Browser exclusion
December 12, 2016 12:00 AM
Hey Folks,
Our employees do have two Options to use our LMS and the WBT of it.
While everything is working fine with Internet Explorer, we do have some trouble with Firefox...
But that doen't matter anyway.
What i Need to know, is how a jascript needs to look like, that would set a variable (e.g. "var_usesIE") to true in case of Using the Internet Explorer. Everything else following is easy for me...
Since I read this thread http://trivantis.com/blog/browser-detection-lectora/
I'd like to ask would this work?:
if( navigator.userAgent.match(/Internet Explorer/i)
{ var_usesIE.set(“true”);
} else {
var_usesIE.set(“false”);
}
It would be grateful if somebody could provide the right script since my Javascript Skill are limited.
Thanx a lot!
Kind regards
Sebastian

Hey Darrel,
Thank you very much, that was exactly what I was looking for!
Here is a script that will detect a Microsoft browser (IE/Edge) and assign "true" to a Lectora variable usesIE. "False" will be assigned for any other browser.
// Get IE or Edge browser version
var version = detectIE();
if (version === false) {
console.log("Not IE/EDGE");
VarusesIE.set("false");
} else if (version >= 12) {
console.log('Edge' + version);
VarusesIE.set("true");
} else {
console.log('IE' + version);
VarusesIE.set("true");
}
// add details to debug result
console.log(window.navigator.userAgent);
/**
* detect IE
* returns version of IE or false, if browser is not Internet Explorer
*/
function detectIE() {
var ua = window.navigator.userAgent;
// Test values; Uncomment to check result …
// IE 10
// ua = 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)';
// IE 11
// ua = 'Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko';
// Edge 12 (Spartan)
// ua = 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36 Edge/12.0';
// Edge 13
// ua = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2486.0 Safari/537.36 Edge/13.10586';
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
// IE 10 or older => return version number
return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}
var trident = ua.indexOf('Trident/');
if (trident > 0) {
// IE 11 =undefined
return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}
var edge = ua.indexOf('Edge/');
if (edge > 0) {
// Edge (IE 12+) => return version number
return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}
// other browser
return false;
}
Original script found here.
In the zip file the script is detect.js.
There is also just the reserved Lectora 'BrowserType' variable that will give you the name of the browser being used. This might be sufficient for your needs instead of using a script.
