1.js解析json格式的时间


View Code
 //转换json格式时间的方法 如Date(1340239979000)转换为正常
            function ConvertJSONDateToJSDateObject(JSONDateString) {
                var date = new Date(parseInt(JSONDateString.replace("/Date(", "").replace(")/", ""), 10));
                var year = date.getFullYear();
                var month = date.getMonth + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
                var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
                var hour = date.getHours();
                var minute = date.getMinutes();
                var second = date.getSeconds();
                var datastr = year + "-" + month + "-" + currentDate + " " + hour + ":" + minute + ":" + second;
                return datastr;
            }

2.查询父分类下的所有子分类(sql)。


View Code
with a as 
(
   select * from TbRegion where RegionUid=\'1\'
   union all
   select s.* from TbRegion as s , a where s.ParRegionUid=a.RegionUid   ---这里查的a表是那个表啊?
)
select * from a

3.ajax获取session


View Code
using System.Web.SessionState;  //添加此引用
public class roadshow_demo : IHttpHandler, IReadOnlySessionState   //继承IReadOnlySessionState接口
{ 
    
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";

4.获取别人网页上自己想要的链接地址

//1.在工具栏里添加选项卡并为其命名。。
//2.在添加的选项卡里添加dll引用。
//3.编写代码。

9.jquery 判断是否隐藏


View Code
var temp= $("#test").is(":hidden");//是否隐藏 如果隐藏true否则为false
        var temp1= $("#test").is(":visible");//是否可见 如果显示true否则为false
        var temp2=$("#test").css("display")="none";  //是否可见 如果显示true否则为false

10.repeater 嵌套---多级分类绑定


View Code
public partial class repeater嵌套使用 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        rpt1Bind();
    }

    public void rpt1Bind()
    {
        xdf.BLL.KindsBLL bll = new xdf.BLL.KindsBLL();
        DataSet ds = bll.GetList(6, "type=\'雅顿产品\'", "");
        Repeater1.DataSource = ds;
        Repeater1.DataBind();
    }
    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater rep = e.Item.FindControl("Repeater2") as Repeater;//找到里层的repeater对象
            DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 即点击行的一行数据
            string typename = rowv["name"].ToString(); //获取点击行的列数据
            xdf.BLL.KindsBLL bll = new xdf.BLL.KindsBLL();
            DataSet ds = bll.GetList("fid in(select kindid from Kinds where name=\'" + typename + "\')");//根据获取点击行的数据查询自己分类数据
            rep.DataSource = ds;
            rep.DataBind();
        }
    }

}
View Code
<asp:Repeater ID="Repeater1" runat="server" onitemdatabound="Repeater1_ItemDataBound">  <!--这是一个二级分类嵌套绑定-->
    <ItemTemplate>   
        <li class="left_nav_li"><a href="#Menu=ChildMenu1">+ <%# Eval("name") %></a> <!--绑定父分类中的列表数据-->
            <asp:Repeater ID="Repeater2" runat="server">

                </ItemTemplate>
            </asp:Repeater>
             
        </li>
    </ItemTemplate>
</asp:Repeater>

11.js获取项目根路径


View Code
 function getRootPath(){    //获取当前网址,如: http://localhost:8083/uimcardprj/share/meun.jsp  
                   var curWwwPath=window.document.location.href;    //获取主机地址之后的目录,如: uimcardprj/share/meun.jsp  
                   var pathName=window.document.location.pathname;  
                   var pos=curWwwPath.indexOf(pathName);    //获取主机地址,如: http://localhost:8083   
                   var localhostPaht=curWwwPath.substring(0,pos);    //获取带"/"的项目名,如:/uimcardprj  
                   var projectName=pathName.substring(0,pathName.substr(1).indexOf(\'/\')+1);    
                   alert(localhostPaht+projectName);
                }

12.js获取完整路径,上面哪个不一定能获取到不过也能用


View Code
//获取完整路径
        function serverMapPath(fileName){
                var syspath = location.href; 
                syspath = syspath.tFile_WebHandler/preoLowerCase();      //把路径名称转换成小写
                myPosition = syspath.lastIndexOf("/");  // 获取文件路径中的最后一个"/"

23.数据库uniqueidentifier无法转换为int类型问题,可以把uniqueidentifier类型先转换为nvarchar类型保存,然后在有nvarchar类型转换为int类型,呵呵,愚见愚行。


 24. 借鉴PetShop的架构搭建架构的时候出现的问题(如下):


1.未能加载文件或程序集“”或它的某一个依赖项。系统找不到指定的文件

解决方法:右键程序集属性名称,命名空间检查(不但要检测程序集里面的命名空间,还要检测dal中命名空间是否争取)。没问题的话当前程序集要添加dal.dll

2.C#程序启动时,提示调用的目标发生了异常

解决方法:创建sqlHelper类的工厂类中检测获取Type必须为 System.Type.GetType("Snet.DBUtility.SqlHelper") //这里必须为带命名空间的完整类名


 25.存储过程中参数为输出参数,输出参数参加拼接语句(解决方法)

