Came across an interesting question put to me by someone today.. Is it possible to list all the co ordinates within a image map rectangle hotspot?
First thought was, yeah sure, then I actually began to think & thought, hmm how would you do that
Does anyone have any ideas? Are there any tricks or math out there that could do such an ask?
In PS you press CTRL+T on new layer. 9 handles appears an then you can stretch/rotate/move that layer. Looking just for that stretch & rotate functionality with dotted/dashed retangle outline. That is, there should be 8 handles on rectangle boundarys and then rectangle should be rotated & stretched via those points. & moved via nineth center point.

image. I can get it to work fine in IE and Opera, but not
Firefox/Netscape.
I've thrown the following small example together to illustrate the
problem - the problem being that FF/NE initially draw my rectangle
before the icon changes immediately to the black no-entry icon. Then,
when I let go of the mouse, the rectangle continues drawing, but it
doesn't stop as the mouseup has already fired of course.
IE was doing the same, but I found the ondragstart/cancelDragDrop
solution to that. I can't find what appears to be a similar solution
for FF/NE.....
Is there a core function that can return the x1,y1,x2,y2 co-ordinates of an element, it seems that this would be a common thing to do.

I want to create a rectangle with a line in the middle with the canvas object. The problem is that the line in the middle gets bigger than the rest of the rectangle. How do I solve this? I believe it has something to do with shadows. If so, how do I turn them off.

I have a php script that gets all images in my directory and outputs them as gallery[0]=firstimage.jpg, [1], [2], .. The php script is supposed to work with the javascript, so to cover all angles here is the php

I am new to Javascript programming, I do know enough to modify certain parts of Javascript coding. I am trying to read a list box line by line and place the item into an image link. I am trying to loop throught the list box and write out the item to the link and also write out the count which is "i" to be the array number, if that make sense. Here is what I have so far. I am not sure what I am missing to get this done.
var i = 0

I have just changed the original HTML and CSS then just barely touched the JavaScript to edit the width, height and the different image urls. As you can see in the sample URL below only 1 image is being loaded and rotated.[URL]
View 1 Replies View RelatedWhat I am trying to do is fairly simple, depending on what option you select in the menu I want the picture to change to different picture. The code that I posted below works perfectly except for one problem. I need the option value to display the color name, and not have the image code in it. I have researched ways to do this without having to use "value" but I just can't find one that works.
function changeimg(){
document.getElementById('colors').src=document.getElementById('color_dropdown_options').value } <label>
<select name="color" class="dropdown_options" id="color_dropdown_options" onchange="changeimg()">
<option value="/images/thumbnails/image1.jpg">White</option>
<option value="/images/thumbnails/image2.jpg">Blue</option>
<option value="/images/thumbnails/image3.jpg">Green</option>
</select></label>
<div id="display"><img src="/images/thumbnails/image1.jpg" width="270" height="382" alt="" id="colors" />

I have created a photography website myself and coded it all in dreamweaver cs4. Now i have created it using html, as i didnt want to limit it to flash users and loading times etc etc. So today i found myself a nice simple slideshow tool that uses html and javascript. i created it using a site online (which i will not post as i dont think we are allowed to post to online sites).
The slideshow loads images up in the background, and it plays them in a random order.
Now i am able to define individual image links to either a url of the an image, or point it to individual images, listing them one by one in my coding, which as a photographer having differet galleries is goign to be a royal pain when i want to have new images showing up.
So my idea is to replace the code that retrieves in dividual images from url's, to replace it with a piece of code that will display an image from a list of about 7 or 8 folders on my server all containing images....
i.e. displays an image from the folder .../images/models/pic01.jpg then it brings up an iamge from a different folder .../images/portrait/pic08.jpg.
Is there a way to do this and how can i go about it?
this is the code i currently have:
<!-- configurable script -->
<script type="text/javascript">
theimage = new Array();
// The dimensions of ALL the images should be the same or some of them may look stretched or reduced in Netscape 4.

I have a site I am working on that I did not build and am having problems with an ajax / javascript call.I was hoping someone with firebug could take a look. I have firebug but I am not a js guy.The big green button that says add to quote list is a link with an image BG. It should swap classes when clicked therefore changing the BG image to a red one as well as the text at the very top right of the screen swapping to add a number to the list of items in the quote list.Sometimes it works... I think only the first time it is clicked, sometimes the text in the top right changes but the image does not etc. If you click it and it does nothing but the refresh the page then the class will change which is weird, it's like it's trying to switch but cant until you reload the page.
View 4 Replies View RelatedI have an unordered list (ul#garment_selector) sitting in a div (div#program_scroller) and each of the list items has a link that I'd like to display an image and some text into a div on the same page. I don't want any fancy animations or anything like that, I just need to display an image and a related description/price into a new div, preferably without reloading. I have quite a few different lists of links and they change all the time so using an array to define the image/text is impractical for my needs.

has several links to click ...all different images. they all link to the same page which is an image gallery. i would like for the new page to open with the related image enlarged in the gallery instead of always showing the first image in the list regardless of which link was clicked. i hope i am being clear.

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.
View 9 Replies View RelatedI 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 trying to make an expand/collapse (essentially accordion) list. So far, everything works and looks fine in Firefox, Safari, and Chrome, but in IE8, the page height is static when it loads, with a page height being as if all headers in the list were expanded. The expand/collapse functionality works,but as you can imagine, there is this big gap of space after the list.
The html markup uses <h2> tags for the always-visible header portion and a <div> for the expanding/collapsing content. The <div> content contains form elements and everything is enclosed in a form tag.Anyways, here is the jQuery code:
$(document).ready(function() {
$('<img src="plus.png" class="icon" />').prependTo('.header');
$('.content').hide();[code].....
i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long

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]......
