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).
Is there a way either in PHP or Javascript where the cooridinates of a requested image can be worked out? Let me explain - our members must have an image that is requested from our web server placed above the fold on their web site.
Instead of manually checking that the image is above the fold we would like our application that sends the image (written in PHP) or the Javascript on the members web page that calls the image each time th eweb page loads to tell us where the image will be placed on a web page. Is this possible?
set coordinates for an image I want to add to my page? I have the center coords where I want it to be places x is 400 and y is 90. I've searched all over the internet trying to find a solution.
i have to draw a line between to different coordinates which are going on google maps so for example :
[Code]...
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 just don't know how I could integrate javascript into this. This is my code, not really something functional, the coordinates will pass on to the next page as a variable but limiting the area where the users may click is something that I have not figured out. I can create an area shape but without getting the coordinates from the image. Anything will do, even without <input type=image , if there is some way around this so I can make this work.
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 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)"
looking for the best current way to determine the coordinates of a form's text input that the user just clicked, so that I can use that info to dynamically position a select menu that I will make become visible just below that text input.I am finding all kinds of things.. but most are unclear to me, or worse.what they feel is the proper best current way to go about this
I am trying to get the X and Y coordinates to have a pop up form to use as reference, this is a shopping cart so the more items in the cart the further down the page the form needs to open,
I'm trying to build a simple image-map-creation tool for a web-based app I'm making. (User selects an image, then clicks on it to set image map areas; initially could be just RECTANGLE, later want CIRCLE and POLYGON.)
The quickest "solution" was to display the image with anchor tags, with the ISMAP option on. This causes the x/y coordinates to be displayed in the status bar, at the end of the URL. Sweet, but I'd like to be able to tell when the user clicks, and then grab those values. Then I can build a text string holding their selected area, etc. (It'd be great if I could show the selected area with a box or something, too, but that may require doing it in PHP, building images, etc.) Anyway, does anyone know how I can get the X/Y coordinates when the user clicks? Since it's in a form, can I do something with input types to get the values?
how to find the coodinates for a picture in a middle of the page for example with js? I need this because i have a js script that get the mouse coodinates (X,Y) for the page.I have to modify this script to work only at my picture area and to get me the coordinates for my picture not the coordinates for my hole page. Code:
do ya know an efficient way to get the coordinates of a pictures so that I can use them to create a map? It is a rectangle. Here is the code I set up for a page:
I've got a image zoomer set up using a script located in shiftzoom.js. Basically, the XY coordinates of the mouse are shown in the bottom left of the image as the mouse moves. However, when I am zoomed right out the coordinates are limited to that of the image 'canvas' size (1024,768) and as soon as I zoom in, the coordinates of the mouse (which is in the same place) change until I am fully zoomed in and the coordinates are limited to the original image resolution in the corners. Hope that made sense... This is the relevant code in shiftzoom.js:
When I click on the image the form submitted to the server. As I can see post data contains next additional values: Image1.x=121 and Image1.y=64 These values are coordinates of clicked point relative to image.
Can I get these values in onclick event handler (within the beforeSubmit method)?
I have a grid 500 by 500 with 16 squares each 125 by 125. I can shuffle these images manually by setting the background-position in css. if the position is 0px, -125px how can I store those in an array and pull them in randomly? here is my code:
I have this code for HMTL5 Canvas, however this is a JavaScript directed question not a Canvas question.
<script type="text/javascript"> var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.moveTo(0,400); cxt.lineTo(50,a); cxt.lineTo(100,b); cxt.lineTo(150,390); [Code]...
That will draw a line graph, however I want to get the coordinates from a variable in the URL. So it may be example.com/a=500&b=600 . How would I retrieve these two variables and then insert in to they're respective places?
I have seen examples where it shows the google map and you can draw the polygon, but does anyone know if there is a pre existing script that allows someone to make the polygon and populate a form of the coordinates when they are done?Basically what Im trying to do is have a person draw an area on the google map and then save those coordinates for later use.