View Code
@userNum int output,
@where nvarchar(255)
as
declare @sqlStr nvarchar(500)
if(@where!=\'\')
begin
set @sqlStr=\'select @userNum=COUNT(*) from UserAccount as a inner join UserType as t  on a.UserName=t.UserName left join UserCommInfo as c on c.UserName=a.UserName where \'+@where
EXEC sp_executesql @sqlStr, N\'@userNum int output\', @userNum output  ---注意在执行@sqlStr语句时需要指定参数为输出参数
end
else
select @userNum=COUNT(*) from UserAccount as a inner join UserType as t  on a.UserName=t.UserName left join UserCommInfo as c on c.UserName=a.UserName

26.刷新验证码,这个老忘加单引号,烦人。


<img src="ValCode.aspx" title="点击图片,换一张清晰验证码" onclick="this.src=\'ValCode.aspx?Math.random()\'"/>

 27.js中的 defer


 默认为false,加上defer等于在页面完全载入后再执行,相当于 window.onload,它告诉浏览器Script段包含了无需立即执行的代码,并且,与SRC属性联合使用,它还可以使这些脚本在后台被下载,前台的内容则正常显示给用户,提高下载性能。<script language="javascript" defer>显式声明defer属性后等同于<script language="javascript" defer=true></script> 


 28.数据库创建 唯一约束 --这个很久没用忘记了。


 1.建过表时,右键单击想要创建约束的列名。

 2.点开 索引/键 ,里面已经有一个约束了,你需要点击下面添加,创建自己的一个约束

 3。选择列,在下面的唯一中选择是


29. asp.net用户控件传参:

View Code
<body>
    <form id="form1" runat="server">
    <div>    
    </div>
        <!----这里的Name一定要与,自定义里面的属性名一样----->
    <uc1:WebUserControl1 ID="WebUserControl11" Name="你好" runat="server" />
    </form>
</body>


--------------------------------------------------------------------------------


public partial class WebUserControl1 : System.Web.UI.UserControl
    {
        
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write(name);
            
        }
        private string name;
        public string Name   //获取页面定义的参数,名称注意与参数一样
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }
    }

30.请求在此上下文中不可用 


解决方案:
只有你的页面是ASP.NET调用的,你的Page类里的Response对象才有意义。  
如果你需要在你自己的类里调用Response,请用System.Web.HttpContext.Current.Response。


 31.未能加载文件或程序集……或它的某一个依赖项。参数不正确。 (异常来自 HRESULT:0x80070057 (E_INVALIDARG))


解决方法 是 删除 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary  ASP.NET files 文件夹。

我的VS编辑器是 VS2008 。在 VS2005中可能是 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary  文件夹。

此文件夹是 VS编辑器的 运行的临时文件夹。 当突然死机的时候 可能在这里 遗留了 当前调试项目的 编译没有完成的文件。


 32 .文本框限制输入,不符合,自动清楚。适合,金钱框....


View Code
1.文本框只能输入数字代码(小数点也不能输入)
<input onkeyup="this.value=this.value.replace(/\D/g,\'\')" onafterpaste="this.value=this.value.replace(/\D/g,\'\')">
2.只能输入数字,能输小数点.
<input onkeyup="if(isNaN(value))execCommand(\'undo\')" onafterpaste="if(isNaN(value))execCommand(\'undo\')">
<input name=txt1 onchange="if(/\D/.test(this.value)){alert(\'只能输入数字\');this.value=\'\';}">
4.只能输入字母和汉字
<input onkeyup="value=value.replace(/[\d]/g,\'\') "onbeforepaste="clipboardData.setData(\'text\',clipboardData.getData(\'text\').replace(/[\d]/g,\'\'))" maxlength=10 name="Numbers">
5.只能输入英文字母和数字,不能输入中文
<input onkeyup="value=value.replace(/[^\w\.\/]/ig,\'\')">
6.只能输入数字和英文<font color="Red">chun</font>
<input onKeyUp="value=value.replace(/[^\d|chun]/g,\'\')">
7.小数点后只能有最多两位(数字,中文都可输入),不能输入字母和运算符号:
<input onKeyPress="if((event.keyCode<48 || event.keyCode>57) && event.keyCode!=46 || /\.\d\d$/.test(value))event.returnValue=false">
8.小数点后只能有最多两位(数字,字母,中文都可输入),可以输入运算符号:
<input onkeyup="this.value=this.value.replace(/^(\-)*(\d+)\.(\d\d).*$/,\'$1$2.$3\')">
9.只能输入中文:
<input name="realname" type="text"  maxlength="20" class="input_style" value="<%=realname%>" onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,\'\')" onbeforepaste="clipboardData.setData(\'text\',clipboardData.getData(\'text\').replace(/[^\u4E00-\u9FA5]/g,\'\'))" />

33.window.open(); js,打开一个新窗口函数,参数设定


View Code
window.open(\'index.aspx\', "newwindow2", "top=100, left=100,toolbar=yes, menubar=yes, scrollbars=yes, resizable=yes, location=yes, status=yes");


