Multiple Variables In A Drop Down List?
Jul 1, 2011
I am creating a quote calculator as a mobile app using the JQuery Mobile plugin in Dreamweaver CS5.5. This supports HTML5 & Javascript.
I have included a drop down list in which the user selects a specific Annual Volume. I have 2 different calculations that need to be done based on the users selection. Different calculations meaning that I need 2 different number values assigned to the option.
For Example:
Calculation #1 (I'm calculating what the Run Quantity is based on what the user selects as the Annual Volume. If user selects an Annual Volume of 150,000 then the calculated result for Run Quantity needs to be 3500)
HTML for this scenario:
<li data-role="fieldcontain">
<p><span class="ui-listview-inset">Annual Volume:</label>
<select name="annualvolume" id="annualvolume">
onChange="Calculate();">
[Code].....
Currently I am simply having the user enter the annual volume twice so I can do the 2 calculations, but this is really clunky and not ideal.

I have a table that has parts with multiple characteristics. Part Number, Height, Width, Capacity, Price, Etc. I would like to have a drop downs for all of these values, when a user selects one of these values it will filter the results into a list. Ex. user selects a part that has a Height of 6 and width of 10 it will only list those parts. As I said earlier, I have a script that will give me all the parts, however I am not able to make the onchange list parts with multiple values.

I was wondering how you would list multiple variables after a equal ==?
Example....
if ( pathname == schoolinformation, chaplainchatter)
$('#button_newspress_archive,#button_tech_college,#button_parent_portal,#button_transition_portal,#button_6th_form,#button_connect,#button_vacancies,#button_vle_login').css('display', 'none');
$('#school_information_sub').css('display', 'block');
if ( pathname != schoolinformation, chaplainchatter)
$('#school_information_sub').css('display', 'none');
Or even list multiple URL's within the variables?
Example
....
var schoolinformation = '/st-paul-s-website/school-information/school-news/headteachers-headlines', '/st-paul-s-website/school-information/school-news/chaplain-chatter-headlines';

I am trying to create a drop down list which depend to the value selected from the previous drop down list. I can add it without problem, but If I change again the value of the first drop down list I would like to remove the previous drop down list generated from the first value. If I try to remove it when I create the element, it even does not create the element, the remove element function seems to work because when you click on the remove link it works.

I am asking jQuery to tell me which drop down option is selected in a drop down list - like this:
I would like to check if this was successful before I proceed. What are the possible return values for this statement?
If no id exists.
If no option is selected.
If some other problem occurred.
In these cases am I expecting a null return; an undefined return, a false return value?
And, based upon the complete set of return possibilities, what would be the best and most comprehensive tests I could apply to cover every base.

I have a page that displays a list of people playing in a tournament. I need to be able to generate a Leaderboard based on which players are manually selected by the admin. Next to each person there is a drop-down list. An admin can go in and select a "slot" that a player should be in on the leader board from 1 to 8, or leave it blank if none. What I need to figure out how to do is the following, when a change event happens on a drop-down list, and say the value 5 is selected, I need to check to make sure that 5 is not already selected in one of the other players drop-down lists, in other words, that the 5th leaderboard slot is not already full. if it is, display an error message and make them change that one first. how to do that with jQuery? I'm thinking it will have something to do with the each() function, but not sure exactly how the logic should work.

I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.This piece of code is working well . . . .
<?php
$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error());
mysql_select_db('mydatabase') or die('Could not select database');[code]......

