或者 ps;οnsubmit=“reutrn false”
onsubmit:当提交表单时执行一段 JavaScript,则return false表示禁止表单提交.

<form class="form-inline" action="/super_manage/hongren_submitl/" method="post" style="margin-bottom: 10px" onsubmit="return false">
        <div class="form-group">
            <div class="col-sm-offset-2 col-sm-6">
                <button type="submit" class="btn btn-primary" onclick="saveProduct()">保 存</button>
            </div>
        </div>
</form>




    function saveProduct() {
            $.ajax({
                url: $("form").attr("action"),
                data: $("form").serialize(),
                type: "POST",
                dataType: "json",
                success: function (data) {
                    if (data['is_succ']==1) {
                        window.location.href = '/super_manage/unchecked_hongren_list/';
                    } else {
                        $(".alert").html(data["error_msg"]);
                        showMsg(data.error_msg);
                    }
                },
                error: function () {
                    showMsg("网络繁忙,请重试或稍后再试");
                }
            });
    }
