javascript input field not working..?

[remshad]

hey friend i am trying to use automatic html input creation using java script for my new project ....


my problem is the field "type propositon 1:is it answer? ignore this one:" not come into input variable such as $_POST['prop1']


i used

pint_r($_POST) 

and the result was

Array ( [radio1] => on [cid] => 65 [desc] => dfdfdfdfd [submit] => Submit )

why my javascript created input field come into role?


my php html code is

<table>
  <form  action="new.php" method="post">
   
   
 <tr><td>
 question type:<br />
True or False:<input type="radio" name="radio1">
Objective:<input type="radio" name="radio2">
Other:<input type="radio" name="radio3" >
</td></tr>
<textarea name="desc" rows="6" cols="35" ></textarea> <br />
<a href="javascript:add()" ><b>add proposition</b></a> 
<div id="cat"></div>
<div id="num" style="display:none;"></div>
<br> </table> 

and the java script is ...

  <script language="javascript" type="text/javascript">
   
    function add()
    {   
        k=document.getElementById("num").innerHTML
        k=parseInt(k);
         if(!k)
        {document.getElementById("num").innerHTML=1;
        k=1;} 
        else{
           document.getElementById("num").innerHTML=k+1;
           k++;
        }  
         document.getElementById("cat").innerHTML+="<tr><td>type propositon "+(k)+":<input type=\"text\" name=\"prop"+k+"\"><td>is it answer? </td> <td> <input type=\"checkbox\" name=\"ans"+k+"\"></td><td><td>     ignore this one:</td><input type=\"checkbox\" name=\"ign"+k+"\"></td></td></tr><br>"            
       
    }


</script>

You can not nest a table's row inside a div element. It is HTML illegal.

You should use TBODY elements instead of DIVs if you want to add new rows into a TABLE. And you should use DOM methods (createElement(), createTextNode(), appendChild()...) not innerHTML. innerHTML is not a standard DOM method and, in case of IE, it works as a read-only method in case of tables and their elements (tr, td...)

DOM example:

i am not lazy ... but new in the field of DOM element ...

http://www.w3schools.com/jsref/met_table_insertrow.asp used InnerHTML ?

I would rather use document.createElement(). Need an example?
