Use A For Loop To Create Drop-down List?

May 9, 2009

I'm trying to add <option> elements to a <select> list. It isn't going too well! The option elements are years from 2004-2013. My code below successfully increments my year variable, but I'm obviously going awry with how I'm writing to the document. At the moment I get 10 separate select boxes instead of the single select list containing the 10 options for each year.

Removechild - Create A Drop Down List Which Depend To The Value Selected From The Previous Drop Down List

Jul 28, 2010

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.

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:

Create A Drop Down List With States?

Dec 10, 2010

I have a question about the best way to execute this task. I am trying to create a page with a dropdown list where the user selects the state. A drop down list below that can have the specific schools to that state to choose from. Now I need a way for the user to click on a school and then be taken to a page that has website URL's from all the fraternities in that school.

Do I need php and mysql? I don't want to create a million pages unless I have to. What is the easiest way to do this. Maybe some kind of central form things where it outputs the fraternity you want at a particular school and state. Also I am using tumblr but can just link it to a normal html or php page just throwing that out there.

JQuery :: Null - Undefined - Empty - Drop Down Option Is Selected In A Drop Down List ?

Oct 25, 2011

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.

JQuery :: Limit If A Value Can Be Selected In A Drop Down List (select) Based On Other List

Jun 9, 2009

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.

PHP Drop Down List Selection Populates Second Dropdown List Or Text Box?

Jul 13, 2011

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]......

Jukebox - Replay List And - Create Non Dropdown List ?

Sep 1, 2010

I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: [url]

I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below:

1.How can I have the Jukebox cycle through all tunes and then start over from the beginning?

2.How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the users selection and then play all songs to the end. Then as in #1, start over from the beginning?

Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a playlist from the drop down.

Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to.

The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.

Go to url removed and click on the link that says:

Jukebox utilizing an .m3u playlist:

Here is the .m3u playlist for the above code:

The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.

Go to url removed and click on the link that says:

Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc¶

How Can I Create These Variables In A For Loop?

Dec 11, 2005

What about if I had something like this where a for loop creates all the variables for you...rather than having to write them out on individual lines like so:

for(i = 0; i < myForm.elements.length; i++) {
tempControl = myForm[i];
var e = tempControl.name;
var [e] = document.myForm[e].value;
}

As oppose too:

bodyChooseColour = document.myForm.bodyChooseColour.value;
bodyChooseFont = document.myForm.bodyChooseFont.value;
bodyChooseFontSize = document.myForm.bodyChooseFontSize.value;
bodyChooseFontColour = document.myForm.bodyChooseFontColour.value;

etc...

However, the for loop does not work...Firefox JavaScript console reports 'Missing variable name' pointing to the 'e'.

Accessing List Of Divs Via Loop?

Jan 5, 2012

Let's say I have a list of Div's on a page

<div1>
<div2>
<div3>

But depending on the users settings there could be 3 or 30...each div has a button. On press 1 it opens that div(by opens I mean populates with some data. When you press another button on another div, I want it to check the page and close any other div that may be open so you can only have one open at once.I'm familiar with loops and arrays but I'm not quite sure if this is totally possible. I'm not looking for the code, per-se, just a push in the right direction

Jquery :: Loop To Create Dynamic-multiple Vars?

Nov 4, 2010

I am not sure if this is possible, but I want to create a multiple vars dynamically, for instance, these are the vars I create manually,

Code JavaScript:
var left_1 = $('.column-global.left .item-global').eq(0);
var left_2 = $('.column-global.left .item-global').eq(1);
var left_3 = $('.column-global.left .item-global').eq(2);

but the problem is I only need two or one vars above sometimes. but three is the max.

so I am thinking of passing a parameter into the function to tell the code to create either 2 or 3 vars,

Code JavaScript:
// I declare empty vars first
var left_1;
var left_2;

[Code].....

Jquery :: Make List And Apply Click Event In One Loop?

Feb 5, 2010

Code JavaScript:
var listItems = "";
$.each(msg.d, function(index, value) {
listItems += "<li><a href='#' class='" + value.Availability + "' title='" + value.Time + "' >" + value.Time + " - " + value.Availability + "</a></li>"
});
 
var teeTimeLinks = $(listItems + 'li');
$.each(teeTimeLinks, function() {
var link = $(this).find('a');
link.bind('click', function(event) {
event.preventDefault(); //stop the link from going to href
TeeTimeSelected(this);
});
});

The above code works. BUT, msg.d returns 80 objects. We then loop through it and make our list items. AND then we loop through it again and apply the click event. How can this be optimized into one loop?

Jquery :: Populate A List From A PHP Loop That Writes HTML Options From A Db?

Jul 5, 2011

The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.

Code:
//creates the Project dropdown list
while ($proj = mysql_fetch_array($project)){
$id_proj = $proj['projid'];
$name_proj = htmlspecialchars($proj['projectName']);

[Code]....

I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.
