there is a problem for UA, if jump by HPMNK, we will not allow to use TC~

then, to paul21:
The script not work to me, but I am also a programmer, I corrected it.
some advise:
don't specify default value for the parameters of functions liked function x(y=0), maybe it needs very high version of js-engine to run, it did not work here to me.
the other problem here to me is "itaLocale undefined", I can see it is a global variable in the itinerary page, but I don't know why it can't be located in the script here to me, maybe lack of privilege?
