javascript - How can I create a constructor for a static library -

i'm using introjs library.

see original code here.

i want able write var = new introjs() rather call start() method.

how can achieve that?

why not wrap factory introjs provides , call start on in wrapper?

you can externally (untested):

var introjswrapper = function(targetelm) {     var ijs = introjs(targetelm);     ijs.start();     return ijs; }; 

or can inside fork of introjs code exposing property of main function, e.g.:

var introjs = function (targetelm) {     if (typeof (targetelm) === 'object') {     // ... } introjs.autostart = function(targetelm) {     var ijs = introjs(targetelm);     ijs.start();     return ijs; }; 

note in introjs, main function thin parameter-testing/changing wrapper around internal constructor. calling indirectly invokes constructor. there no need access internal constructor function directly, far can see.
