The Quantity up and down arrows svg, which use the following code:
<button class="button button--icon" data-action="dec">
<span class="is-srOnly">Decrease Quantity:</span>
<i class="icon" aria-hidden="true">
<svg>
<use xlink:href="#icon-keyboard-arrow-down"/>
</svg>
<button class="button button--icon" data-action="inc">
<span class="is-srOnly">Increase Quantity:</span>
<i class="icon" aria-hidden="true">
<svg>
<use xlink:href="#icon-keyboard-arrow-up"/>
</svg>
</i>
</button>
only show up on select products on our website (Buttons still work). I haven't been able to figure out if there is a pattern or a method to why they are showing up or not showing up, but some of them look like this:
and others look like this:
If more info is needed, please let me know, but this is all I could find that was relevant, but I could be mistaken.
The arrows are generated by JavaScript. If they are showing on some pages and not on others, that would lead me to believe there is a JavaScript error on the page where they are not loading. Open your Chrome DevTools console to check for any JavaScript errors, and try to resolve them. Without a link to the site, I cannot say specifically what the error is that is breaking this.
I want to create some links and hover effects inside a svg image. So, I created some custom transparent areas inside one svg image, in an online images editor, in order to do that. But when I try to apply some links in those custom areas, as show below, it does not work. How can I make it work?
<body>
<svg>
<defs></defs>
<!-- custom ellipse which the link does not work -->
<a href="some-link.com">
<ellipse />
</a>
<!-- normal path from the svg image, which the link work -->
<a href="some-link.com">
<path></path>
</a>
<!--rest of the image with many paths-->
<path></path>
</svg>
</body>
The ellipse element seems to be invalid. And since the markup has an error, it might affect even the functionality of the parent element.
The self-closing tag should have the slash at the end (since SVG is based on more strict XML) like below:
<ellipse />
Does this change solve the problem with the link?
I'm aware that there are plenty of methods to use SVG sprites in HTML. My preference to this date has been to use something like
<div class="container">
<svg class="icon">
<title>Icon Title</title>
<use xlink:href="/svg/sprite.svg#icon"/>
</svg>
</div>
However, now I wanted to load the sprite from a subdomain, like this:
<div class="container">
<svg class="icon">
<title>Icon Title</title>
<use xlink:href="https://sub.domain.com/svg/sprite-home.svg#icon"/>
</svg>
</div>
Unfortunately, this doesn't work as the file is not fetched. I've tried with <object> as well, but that doesn't seem to work either.
So far, I'm only able to use
<?php include_once("https://sub.domain.com/svg/sprite.svg"); ?>
It's ok as a quick fix, as this doesn't involve much refactoring. However, this also means the HTML gets bloated.
With the <use> method the sprite gets cached. But with the include method the sprite isn't cached, only gets embedded, and so it is far from ideal.
Does anybody use any alternative to the php include method that is compatible with cross domain requests and browser caching?
Thanks to this post at css-tricks I've been able to work out how to do this. The idea is to AJAX to bring the SVG sprite with jQuery like this (see post for vanilla version):
$j.get("https://sub.domain.com/svg/sprite-home.svg", function(data) {
var div = document.createElement("div");
div.className = 'no-display';
div.innerHTML = new XMLSerializer().serializeToString(data.documentElement);
document.body.insertBefore(div, document.body.childNodes[0]);
});
What this does is insert the SVG at the beginning of the document. Unlike the original post, I've added a class to make it hidden, as otherwise you get a blank big space at the top in Chrome. The result is great (it works with local files too) and now you can reference icons by just their id.
<div class="container">
<svg class="icon">
<title>Icon Title</title>
<use xlink:href="#icon"/>
</svg>
</div>
There are many advantages to this technique:
SVG sprite is cached
Really simple to use as you only reference the icon
You can request several SVG sprites and they all work the same
The only thing to bear in mind is that, this requires CORS AJAX to be set up. For those using nginx, it would be simple enough:
location ~* \.svg$ {
...
add_header 'Access-Control-Allow-Methods' 'GET';
add_header 'Access-Control-Allow-Origin' 'https://your.domain.com';
}
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 )
