Consider this code:
var myregexp = "\\*(.+)"; // set from another subsystem, that's why I'm not using a literal regexp
var input = "Paypal *Steam Games";
var output = input.match(new RegExp(myregexp, 'gi'), "$1");
The output is ["*Steam Games"], but I would like it to be just ["Steam Games"].
What is wrong?
PS A great resource I found today: http://regex101.com/#javascript
match doesn’t accept a second argument.
Since you have the global flag set (and I assume it’s intentional), you’ll need exec to find all of the first groups:
var m;
while ((m = re.exec(input)) {
alert(m[1]); // Get group 1
}
var str = "Paypal *Steam Games";
var reg = /\w+\s?\*(\w+\s?\w+)/; // or your exp will work too `/\*(.+)/;`
console.log(reg.exec(str)[1]); // result Steam Games
You'll get Steam Games from your string with help of /\w+\s?\*(\w+\s?\w+)/ exp
In JavaScript there are three main RegExp functions:
exec A RegExp method that executes a search for a match in a string. It returns an array of information.
match A String method that executes a search for a match in a string. It returns an array of information or null on a mismatch.
test A RegExp method that tests for a match in a string. It returns true or false.
