迭代GridView使用Javascript或jQuery查找最大值

我有一個gridview和場景是：一旦有人刪除一行，它會檢查NOTIF_RECIP_SEQ_NBR是否最大。如果是，那麼它刪除那一行，否則給一個彈出。迭代GridView使用Javascript或jQuery查找最大值

所以基本上一旦有人點擊刪除，它會得到該行的NOtif_recip_Id並遍歷Gridview，查看與該NOTIF_RECIP_ID對應的任何行的NOTIF_RECIP_SEQ_NBR是否更大。

問題是否可以在客戶端？我在服務器端做過，但當我擁有客戶端的所有數據時，我認爲這不是一個好方法。

請幫忙。我用Javascript嘗試了多種方式，但沒有用。

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head id="Head1" runat="server"> 
<script type="text/javascript"> 

    function check(var a ,var b) 
    { 

     var grid = document.getElementById("GridView1"); 
     var cellPivot; 
     debugger; 
     if (grid.rows.length > 0) { 
      for (i = 1; i < grid.rows.length-1; i++) 
      { 

//here I want code to iterate and compare value.Is it possible? 
      alert("You must select an answer for all columns if Pivot is yes") 
      } 

    } 

</script> 
</head>

我發現解決方案如此粘貼任何需要的人。

<script type = "text/javascript"> 
     function GetSelectedRow(lnk) { 
     debugger; 
      var table, tbody, i, rowLen, row, j, colLen, cell; 

      var result = confirm('Do you want to delete this value ?'); 
      if (result) { 

       var x = document.getElementById('Label100'); 


       table = document.getElementById("GridView1"); 
       tbody = table.tBodies[0]; 

       var bool = true; 
       var row = lnk.parentNode.parentNode; 
       var rowIndex = row.rowIndex - 1; 

       var RecipID = row.cells[0].innerText; 
       var Sqqno = parseInt(row.cells[1].innerText); 

       for (i = 1, rowLen = tbody.rows.length; i < rowLen; i++) { 
        row = tbody.rows[i]; 

        var newrecipId = row.cells[0].innerText; 
        if (newrecipId == RecipID) { 
         cell = row.cells[1]; 

         var newseq = parseInt(row.cells[1].innerText); 
         if (Sqqno < newseq) { 
          // debugger; 
          bool = false; 
          x = document.getElementById('Label100'); 
          x.innerHTML = "ERROR-Delete RecipId with max Seqnumber"; 
          x.style.display = "block"; 

          return bool; 
          break; 
         } 

        } 
        else { 
         bool = true; 
        } 

       } 

       return bool; 
      } 
      else { 
       return false; 
      } 

     } 
    </script>
