Dynamically Adjust <SELECT>
Aug 10, 2005
Here's what I'm trying to do: I've got a <SELECT> box followed by a text <INPUT> field, and I want them to change each other. The select box lists a whole list of cities and also "Other", while the text box is labeled "Other." When a user selects anything at all EXCEPT "other" in the select box, I'd like it to clear whatever value is in the textbox. And when a user starts typing in the text box, I'd like it to dynamically select "other" from the textbox. Is this doable? Code:

I have a div in my webpage that I want to resize to the size of the browser. Does anyone know of the right tag to do this?
I have theNode.style.top at 0 pixels and theNode.style.left at 0 pixels. Also right now I have theNode.style.height=770; and theNode.style.width=1255; I want these two sizes to be dynamic to the browser width.
function doMessage ()
{
createGreyLayer();
t=setInterval("fadeDown()",50);
}

I want to integrate a forum (phpbb) inside my custom made website. The problem is that there is no way to dynamically adjust the iframe height..I thought javascript would be the best way to do that, the problem is that i know nothing about JS... Here is my idea,
-2 scripts, 1 in the parent page (the one with the iframe tag) and the second one in the main forum page
-The script inside the parent page, would dynamically set the "height" parameter inside the iframe tag based on a value passed by the second script.
-The second script, inside the forum page, would read the entire content of the (document.body.scrollHeight) current page and sends its result to the first script.I have found a script that was supposed to do that, but for some reasons it doesnt work very well. Here is the link where i explain de problem with it: http:[url]....

I have tried some css & html methods to place the footer at the bottom of the page no matter at which height it will be after the javascript files will run. But I cannot do it.I tried then to adjust the position of the footer dynamically after the window has loaded and the footer is placed indeed at the end of the document, but if the document gets bigger, the footer doesn't go lower.Specifically:FILE html_test.html
HTML Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.
Trying different options I came out with this approach that seems to do the job so
far:
function setSelect(pID,pSelectedValue)
{
$('#'+pID + ' option:selected').removeAttr('selected');
[Code]....

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.

Take the following:
I want fill a select list with the first list on page load, then depending on which option is chosen, fill another select list with the appropriate list. I'd prefer using only javascript!

Each time I dynamically load the options of a select box and then try to do anything with it (such as clicking it or using other JS code on it) I get the following Firefox error:Error: Index or size is negative or greater than the allowed amount = NS_ERROR_DOM_INDEX_SIZE_ERR
I am using the following code:<select id="day" name="day"></select>
<script language="javascript">
var options_list = new Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31);
selectbox_element = document.getElementById('day');
selectbox_element.options.length = 0; // Remove any previous values.
for (var i = 0; i < options_list.length; i++) {
selectbox_element.options[i] = new Option(options_list[i], options_list[i]);
}
</script>
The "options_list" array is filled beforehand using a simple PHP for() loop.
If I create the exact same options but do so by writing them into the HTML using PHP, then I don't see the error message anymore.
This problem happens in both Firefox 1.5 and Internet Explorer.

I have a drop down box on a site, and when an option is selected, I need the value of a text box to change.
My form has the following in it:
<select name="event">
<option value="" onclick="updateprice(0)">Please Select..</option>
<option value="3" onclick="updateprice(25)">Monday 16th February 2004 (£25 per ticket)</option>
<option value="2" onclick="updateprice(20)">Saturday 28th February 2004 (£20 per ticket)</option>
</select>
and I have this javascript function:
function updateprice(theamount) {
document.nonmember.adminprice.value = theamount
}
the form is called 'nonmember' and the text box i need to change is called 'adminprice'.
Everything works fine in mozilla, but in IE nothing happens when I select an item from the drop down list (not even a javascript error)

I have a select list which has a couple of colour coded items on it. The color is added via a style attribute as this is read from a database table that contains the agency details and 'color code'. Here's how that looks:
Code HTML4Strict:
<select name="agency" id="agency">
<option value="" selected="selected">Select Agency</option>
<option style="background-color: rgb(179, 253, 196);" id="agency4"
[Code].....
it always tells me that the background-color is rgb(51,153,255). I believe that may be the blue color that a selected item has by default.
So, my main problem is that no matter what I try here (and I've been trying for the past couple of hours) I can't get the background color from the style attributes on those two select items that have the different background-color.

I would like to have a jsp page with a form consisting of several inputs and selects. When page loads for the first time, there is only one select (with values taken from database), but after clicking on link "add", the subsequent selects are added (using JavaScript and DOM). It seems to be pretty easy task, but I'm not sure how to populate the newly created select with data.

