returning multiple checkbox values to textarea

staffa · Feb 1, 2005

Hi

I've made a script that generates a popup window with checkbox options that onclick gets send to a textarea on the opener page and it works, but the problem is that the checkbox values overwritte eachother when they are passed to the textarea.

Here is my script:

Code:

function check(){
infoservices = document.forms[0].elements
inp_services = self.opener.document.form_tilfoej.inp_services
txt=""
for (i=0;i < infoservices.length; i++){
if (infoservices[i].checked){
txt = infoservices[i].value
}
inp_services.value = txt
}
}

I hope someone can help.

staffa,

Try this.
[tt]txt [red]+[/red]= infoservices.value
[/tt]

With better format like line separator or else, like this.
[tt]
txt += infoservices.value + "\n";
[/tt]

Hi tsuji and thanks for your quick reply.

I'm not able to use "\n" because the script is generatet by another script:

generator.document.writeln('txt += infoservices.value');

Do you know a way to get around that problem?

Thanks.

staffa,

This would do?
[tt]
generator.document.writeln('txt += infoservices.value'+'<br />');
[/tt]

Or this - I don't see quite clearly your setup, but for textarea eventually it has gone to, this might do.
[tt]
generator.document.writeln('txt += infoservices.value'+'\n');
[/tt]
(Do not see why you raised a concern previously, but try it.)

Thanks again, but it still doesn't work.

The generator makes a popup with a form full of checkbox options and the script to handle the form and pass the values to the opener page, so when the generator reads the \n it makes a line break in my script in the popup.

Hope that make sens

staffa,

To pass to the textarea, it would be this, I think after looking more closely your description.
[tt]
generator.document.writeln('txt += infoservices.value'+'[COLOR=red yellow]\[/color]\n');
[/tt]
wiht "\" escaped.

Clearing up the quote misplaced! (what a mess!)
[tt]
generator.document.writeln('txt += infoservices.value+"\\n"');
[/tt]

This is a quick & dirty demo.

Code:

<html>
<head>
<script language="javascript">
function winopen() {
	var owin=window.open("","popup");
	with (owin.document) {
		writeln("<html><head><script>");
		writeln("function mopup() {");
		//simplified version, unrelated to checkbox status
		writeln("self.opener.txtarea.value='a\\nb\\nc'");
		writeln("self.close();");
		writeln("}");
		writeln("<\/script><\/head><body><form name='abc'>");
		writeln("<input type=checkbox name=chkbox value='a'>a<\/input>");
		writeln("<input type=checkbox name=chkbox value='b'>b<\/input>");
		writeln("<input type=checkbox name=chkbox value='c'>c<\/input>");
		writeln("<button name=closewin onclick='mopup()'>close<\/button>");
		writeln("<\/form><\/body><\/html>");
	}
}
</script>
</head>
<body>
<button name="makewindow" onclick="winopen()">select checkboxes</button><br />
<textarea name="txtarea"></textarea>
</body>
</html>

Escaping the \n works great :-D
I've tryet to find this solution with the \n for days, because the real thing is that it's a javascript in a javascript in a php script, and thats why it was a bit difficult for me

Big thanks again.
