蓝凌表单的表体调用Javascript

--计算时间段函数：calTime()
--代码如下：
var B=0;
var E=0;
var RowNum=document.all.edittable_OverTimeApplyDetail_tData.rows.length;
for(var i=0;i<RowNum;i++)
{
 if(document.all.edittable_OverTimeApplyDetail_tData.rows(i).display==‘none‘)
 {continue;}
var j1="BeginTime_"+(i+1);
var obj1=document.getElementById(j1);
var j2="EndTime_"+(i+1);
var obj2=document.getElementById(j2);
var j3="Amount_"+(i+1);
var obj3=document.getElementById(j3);


if(obj1.value==null || obj1.value==‘‘ || obj2.value==null || obj2.value==‘‘){break;}
else
{
//取开始时间
if(((obj1.value).substring(3,5))==‘30‘)
{if(parseInt((obj1.value).substring(0,1))==0){B=parseInt((obj1.value).substring(1,2))+0.5;}
 else{B=parseInt((obj1.value).substring(0,2))+0.5;}
}
else
{if(parseInt((obj1.value).substring(0,1))==0){B=parseInt((obj1.value).substring(1,2));}
 else{B=parseInt((obj1.value).substring(0,2));}
}
//取结束时间
if(((obj2.value).substring(3,5))==‘30‘)
{if(parseInt((obj2.value).substring(0,1))==0){E=parseInt((obj2.value).substring(1,2))+0.5;}
 else{E=parseInt((obj2.value).substring(0,2))+0.5;}
}
else
{if(parseInt((obj2.value).substring(0,1))==0){E=parseInt((obj2.value).substring(1,2));}
 else{E=parseInt((obj2.value).substring(0,2));}
}


if((E-B)>0){document.getElementById(j3).value=E-B;}
else {alert(‘结束时间不能小于开始时间！‘);}

}

}

var divObj=document.getElementById(‘divMainForm‘);
if(divObj)
 {var tr=divObj.getElementsByTagName(‘tr‘);
  if(tr)
   {
    tr[2].style.display=‘none‘;
   }
 }

----检查从表中输入的时间（取数据字典）值是合法格式

var RowNum=document.all.edittable_请假明细_tData.rows.length;
for(var i=0;i<RowNum;i++)
{
 if(document.all.edittable_请假明细_tData.rows(i).display==‘none‘)
 {continue;}
var j1="开始时间_"+(i+1);
var obj1=document.getElementById(j1);
var j2="截止时间_"+(i+1);
var obj2=document.getElementById(j2);

if(obj1.value==null || obj1.value==‘‘ || obj2.value==null || obj2.value==‘‘){break;}
else
{
 //取开始时间
 if(obj1.value.substring(2,3)!=":"|| obj1.value.length!=5 )
 {alert("您输入的时间格式不符，请重新输入!");
 obj1.value="";
 }
 //取结束时间
 if(obj2.value.substring(2,3)!=":"|| obj2.value.length!=5 )
 {alert("您输入的时间格式不符，请重新输入!");
 obj2.value="";
 }

}

}
