Hi everyone,
I have a problem validating mutiple results using the same input text.
For example,
I use a for loop to display 5 rows of input text
User is require to key in a value in each of the 5 rows
But when i try to validate the 5 rows to check for empty field
The javascript is only able to validate only 1 row of result
Even if it is 10 rows, it only can validate 1 row of result
In other word, the javascript is only able to validate one row of result at any
one time.
How can i validate all the rows using javascript?

Below is the code that i am doing

<form name="main_form" method="post" target="_blank" action="process_coa.asp" onsubmit="javascript:return checkform(this);">
 
 
<% if product = "DBE" then %>
 
<tr>
    <td align=center width=100 class=tableborder>
    <font class="font"><b>MFG<br>LOT#</b></font>
    </td>
 
    <td align=center width=100 class=tableborder style="border-left:0px">
    <font class="font"><b>Loading<br>Date</b></font>
    </td>

Hi,

It is only validating the first row, because all 5 function get the same name:

Code:

function checkform()
{
    ........ check row 1
}

Code:

function checkform()
{
    ........ check row 2
}

When you submit the form, you run function checkform(). Javascript will allways take the top function, so always row 1.

You need to change your javascript to loop through the rows and take it out of your recordset loop, so it doesnt get added 5 times. Simple example:

Code:

function checkform()
{
var error_message;

error_message = "Please complete the following fields\n";

for(var i=1;i ==5;i++)
{
var loaddate = document.main_form.loaddate + i;
 if(loaddate.value == "")
 {
error_message = error_message + "\n - loaddate is missing for record no." + i;
 }
}
if (error_message == "Please complete the following fields\n")
{
return true;
}
else
{
alert (error_message);
return false;
}
}
