' + value2 + '">'+'&nbsp;'+'保管人:'
                                 +'<input type="text" name="vindicator" id="'+vindicator+'" size="10" value="' + value3 + '">'
                                 + '<input type="button" name="button1" value=" 选择 " size="20" class="input" onclick="return showModalDpReturn('<%=request.getContextPath()%>/infpm/userMiddle.jsp?check=one','600','600',' + vindicator + ',' + userId + ')"/>';
                                
                     
            }  
            
             //  添加文件地址方法
            function addvindicator() ... {
                //alert(total);            
                var index = t1.rows.length;
                //alert(index);
                var oRow1=t1.insertRow(index);        
                
                var aRows=t1.rows;
                var aCells1=oRow1.cells;
                
                var oCell1_1=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_1.setAttribute("align","center");
                var oCell1_2=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_2.setAttribute("align","center");
                var oCell1_3=aRows(oRow1.rowIndex).insertCell(aCells1.length);
                //oCell1_3.setAttribute("align","center");
                
                var address = "address" + total;
                var userId = "userId" + total;
                var vindicator = "vindicator"+total;
                var  userName ="userName"+total;
                total += 1;
                //alert(total)
                oCell1_1.innerHTML='';
                oCell1_2.innerHTML='文件地点:';
                oCell1_3.innerHTML='<input type="text" size="30" id="' + address + '" name="address" maxlenth="300" class="ddinput">'
                                
                                 + '<input type="hidden" id="' + userId + '" name="vuserId">'+'&nbsp;'+'保管人:'
                                 +'<input type="text" name="vindicator" id="'+vindicator+'" size="10">'
                                 + '<input type="button" name="button1" value=" 选择 " size="20" class="input" onclick="return showModalDpReturn('<%=request.getContextPath()%>/infpm/userMiddle.jsp?check=one','600','600',' + vindicator + ',' + userId + ')"/>';
                                
                     
            }  
     
     
      // 删除收件人
     function deletevindicator() ... {
           var index = t1.rows.length;
           if(index>1)...{            
     t1.deleteRow(index-1);
    //t1.deleteRow(index-2);
    //t1.deleteRow(index-3);
     total = total - 1;
    }
    //alert(total);
            }
</ script >

<%
       String value1 = "" ;
       String value2 = "" ;
       String value3 = "" ;
   if (listaddress  !=   null )
   ... {
     for(int i=0;i<listaddress.size();i++)
     ...{
         TfileAddress tfileAddress=(TfileAddress)listaddress.get(i);
         value2 = tfileAddress.getTsysUserInf().getUserId().toString();
         value1 = tfileAddress.getAddress();
         value3 = tfileAddress.getTsysUserInf().getUserName().toString();
           
%>
    <script>
          addvindicatorupdate('<%=value1%>','<%=value2%>','<%=value3%>');
    </script>        
<%     
    } 
  } else ... {
       value1="";
       value2="";
       value3="";
%>
    <script>
          addvindicatorupdate('<%=value1%>','<%=value2%>','<%=value3%>');
    </script>    
<%
   }
%>

 

value1 ,value2 ,value3,是添加的时候添加的数据,现在是修改页面,能保证修改.忘了把html页面部分补上了,下面是代码:

 

< table  width ="100%"  border ="0"  cellspacing ="0"  cellpadding ="0" >
               < tr >
                 < td  height ="25"  bgcolor ="#f7f7f7" >
                 < table  id ="t1"  width ="100%"  height ="25"  border ="0"  cellpadding ="0"  cellspacing ="0"  class ="font_14" >
                     < tr >
                       < td  width ="30" > &nbsp; </ td >
                       < td  width ="130" > 文件地点： </ td >
                       < td > <!--  <input type="text" name="address" style="width:40% "/>
                       保管人:<input type="text" name="vindicator" id="vindicator" size="10"/>&nbsp;&nbsp;
                       <input type="hidden" name="vuserId" id="vuserId"/>
                       <input type="button" name="button" value=" 选择 " onclick="return showModalDpReturn('<%=request.getContextPath()%>/infpm/userMiddle.jsp?check=one','600','600',vindicator,vuserId);" class="input"/> -->
                        < input  type ="button"  name ="buttonadd"  value ="增加物理分发"  class ="input"  onclick ="addvindicator()"   />
                        <!--  <input type="button" name="buttondel" value="删除物理分发" class="input" onclick="deletevindicator()" /> -->
                       </ td >
                     </ tr >
                 </ table ></ td >
               </ tr >
               < tr >
                 < td  height ="1"  bgcolor ="#b5b5b5" ></ td >
               </ tr >
             </ table >

得了,顺便把判断循环动态添加的代码里面的判断不能为空的也加上吧,其实我根据需求做的是没有删除功能的,即使页面里动态的表格列出来不填也没关系,action里做了判断的,但是怕需求再次变化,只好加了删除的功能:

if (total  >=   0 ) ... {
            document.getElementById("total").value = total;
       
            var addresses = document.getElementsByName("address");
                
            for(var i=0; i<addresses.length; i++)
            ...{    
                         
                     var name = "address" + i;
                     var addresslist = document.getElementsByName(name);
                    
                     for(var k=0; k<addresslist.length; k++)
                      ...{
                        
                           if(addresslist[k].value=="")
                            ...{
                            
                             alert("文件地址不能为空!");
                                 return false;
                            }
                        
                       }     
             }
            for(var i=0; i<addresses.length; i++)
            ...{
                 var name = "vindicator" + i;
                var vindicatorlist = document.getElementsByName(name);
                 for(var j=0; j<vindicatorlist.length;j++)
                 ...{
                      if(vindicatorlist[j].value=="")
                      ...{
                            alert("保管人不能为空!");
                  return false;
                     }
                 } 
                 
            }
         }

恩,基本上全了,呵呵,睡觉喽!以后忘不了喽,记忆力又好使喽!