I have a function that dynamically creates a new div, part of the function looks like:
root = document.getElementById('rootbox2');
var oDiv=root.appendChild(document.createElement("div"));
with(oDiv){
id=ji;
className="workshopRow";
setAttribute("attending","");
setAttribute("attending_count","0");
}
var oText = oDiv.appendChild (document.createTextNode(""));
var oDiv1=oDiv.appendChild(document.createElement("div"));
with(oDiv1){
className="workshopName";
}
var oText = oDiv1.appendChild (document.createTextNode(""));
var oSelect=oDiv1.appendChild(document.createElement("select"));
with(oSelect){
name="select_"+ji;
id="select_"+ji;
className="workshop";
onchange="calc_subtotal("+ji+")";
}
var oText = oSelect.appendChild (document.createTextNode(""));
var oOption=oSelect.appendChild(document.createElement("option"));
with(oOption){
value="12";
setAttribute("price",10);
}
What I am looking to do is add an onchange event to the select element, not sure if i have programmed it correctly but it does not seem to work.

I am creating a dynamo form but <select and <option does not show.
How do I make sure that they are created on the fly?
jQuery("#dump_data_box").append('<select id="thisid" name="value_name[]">');
and later
jQuery("#dump_data_box").append('<option');
///
if (v==k2) jQuery("#dump_data_box").append(' selected ');
//
jQuery("#dump_data_box").append(' value="'+k2+'">'+k2+'</option>');
But they do not show in the <div>.

I need to pass the selected option of a <select> tag into a query
string, so that the page is reloaded with the selected option already
chosen. This will occur with the onclick() event hander, and the query
string will be processed using a server-side technology. I'm just not
sure how to word the "onclick" handler. Here's what I have:
<select id="StartMonth" name="StartMonth" onchange="location.href =
'thispage.cfm?StartMonth=_______'">
What is the correct wording to set the underlined portion to whatever
was selected? I know it has to be done with JavaScript, since the
decision is made on the client-side.

The code below works great in Mozilla.
In IE the selection box is created, and there is a drop-down box if I click
on the down arrow, but I can't see the OPTION text for each option. The
options are invisible, yet the box seems fully functional. I went into the
debugger and sure enough the selection box has "OPTION" child nodes with the
correct "value" and "text" attributes.
What could be wrong?:

I'm currently working with a bit of javascript to dynamically add
<option>s into a select box. My code currently works fine in Internet
Explorer, however in Firefox the dropdown only displays the first
option in the list, and when clicked the other values aren't displayed.
Here is the code;
//ar_options is an array with the option to be displayed in.
for (count=0; count<number_of_options+1; count++)
{
document.forms['enquiry'].enquirytype.options[count] = new
Option(ar_options[count],ar_options[count]);
};
As I said - fine in Internet Explorer, but not in Firefox. I did
discover some discussions about this, which were talking about an issue
and workarounds but I couldn't get any of them to work. I have also
tried simply using the document.write() function to output the HTML in
the correct place. However this is just hte same, works in IE but not
Firefox.

I have 3 select pulldown boxes where a user will select a year (either
2002 or 2001), a week (one thru 52), and a database (short data or long
data). But if a user selects a week that is less than 4, the 3rd select
pulldown will only show the choice of "short data", as they will not be
able to select "long data". Is it dynamically possible in javascript to
program a third pull down in this fashion?

I have a form where a user enters a number in a text box (txtTickets). When that number is entered, I need to create an equal number of select boxes. I've found code examples which show how to dynamically add or delete options from a select box, but I have found no examples which deal with this specific scenario. The select options do not depend on user input -- that is, I do not need to populate it dynamically. I need to create them dynamically. Has anyone created something similar to this?

I built a reusable plugin for slideshows. Client now needs me to add something that will affect its reusability.The line below is a snippet which is attached to a nav button. Each slideshow has a dot per slide. When clicked I get the number of sibling that it is within the group and then I look UP the DOM to the nearest div with the class called 'slide_holder'. I then display the slide that has the same sibling number as the dot(In other words - If you click the second dot in the group of dots, then the second slide will fade in. If you click the 3rd dot, then the 3rd slide will fade in)Below is a snippet (CLICK HANDLER)
$('.slider_dot').click(function() {
$(this).parent('.slide_dot_holder').prev('.slide_holder').children().fadeOut('slow');
$(this).parent('.slide_dot_holder').prev('.slide_holder').find('div:eq(' + $(this).index() +

I am having trouble writing this javascript for my work, normally I would do this in ASP or PHP, but the environment I am working with will only allow javascript for dynamic function.
The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. code...
