I've tried to access the value of a selected option through the
following getSelectValue function, passing the name of the select
function getSelectValue (name) {
var sel = document.getElementsByName(name)[0];
var i = sel.options.selectedIndex;
return i == -1? "": sel.options[i].value;
}
getSelectValue ('belongsto')
...
<select name="belongsto" ...
yet I always get the error "sel has no properties". Any idea what's
wrong? Is there a simpler way?

I have an some options like this:
<option value="12345" title="Frank">Frank - 12345</option>
What I want to do, is get the title. I've tried this:
document.MyForm.MySelect.options[document.MyForm.MySelect.selectedIndex].title
That dosn't work. I'm just using the title attribute as a place to hold the information I need. Maybe there is another attribute that would work better for this? How can I get the contents of the attribute?

Code:
<script>
alert("You are not allowed to see this page");
self.location="javascript:history.go(-1)";
</script>
The above script has one option.
I like to make two options(yes or no) like the following.
Code:
<script>
alert("Are you sure to delete?");
Yes(self.location="delete.php");
No(self.location="javascript:history.go(-1))";
</script>
Is it possible? How?

Does anyone know how to get the value from a form option (dropdown list) and have it post the value without having a submit button?
So that when I choose a value in the option list the page is automatically reloaded with that value?

I have a drop down with alot of options say about 6000 cities and
districts. I need to select all options if user selects "All checkbox".
I use "on change" and a for loop to do this, but it takes a lot of time
to select all these options. Is there any faster way to select all
these options?
function selectAll()
{
var element = document.getElementById("location");
var length = document.getElementById("location").length;
for(var i=0; i<length; i++)
{
element.options[i].selected=true;
}
}

I have two drop down box's in a form, how would I go about changing the
options of the seccond one depending on what option is selected in the
first one?
For example, if there's a drop down box with "a", "b" and "c" as the
options, and another drop down box with "1", "2" and "3" as the
options; then when you select "a" on the first drop down box the values
of the seccond one changes to "a1", "a2" and "a3". This should work for
all the options of the first drop down box.

I got this simmple function, It stays on onChange on select and on
change it hides all objects with ID equal to select name plus the
optionvalue. It works perfectly in Opera and FF, but IE crashes because
says that options object is null
the problem is in for (optionId in what.options)
It seems that IE does NOT return the list of options, but only some
other objects: language scrollheight, istextedit, currentstyle,
document, and onmouseup
Please can you help me how can I go throuth that cycle? I need to get
the values of all options in select. Thank you
function showHide (what) {
selectedId=what.options.selectedIndex;
selectedValue=what.options[selectedId].value;
selectedObject = document.getElementById(what.name+selectedValue);
selectedObject.className="";
for (optionId in what.options)
{
optionValue=what.options[optionId].value;
if (optionValue) {
optionObject = document.getElementById(what.name+optionValue);
if (optionId!=selectedId) {
optionObject.className="hidden";
}
}
}
}

I notice when I view the source of a lot of Google pages (for example,
my GMail Inbox page source) that the src option in <scripttags will
refer to addresses like "?foo=bar&bla=bla". How does this work
exactly? Does the server side script return a string containing
javascript code? How does it know which server side script to call?
Does it look for an index file of some type?
Something else I just noticed in the address of this page (I know this
is off topic, sorry)... this page sends GET data to a "place" named
'post', but 'post' has no file extension. How does this work?

I am looking for a javascript code for an html file. I am looking for something where when you put your mouse over the text, a drop down list will come down.
An example would be on a site like www.espn.com - when you put your mouse over NBA the following options appear: NBA Home, Scores, Schedule, Teams, etc.

I am helping someone out with a form. He wants the name required, easy enough, but then only an email or street address required. I have tried a couple of things and it is not working.
I am trying a very simple code:
<script type="text/javascript">
<!--
function validate_form ( )
{
valid = true;
if ( document.contact_form.name_mailing.value == "" )
{
alert ( "Please fill in the 'Your Name' box." );
valid = false;
}
if ( document.contact_form.address_mailing.value == "" || document.contact_form.email_address.value == "")
{
alert ( "Please fill in the 'Your Information' box." );
valid = false;
}
return valid;
}
//-->
</script>
Am I not using the or operator correctly? I only want to have the address or email required, not necessarily both.

I've been playing around with the following code for days already and still in the dark tunnel. Can someone tell me what's wrong with the way I've coded it?
var cell1 = row.insertCell(0);
var selOpt = document.createElement('input');
selOpt.setAttribute('type', 'select');
selOpt.option = document.forms[0].Country.option;
selOpt.setAttribute('name', 'AnotherCtry');
cell1.appendChild(selOpt);
<edit>What I'm trying to do is to copy the options of the Country to another select which I've allowed the users to 'add' to the current row.</edit>

I am wanting to change the option of a select box when a customer clicks on a thumbnail image. code...
When the customer clicks on one of the thumbnails to the left, I want it to change the item that is selected on the right.
How do I do this?
I tried to change the innerHTML and it erased everything in the select box, so I'm quite sure that is not the right way.

I have a select and list of options. I have onkeypress event on the select input. As the user types I am trying to match the entered key strokes to the entries in the options and setting the selected value to the first match.
The problem I am facing is this: My options have 10000,0000, 10001, 1111,0001. Say I type 10, with less than one sec delay I consider them as one unit. So I try to find whether there are any entries in the options which starts with 10 and setting the value. But brower is considering the last entered key stroke , in this example 0 and setting the 0000 which is the first match.
Is there any way that I can stop the browser from doing that or any idea?
Here is the code.

I have a problem: I have to have a footer at the very bottom and I have to have minimal, maximal width options as well. That employs two javasripts. however, the problem is with the footer. The script puts it on the very bottom even so that you can't see it in IE.
You can to scroll down to see it. So, i minimized the height of footer so that it shows up in IE. However, again, there is blank space at the very bottom. Any suggestions how to fix it? I'm no good in JavaScript at all.
