Get values of text boxes in function

[sasimca007]

Hello friends,
I have one critical doubt on textboxes. That is, I am using modperl and in that within one loop i am giving nof.of text boxes with different names like below:

foreach $W($week1,$week2,$week3,$week4,$week5,$week6,$week7)
{
    print "<td align=center><input type='text'  name='$code-$testdate'  id='reg_box_parent' value='$shcode' size=3  onkeyup='func(this.form,this.name)'  maxlength=8>";
}
 

The javascript function func code is

function func(frm,nam)
{
    alert(nam);
    var txt = document.frm.nam.value;
    alert(txt);
}
 

So here, i am getting nam alert but that value i am not getting.
For example, in the loop i am displaying 7 textboxes at a time and those having 7 different names like 3147217-2008-03-16,3147217-2008-03-17,3147217-2008-03-18,
3147217-2008-03-19,3147217-2008-03-20,3147217-2008-03-21,
3147217-2008-03-22
But how to get the values of those textboxes in the function.

As a full member now, you should know that we expect your code to be posted in [code] tags (See How to Ask a Question).

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use the tags in future.

Also remember to provide a meaningful title for any threads started (see the FAQ entry Use a Good Thread Title).

Since you're already passing the actual form object, use it. Also use the form elements array to refer to the textbox using the nam string:

function func(frm,nam)
{
    //alert(nam);
    var txt = frm.elements[nam].value;
    alert(txt);
}

Better still, just pass the actual textbox object instead of the name:

print "<td align=center><input type='text'  name='$code-$testdate'  id='reg_box_parent' value='$shcode' size=3  onkeyup='func(this)'  maxlength=8>";

function func(obj)
{
    var txt = obj.value;
    alert(txt);
}
