js、checkbox求助
现有代码

function dsubmitStory(){
????if($("#u_tag").val()?==""?||?$("#u_tag").val()?=="最少要入,用“,”分隔"){
????????alert("不能空!");
????????return?false;
????}else{
????????var?t?=?$("#u_tag").val().split(",");
????????if(t.length<2){
????????????alert("最少入！");
????????????return?false;
????????}else?if(t.length>=2&&t.length<=3){
????????????for(var?j=0;j<t.length;j++){
????????????????if(t[j].length>20){
????????????????????alert("度不能超20!");
????????????????????return?false;
????????????????}
????????????}
????????}else?if(t.length>3){
????????????alert("最多只能入三!");
????????????return?false;
????????}
????????//验证通过执行
????????//document.addStory.submit();?
????}
document.addStory.submit();?
}

以及

<c:forEach var="p" items="${TagList}" varStatus="vs">
                            <td  valign="top">
                            <c:if test="${vs.index!=0}"><div class="form-ul-left"></div></c:if>
                                <div class="form-ul-div">
                                    <ul class="form-ul">
                                        <li><input class="form-ul-li-input" type="checkbox" value="${p.id}" name="ftagid" id="t_${p.id}">${p.tag}</li>
                                    </ul>
                                </div>
                            </td>
                            </c:forEach>

现在我想要在js里面加上对checkbox的验证，条件是至少选择一个复选框，否侧弹出验证不通过的提示，自己弄了一下午了，求助啊 JavaScript HTML checkbox
[解决办法]

  function  validate(){ 
 
     var check = false;
     $(".form-ul-li-input").each(function(){
       var checkBox =  $(this).attr("checked");
       if(checkBox == true){
         check  = true;
         return ;
       }
     }
       );

     if(!check){alert("验证不通过")}
}

jqeury我自己用起来不是很精通。上面代码应该没问题，你自己在修饰一下
