How to remove part of a string before a “:” in javascript?

Question

If I have a string Abc: Lorem ipsum sit amet, how can I use JavaScript/jQuery to remove the string before the : including the :. For e

Answer 1

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];
