Dropdown Lists With Specific Options

Feb 18, 2010

I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list.Anyway, let me show you what I really want to do. Please see the code below. If you want to properly run this, please make six dummy images and name them as followed: silo_1_ empty.jpg, silo_2_empty.jpg, silo_3_empty.jpg, tm1.jpg, tm2.jpg, tm3.jpg.What I want to do next is to apply a restriction to the dropdown lists. For instance, if TM#1 is selected, only Silo1 can be selected from the LOCATIONS, and Silo2 and 3 will be removed from the option. If TM#2 is selected, Silo 2 and 3 can be selected and Silo 1 will be removed. TM#3 can be in all locations.

In total, there are 12 modules and 20 locations. Each module image can only appear in one location at a time, but the options to select a location are restricted.

Dropdown Lists With Specific Options?

Feb 18, 2010

I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list. For instance,

<select name="module">
<option value="pic1.jpg>TM1</option>
<option value="pic2.jpg>TM2</option>
<option value="pic3.jpg>TM3</option>

[Code].....

Note: The option values are just examples, but each option must have a value in order for other things to work.

Here is what I need to do:

If TM1 is selected, only Box1 and Box 2 are available (Box3 is removed from the dropdown "location" list);

If TM2 is selected, only Box 2 is available (Box 1 and 3 are removed from the dropdown "location" list);

If TM3 is selected, all options in the dropdown "location" list are available.

Creating/adding Options To Select Lists?

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

JQuery :: SlideToggle Dropdown Menu WITHOUT Nested Lists?

Oct 13, 2011

So my problem is that I've got a main navigation with a dropdown menu underneath "products". I positioned the dropdown menu, set it to display: none, then wrote jQuery to slideToggle the menu when a particular LI is hovered over. The issue is that when I hover over the "Products" LI and try to hover over the dropdown, it disappears because I'm no longer hovering over that LI.

You're probably thinking "Just make nested lists!!!!". Well, I don't want to. I've got some jQuery being applied to the main navigation that I don't want to effect the dropdown. I just want a way to be sure the dropdown is open when the mouse is hovered over either the main LI or the dropdown UL and that the dropdown is closed when the mouse is hovered over neither.

In my code I've tried to make it so that if the mouse is over the dropdown UL it stays open, but the mouse leaving the LI trumps that maybe? HELP PLEASE! My HTML and jQuery is below.

Dependable Dropdown Lists (4 Level) With Multiple Selection

Nov 27, 2011

Dependable dropdown lists (4 level)
1 Level dropdown list
2 Level dropdown list
3 Level dropdown list
4 Level dropdown list
Every dropdown list is depends on another dropdown list

For example if I select a value from 1 dropdown list then 2 dropdown list will appear. And then I select a value from 2 dropdown list then 3 dropdown list will appear. And if I select a value from 3 dropdown list then 4 dropdown list. Multiple selection will be enable. It means every dropdown list may have hundreds of values. Thus, In this situation of multiple selection of values I analyze that, use of dropdown isn't suitable because if a dropdown value has 500 related values then these 500 values disturb the page design.

Selecting All Options In A Dropdown

Jul 23, 2005

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;

for(var i=0; i<length; i++)
{
element.options[i].selected=true;
}
}

Evaluate Options In Dropdown For Unique Selection?

Jul 23, 2005

I don't know how to evaluate the no-blank selections against each other from a form as follows: .

I have a form with 6 dropdown fields, each containing a selection of 30 options (the 30 options are the same for each dropdown list). The user needs to select 'one of the 30 options' from each dropdown selection, but each option they select must be unique (no duplicate selections) or it must be left blank. E.g. The user can select Option3 within "dropdown1", but must select a different option for the other dropdowns - OR leave them unselected.

Dropdown Menu Options - Year / Month And Day

Apr 9, 2009

I've come across this archive at [URL]. What I would like is to have it to have it include "days" as well. So lets say as of today (Apr 8th), when a user choose Apr, the dropdown for 'day' will have the options 01, 02, 03.....08. Another thing to note is that each month has different number of days in it. I've tried playing around for quite some time now...but so far no luck.

AJAX :: Populate The Options Of 5 Dropdown Boxes?

Jan 16, 2011

I have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.

I want to speed it up as follows:

1) User selects one of 50 products from a dropdown list.

2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)

3) User can freely input the remaining 5 dropdowns without the page reloading.

JQuery :: Select Dropdown With Many Options, Most Efficient Way To Populate?

Jun 16, 2010

I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?

Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...

Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?

I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?

Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..

Check Allowed Dropdown Combination And Filter Options?

how to find which combinations are acceptable based on what has already been selected.

Dropbox - Enable Certain Entries In Second Dropbox When Specific Options In First Dropbox Are Selected

Aug 9, 2010

I created a dropbox that would only enable certain entries in a second dropbox when specific options in the first dropbox are selected.

For example, if A is selected in dropbox 1, then Z and X will be available for selection in dropbox 2, whereas if B is selected in dropbox 1, then xyz and zyx will be available for selection in dropbox 2.

Everything was going fine until I got past my 3rd entry, in which case no matter what I put in dropbox 1 (except for the first 3 entries), nothing appears in dropbox 2. There appears to be no problem in the code either...

JQuery :: Select A Specific Class Inside A Specific Div Based On The ID From A Button Elsewhere On The Page

Mar 10, 2010

<div class="box top"></div>
<div class="box main">
<div class="box header">
<div class="badge"><ul><li class="active"><span>60</span></li></ul></div>

[Code]....

What is happening is $(this) is no longer based on .expand being the (this) that is clicked.

like if i have a button SOMEWHERE randomly on the page with this

<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.

Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??

just like the .expand click function I posted on the top of the post that works?

Browser Detect To Load Specific Code For Specific Browsers?

Oct 6, 2009

Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.

I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.

Is there a single method using JS that works for all browsers?
