Question

Let’s say I have a string like this

Hello World, I am xyz, How are you ?

And I need all the characters in the string that comes after last comma. Which is here

How are you?

How can I do this ?

Note : Here space in the beginning should not come.

Also I need the remaining string into another variable which will be

Hello World, I am xyz

Note: here comma in the end should not come.

Answer 1

You can do that with a simple regex:

s   = 'Hello World, I am xyz, How are you ?';
hay = s.replace(/.*,/, '');
// " How are you ?"

Or, if you want to take care of the leading space at the same time:

s   = 'Hello World, I am xyz, How are you ?';
hay = s.replace(/.*,\s*/, '');
// "How are you ?"

If you want the first part and the “How are you ?” part, then you could use match instead of replace:

var m = s.match(/^(.*),\s*(.*)$/);
// m[1] is "Hello World, I am xyz"
// m[2] is "How are you ?"
