兩個Input公用一個函數，根據參數做處理<input?type="text"??name="username"?onblur="validation('username')"?onfocus="clearvalidation()"></td> <input?type="text"??name="email"?onblur="validation('email')"?onfocus="clearvalidation()"></td>本想通過object={key:value}方式吧這個參數傳出去，且key ?value都是形參,如果按照下面那樣的話，結果就錯了，求正確書寫方式，謝謝。function?validation(yzstr){ ????var?valuestr=document.getElementsByName(yzstr)[0].value; ????tests({yzstr:valuestr}); } function?tests(myobj){ ????for(var?i?in?myobj){ ????//下面錯誤，實際為myobj.yzstr ????????if(i=="username"){ ????????????console.log(myobj.usernmae) ????????}if(i=="email"){ ????????........... ????????} ????} ??? }
