I have this simple code:
Subscribe today
when the user press on the a tag it takes him to the page subsc.php?English.
My question is how can i get the information after the ? (which is "English" in this example)?
You can try with Regex Positive Lookbehind /(?<=\?).$*/.
var url = '/subsc.php?English';
var r = url.match(/(?<=\?).*$/)[0];
console.log(r);

I am new to javascript and have not much idea about regular expressions. Please help me in understanding the following code.
var r = new RegExp("^.*?https://www\\.facebook\\.com/servlet/SignOn.*$","i");
var content = "https://www.facebook.com/servlet/SignOn?msg=You+are+not+authorized+to+vie…r+level+of+authority.&cm_sp=TopNav-_-servlet-_-MMM&goto=MembersMainMenu%3F";
console.log(content.search(r));// It gives me 0
But when I change the regex to
var r = new RegExp("^.*?https://www\\.facebook\\.com/servlet/SignOn?msg=.*$","i");
console.log(content.search(r));// It gives me -1 , why??
n? means n is optional you need n\?

I have a string I am trying to get the last character with jquery. How would I do that?
var stringTemp = "fieldNameWithIndex_1";
stringTemp.charAt(stringTemp.length-1);
or
stringTemp.slice(-1);
Use .split():
stringTemp.split('_')[1]
