returnthis;
};
myClass.prototype.toAlert=function()

this.instance.callback();//thesecondmethodtocallprototypefunction.

//thethirdmethodtocallprototypefunction.
document.write("<ahref='javascript:void(0);'onclick='"+this.instanceName+".callback();'>instancecallprototypefunction.</a>")
};
myClass.prototype.callback=function()
