insert HTML <select> value into a textarea - Works in IE6, not in FireFox or Opera
I have a simple form at http://mstramba.com/fb5.html
It''s just a <select> and a textarea.
The idea is to be able to either type into a text area directly or
choose from a list of saved words in the select box. When a new choice
is made from the select, it automatically gets inserted into the text
area.
This code DOES work in I.E6 (on my machine (XP pro), but doesn''t work
in Firefox 2.0.0.4 or Opera 9.0.2
With Firefox 2.0.04, when the page is first loaded, I can choose from
the select control and it works until I type something in the text
area, and then it stops working.
(the <select> is not sending to the text area anymore)
With Opera 9.02, the select control doesn''t work at all.
1) Does prototype do anything "internally" differently for whatever
it''s equivalent of
var txtNode=document.createTextNode(selectValue);
var textArea=document.getElementById(targetTextArea);
textArea.appendChild(txtNode);
is ?
2) Should I be using some other way of accessing the textarea other
than the "appendChild" method?
Any other ideas appreciated.
Mike

Re: insert HTML <select> value into a textarea - Works in IE6, not in FireFox or Opera
why are you creating a textnode? just grab the text from the text area,
append the new word and update the textarea? (just a guess actually
I''ve
never tried to do what you are doing...
with prototype it might be as easy as<select
onchange($(''target_textarea_id'').value =
$(''target_textarea_id'').value +
this.value)
but i''m not a JS expert and I only started on pt this week..

When a new choice > is made from the select, it automatically gets inserted into the text > area.Using onchange with a select element has usability issues - try using the keyboard to change selections in various browsers. Consider: <form action=""><div> <textarea id="ta"></textarea> <select onchange="this.form.ta.value=this[this.selectedIndex].text;"> <option selected> <option>bar <option>tin <option>can </select> <input type="reset"> <input type="submit"> </div></form>> This code DOES work in I.E6 (on my machine (XP pro), but doesn''t work > in Firefox 2.0.0.4 or Opera 9.0.2 > > With Firefox 2.0.04, when the page is first loaded, I can choose from > the select control and it works until I type something in the text > area, and then it stops working. > (the <select> is not sending to the text area anymore) > > With Opera 9.02, the select control doesn''t work at all. > > 1) Does prototype do anything "internally" differently for whatever > it''s equivalent of > > var txtNode=document.createTextNode(selectValue); > var textArea=document.getElementById(targetTextArea); > textArea.appendChild(txtNode);It is better to use textArea''s value attribute rather than append a text node.> > is ? > > 2) Should I be using some other way of accessing the textarea other > than the "appendChild" method?Yes, just get/set the textarea value.

You need to explicitly get the value or text attribute of the selected option(s).
