var t = parseInt(delay.match(/\d+/)[0], 10), 
        unit = "", 
        d = 0; 
switch(delay.match(/[ms]/i)[0]) { 
        case "s": 
                unit = "secondes";

• javascript
• greasemonkey
• alert
• tampermonkey

• 1 Take out the quotes around extern in the alert. alert(extern) else it alerts a string – dievardump Commented Jul 19, 2013 at 11:19

Your alert alerts 'extern' because you alert it as a string.

alert(extern) will alert the good value.

And to make the div visible, just:

document.getElementById('div2').style.display = 'block';
