Question

I’m trying for a while now to get started with JQuery, but again I’m stuck with regex.
What I want to achieve is this:

• Bookmarklet that uses JQuery or JS
• Bookmarklet looks at current URL I’m at
• Check If URL contains an ID like this: ‘1.1188651’ (1digit+period+7digits)
• If Check OK then copy ID in clipboard or display in new window

Can this be done?
I’m very thankful for your help.

Answer 1

RegEx to test the url:

/\d\.\d{7}/.test(sUrl);

Also see this jsfiddle.

To also get the id:

var sId = /\d\.\d{7}/.exec(sUrl);
if (sId !== null) {
    alert(sId);
}

Also see my second jsfiddle.

=== UPDATE ===

So the bookmarklet could be:

javascript:if((sId=/\d\.\d{7}/.exec(window.location.href))!==null){alert(sId);}

javascript: prefix for the bookmarklet;
window.location.href is the current url;
sId=/\d\.\d{7}/.exec(...) saves the regex result in sId;
if(>regex<!==null) {...} checks if regex has matched;
alert(sId); shows the id in a “new window”.

=== UPDATE 2 ===

If the format is 12345678 (eight digits) and you want a . after the first digit, you can use following bookmarklet:

javascript:if((aId=/(\d)(\d{7})/.exec(window.location.href))!==null){alert(aId[1]+'.'+aId[2]);}
