問題解答
回答1：window.onload方法被覆蓋了，把兩塊代碼放一塊，或者用addEventListener
回答2：GlobalEventHandlers.onload
貌似window.onload在同一個(gè)html引入的js文件里只能寫一次。
你這樣寫試試：（我只是簡(jiǎn)略的寫了代碼，沒測(cè)試，自己測(cè)測(cè)改改吧）
window.onload = function(){//父選項(xiàng)卡控制tab('tab_t','li','tab_c','a_b','act','p','onclick');//子選項(xiàng)卡控制tab('bab_t','li','bab_c','b_b','bct','p','onclick'); }; function tab(tab_t,tab_t_tag,tab_c,tab_c_li,tab_t_li,tag_c_tag,evt){var tab_t = document.getElementById(tab_t);var tab_t_li = tab_t.getElementsByTagName(tab_t_tag);var tab_c = document.getElementById(tab_c);var tab_c_li = document.getElementsByClassName(tab_c_li);var len = tab_t_li.length;var i=0;for(i=0; i<len; i++){ tab_t_li[i].index = i; tab_t_li[i][evt] = function(){for(i=0; i<len; i++){ tab_t_li[i].className = ’’; tab_c_li[i].className = ’hide ’+tab_c_li+’’;}tab_t_li[this.index].className = ’’+tab_t_li+’’;tab_c_li[this.index].className = ’’+tab_c_li+’’; }} }
