I want to create links to jump across an SVG. So I placed some ID's on the objects in the SVG I want to jump to and added some A tag elements linking to those ID's. This works when the SVG is inline, but when I use the Object tag to load the SVG it doesn't work. This makes sense because the object tag loads the SVG as a separate document in the main document.
Some code describing the scenario:
[some-html]
<object type="image/svg+xml" data="/somesvg.svg"></object>
[more-html]
Jump to #id-somewhere-in-the-svg
And some in the SVG:
<a id="id-somewhere-in-the-svg" xlink:href="...">
<g id="some-id">
<path d=...
For now, I solved the problem using Javascript, but I would like to know if there's a pure HTML solution.
In our project we are calling all the icons like this:
<svg focusable="false" aria-hidden="true" class="icon icon--extra-small ">
<use xlink:href="#icon-search" href="#icon-search"></use>
</svg>
Right now we are loading all the icons in a hidden div at the footer of the document.
Is there a way to use an external source for the svg without having to rewrite all the icons?
I assume JavaScript is acceptable for your project. Here is an option that you could choose to do.
Create another file called svg-icons.js or anything really.
Add <script type="text/javascript" src="svg-icons.js"></script> below the closing </body> tag.
In that file, add something along the lines of:
document.querySelector('.my-icon').innerHTML = '<svg focusable="false" aria-hidden="true" class="icon icon--extra-small "><use xlink:href="#icon-search" href="#icon-search"></use></svg>';
Then whenever you want to use that icon in your html, add a div or span (according to your needs) with the same class:
<div class="my-icon"></div>
The component is fairly small, so I don't suggest doing this. Additionally, if you are using JQuery, you could look into $.load(). That will help a lot when starting to use the same components across the entire website.
I'm trying to show an SVG, which, when clicked, links to another page. Here is what I tried:
<a href="foo.html">
<embed src="something.svg" />
</a>
What is the preferred method for doing this?
Don't use the embed tag. Instead use an <img> tag and the anchor should work just fine.
How to make them in HTML or CSS?
For example:
http://draw.to/D11KGJr
I've heard about the map tag, but it seems it only generates an invisible clickable area, on which you can't apply CSS properties, like border or background.
If you are talking about that drawing: it's a canvas element.
See here for a tutorial: https://developer.mozilla.org/en-US/docs/Canvas_tutorial
Besides using CSS 3 techniques as the others proposed, you could also embed SVG in your HTML document.

This is possible - within limits, and only on newer browsers - using CSS3 techniques. For an example, see this CSS3 Twitter Fail Whale.
That uses the canvas element.

