tab_1 tan_2均是鼠標移出后增加空類（this.className+=''），所以實際上鼠標移出后tab_1上仍有selected屬性，故點擊tab_2仍顯示tab_1的值，故在點擊tab_2時需將tab_1的selected類移除，可將
addEvent('tab_2','click',function(){
getDOM('search_tab').className='search-list';
});
更改為
addEvent('tab_2','click',function(){
getDOM('search_tab').className='search-list';
this.className="selected";
getDOM('tab_1').className="";
});
并建議添加代碼，避免鼠標未點擊的情況下移開search_tab仍為顯示狀態：
addEvent('search_tab','mouseout',function(){
this.className='search-list';//注意：類名前加空格
});
