在javascript中也可以模仿jsp取得doGet的參數喔∼ 下面是寫法跟範例： /*取得doGet url中某個名稱變數的值*/  function gup( name ){ name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ) return ""; else return results[1]; } /*使用gup取得doGet參數值，並加到redirect的網址後面*/  if(gup('path') != null && gup('path') != ''){ document.location=document.location=(baseUrl+gup('path')); } else { alert('Sorry, parameter error!'); }
