}

function all_onclick() {
	var flag;
	flag=document.forms("form1").item("all").checked;
	for (i = 1; i < document.forms("form1").length; i++)
	{
		if( document.forms("form1").item(i).name == "ch") 
		{
			document.forms("form1").item(i).checked=flag;
		}
	}
	calc_delid();
}

Code (markup):

Here is some HTML code

	<form id="form1" name="form1">
       <table align="center" bgcolor="#ffffff" border="0" cellpadding="1" cellspacing="1" width="95%">
        <tbody>
          <tr> 
            <td class="header" align="center" height="19" width="6%"><input onclick="all_onclick()" class="checkbox" value="1" name="all" id="all" type="checkbox"> 
              <input id="delid" name="delid" type="hidden"> </td>
            <td class="header" height="19" width="63%">&nbsp; Email Id </td>
            <td class="header" align="center" height="19" width="31%"><div align="center">Status 
              </div></td>
          </tr>
          <tr style="background-color: rgb(244, 244, 244);" onmouseover="this.style.backgroundColor='#FEFAEB';" onmouseout="this.style.backgroundColor='#f4f4f4';" bgcolor="#f4f4f4"> 
            <td align="center"><input id="5" class="checkbox" value="5" name="ch" onclick="ch_onclick(this)" type="checkbox"> 
            </td>
            <td>&nbsp;someone@microsoft.com</td>
            <td class="matter" align="center"><div align="center">Yes </div></td>
          </tr>
          <tr style="background-color: rgb(244, 244, 244);" onmouseover="this.style.backgroundColor='#FEFAEB';" onmouseout="this.style.backgroundColor='#f4f4f4';" bgcolor="#f4f4f4"> 
            <td align="center"><input id="6" class="checkbox" value="6" name="ch" onclick="ch_onclick(this)" type="checkbox"> 
            </td>
            <td>&nbsp;somefrom@yahoo.com</td>
            <td class="matter" align="center"><div align="center">No </div></td>
          </tr>
          <tr> 
            <td colspan="3" align="left"><input name="action" class="buttoncolor" id="action" value="Trash" type="submit"> 
              &nbsp;&nbsp; <input name="action" class="buttoncolor" id="action" value="Active" type="submit"> 
              &nbsp;&nbsp;&nbsp;&nbsp; <input name="action" class="buttoncolor" id="action" value="InActive" type="submit" width="20"> 
              &nbsp;&nbsp; </td>
          </tr>
        </tbody>
      </table>
	  </form>

Code (markup):

 

The reason that works in IE and not Firefox is because you're using JScript syntax, not javascript. Change your syntax to be like

document.forms["form1"].elements[i].name

Code (markup):

 

I suggest always go for standard DOM syntax; and test your Javascript code in Mozilla browsers, I prefere Firefox, because any thing that works in mozilla browser it will work in IE 99% of the time or 100% in my case.

I have never faced any javascript problem, when I followed standard syntax and tested in mozilla browsers.

 

What about some "blink" codes? Is it works?
