This is a great script but how do I

JavaScript
1

Here’s the script:


<script language="javascript" type="text/javascript">
function addtext() {
	var newtext = document.myform.inputtext.value;
	if (document.myform.placement[1].checked) {
		document.myform.outputtext.value = "";
		}
	document.myform.outputtext.value += newtext;
}
</script>

<form name="myform">
<table border="0" cellspacing="0" cellpadding="5"><tr>
<td><textarea name="inputtext"></textarea></td>
<input type="radio" name="placement" value="append" checked> Add to Existing Text<br>
<td><p><input type="radio" name="placement" value="replace"> Replace Existing Text<br>
<input type="button" value="Add New Text" onClick="addtext();"></p>
</td>
<td><textarea name="outputtext"></textarea></td>
</tr></table>
</form>

This script is going to work great in conjunction with my PHP script however the problem is with the “Add to Existing Text”.

If I have three lines such as:

Apples
Bananas
Oranges

And I "“Add to Existing Text” which has “Strawberries, blueberries” it does so in this fashion:

Strawberries
blueberries Apples 
Bananas
Oranges

As oppsed to:

Strawberries
blueberries 
Apples 
Bananas
Oranges

Does anyone know how to add that <br /> at the beginning if text is being added?

<script language="javascript" type="text/javascript">
function addtext() {
   var newtext = document.myform.inputtext.value;
   if (document.myform.placement[1].checked) {
      document.myform.outputtext.value = "";
   }
   
   var outText = document.myform.outputtext;
   outText.value += outText.value.length > 0 ? "\
" + newtext : newText;
}
</script>

Thanks guys, much appreciated. Since were on the topic would it be difficult to make the first instance without a "
". The reason is that if the new textarea is blank it adds a blank space in the first entry. As I’m using the information in this form I’ll have to restructure everything if the first entry is blank.

document.myform.outputtext.value += 
((document.myform.outputtext.value)?'\
':'')+newtext;

Yes, I think this is a better idea, mostly because if you did manage to add a br, you’d get

<textarea>Strawberries<br/>blueberries<br/>Apples<br/>Bananas<br/>Oranges</textarea>

I don’t believe you can have tags inside a textarea element, and if you can, they should be interpreted as plain text (cdata), not real br’s.

How about using a new line escape sequence, "
"?


document.myform.outputtext.value += "\
" + newtext;