There are other approaches for non-rectangular elements, which may be more appropriate for what you actually need, if you can say more about your specific requirements.
I have tried to change the images on my site from img to svg, changing img tags to embed and object tags. But, implementing the onclick function, which previously was contained in the img tag, is proving most difficult.
I found onclick had no effect when placed inside the object or embed tag.
So, I made a div exclusively for the svg, and placed onclick in this div tag. But, no effect unless visitor clicks on the edges/padding of the image.
I have read about overlaying a div, but am trying to avoid using absolute positioning, or specifying position at all.
Is there another way to apply onclick to a svg?
Has anyone encountered this problem? Questions and suggestions are welcome.
You can have an onclick event in the svg itself, I do this all the time in my work. make a rect over the space of your svg, (so define it last, remember svg uses the painters model)
rect.btn {
stroke:#fff;
fill:#fff;
fill-opacity:0;
stroke-opacity:0;
}
then as an attribute to the rect add the onclick (this can be done with js or jquery as well).
<div>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
<g>
<circle ... //your img svg
<rect class="btn" x="0" y="0" width="10" height="10" onclick="alert('click!')" />
</g>
</svg>
</div>
this will work in almost all browsers: http://caniuse.com/svg
If you just use inline svg there is no problem.
<svg id="svg1" xmlns="http://www.w3.org/2000/svg" style="width: 3.5in; height: 1in">
<circle id="circle1" r="30" cx="34" cy="34" onclick="circle1.style.fill='yellow';"
style="fill: red; stroke: blue; stroke-width: 2"/>
</svg>
This started as a comment on RGB's solution but I could not fit it in so have converted it to an answer. The inspiration for which is entirely RGB's.
RGB's solution worked for me. However, I wished to note a couple of points which may help others arriving at this post (like me) who are not that familiar which SVG and who may very well have generated their SVG file from a graphics package (as I had).
So to apply RGB's solutions I used:
The CSS
<style>
rect.btn {
stroke:#fff;
fill:#fff;
fill-opacity:0;
stroke-opacity:0;
}
</style>
The jquery script
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$(".btn").bind("click", function(event){alert("clicked svg")});
});
</script>
The HTML to code the inclusion of your pre-existing SVG file in the group tag inside the SVG code.
<div>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
<g>
<image x="0" y="0" width="10" height="10"
xlink:href="../_public/_icons/booked.svg" width="10px"/>
<rect class="btn" x="0" y="0" width="10" height="10"/>
</g>
</svg>
</div>
However, in my case I have several SVG icons which I wish to be clickable and incorporating each of these into the SVG tag was starting to become cumbersome.
So as an alternative approach where I could employ Classes I used jquery.svg. This is probably a shameful application of this plugin which can do all sorts of stuff with SVG's. But it worked using the following code:
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$(".svgload").bind("click", function(event){alert("clicked svg")});
for (var i=0; i < 99; i++) {
$(".svgload:eq(" + i + ")").svg({
onLoad: function(){
var svg = $(".svgload:eq(" + i + ")").svg('get');
svg.load("../_public/_icons/booked.svg", {addTo: true, changeSize: false});
},
settings: {}}
);
}
});
</script>
where HTML
<div class="svgload" style="width: 10px; height: 10px;"></div>
The advantage to my thinking is that I can use the appropriate class where ever the icons are needed and avoid quite a lot of code in the body of the HTML which aids readability. And I only need to incorporate the pre-existing SVG file once.
Edit: Here is a neater version of the script courtesy of Keith Wood: using .svg's load URL setting.
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$('.svgload').on('click', function() {
alert('clicked svg new');
}).svg({loadURL: '../_public/_icons/booked.svg'});
});
</script>
I got this working accross the latest versions of Firefox, Chrome, Safari and Opera.
It relies on a transparent div before the object that has absolute position and set width and height so it covers the object tag below.
Here it is, I've been a bit lazy and used inline styes:
<div id="toolbar" style="width: 600px; height: 100px; position: absolute; z-index: 1;"></div>
<object data="interface.svg" width="600" height="100" type="image/svg+xml">
</object>
I used the following JavaScript to hook up an event to it:
<script type="text/javascript">
var toolbar = document.getElementById("toolbar");
toolbar.onclick = function (e) {
alert("Hello");
};
</script>
In case you're fine with wrapping the svg in another element (a for example) and putting onclick on the wrapper, svg {pointer-events: none;} CSS will do the trick.
It worked by simply replacing the <embed/> tag with <img/> and deleting the type attribute.
For instance, in my code, instead of:
<embed src=\"./images/info_09c.svg\" type=\"image/svg+xml\" width=\"45\" onClick='afiseaza_indicatie($i, \"$indicatii[$i]\")'>
which does not answer the clicking, I wrote:
<img src=\"./images/info_09c.svg\" height=\"25\" width=\"25\" onClick='afiseaza_indicatie($i, \"$indicatii[$i]\")'>
It works in Internet Explorer and Google Chrome, and I hope that in the other browsers too.
You could use following code:
<style>
.svgwrapper {
position: relative;
}
.svgwrapper {
position: absolute;
z-index: -1;
}
</style>
<div class="svgwrapper" onClick="function();">
<object src="blah" />
</div>
b3ng0 wrote similar code but it does not work. z-index of parent must be auto.
When embedding same-origin SVGs using <object>, you can access the internal contents using objectElement.contentDocument.rootElement. From there, you can easily attach event handlers (e.g. via onclick, addEventListener(), etc.)
For example:
var object = /* get DOM node for <object> */;
var svg = object.contentDocument.rootElement;
svg.addEventListener('click', function() {
console.log('hooray!');
});
Note that this is not possible for cross-origin <object> elements unless you also control the <object> origin server and can set CORS headers there. For cross-origin cases without CORS headers, access to contentDocument is blocked.
Have you looked into using the CSS z-index property to make the container dev be "on top" of the svg? Because the div is (presumably) transparent, you will still see the image exactly as before.
This, I believe, is the best-practice, non-hack, intended way of solving your problem. z-index is only useful for elements that have a position property of fixed, relative, or, as you've heard, absolute. However, you don't actually have to move the object.
For example:
<style>
.svgwrapper {
position: relative;
z-index: 1;
}
</style>
<div class="svgwrapper" onClick="function();">
<object src="blah" />
</div>
For what it's worth, it would also be a little more elegant and safe to not use onClick at all, but instead to bind the click event using javascript. That's another issue altogether, though.
Assuming you don't need cross browser support (which is impossible without a plugin for IE), have you tried using svg as a background image?
Experimental stuff for sure, but thought I would mention it.
Perhaps what you're looking for is the SVG element's pointer-events property, which you can read about at the SVG w3C working group docs.
You can use CSS to set what happens to the SVG element when it is clicked, etc.
Click on SVG's <g> element in <object> with click event. Works 100%. Take a look on the nested javascript in <svg>. Don't forget to insert window.parent.location.href= if you want to redirect the parent page.

I wrapped the 'svg' tag in 'a' tag and put the onClick event in the 'a' tag
I had a similar issue: it only seems that the onclick event is not occurring, but it is firing twice
the svg tag had an onclick option, like: <svg ... onclick="someJsFunction() ...> it opens a dropdown menu, and had a class option named f.e. class-for-svg
the path (included in the svg tag) had no any class option,
in the other hand, I had a window.onclick function to close the dropdown when the user clicks on the somthing else, here the dropdown was clossing - when the object's class option matched to the svg's class option
so when I clicked on the path portion inside the svg tag - the window.onclick event accurred too, and because of the does not matching(to the class name), the dropdown was clossed imediatelly, and it seems that the onclick event is not happening )
in reality it happens twise, one opens, an the second closses the drop down
solution: add the same class option to the path tag too )
enjoy please )
