jsp和js两种方式取到表单数据

Jsp方式取得：
<script type="text/javascript">function check(){ var gender = document.getElementsByName("gender");// var gender = document.selectform.gender;一样能拿到gender这个对象，其实是个数组！ for(i=0;i<gender.length;i++){  if(gender[i].checked)  alert(gender[i].value); }  var animal = document.getElementsByName("animal");// var gender = document.selectform.animal; for(i=0;i<animal.length;i++){  if(animal[i].checked)  alert(animal[i].value); }  var select = document.getElementById("selected");//拿到一个对象// var select = document.selectform.select; for(i=0;i<select.options.length;i++){  if(select.options[i].selected)  alert(select.options[i].value); } var selectedOption = document.selectform.select.options[document.selectform.select.selectedIndex]; var selectedOptionValue = selectedCategory.value; var hidden = document.getElementById("hidden");//  var hidden = document.selectform.hidden; alert(hidden.value);   return true;}
