copied!<p>Hi i have bookmarklet code to load a scripts from a mirrored backup location if my main hosting goes down, it works but i want to know the best way to do this as i know the current way i am doing it is probably not the best way. </p> <p>(<strong>this is a example of my backup bookmarlet code expanded</strong>) </p> <pre class="lang-js prettyprint-override"><code>javascript: (function () { var scriptname = 'testscript'; function checkServerStatus() { var v = setTimeout(function () { loadscript('backupserver.hardiman.co.nz') }, 4500); var a = document.body.appendChild(document.createElement('img')); a.onload = function () { clearTimeout(v); loadscript('screepts.com') }; a.src = 'http://screepts.com/ping.gif?' + Math.random(); } checkServerStatus(); function loadscript(b) { var a = document.createElement('script'); a.type = 'text/javascript'; a.src = 'http://' + b + '/bm/' + scriptname + '.js?' + Math.random(); document.getElementsByTagName('head')[0].appendChild(a) } })();` </code></pre> <p>And this is it wrapped up as a bookmarklet : </p> <pre class="lang-html prettyprint-override"><code><a href="javascript:%28function%28%29%7Bvar c%3D'testscript'%3Bfunction checkServerStatus%28%29%7Bvar v%3DsetTimeout%28function%28%29%7Bloadscript%28'backupserver.hardiman.co.nz'%29%7D,4500%29%3Bvar a%3Ddocument.body.appendChild%28document.createElement%28'img'%29%29%3Ba.onload%3Dfunction%28%29%7BclearTimeout%28v%29%3Bloadscript%28'screepts.com'%29%7D%3Ba.src%3D'http://screepts.com/ping.gif%3F'%2BMath.random%28%29%3B%7DcheckServerStatus%28%29%3Bfunction loadscript%28b%29%7Bvar a%3Ddocument.createElement%28'script'%29%3Ba.type%3D'text/javascript'%3Ba.src%3D'http://'%2Bb%2B'/bm/'%2Bc%2B'.js%3F'%2BMath.random%28%29%3Bdocument.getElementsByTagName%28'head'%29%5B0%5D.appendChild%28a%29%7D%7D%29%28%29%3B">Test Script</a> </code></pre> <p>Any help or advice on loading a script from a backup server would be greatly appreciated..</p> <hr> <p>Okay sorry i should have been more specific on the question. Since my hosting went down i was able to test the above code properly. I think the only thing i need to do is parse what server was loaded to the script. </p>
