Hi Guys,

    I have a parent and child window. From the child window trying to add a item to the SELECT OPTION placed in the parent window, its giving the err "The Server threw an exception". Any idea would be appreciated.

here is the code,

window.opener.ReEntry.skills.options[ window.opener.ReEntry.skills.length + 1 ]=new Option(data.value);

window.opener.ReEntry.skills - parent widow's select option.
data.value - text input value in the child window

Best Regards,
Siva

Hello Siva,

this is a standard problem that you try to fetch memory in a popup window for object referenced in parent window.
The new Option() reserves memory for the options.

Second problem is that your form is child of document, not of window.

Better is to do it like this:

  popform = document.forms[0];
  opt = window.opener.document.ReEntry.skills.options;
  newOpt = opt.length;
  opt[newOpt].text =  popforn.data.value;
  opt[newOpt].value =  popforn.data.value;


Good luck,
NetGroove

I ran into this problem a while back where I tried to manipulate a select list on a parent window via a function on the child. It worked fine on NS but threw this error with IE. The way that I got around it is as follows:

1) Move the function from the child window to the parent window
2) Change the way that you call the function to something like this:

window.opener.yourFunction(strParameter);

What will happen now is the that the select list will be manipulated by a function on the same page, and all will work well.

So, on the parent window, create a function called addItem()

function addItem(strValue,strText){
   var objSel = document.forms['ReEntry'].elements['.skills'];
   objSel[objSel.length].value =  strValue;
   objSel[objSel.length].text =  strText;
}


and then you can call it from you child like this:

window.opener.addItem('Excel','Microsoft Excel');

Sorry, my version contained several typos.

Here a tested version:

<html>
<head>
<script>
function addOpt(){
 popform = document.forms[0];
 opt = window.opener.document.ReEntry.skills.options;
 newOpt = opt.length;
 opt.length = newOpt+1;
 opt[newOpt].text = popform.data.value;
 opt[newOpt].value = popform.data.value;
}
</script>
</head>
<body>
<form>
<input type=text name="data">
<input type=button value=Add onClick="addOpt()">
</form>
</body>
</html>


And the parent form is something like this:
<html>
<body>
<form name=ReEntry>
<select name=skills>
<option>One
</select>
<input type=button value=Add onClick="open('popsel.htm','pop','height=200,width=300')">
</form>
</body>
</html>

Hi Guys,

    Thank ypu so much for your helps.

I solved the issues using the Comment from fritz_the_blank on
Date: 11/24/2003 05:50AM PST.

    Sorry NetGroove, I tried the way u suggested before posting this question but it doesn't work. Yo are saying it works for you, probably you would have tested in Netscape, try it in IE, you'll get the same err.

    So I am giving the points to fritz_the_blank!

Thanks & Regards,
Siva
