为什么我不从这些接收文本框中

的我的岗位值，使用JavaScript来计算总MARK1，MARK2，MARK3总的平均环IAM ...为什么我不从这些接收文本框中

<input type="text" name="tblRowCount" id="tblRowCount" /> 
    <table align="center" width="100%" border="0" class="table_Style_Border" id="table"> 
     <input type="text" name="txtrowcount" id="txtrowcount" /> 
my for loop is this 
    $a = 1; 
      for($i=0;$i<sizeof($StudName);$i++) { ?> 
     <tr align="left"> 
     <td class="table_label"><? echo $code[$i].' - '.$StudName[$i]; ?></td> 

     <td><input type = "text" name="mark1<?= $a ?>" id="mark1<?= $a ?>" ></td> 
     <td><input type = "text" name="mark2<?= $a ?>" id="mark2<?= $a ?>" ></td> 
     <td><input type = "text" name="mark3<?= $a ?>" id="mark3<?= $a ?>" 
     onkeyup="return percent('mark1<?= $a ?>','mark2<?= $a ?>','mark3<?= $a ?>','total<?= $a ?>','Average<?= $a ?>')" ></td> 
     <td><input type = "text" name="total<?= $a ?>" id="total<?= $a ?>" 
     onkeyup="return percent('mark1<?= $a ?>','mark2<?= $a ?>','mark3<?= $a ?>','total<?= $a ?>','Average<?= $a ?>')"></td> 
     <td><input type = "text" name="Average<?= $a ?>" id="Average<?= $a ?>" ></td> 
    </tr> 
    <? $a++; } ?>

这是我的javascript

function percent(mark1,mark2,mark3,total,Average) 
{ 
    var tbl = document.getElementById('table'); 
    var mark1value=document.getElementById(mark1).value; 
    var mark2value=document.getElementById(mark2).value; 
    var mark3value=document.getElementById(mark3).value; 
    var totalvalue=document.getElementById(total).value; 
    var averagevalue=document.getElementById(Average).value; 
    total_1 = parseInt(mark1value)+parseInt(mark2value)+parseInt(mark3value); 
    average_1 = total_1/3; 
    document.getElementById(total).value = total_1.toFixed(2); 
    document.getElementById(Average).value = average_1.toFixed(2); 

} 
function tblrowcount() 
    { 
     var tblid = document.getElementById('table'); 
     //alert(tblid); 

     //alert(tblRowcount); 
     document.getElementById('txtrowcount').value = tblid.rows.length-1; 
     return true; 
    } 
function removeRowFromTable() 
    { 
     var tbl = document.getElementById('table'); 
     var lastRow = tbl.rows.length; 
     if (lastRow > 2) 
     { 
     tbl.deleteRow(lastRow - 1); 
     document.getElementById('tblRowCount').value=tbl.rows.length-1; 
     } 
    }

我怎样才能收到后值我想是这样，但对我来说

function Addmark() 
    { 

    for($a=1;$a<=$rowcount;$a++) 
    { 

     $markI='mark1'.$a; 
     $markII='mark2'.$a; 
     $markIII='mark3'.$a; 
     $total='total'.$a; 
     $avg='Average'.$a; 

     $mI[] = $this->input->post($mark1); 
     $mII[] = $this->input->post($mark2); 
     $mIII[] = $this->input->post($mark3); 
     $Total[] = $this->input->post($total); 
     $Avrg[] = $this->input->post($Average); 

    } 

     $res = $this->staffModel->Addmark($mI,$mII,$mIII,$Total,$Avrg); 


       if($res==true) 

         { 
          $this->session->set_flashdata('response', 'data added successfully !'); 
         } 
        else 
         { 
          $this->session->set_flashdata('response', 'data already exist !'); 
         } 

       $this->load->view('Sstudentlist',$data); 
}

我怎样才能得到的值

首先用后面添加自己的名字创建的输入作为数组[]如：

<input type = "text" name="mark[]" id="mark1<?= $a ?>" > 
<input type = "text" name="mark[]" id="mark2<?= $a ?>" > 
<input type = "text" name="mark[]" id="mark3<?= $a ?>" > 
...and so on

现在你可以像这样从POST访问var这样的：

$_POST['mark']

现在在你的函数，而不是写：

function Addmark() 
{ 

    for($a=1;$a<=$rowcount;$a++) 
    { 

    $markI='mark1'.$a; 
    $markII='mark2'.$a; 
    $markIII='mark3'.$a; 
    $total='total'.$a; 
    $avg='Average'.$a;

写这个：

function Addmark() 
{ 
    global $_POST; // i assume that your post gets through on this page 

    for($a=1;$a<=$rowcount;$a++) 
    { 

    $markI=$_POST['mark'][0]; // since arrays start at 0 
    $markII=$_POST['mark'][1]; 
    $markIII=$_POST['mark'][2]; 
    $total=$_POST['mark'][3]; 
    $avg='Average'.$a; 

    // and then same rest of the code....
