html - Add onclick event to SVG element -


i found example in svg tutorial, explains how can use onclick event handler svg element. looks code below:

 <svg xmlns='http://www.w3.org/2000/svg' version='1.1' height='600' width='820'>   <script type="text/ecmascript"><![cdata[  function changerect(evt)  {  var svgobj=evt.target;  svgstyle = svgobj.getstyle();  svgstyle.setproperty ('opacity', 0.3);  svgobj.setattribute ('x', 300); } ]]> </script>  <rect onclick='changerect(evt)' style='fill:blue;opacity:1' x='10' y='30' width='100' height='100' />  </svg>

however doesn't seem work. nothing happens when click on element.

perhaps important mention fact displaying svg inside php script, using echo. content generated php script brought page using ajax and:

 xmlhttprequest()

could perhaps have it? lot help.

it appears of javascript must included inside of svg run. unable reference external function, or libraries. meant code wass breaking @ svgstyle = svgobj.getstyle();

this attempting.

<?xml version="1.0" standalone="no"?> <!doctype svg public "-//w3c//dtd svg 1.1//en" "http://www.w3.org/graphics/svg/1.1/dtd/svg11.dtd"> <svg xmlns='http://www.w3.org/2000/svg' version='1.1' height='600' width='820'>  <script type="text/ecmascript"><![cdata[     function changerect(evt) {         var svgobj=evt.target;         svgobj.style.opacity= 0.3;         svgobj.setattribute ('x', 300);     } ]]> </script>  <rect onclick='changerect(evt)' style='fill:blue;opacity:1' x='10' y='30' width='100'height='100' /> </svg>

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
