How to access name value pairs from a <select>?

Say I have:

<select>
<option value='a' > First
<option value='b' > Second
<option value='c' > Third
</select>

Is there a way I can access the values First, Second and Third from
an array ? I want to write a javascript function that can
automatically select one option based on a regular expression match
of First Second or Third.

Get the .text property of the select. It will give you the First, Second
and Third that you are hunting.

So, loop through the select list checking it's .text property and then
when you find it, set the selectedIndex of the select list to the one
that corresponds to the .text property you want.

function setSelect(txt){
var sel = document.myForm .mySelect;
var selLength = sel.length;
var found = false;
for (var i=0;i<selLength ;i++)
{
if (sel.options[i].text.toLowerCa se() == txt.toLowerCase ())
{
sel.options.sel ectedIndex = i;
found = true;
break;
}
}
if (!found){alert( 'That entry not found')}
}

With this HTML:

<form name="myForm">
<select name="mySelect" >
<option value='a'>First
<option value='b'>Secon d
<option value='c'>Third
<option value='d'>Fourt h
<option value='e'>Fifth
<option value='f'>Sixth
<option value='g'>Seven th
<option value='h'>Eight h
<option value='i'>Ninth
<option value='j'>Tenth
<option value='k'>Eleve nth
<option value='l'>Twelf th
<option value='m'>Thirt eenth
</select>
<input type="text" onchange="setSe lect(this.value )">
</form>

Simply call setSelect with the text you want searched for.

No, but you can read it from a collection. RTFFAQ.

No,


Sure you can.
but you can read it from a collection.
You can get it that way also.

As should you. And, read posted code before you babble your BS.

Now, is that a signature or not?

Hello, I am used to using the label tag with check boxes and radio buttons in html forms. This allows me to click on the text of the label to activate/deactivate the check box / button, rather than having to click on the (possibly small) box or button. I recently tried to assign a label to a select "drop down list", but found that when I clicked on the label text to bring it into focus, the select box was reset to the first entry. ...
