C++下操作字符串的超级容易类~~~~~[4]

  jstring& jsparams=jsurl.substr(pos+1,jsurl.getlength()).lower();  
  while(jsparams)
  {
   pos=jsparams.indexof("page=");
   if(pos==-1)
    break;
   if(pos==0)
   {
    page=jsparams.substr(5,jsparams.getlength()).number();
    break;
   }
   pos=jsparams.indexof("&");
   if(pos==-1)
    break;
   jsparams=jsparams.substr(pos+1,jsparams.getlength());
  }
 }
 cout<<page;
 cout<<"\n\n\n\n";
 return 0;