I've been beating my head against a wall for a few days trying to get this working. I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:

I am planning on using the maito form with Javascript. I have a form and it is structured in the following fashion:
<form>
<b>Subject </b> <input type="text" name="subject" size="30"><br>
<b>Person 1 <b><input type="checkbox" name="email" value="person1@email.com"><br>
<b>Person 2 <b><input type="checkbox" name="email" value="person2@email.com"><br>
<b>Person 3 <b><input type="checkbox" name="email" value="person3@email.com"><br>
<input type="submit" onclick="submit">
</form>
What I am trying to do with Javascript is that you fill out the subject name and then you select which recipients of email you want to receive the email. So if I select Checkbox 1 and Checkbox 3 then when I click submit, it opens my Outlook and the To is filled in with person1@email.com;person2@email.com. So I guess I would need the javascript to populate and <href mailto: form after checking which names are checked and then populating the mailto with the variable that contains the list of names I chose. Right now we have a clunky method using the mailto but I don't have the option of choosing who it mails to so when I send it, I send the mail to everyone, even those on vacation.

iam trying to use 5 drop downs in my form for user to select languages and each select drop down should not allow the user to select the same language again and all my drop downs are populating individually from the DB on the page so if "English" is selected for "dropdown 1" then again "drop down 2" should not allow "English" to be selected.

Is it possible to assign multiple variables at once? For example:
var int1,int2,int3,int4,int5 = 0
I'm just wondering because I did this without thinking and my program never gave me an error and everything worked fine. Is it because these variables are set to 0 by default or what? If it does work, are there any other languages that this works in such as vbscript?

I'm trying to pass multiple variables using a url on a Java function call.
the code I have that passes the 1 variable is:
function HandleChange() {
parent.CustomerIf.document.location.href="CustomerReturn.asp?id=" + varName.options[varName.selectedIndex].text;
}
which passes the chosen data (being loaded from a database) from a drop down box on an onchange event in asp script.
What I want to do is pass multiple variable via the above url script that the next page will get by the request.querystring method.
something like this:
function HandleChange() {
parent.CustomerIf.document.location.href="CustomerReturn.asp?id=" + varName.options[varName.selectedIndex].text + "address=" varAddress.value;
}

How can I create a Javascript drop down list File? I want to have a webpage that contain a dropdownlist. But i want the items and values of that drop down lists to be stored in a seperate javascript file, So that my webpage call that JS file whenever user click on the DDList.
Basically what i am interested in is to place all my drop down list Items manually in the javascripting file and then on the main page there will be links from alphabet A-Z so when the user click on alphabet A the dropdown list will only show the containing items start with alphabet A....
Hope this makes sense!! The reason why is because there is a long list of items and i dont want to put them inside my page.

I'm having a problem passing a variable through a URL because the
variable is supposed to hold a URL that has a variable of its own.
Here is an idea of what I'm trying to do:
href="javascript:
newWin('/vcrc/exitvcrc.jhtml&newURL=http://www.something.net/default.asp?sponID=ETC','NowLeaving',駼',
餠', 'no', 'auto','no');"
So, pretty much, the page I'm sending the variable to think there's two
variables (newURL and sponID), but sponID is part of the URL.

I'm trying to pass data to my mySQL database, but I'm doing that 2 jQuery scripts:User comes on my page where there is a list with some values, e.g 530, 532, 534 etc etc ..User clicks on one of them, this link is using the jQuery to get another php file which get's the data from my DB and list it below the first list, here's the code for this:
$('#letter-e a').click(function(){
$.get('e.php', {'depot': $(this).text()},function(data){
$('#dict').html(data);
[code].....
So the second list is another step that can't be avoided to get the final result. In other words, i'ts another list where the user has to chose one of the items from the list to see the final result, I've added this code inf the 'e.php' file:
$('#letter-f a').click(function(){
$.get('f.php', {'date': $(this).text()},function(data){
$('#entry2').html(data);
[code].....
The problem is that my 'f.php' only gets 1 variable value, but I'll need 2 or more (maybe in the futur), how to pass multiple variables to a php file using jQuery?

