[SOLVED] Need Function to Work With Multiple Forms

[limitphp]

Is it possible to change this part in a function used by multiple forms:

function myfunc(num){

  document.frmPlaylist.newName.value;

}

 

into this:

function myfunc(num){

  document.frmPlaylist+num.newName.value;

}

 

in other words, I have a page that may have a bunch of forms on it....

each form would be called frmPlaylist4, frmPlaylist35, frmPlaylist22, etc....

 

I want to send that number to the function and make it part of the form name.  Is that possible?

 

thanks

Use something along the lines of:

function myFunc(num)
{
   document.forms["frmPlaylist" + num].elements["newName"].value = "blah";
}

How would I do that with checkboxes, if I had multiple ones with the same name?

right now i use:

document.frmPlaylist.playlist[a].checked

 

would I convert that into this:

document.forms["frmPlaylist" + num].elements["playlist"][a].checked

?

Why not just pass "this" into the function?

 

 

For example:

 

<form onsubmit="SomeFunction(this);">

 

 

Then the parameter would be the same thing as what you would get with document.formname.

thanks for the tip corbin, I thought about that...but I can't....because I call the function when they click the submit button, not the checkboxes and textbox.....

 

its complicated.....its for an ajax request.....

 

anyway, Nightslyr, it worked!!!!!!

 

my goodness, you are awesome!

What does a submit button do?  It submits a form >.<.

 

 

If you do onsubmit="blah(); return false;"

 

 

The form will not submit.

Actually thats not true....I tried that.

I moved my ajax call to the <form tag instead of the button and when I tried to put the ajax function in front of the return false, it submitted the darn thing.....

 

anyway, I really appreciate you responding corbin.  You're always willing to help m out and I really appreciate that.  Even when Maq and premiso get tired of my butt.

 

ultimately, I like using this:

document.forms["frmPlaylist" + num].elements["newName"].value = "blah";

 

because it gives you even more control....

Example of non-submitting form:

 

<script language="javascript">
function blah(f) {
return false;
}
</script>

<form action="blah.html" method="GET" onsubmit="return blah(this);">
<input type="hidden" name="hidden" value="omg a value!" />
<input type="submit" />
</form>

 

 

But, what ever works ;p.

Oh yeah...I could have just put it all in one function.....

yeah, I guess that would have worked too...
