使用javascript验证gridview中的用户控件

标签: javascript asp.net gridview

我是javascript的新手,我想用它来验证gridview(radgrid listview)中的用户控件。

这是我到目前为止所做的,但是javascript没有解雇。

我不想使用Range验证器,因为验证器错误消息即使在未显示时也会占用一些空间,并且在我的gridview中看起来不太好。

提前感谢您的帮助

HTML代码:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="sks_Creation.ascx.cs" Inherits="Sapphire.Control.Assessment.sks_Creation" %>

<asp:UpdatePanel ID="updPnl" runat="server">
<ContentTemplate>

<script type="text/javascript">
        function validate() {
            var grid = document.getElementById("<%= LV.ClientID%>");
        for (var i = 0; i < grid.rows.length - 1; i++) {

            var Mark = $("input[id*=txtMark]")
            var ValMark = $("input[id*=lblValMark]")

            if (Mark == 0) {
                alert("Mark should be greater than 0");
                ValMark = "Mark should be greater than 0";
                return false;
            }
        }
    }
</script>

<tlk:RadListView ID="LV" runat="server" Width="99%" OnNeedDataSource="LV_NeedDataSource" OnItemDataBound="LV_ItemDataBound" AllowPaging="true" ItemPlaceholderID="QuestionContainer">
