[SOLVED] Javascript Help

GreenSmurf · April 15, 2009

Recently a script I have stopped working and I am a little baffled by it. If someone could help point out any errors or potential problems I would appreciate it. There is some PHP involved but the majority of the code is JS.

function MailSelection()
{

  var addresses = "";
  var names = "";
  var business = "";
  var dst_count = 0;
  for (i = 0; i < document.getElementsByName("selected[]").length; i++)

  {
      if( document.getElementsByName("selected[]")[i].checked == true)
      {
         if( document.getElementsByName("selected[]")[i].accept != ""
		&& document.getElementsByName("selected[]")[i].accept != null) {

		addresses = addresses + document.getElementsByName("selected[]")[i].accept + ";";

		if( document.getElementsByName("selected[]")[i].names != ""
			&& document.getElementsByName("selected[]")[i].names != null) {
				names = names + document.getElementsByName("selected[]")[i].names + ";";
				}

		if( document.getElementsByName("selected[]")[i].buss != ""
			&& document.getElementsByName("selected[]")[i].buss != null) {
				business = business + document.getElementsByName("selected[]")[i].buss + ";";
				}
		dst_count++;
         }
      }
  }

   if(dst_count == 0)
       alert("No address selected.");
    else
        location.href = "mail.php?email="+addresses+"&names="+names+"&bus="+business;
}
</script>

Then down my code a bit.

if ($myrow["firstname2"] != "" AND $myrow["email2"] == ""){
             $names=$myrow["firstname"]."-".$myrow["lastname"].";".$myrow["firstname2"]."-".$myrow["lastname2"];
             $emails=$myrow["email"].";".$myrow["email"];
             $biz=$myrow["boss"].";".$myrow["boss"];}
             
        else if ($myrow["firstname2"] != "" AND $myrow["email2"] != ""){
             $names=$myrow["firstname"]."-".$myrow["lastname"].";".$myrow["firstname2"]."-".$myrow["lastname2"];
             $emails=$myrow["email"].";".$myrow["email2"];
             $biz=$myrow["boss"].";".$myrow["boss"];}
             
        else if ($myrow["firstname2"] == "" AND $myrow["email2"] == ""){
             $names=$myrow["firstname"]."-".$myrow["lastname"];
             $emails=$myrow["email"];
             $biz=$myrow["boss"];}
             
        else{
            $names=$myrow["firstname"]."-".$myrow["lastname"].";".$myrow["firstname"]."-".$myrow["lastname"];
            $emails=$myrow["email"].";".$myrow["email2"];
             $biz=$myrow["boss"].";".$myrow["boss"];}

	echo "<TD><input type=checkbox id=".$id." name='selected[]' value='$id' title='Select ($firstname $lastname)' alt='Select ($firstname $lastname)' buss=".$biz." names=".$names." accept=". email_slash($emails)."></td>";

echo "<td><input type=button value=\"Send e-Mail\" onclick=\"MailSelection()\"/></td>";

I would be grateful for any help. Thank you.

Uff that's not the 'sexiest' code I've ever seen, you could seriously shrink down (and improve readability) by using

  var addresses = "";
  var names = "";
  var business = "";
  var dst_count = 0;
  for (var i = 0; i < document.getElementsByName("selected[]").length; i++)
  {
      var cSelected = document.getElementsByName("selected[]")[i];
      if( cSelected.checked )
      {
         if( cSelected.accept != "" && cSelected.accept != null) 
         {         
             addresses += cSelected.accept + ";";
         
             if( cSelected.names != ""&& cSelected.names != null)
               names += cSelected.names + ";";
             if( cSelected.buss != "" && cSelected.buss != null)
               business += cSelected.buss + ";";
             
             dst_count++;
         }
      }
  }

   if(dst_count == 0)
       alert("No address selected.");
    else
        location.href = "mail.php?email="+addresses+"&names="+names+"&bus="+business;
}
</script>

Only possible problem I'm seeing and fixed above is that you didn't use var i = 0; inside the first if statement in the javascript. Thus it will be created as a global variable.. possibly overwriting another variable named i elsewhere in your code.

I tried the new code an it would seem that the button stopped working entirely. When I click it nothing happens the pages just sits there. I am wondering if there is something wrong in/or before the return statement.

I have had more time to get "into" the code and understand the issue. It appears that only the email variables are being passed through the script. What I mean is this:

else
        location.href = "mail.php?email="+addresses+"&names="+names+"&bus="+business;

Comes out as this:

mail.php?email=name@website.com&names=&bus=

The thing of the matter it that there are definite names and business variables that are defined and set in other parts of the code. I just can't find why the names and bus variables won't set or get skipped. It could be getting skipped anywhere in the code too but it has to be after the line of code:

 echo "<TD><input type=checkbox id=".$id." name='selected[]' value='$id' title='Select ($firstname $lastname)' alt='Select ($firstname $lastname)' buss=".$biz." names=".$names." accept=". email_slash($emails)."></td>";

As I have already verified that the variables are set properly after this line of code with some output.

Can you post the HTML for the form? I don't know why you are using getElementsByName() when you can just reference the form directly. :-\

GreenSmurf · May 8, 2009

I can but my code is really sloppy and a bit large, is that ok?

Ken2k7 · May 8, 2009

Just the form itself. I don't need everything.

Here is the <form> code that was requested. Sorry it took so long to reply I have been working on multiple projects. Thanks again.

echo "<TD><input type=checkbox id=".$id." name='selected[]' value='$id' title='Select ($firstname $lastname)' alt='Select ($firstname $lastname)' buss=".$biz." names=".$names." accept=". email_slash($emails)."></td>";

You just gave an INPUT tag attributes that don't exist. ???

This is where I thought the problem was located. What is proper way of resolving this?

GreenSmurf · May 27, 2009

echo "<TD><input type=checkbox id=".$id." name='selected[]' value='$id' title='Select ($firstname $lastname)' alt='Select ($firstname $lastname)'></td>";
	echo "<input type=hidden id=".$id." name='accept' value='accept=". email_slash($emails)."'>";
	echo "<input type=hidden id=".$id." name='names' value='$names'>";
	echo "<input type=hidden id=".$id." name='biz' value='$biz'>";

This is what I tried to fix it with but I am not getting an error that says "No addresses selected." Which means that the code for the JavaScript portion is not seeing that the check boxes are clicked. Most likely due to a misunderstanding of the way the HTML input needs to communicate with the JavaScript.

I found the solution to my problem and made a few adjustments.

The first change in code is:

if( document.getElementsByName("selected[]")[i].accept != ""
		&& document.getElementsByName("selected[]")[i].accept != null) {

		addresses = addresses + document.getElementsByName("selected[]")[i].accept + ";";

		if( document.getElementsByName("names")[i].accept != ""
			&& document.getElementsByName("names")[i].accept != null) {
				names = names + document.getElementsByName("names")[i].accept + ";";
				}

		if( document.getElementsByName("bus")[i].accept != ""
			&& document.getElementsByName("bus")[i].accept != null) {
				business = business + document.getElementsByName("bus")[i].accept + ";";

The second adjustment is:

echo "<TD><input type=checkbox id=".$id." name='selected[]' value='$id' title='Select ($firstname $lastname)' alt='Select ($firstname $lastname)' accept=".email_slash($emails)."></td>";
	echo "<TD><input type=hidden name='names' accept=".$names."></td>";
	echo "<TD><input type=hidden name='bus' accept=".$bus."></td>";

Thanks to all those who helped.