I'm using AJAX to, on the click of a button, run a PHP script that dynamically generates a new line of text, and passes that to the script.The PHP script, new_sentence.php, just echos out the sentence.This works fine.But what I would like to do is for the PHP script to dynamically change JavaScript variables.how to pass multiple variables from PHP to JS.I can, of course, pass one by having the PHP script echo anything, and then use JS to set the variable to the PHP output. But what if I wanted to set two or three JavaScript variables at once?Here's my code in the HTML page that contacts new_sentence.php:
Code:
function ajaxRefresh(){
var ajaxRefresh;
ajaxRequest = new XMLHttpRequest();[code].....
When I press the "Refresh" button on the HTML page, it runs the ajaxRefresh function, which calls new_sentence.php. Then, once it gets the response, it changes the text of the element named "div" to whatever text the new_sentence.php echos.I'd like to figure out how to get a couple of variables.I would imagine this is simple. how to set the variables in PHP and then how to retrieve them in JS.

Is it possible to pull multiple variables from a single dropdown menu selection?
Example:
I have this:
function material_choices_menu() /* Provides Specific Gravity for various materials */{
var data = "Material <select name='material'>";
data += "<option value='.926'>CYCOLAC MG47 (ABS)</option>";
data += "<option value='1.050'>CYCOLAC MG47MD (ABS)</option>";
data += "<option value='.958'>CYCOLAC T (ABS)</option>";
data += "</select>";
document.write(data);
}
I'd like to have multiple option values:
function material_choices_menu() /* Provides Specific Gravity for various materials */{
var data = "Material <select name='material'>";
data += "<option value1='.926', option value2='.005-.008'>CYCOLAC MG47 (ABS)</option>";
data += "<option value1='1.050', option value2='.005-.008'>CYCOLAC MG47MD (ABS)</option>";
data += "<option value1='.958', option value2='.005-.008'>CYCOLAC T (ABS)</option>";
data += "</select>";
document.write(data);
}
I plan to use the first value in some math formulas to determine weights and the rest of the values will just be shown as data for the user and/or possibly a link to the datasheet for the material selected.

I'm new here, and new to js. Here is my problem: I have written out a code to make an image switch from state 0 to 1 and back to 0 again (an eye blink). The code works fine, but I would like to write the functions with arguments so it could be applied to more images. I have tried for a few hours (and searched forums) and am getting no where. Here's my code.
Code:
function home_blinkDown()
{
//alert('blink down');
var t = setTimeout("home_blinkSwap('home_js', 'images/main/home_blink.png')", 2000);

I've recently begun using AJAX on my website and have ran into a problem.My webpage: catalogue.php contains a category variable named $cid which the page GETS in order to display products from the correct category. This works fine.I now want to implement a drop-down box to sort by price, name, newest etc...I have tested the AJAX out with a dropdown box for changing the category and it works fine, this is because it is only passing one variable which it gets via the javascript "this.value".
The sort by price box requires two variables to be passed .I can pass the "this.value" which tells the javascript function I want to sort by price/newest/etc but I cannot figure out how to pass the category variable ($cid) so that when the xmlhttp.open calls the url: getSort.php it passes both pieces of info.My javascript is:
Code:
function showSort(str)
{
var cat = <?php echo $cid ?>;[code].....

I would like to use a control on a WebForm that acts like an editable
DropDownList control. The user should be able to select a value from
the list of choices, or type in a new value if no predefined choice is
applicable.
It doesn't appear to me that a DropDownList control is editable.
How would you suggest I accomplish what I want to do?

I have what I think is a fairly simple problem, but I cannot figure
this out. I have a SELECT object on my page. When the user performs
a certain action, I want the focus to be placed in the drop-down field
AND the actual list of drop-down objects to appear (i.e. simulating
that the user has clicked in that field). Ideally, of course, the
currently selected entry should be highlighted. Listed below is a
snippet of sample code. If the focus is currently in the text field
and the user clicks on the "Test" button, I would like the entire
drop-down menu to appear. I have not had any success with the
"fireEvent" method or the "click" method (only "focus" seems to work). Code:

The last two lines of the following code is not setting the value of the selector unless i debug it within firebug. when I set a breakpoint on those two lines it shows the val in the parentheses and it will set them correctly, but if I do not debug the script then it doesn't set them.
populateLists: function(executionLevel, contractor, program) {
var _chart = this;
$.each($('select#contractor option'), function() {
