CheckBox （全选切换，判断全选）

<input type=checkbox name=mm value=a onclick="checkItem(this, 'mmAll')"><br><input type=checkbox name=mm value=b onclick="checkItem(this, 'mmAll')"><br><input type=checkbox name=mm value=c onclick="checkItem(this, 'mmAll')"><br><input type=checkbox name=mm value=d onclick="checkItem(this, 'mmAll')"><br><input type=checkbox name=mm value=e onclick="checkItem(this, 'mmAll')"><br><br><input type=checkbox name=mmAll onclick="checkAll(this, 'mm')">全选与不全选的切换 <mce:script language=Javascript><!--function checkAll(e, itemName){  var aa = document.getElementsByName(itemName);  for (var i=0; i<aa.length; i++)   aa[i].checked = e.checked;}function checkItem(e, allName){  var all = document.getElementsByName(allName)[0];  if(!e.checked) all.checked = false;  else  {    var aa = document.getElementsByName(e.name);    for (var i=0; i<aa.length; i++)     if(!aa[i].checked) return;    all.checked = true;  }}// --></mce:script> 

var checkDelAll = function(){var count=0;for(var i=0;i<chooseForm.elements.length;i++){var e = chooseForm.elements[i];if (e.type == 'checkbox' && e.checked==true && e.name!='chooseAll') {count++;}}if(count==0){alert("请选中需要删除的数据");return false;}if(confirm("确认要删除吗？")){chooseForm.action = 'deleteUserPhoto.action';chooseForm.submit();}else{return false;}} 

如果页面使用 <s:iterator value=""> 同样可以 IE FF 通用
