I have an issue on triggering mouse event on a svg.
I am using the library d3.js to handle some graphic tasks. Specifically, when I manually click on a position on the svg, d3 draws a red or blue (depending on the path I am clicking on) circle on it and then returns the d3.mouse coordinates of the click.
Now, suppose I have a set of coordinates and want to trigger programmatically click on the corresponding point on the svg, so that it draws a red or blue circle automatically. How can I achieve that?
I read many solutions here but none allows to click on specific coordinates (while I can easily click on a specific path, for example).
My ideal function would be:
var svgd3 = d3.select('svg#id_svg')
function d3click(x,y,svgd3){
//does the click on [x,y, x,y are relative coord. depending only svg viewBox
...
}
Any idea?
Thanks a lot!

I am using Flot to plot images for our project. For pre-defined shapes like line, pie, I can add tooltip through flot.tooltip.
However, we have some images that are drawn through Html5 canvas API, such as Here. I would like to add a tooltip for the red rectangle and another tooltip for the blank area. Any library to make it work?
With canvas there isn't a good way to detect when the mouse hovers over a particular drawn item; it's just a buffer, with no idea of what operations were used to draw into it. Flot's own hover detection has no concept of what was drawn on the canvas; it just knows that, e.g. the pie starts at a particular point and extend outwards a certain number of pixels.
So no matter what, you will have to write a function that accepts a mouse event, examines whatever data you used to draw the image, and decides what that corresponds to.
Where Flot could help is in providing a way to override the built-in hover function with your own; then the tooltip plugin would simply work with your function. Since you can't currently do that, you have a choice of a) modifying the tooltip plugin to use your function, or b) registering your own mousemove listener on the overlay element, which then generates 'fake' plothover events for the tooltip plugin to consume.
Here is what exactly I am trying to do.
I have an image with square elements inside it. When i click on top left and bottom right corners of those elements they are surrounded with divs with border. I then have functions to drag and resize those divs(once they are created by two clicks). I want to be able to record the resized coordinates of those divs in text boxes. For example if the image is with height=700 and width=500. Then if i create a square div inside it with coordinates top left(x=190,y=150) and bottom right(x=290,y=250). Then if i drag this div around the image i want those coordinates to change accordingly. Same thing to happen if i resize it.
Here i have added the code in a web site. laughter.free.bg/imagemapping/Img1.html What you need to do is click on top left and bottom right corners of one of the snack packs. Then you`ll see a box on the right with the coordinates of this Green bordered div. I want those coordinates to change when i drag or resize this div. You can see the code in the source of the page.
Thanks a lot in advance.
It is possible to bind functions to the resize event through jQuery.
For example, ur kiroid has a class of ui-resizable. You could use something like:
$('.ui-resizable').resize(function() {
// refresh your coords here from $('kiroid').css maby?
})
Problem :
Trying to create a layout looking like this one below where each portion is clickable and has separate entity.
Tried solution and problems with it :
create arc with canvas. Have to add the arc with stroke. Stroke is not clickable. Tried hacks from other answers but they don't seem to work.
Click Event on a Stroke of the Shape(arc) doesn't work
Instead of drawing with arcs, how about this:
use Wedges instead of Arcs
Draw the 3 outside shapes as Wedges and put them on a layer#1.
Draw the 10 inside shapes as Wedges and put them on another layer#2 above layer#1.
Draw the center circle as a Circle and put it on another layer#3 above layer#1 & layer#2.
Attach on.(“click”) to each individual wedge.
Layering will give you the visual "nesting" effect your looking for.
Layering will give you proper click control over each wedge-piece.
I'm making a product site in Adobe Edge. I have a circle div that needs to grow in a span of, let's say, 2 seconds when mouseover. Then a text has to appear in it. When mouseout, the text must disappear and do the reverse animation back to normal size. The circle has also to grow from its center, not the top left corner. I'v been trying to do this for hours with jquery and css3 animations but failed to get a satisfying result.
This is very easy with edge animate.
make your circle element.
set a key frame at 00:00 on the timeline for the circles width and height.
press Q (the transform tool) or select the icon at the top left of the screen just to the right of the arrow.
The transform tool scales things based on the origin point, which is repositionable but is automatically in the center of the selected object.
go to 02:00 on the timeline.
resize your circle.
set a keyframe for your text at 0 opacity.
go forward on the timeline.
set another keyframe for your text at 100% opacity.
group the circle and text into a div.
right click on that div and press 'convert to symbol'.
go back to the stage by clicking 'stage' on the top left of the preview window.
select the object that you want to use to trigger the animation.
open the actions for that object.
paste the following code into a mouseover event: var mySymbolObject = sym.getSymbol("INSERT THE NAME OF YOUR SYMBOL").play();
now make a mouseout event and paste this code: var mySymbolObject = sym.getSymbol("INSERT THE NAME OF YOUR SYMBOL").playReverse();
now what should happen is that onMouseOver, the timeline for that symbol plays forward, and onMouseOut, the timeline for that symbol plays in reverse. This way, if the animation is half way through and they mouse out, it will reverse from where it's at back to the beginning.
Probably you would like also to use mouseenter/mouseleave events rather than mouseover/mouseout, if you will nest text div inside circle div.

I need functionality like Photoshop polygon selection tool in HTML 5. I tried using HTML5 Path properties and I can draw line on canvas but can't have logic to make that line join and make polygon selection.
You can handle clicks on the canvas and put the click coordinates in an array variable.
You can keep adding the points to path array until the path is complete. A path is complete when the user clicks on the first point after create 3 or more points.
You can use this application to draw your polygon and export it to give you the correct HTML and Javascript canvas statements to produce the polygon on a web page
