通过经典<a>链接更改svg中<image>的xlink：href

Question

I have a svg in my webpage (I use php):

<svg width="500px" height="500px" xml:lang="fr"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<image width="500" height="500" xlink:href="img1.jpg" opacity="0.35" />
</svg>

I would like to be able to change the xlink:href variable when clicking on a link (and without reload the webpage), something like:

<a href=#" onclick="changexlinkhref(img2.jpg)">change with img2</a>

But I don't know what would be the code of the js function changexlinkhref(img){} (and for now I don't use jquery on my project)

Thanks!

Answer 1

You'll need to put the img2.jpg argument in single quotes Then something like this should do it provided you only have one image element on the page.

function changexlinkhref(value) {
  document.querySelector("image").setAttributeNS('http://www.w3.org/1999/xlink', 'xlink:href', value);
}
