Compare Items In A Drop Down List
Jul 29, 2010
I want to compare items based on what the user picks there will be 3 drop down menus and the drop down menus should alter the HTML table each time it is changed, giving different option values and stuff. I am wondering how to go about this I have the basic stuff setup but I am not really sure how to add to a table that all 3 options use.Here is my current code for the drop downs.
<form name="compare">
<select name="compare">
<option value="V1">Value 1</option>
[code]...
I want the user to select one of the options from above and a table to show up showing the differences between the others for example; someone selects Value 1 for compare, and Value 2 for compare 2, and Value 3 for Compare 3, they should be shown a table which has the differences between Value 1, Value 2, Value 3. So lets say Value 1 and Value 3 offers you "Help" while value 2 doesn't. it should show a table that says
Features Value 1 Value 2 Value 3
Help YES NO YES

I have a dynamic table where I would like to update cells by using a drop list selecting from half a dozen items. I have searched W3Schools for a tutorial but I am obviously looking in the wrong place. The working code I have thus far is:-
function insRow()
{
var x=document.getElementById('myTable').insertRow(1);
var a=x.insertCell(0);
var b=x.insertCell(1);
var c=x.insertCell(2);
var d=x.insertCell(3);
var e=x.insertCell(4);
var f=x.insertCell(5);

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 have an array like this:
I need to compare these array items to my site div id's and make an onblur functionality that changes the input field value.
It does not change the selected input field value(this.value). And it only alerts when blurring from the input field that is first in the array(id1). If i click to the input field id="id2" it does not alarm?

What I am trying to do is build a script that will read through an array of words and compare another word to the list to find where it would be placed alphabetically; between which two words would my word go.
Here is what I have come up with so far which doesn't work with words shorter than the shortest word in my list, or words spelled like the shortest word in my list except having a few more characters, plus more various issues.
Example: My list
If I use keywords "apex," or "as", this script fails.
What can I do to fix my code...

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 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 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 have a javascript index that is similar to the one in the Windows
help. It has a text field that allows the you to type text and it
finds the closest item in the list below the text field. The list is
simply a select element with options that looks like this:
<SELECT>
<OPTION VALUE="1">A
<OPTION VALUE="2">B
<OPTION VALUE="3">C
</SELECT>
My problem is when I have a large list, the closest entry selects the
item in the list at the bottom of the list box, not the top of the
list box.
So here's the question: Is there a way to get the list box to display
the selected item and move it to the top of the list and not just find
it at the bottom?
To get an idea of what I 'want' it to look like, in Windows, go to
Help & Support (in XP it's in your start menu) and pick Index. I
basically want it to mirror that functionality.

I am working on a site with a left menu that slides out, and I've converted it to the top to drop down. So far, it is working ok, but the submenu items need to be below the parent, preferably left aligned. I have played with it a bit and so far can't seem to achieve what I want. See below where I'm clicking Resources and the menu is way too high and over to the right.

I'm trying to get drag and drop script working from this tutorial: [URL]. I want to drag items between columns (DIV's).
Here is my code:
document.onmousemove = mouseMove;
document.onmouseup = mouseUp;
document.onmousedown = mouseDown;
window.onload = function(){
// Create our helper object that will show the item while dragging
dragHelper = document.createElement('DIV');
dragHelper.style.cssText = 'position:absolute;display:none;';
CreateDragContainer(
document.getElementById('DragContainer1'),
document.getElementById('DragContainer2'),
document.getElementById('DragContainer3')
);
document.body.appendChild(dragHelper);
} .....
Every top level item in these containers should be draggable. Do this by setting the DragObj attribute on each item and then later checking this attribute in the mouseMove function
for(var j=0; j<cObj.childNodes.length; j++){
// Firefox puts in lots of #text nodes...skip these
if(cObj.childNodes[j].nodeName=='#text') continue;
cObj.childNodes[j].setAttribute('DragObj', cDrag);
}}}
This script is working only particularly: [URL]

I have created a simple portfolio item for a site I am working on, with left and right buttons to move between the visible thumbnails in the portfolio.
The problem is this: when I click on one of the left or right buttons used to scroll the active list items, it resizes the space between all of the thumbnails by 1 pixel per click, up to 10 clicks.
Here is the markup and my javascript:

Then I have a string of id's that I want to set to selected like so.

Is it possible to use jquery (preferably in a one liner) to set first, third and fifth to selected.?
