Failsafe load for attaching stylesheet

Published in: JavaScript 

URL: http://notes.natbat.net/2006/12/06/trycatchjavascript/

The setTimeout ensures that if there is an issue attaching the link to the bottom of the head (e.g. if the head hasn’t finished loading when the link is trying to be attached) it retries after 100ms. Resetting the css variable to null avoids potential memory leaks.


Plain TextExpand 
  1. function setCSS(css) {
  2. 	try {
  3. 		// append stylesheet to alter
  4. 		document.getElementsByTagName("head")[0].appendChild(css);
  5. 	} catch (e) {
  6. 		setTimeout(function(){setCSS(css)}, 100);
  7. 	}
  8. }
  9.  
  10. // create CSS element to set up the page
  11. var css = document.createElement("link");
  12. css.setAttribute("href",path/to/stylesheet);
  13. css.setAttribute("rel","stylesheet");
  14. css.setAttribute("type","text/css");
  15.  
  16. // attempt to add the css and then keep trying till we do
  17. setCSS(css);
  18. css = null;
