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 have a bit of a question about CGI...I'm not very knowledgeable about it, so I have a specific question. Can you set up a site in which sites can be rated using CGI?
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; }
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?
<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.

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;
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.
In JS, how can I change the selected value of a dropdownlist(select options) I know the value of indexed value of the selected value before it is changed.

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'm working on a small scrolling popup window that mimicks an instant message window. I've currently got it all set up and working however I would like a way to have multiple var html_code options that can be picked at random. For example, each option would have a different image and text in the box.
What I'm after or trying to do is simply create a script to launch a new page after a X amount of time, like a popup. But I need the new window to have the following options like no toolbar or scroll bars etc... This is the code I've been trying to manipulate for my purpose and just can't get it right meaning it doesn't work at all in fact I haven't even been able to get the timer part worked in since I couldn't get the launch part working..... I've made a web app using asp.net & vb.net and need a launch page so I don't have any toolbars or scrollbars etc....
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 currently have two selectbox, the first for categories and the second for subcategories. When an option from the category selectbox is chosen I would like the subcategory selectbox to be filled with options drawn from an array.
The following code I have works for Chrome and Firefox but not in IE, I would appreciate any help to fix the code or new code which does a similar function.
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>
