I'm messing around with SVG and I was hoping I could create SVG files in Illustrator and access elements with Javascript.
Here's the SVG file Illustrator kicks out (It also seems to add a load of junk to the beginning of the file that I've removed)
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="276.843px" height="233.242px" viewBox="0 0 276.843 233.242" enable-background="new 0 0 276.843 233.242" xml:space="preserve"> <path id="delta" fill="#231F20" d="M34.074,86.094L0,185.354l44.444,38.519l80.741-0.74l29.63-25.186l-26.667-37.037 c0,0-34.815-5.926-37.778-6.667s-13.333-28.889-13.333-28.889l7.407-18.519l31.111-2.963l5.926-21.481l-12.593-38.519l-43.704-5.185 L34.074,86.094z"/> <path id="cargo" fill="#DFB800" d="M68.148,32.761l43.704,4.445l14.815,42.963l-7.407,26.667l-33.333,2.963l-4.444,14.074 l54.074-1.481l22.222,36.296l25.926-3.704l25.926-54.074c0,0-19.259-47.408-21.481-47.408s-31.852-0.741-31.852-0.741 l-19.259-39.259L92.593,8.316L68.148,32.761z"/> <polygon id="beta" fill="#35FF1F" points="86.722,128.316 134.593,124.613 158.296,163.872 190.889,155.724 214.593,100.909 194.593,52.02 227.186,49.057 246.444,92.02 238.297,140.909 216.074,172.761 197.556,188.316 179.778,169.798 164.963,174.983 163.481,197.946 156.815,197.946 134.593,159.428 94.593,151.279 "/> <path class="monkey" id="alpha" fill="#FD00FF" d="M96.315,4.354l42.963,5.185l18.519,42.222l71.852-8.148l20.74,46.667l-5.926,52.593 l-24.444,34.074l-25.185,15.555l-14.074-19.259l-8.889,2.964l-1.481,22.222l-14.074,2.963l-25.186,22.963l-74.074,4.444 l101.481,4.444c0,0,96.297-17.777,109.63-71.852S282.24,53.983,250.389,20.65S96.315,4.354,96.315,4.354z"/> </svg> As you can probably see, each element has an ID, and I was hoping to be able to access individual elements with Javascript so I could change the Fill attribute and respond to events such as click.
The HTML is bog basic
<!DOCTYPE html> <html> <head> <title>SVG Illustrator Test</title> </head> <body> <object data="alpha.svg" type="image/svg+xml" id="alphasvg" width="100%" height="100%"></object> </body> </html> I guess this is two questions really.
Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG.
If it is possible, what's the technique?
UPDATE
At the moment, I've resorted to using Illustrator to create the SVG file, and I'm using Raphaël JS to create paths and simply copying the point data from the SVG file and pasting it into path() function. Creating complex paths such as might be needed for a map, by coding the point data manually is (to my knowledge) prohibitively complex.

SVG images can be written directly into the HTML document using the <svg> </svg> tag. To do this, open the SVG image in VS code or your preferred IDE, copy the code, and paste it inside the <body> element in your HTML document.
The z-index only works on the complete content. This is because the HTML rendered controls the positioning before handing off to the SVG rendered to place the internal SVG contents. So, basically there is no z-index for SVG, it uses the painters model.

Definitely.

This annotated code snippet works:
<!DOCTYPE html> <html> <head> <title>SVG Illustrator Test</title> </head> <body> <object data="alpha.svg" type="image/svg+xml" id="alphasvg" width="100%" height="100%"></object> <script> var a = document.getElementById("alphasvg"); // It's important to add an load event listener to the object, // as it will load the svg doc asynchronously a.addEventListener("load",function(){ // get the inner DOM of alpha.svg var svgDoc = a.contentDocument; // get the inner element by id var delta = svgDoc.getElementById("delta"); // add behaviour delta.addEventListener("mousedown",function(){ alert('hello world!') }, false); }, false); </script> </body> </html> Note that a limitation of this technique is that it is restricted by the same-origin policy, so alpha.svg must be hosted on the same domain as the .html file, otherwise the inner DOM of the object will be inaccessible.
Important thing to run this HTML, you need host HTML file to web server like IIS, Tomcat