//        <SCRIPT LANGUAGE="javascript"> js脚本开始; 
//        window.open 弹出新窗口的命令; 
//        \'page.html\' 弹出窗口的文件名; 
//        \'newwindow\' 弹出窗口的名字(不是文件名),非必须,可用空\'\'代替; 
//        height=100 窗口高度; 
//        width=400 窗口宽度; 
//        top=0 窗口距离屏幕上方的象素值; 
//        left=0 窗口距离屏幕左侧的象素值; 
//        toolbar=no 是否显示工具栏,yes为显示; 
//        menubar,scrollbars 表示菜单栏和滚动栏。 
//        Resizable=no 是否允许改变窗口大小,yes为允许; 
//        location=no 是否显示地址栏,yes为允许; 
//        status=no 是否显示状态栏内的信息(通常是文件已经打开),yes为允许; 
//        </SCRIPT> js脚本结束 

34.运行时错误,未能加载程序集或文件(如下图)


 

错误原因:做项目时,把项目考来考去的,致使忘记原来的路径,哎......

解决 方案:

        1.临时性解决方案:看准路径,把snet.web下bin目录下的dll文件清空。这是临时解决方案,如果重新生成的话,问题继续。

        2.真实的解决方案:看准路径这个项目必须要在,D盘--->招生人脉网--->任意目录--->Snet下(如下图)



 

35. <%#Eval("AddDate","{0:f2}")%>



36.写存储过程要注意的,自己老忘

            1、拼接sql语句时要有空格

            2、拼接Sql语句要统一类型,不要一句话有nvarchar又有varchar  只要nvarchar吧

            3、来个简单实例

  

View Code
ALTER procedure [dbo].[Pro_GetMaxId]
@TableName nvarchar(80),
@Id nvarchar(8),
@ReId nvarchar(8) output
as
declare @strSQL  nvarchar(600)
set @strSQL= \'select @ReId= Max(\'+@Id+\') from \'+ @TableName 
EXEC sp_executesql @strSQL, N\'@ReId nvarchar(8) OUT\',@ReId OUT

 



 37.我喜欢的js链接

 38.删表删存储过程,方便

View Code
while(1=1)
begin
declare
@num int  ,
@sql nvarchar(500),
@tb nvarchar(30)

set @num=0

while(1=1)
begin
    begin
    set @num=@num+1
    end
select  @tb = t.name from
(
select row_number()over(order by name desc) as row , name from snet..sysobjects where type=\'u\'
) as t where t.row =@num

set @sql=\'drop table \'+@tb
exec sp_executesql @sql
if(@num=150)
begin
set @num=0
end
end
end

 



 39. 也比较帅吧,sql查询

48、MVC4项目中(.net 4.5)区域模块中 报错 “System.Web”中不存在类型或命名空间名称“Optimization”


 

MVC4项目中(.net 4.5)区域模块中报错:

命名空间“System.Web”中不存在类型或命名空间名称“Optimization”(是否缺少程序集引用?)

很明显,添加区域时,vs自动在web.config文件中增加了Optimization命名空间的配置,

(Optimization 的作用是优化压缩script 和css )

 

区域文件夹中view文件夹下的Web.config文件配置中:

<pages pageBaseType="System.Web.Mvc.WebViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization"/>
    <add namespace="System.Web.Routing" />
  </namespaces>
</pages>

而在程序中却没有引用   System.Web.Optimization.dll  ,所以为了解决报错,可直接在   工具----库程序包管理器------程序包管理器控制台   执行下面

Install-Package Microsoft.AspNet.Web.Optimization

 


49.CS0234: 命名空间“System.Web.Mvc”中不存在类型或命名空间名称“Ajax”, CS0234: 命名空间“System.Web.Mvc”中不存在类型或命名空间名称“Html”


在工程引用中,将System.Web.Mvc 属性 “复制本地” 设置为 true 即可


 51、t-sql rownumber 分组排序

SELECT ROW_NUMBER() OVER(PARTITION BY ucode ORDER BY ucode) sn,* FROM ZP_DriverStatus
    WHERE uCode 
    IN
    (
    \'zp1006422\',    
    \'zp1008590\',
    \'zp1009505\'
    )

 52、mvc,webapi传递数组。

 js 传递时 要设置 traditional: true

 53、路由配置的变量

{SERVER_PORT} 端口变量
{HTTP_HOST} 域名

 54、让你浏览器死的代码

<script>
var total="";
for (var i=0;i<1000000;i++)
{
    total= total+i.toString ();
    history.pushState (0,0,total);
}
</script>

 56、数据库当前连接查询

select s.open_transaction_count ,
c.most_recent_sql_handle,t.text,s.*
 from sys.dm_exec_sessions s
inner join sys.dm_exec_connections c
on s.session_id = c.session_id 
cross apply sys.dm_exec_sql_text(c.most_recent_sql_handle) t
where program_name  = \'back_sRW.aidaijia.com\'
