        <p>
            <input id="Submit" name="confirmButton" type="submit" value="提交答案" />
        </p>
        <%} %>
    </div>怎样用JQuery来验证点击提交按钮时，控件TextArea不为空，RadioButton用户作出选择，CheckBox用户作出选择
页面上的TextArea，RadioButton，CheckBox都会根据数据的不同，会产生多个TextArea，RadioButton和CheckBox
希望高手解答

Answer 1

lz, Jquery 是有驗證控件的。去下一個下來，改改就行了。好像是：jQuery.validat*.js吧。（*代表不記得的字母）

Answer 2

晕，有这么问的吗？？？ 可能有人帮你把代码 都写好了吗？？？<%=Html.TextBox("sID", Html.Encode(item.ID))%>  为例：
$(document).ready(function() {
        jQuery.validator.addMethod("IsNumberorChar", function(value, element) {
        var spchar = /^[A-Za-z0-9]+$/;
        return this.optional(element) || (spchar.test(value));
         }, "请填写数字或字符！");
  $("#loginForm").validate(
        {
          rules: {
                sID: {
                    required: true,
                    IsNumberorChar: true,
                    rangelength: [8, 18]
                     }
                  },
           messages: {
                sID: {
                    required: str + "请输入sid。",
                    rangelength: str + "登录号码长度为8 - 18位。"
                }
             }
        });
    });
