Question

This didn’t happen until I have added jQuery.

function mfunc() {}
mfunc.prototype.create = function(value) { 
alert("hi");
}

Script before the closing body tag:

$(document).ready(function(){
 var mfunc = new mfunc();
    alert("hi");
    alert(mfunc.create("hello"));

 });

I get the following error in firebug:

mfunc.create is not a function

Thanks in advance.

You are shadowing your prototype function! Your original function is called mfunc, but then you are using that same variable name to refer to a new instance. Use a different variable name:

$(document).ready(function(){
    var mobj = new mfunc();
    alert("hi");
    alert(mobj.create("hello"));
});
