Adding Options To A Select Box?

Jul 30, 2010

I've searched the web and every tutorial I can find says the same thing, and I am doing what they say, but it's inexplicably not working. Basically, I'm using a nested object to populate a select box using the new Option() method. Unfortunately, when I include the new Option line, it breaks the loop and does not add anything.

Creating/adding Options To Select Lists?

Nov 11, 2010

I'm trying to create/add options to select elements in a form. My form has several select elements, only first is actually populated and visible. Each select element is on a seperate table row. Depending on the option chosen in the first select list, another row (select element) becomes visible which is then populated depending on the option chosen. I accessed the select element and created the option(s) using this format

Adding Listbox Options To Multiple Textboxes?

May 6, 2011

I am resorting to you for help with a html form that uses javascript to validate data. the form is an invoice for a trip order where the user can select a trip location out of a listbox, a number of people traveling, and where they wish to stay(ex. hotel, tent, etc.) after the user selects one for each category and hits the "add to invoice" button, the fields in the invoice should get filled with the corresponding information. Now my question is how can I write code that will insert information in the next row down after the previous row has been filled? basically what logic and programming structure do I need in my function that will know when the first row in the invoice is filled. I'm struggling at the part where when the "add to invoice" button is clicked. some data is added to the invoice, and if the user wants to book another trip, the second trip should be appended in the second row of the invoice. what is happening in mine is that whenever I book another trip, the first one gets overwritten when in fact it should be left intact and the data should get appended in the next row down.

</head>
<script type="text/javascript">
function addit()

Adding Function To Main Button To Check / Uncheck All Options

Jul 21, 2011

I'm using dreamweaver cs5 and I have created a page that have a table that can check or uncheck certain option in each row..in every column, there is a main button ('m planning to add function in the main button to be check all or uncheck all - but I did not managed to do it right...there are errors)

For example:
Pulau Pinang button, when user click, it will check/uncheck all option under Pulau Pinang...same goes to other columns. After selecting their option, user can submit their option using submit button (option chosen can be in different columns). My problem is, my submit and reset button is not functioning besides, I'm not able to make the main button to check or uncheck all option..

Below is my coding for reference:
PHP Code:
<!DOCTYPE ...> <html ...> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title> <style type="text/css"> body { 
background-image: url(images/crop.jpg); margin-left: 130px; margin-top: 60px; 
margin-right: 130px; margin-bottom: 100px; background-color: #FFF; 
} body,td,th { font-size: 14px; color: #000; } </style> <script type="text/javascript"> function MM_swapImgRestore() { 
//v3.0 var i,x,a=document.MM_sr; .....

I've tried also using below code for check all/uncheck button but it doesn't work:
PHP Code:
<form name="myform" action="checkboxes.asp" method="post"> 
<input type="checkbox" name="check_list" value="1">ASP<br> 
<input type="checkbox" name="check_list" value="2">PHP<br> 
<input type="checkbox" name="check_list" value="3">JavaScript<br> 
<input type="checkbox" name="check_list" value="4">HTML<br>
<input type="checkbox" name="check_list" value="5">MySQL<br> 
<input type="button" name="Check_All" value="Check All" onClick="CheckAll(document.myform.check_list)"> 
<input type="button" name="Un_CheckAll" value="Uncheck All" onClick="UnCheckAll(document.myform.check_list)">

Replacing SelectBox With Another SelectBox?

Aug 3, 2010

My code (below) works if I place the selectBoxes in different cells on a table. However, what I want is only ONE selectbox displayed at a time, not the 3 different select boxes in 3 different table cells of the table.

I initially want the citySelect to display, but if user clicks option [-- change country --], then the citySelect is REPLACED by the countrySelect. Then, on making a country selection, the countrySelect is REPLACED by a new citySelect which is populated with the new city list.

Code:
<script type="text/javascript">
<!--
function loadCities(countryID){
if(countryID == "") {

Workaround For SelectBox Under IE - How?

Feb 6, 2007

we probably all know the problem that select boxes under IE are always
overlap DIV layers. Afaik there are two workarounds:

1. hiding the select box
2. IFrame beneath the DIV layer

But I don't know how to do that.

We want to show a DIV layer as tooltip.
The DIV layer has no defined size (neither a width nor a height
attribute). The size depends on the text the user defined for the tooltip.

My questions:

1. How can I know when the tooltip is 'over' a select box, so I can hide it.

2. How can I define an IFrame that has the same size as the tooltip,
when I don't know the tooltip's size?

Val() For Selectbox Not Linking Correctly?

May 12, 2010

I'm using the niceforms plugin to style my select box. The problem I'm having is that I can't get the right javascript code to activate the links placed in the value option.

el.lnk._onclick = el.onclick || function () {
if(this.ref.oldClassName == "NFOnChange") {
//insert your code here
}};

This is my attempt at manipulating the code to allow url linking in the select drop down

el.lnk._onclick = el.onclick || function () {
if(this.ref.oldClassName == "NFOnChange") {
//code i added
window.location.href = $(this.ref).val();
}};

The PROBLEM is the links do not work as expected, they do not link to their corresponding values.

form class ="niceform"
select class ="NFOnchange"
option value = "http://link1.com" -> link1.com
option value = "http://link2.com" -> link2.com
option value = "http://link3.com" -> link3.com

i just need to insert the right bit of code to make the links correspond to their option values.

External Script Can't Modify Selectbox On The Fly

Jul 17, 2009

External script can't modify selectbox on the fly

HTML source:

externalGetOptions.js

The script in externalGetOptions is basically ok (as I call it directly in the html source (when I place the code in the script section in the HTML-source) everything works fine). Point is that this piece of script in the HTML source is built on the server side and need to be in an external js-file. So it needs to be an onclick event.

Message I get: document.formA is undefined.

I assume he can't find the select element.
