I'm using this:
circle.attr({
fill:'#FFFFFF',
'stroke-width':0,
opacity:0,
'pointer-events':'none'
});
The problem is mouse events are still caught and in the DOM inspector that property does not show.
Thanks.
Raphael has a whitelist of attributes it can assign to an element. Since pointer-events: none is not supported in VML then this property is not among the whitelist. To work around this you can do...
circle.node.setAttribute("pointer-events", "none");
Alternatively, if all circles are non-clickable you can include in your CSS stylesheet:
circle {
pointer-events: none;
}
However, none of this will work in any browser that is IE8 or less. If you need old IE support please check out this answer: pointer-events: none VML raphael solution

I'm attempting to move from font icons (icomoon.io) to SVG sprites. Is it possible to use SVG sprites without needing < svg > markup for each icon instance?
What I really liked about the font icons was that I didn't have to clutter my HTML with any additional elements to get the icon to display. I usually just targeted a simple class on whatever element I wanted the icon to display and then used pseudo selectors to display the icon, e.g.:
<h1 class="news">News</h1>
h1.user:before {
font-family: 'icons';
content: '\news';
}
That made a lot of sense to me, and all of my icons were easily managed almost completely in CSS. I rarely had to touch my HTML as long as my markup contained appropriate classes.
I've since switched my build system to Grunt and thought I'd give SVG sprites a try. Almost every1 article2 I3 can4 find5 on the subject says you need to add an additional SVG element to your markup wherever you want each instance to display, e.g.:
<h1>
<svg class="icon">
<use xlink:href="#icon-news">
</svg>
News
</h1>
That seems like a step backwards to me, at least in the management of markup. To me, an icon is usually presentation that should be separate from document structure. Are we doing it this way simply because of the state of SVG support in browsers?
Ideally, I'd love to be able to do something like this:
<h1 class="news">News</h1>
h1.news:before {
display: inline-block;
width: px;
height: px;
background: url(icons.svg#news) no-repeat;
}
This post seems to be closer to what I'm looking for, but I'm not sure of browser support and how to do it automatically in a build system like Grunt.
SVGs can be loaded as files exactly the same way as other images using <img> tags or CSS background, and can be used as sprites exactly the same way too. The only difference is that you have to specify the size you want it (because it's scalable, so the browser doesn't automatically know how big it is like it does with PNGs).
Depending on how you want to use the image, loading them this way may or may not be suitable as some SVG features aren't available, but it can be done.
I have many icons svg, I could use them as fonts if that is helpful and I would like to use ng-click(basically any kinda of click you know) the way that when i click on svg1 and svg2 wont be clicked. Till now i have tried allot of icons and many ways of doing it without success. I have upload to codepen small example, each region of that country have it's own svg which cover other svg's and make click on them impossible. Basic use of svg is below:
<svg>
<use xlink:href="#icon-region"></use>
</svg>
Since all <svg> elements in your page are absolute positioned and have both width and height of 100%, it's possible to only catch elements from the last element. That behavior comes from the way elements are rendered, within layers, like the example bellow:
+-<svg>--+
|+-<svg>--+
||+-<svg>--+
||| |
+|| |
+| |
+--------+
If all those elements have the same width, height and position you can only catch events from the last one, on the top of all.
To avoid this behavior you can do the following, with CSS:
.regionPosition {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
pointer-events: none;
}
.regionPosition > * {
pointer-events: all;
}
This way you disable the event listening from <svg> elements – with regionPosition class – and catch only the events from their immediate children.
Since you're using <use> inside your SVG to get the actually graphics, you can't rely only on Angular to bind the event, because the elements are not yet there when you load the script. You'll need to attach the event listener to the document and then check the target before call the function you want. This can be easily done with jQuery, as follows:
jQuery(document).on('click', '.regionPosition > *', function () {
// Call your function.
});
I changed your code a bit to show how to do it, here: http://codepen.io/anon/pen/waLwrm. I'm using a simple window.console.log() call to just log the clicked element. You can change it to another logic in your final code.

jQuery hover problem due to z-index
I defined CSS transition rules in my svg. It's something like:
#mark #bg {
transition: fill 200ms;
fill: #245575;
}
#mark:hover #bg {
fill: #ff5c26;
}
When I drag it into browser's blank page and test it, the transition works fine. But if I embed the svg into my website using <img src="images/mark.svg" alt="">, the transition doesn't work.
Did I miss something?
Images either via <img> tags of via the CSS background-image image property cannot be interactive and have other restrictions in order to maintain user's privacy and security.
If you ask yourself "could I do this if the image was a .png or a .gif?" then you'll be on the right lines. Browsers have deliberately chosen to keep to the same mental model for SVG files so that the capability of images is easy to understand.
If you want transitions to work you'll need to use an <object> or <iframe> tag or embed the SVG inline in the html document.
Are there situations where an SVG <text> element's dominant-baseline style will be ignored?
I have two <text> labels in two different parts of my SVG. The dominant-baseline: central applied to one works without issue (for example, when I open it up in Chrome's web inspector and change the value, the element moves around as I would expect it to), but it does not seem to affect the other (ex, changing the style's value from the web inspector doesn't change the position of the element).
Is there any reason this could be?
Here is a screenshot of the relevant code:
(I'll post a fiddle demonstrating the problem if I can figure out how to reproduce it)
The culprit was an errant display: inline that the .label was inheriting from its HTML counterpart.
The fix:
svg.label {
display: block;
}
I am using a drop shadow filter inside an SVG file that is embedded using an img tag. On my MacBook, it looks fine in Safari. However, in mobile Safari, the graphic gets really pixelated and loses all it's sharpness. When the filter is not applied, the SVG renders fine. Is there any way to fix that besides to pass on the filter?
This problem is still relevant in 2018, and I've found a solution. You can duplicate the element you give the filter to, place it below the actual element, and keep filter only on it, without any filter on the element. This way, Safari and other browsers will only rasterise the element with the shadow when resizing, however it will be hidden by the sharp-looking vector element. You can see examples and read more here.
Unfortunately I tried all the suggested workarounds for this, none of them worked, the only thing that worked for me was putting the svg inline, not as an img tag.
Surprised this issue appears to have been around for so long!
You should try explicitly setting the "filterRes" attribute of the filter to a value that matches retina displays.
It's 2021 and it's still relevant. I found a workaround that worked for me: You can enlarge the svg and then use a css-transform to scale it back:
.section_logo img {
height: 500%;
transform-origin: top left;
transform: scale(0.2);
}
