validator的验证

通常喜欢这么写验证

<form method="post" data-ajax="false" action="/Shppping/PlaceOrder" id="orderform">
                <a class="btnpay" href="javascript:void(0)" onclick="return checkSubmit();"  id="btnpay">支付</a>
                <a class="btncancel" id="btncancel" href="javascript:void(0)">取消</a>
</form>

然后就是checksubmit方法

    function checkSubmit() {
        var errorMsg = "";
        var sj = $("#ordertime");
        var sfz = $("#orderncerti");
        var dyz = $("#ordernguideCard");
        var lxs = $("#orderntravelAgency");
        var smr = $("#ordername");
        var sjh = $("#orderphone");
        if (sj.length >  && sj.val() == "") {
            errorMsg = "请选择出行日期";
        }
        else if (sjh.length >  && sjh.val() == "") {
            errorMsg = "手机号码不正确";
        }
        else if (smr.length >  && smr.val() == "") {
            errorMsg = "请填写姓名";
        }
        else if (sfz.length >  && sfz.val() == "") {
            errorMsg = "请填写身份证号";
        }
        else if (dyz.length >  && dyz.val() == "") {
            errorMsg = "请填写导游证号";
        }
        else if (lxs.length >  && lxs.val() == "") {
            errorMsg = "请填写旅行社名称";
        }

        else if ($(".Ochooseno1.active").length ==  || $(".Ochooseno2.active").length == ) {
            errorMsg = "请选择支付方式";
        }
        if (errorMsg != "") {
            alert(errorMsg);
            return false;
        }
        //$("#orderForm").submit();
        alert("提交成功");
        return false;
        //return true;
    }

再有就是validate.js的使用
