Working With Image Coordinates And Dynamic Linking.
Jul 23, 2005
I have a page with a large centre-aligned image on it. I want a
functionality whereby users can click their mouse on any point in this
image and it would then show a virtual mouse pointer at the place where
they clicked it. If they were to click somewhere else, the position of
the virtual cursor would change.
The position of the cursor needs to dynamically generate a link and
display it in a form field text edit box.
If that link is then viewed separately, it would launch the same page
with the virtual mouse pointer at the location where the original
person placed it.
Basically I want to be able to have one guy point to a location on the
image for the benefit of another guy, but graphically as opposed to
relying on written explanation.
I have a simple problem: mark a list of defects on an image.
I think the best way to do it is to select a single deffect, then take two coordinates of coursor form an image on a web page (first when user press the button, and the second when he releases it). Those two points are going to be send to the web application (i.e. with AJAX) and saved in a database. Later, I will use those points to render the image with RMagic (drawing the lines and defects list numbers on top of the image).
i have to draw a line between to different coordinates which are going on google maps so for example :
the above coordinates are in xml format which, i later call in Java script functions and display them on the map as a simple pointers what i need is from one point of coordinates to another point of coordinates Java script would draw a line which would represent the direction from one coordinate to other .
point.x and point.y values get submitted to the server specifying where on the image I have clicked.
Is there any (simple) way to get ahold of that point.x and point.y BEFORE they are sent to the server (and prevent that from happening)? Ie. I just want the points where someone clicks on an image and not interested in a submission to the server.
i have a circular image... with pie shaped areas. i would like to use some form of jQuery and either a popup or tool tip that is CSS customizable... i looked at maphilight in the jquery plugins, but i dont see how you can make a pop up with that. unless there is another method i should go about doing this..
I need to restrict an area on the image but also get the coordinates from the image. I am using a form element "input type=image" so I can get the X Y coordinates from an image. I don't want the user clicking on a whole image, in this case a map of a country. I don't want the users clicking off the country's borders in to another country and I want to be able to get the coordinates from inside the country. I have tried to mix the element from the form with the area shape so when someone will click on the image it will first verify if it's over the hotspot and if it's over the poly coords then it will allow the user to click, the form will submit and the coordinates will be stored into the database.
I am trying to capture the image coordinates when a user clicks on an image. My code is working in Firefox, Mozilla, Netscape, IE, and Opera, but fails under Konqueror (and I suspect Safari). The code below fails in Konqueror when the page is scrolled down; the coordinates are off by the scroll amount.
My code in the html img tag: onClick="MLDot(event)"
Here is the section I am currently looking at.
Below is a very simple jquery slideshow script which functions exactly as it should. But, if I link an image in the DIV set (See proposed change section) the slideshow breaks, instead of cycling through each image in turn it keeps trying to cycle the first image over and over. Script linking in header of HTML page:
// uncomment the 3 lines below to pull the images in random order // var $sibs = $active.siblings(); // var rndNum = Math.floor(Math.random() * $sibs.length ); // var $next = $( $sibs[ rndNum ] );
I have put together an image gallery that contains links to each individual image, however, I would like to link to individual images on a separate html document and cannot for the life of me determine how to go about doing this. rnmix
I'm working on a gallery site using galleriffic. It is composed of 13 seperate galleries (couldn't figure out a way to integrate them into one) and what I would like is an index page which users can jump to any specific image in a gallery. [URL]. There is a current example, and what I'm trying to do is make a drop down menu form where someone could select a piece of granite, (eg. Giallo Latina) and it would jump them straight to that page. However if I link to "butterscotch.html#5" it doesn't work. Is there any way of creating a drop down menu that could handle this?
This is what I am seeking: On the main page we have 3 different images (img1, img2, img3), that must link to another page (photo page) with a photo in the middle enlarged: for example if I click img1 i will go to the photo page with img1 enlarged in the middle, and if I click img2 will go to the photo page with img2 in the middle. the photo page has photo thumbnail sliding at the bottom of the page that links to the same middle enlarged photo based on the clicked photo. is it doable with JS? or should I look somewhere else?
I'm frustrated :(. I've been trying to get this single piece of code to work. I've looked at quite a few sources out there, but everything I try fails. My site uses AJAX to upload a file, and once complete I dynamically add the file name, size, description, etc to a table.
If the user types "a" then the select box is populated with "Choose An Animal...", then the three three animals beginning with A. So far so good. But if the user selects say Albatross and then types the letter b then the option "Bear" is selected rather than "Choose An Animal". Although the code is sel.selectedIndex = 0; (not 1). How can I force the selected index to 0 when a choice has been made previously? Is this a bug - if so it is the same in IE and FF.
In Opera, the dynamic resize of the iframe isn't working correctly. As you can see in the code, I have set a minimum height of 200px so the iFrame should always be a minimum height but if the content requires it will increase. It works fine in IE8, Safari, FF, Chrome but not in Opera. In Opera it just sets the height at 200px.
When i try to dynamically change the height of an iframe in ie through a java-script to match its content (a html page containing a flash movie, it doesn't resize the iframe at first, but when i reload the same page into the iFrame it resizes as planned, how come?This script works well in firefox, safari and netscape, but i cant get it to work in ie(8, 7). And i get the same problems with every resizing script i've tried. This is the script i use:
I've built in an iFrame that pulls in various other pages of variable height. Can you make this iFrame render its size based on it's src content ? I've been trying to use the scrollHeight of the frame but it isn't working. My current code:
Basically my code always renders the scrollHeight at 150 but the test.html I'm pulling into the frame I've made a height of 500px ?
