AjaxZip3 = function(){};

// AjaxZip3 = function(){};

test.html:26 Uncaught ReferenceError: AjaxZip3 is not defined

ajaxzip3-source.js:33とは？

AjaxZip3.VERSION = '0.51';

test.htmlの26行目とは？

 <input type="text" name="yubin51" size="10" maxlength="8" 
             onkeyup="AjaxZip3.zip2addr(this,'','region51','addr51');">

AjaxZip3 = '' に変更してみると？

Uncaught TypeError: AjaxZip3.zip2addr is not a function
    at HTMLInputElement.onkeyup (test.html:20)
