I keep getting the wrong output

[dtyler]

I've created a userAgent sniffing javascript application (for experimental/learning purposes only) and I'm almost finished. But, for the $browser.version, I'm getting the whole userAgent string. I've google'd and google'd and cannot find the answer. Here's my code:\[code\]// contemplate new $browser modulevar $browser, versionOffset, ua = navigator.userAgent;if(ua.toLowerCase().indexOf('opera') > -1) { $browser = { name: "Opera", engine: "Presto", prefix: "-o-", publisher: "Opera Software ASA", version: ua.substring(versionOffset + 6) }}else if(ua.toLowerCase().indexOf('msie') > -1) { $browser = { name: "Internet Explorer", engine: "Trident", prefix: "-ms-", publisher: "Microsoft", version: ua.substring(versionOffset + 5) }}else if(ua.toLowerCase().indexOf('chrome') > -1) { $browser = { name: "Chrome", engine: "WebKit", prefix: "-webkit-", publisher: "Google Inc.", version: ua.substring(versionOffset + 7) }}else if(ua.toLowerCase().indexOf('safari') > -1) { $browser = { name: "Safari", engine: "WebKit", prefix: "-webkit-", publisher: "Apple Computer Inc.", version: ua.substring(versionOffset + 8) }}else if(ua.toLowerCase().indexOf('firefox') > -1) { $browser = { name: "Firefox", engine: "Gecko", prefix: "-moz-", publisher: "Mozilla", version: ua.substring(versionOffset + 8) }}\[/code\]So in my HTML, I'm doing:\[code\]<script> alert($browser.name + " " + $browser.version);</script>\[/code\]But my output in chrome is:[JavaScript Alert]:Chrome ($browser.name)
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.91 Safari/537.4 ($browser.version)But I want, obviously "Chrome 22" or "Chrome 22.0.1229.91"
