System.Web.HttpContext.Current.Request.PhysicalApplicationPath: 获得网站根目录路径
读取xml问题:
DataTable dt= new DataTable ();
dt.ReadXml(System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "Web.sitemap");
运行到最后一句出错:DataTable does not support schema inference from Xml.
所以用下面语句执行:
DataSet ds = new DataSet();
ds.ReadXml(System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "Web.sitemap");
JQuery.Ajax--遍历类成员
$(document).ready(function () {
$.ajax({
type: "GET",
url: "/HOME/GetMenu",
dataType: 'json',
success: function (json) {
var menuplace = $("#leftmenuid");
var data = json.data;
$.each(data, function (n, value) {
});
},
error: function (e) {
alert(e);
}
});
});
---------------------------------------------
--操作查询出来记录的每一个对象
$(".xt").each(function () {
var parentarea = $(this).children().children(0);
//前四个是选项,后两个是问题id和答案id
JudgeOption(parentarea);
}
);
checkbox: var objvalue = $(obj)[$(obj).length - 1].children[1].value;
父目录的前一个兄弟: var objparent = $(obj).parent().parent().prev(".question");

当鼠标移动上去后,加个边框
.mouseseoverstyle{ border:1px solid white}(默认的边框,这样就不会出现鼠标移动到上面后,加上边框出现移动的情况了)
.mouseselected{ border:1px solid green; background-color:#f4f4f4}
------------------------------------
jquery each
$(".dy_box li").each(function () {
$(this).mouseout(function () {
$(this).removeClass("mouseselected");
});
});
找到对象数组,并且通过each,对每个对象操作
---css vertical-align:middle
答案:不起作用的时候,查看 min-height 和 line-height保证它们相同可以解决问题
FORM验证:FormsAuthentication.SignOut()
登陆:
string userroles=string.Empty;
FormsAuthenticationTicket Ticket = new FormsAuthenticationTicket(1, Login1.UserName, DateTime.Now, DateTime.Now.AddMinutes(30), false, userroles);
string HashTicket = FormsAuthentication.Encrypt(Ticket);
HttpCookie UserCookie = new HttpCookie(FormsAuthentication.FormsCookieName, HashTicket);
FormsAuthentication.SetAuthCookie(Login1.UserName,false);
Response.Cookies.Add(UserCookie);
FormsAuthentication.RedirectFromLoginPage(Login1.UserName, true);
Response.Redirect("WebForm1.aspx");
退出:
FormsAuthentication.SignOut();
Session.Abandon();
//这两行很重要,要清除缓存,否则不能退出
Response.Cache.SetExpires(DateTime.Now.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
如何让radiobuttonlist控件和他后面的控件在同一行,不要换行
RepeatDirection="Horizontal" RepeatLayout="Flow"
浮动元素的高度
<div>
<div style="float:left"></div>
</div>
说明:因为有浮动,要想外面的div得到高度,必须清除浮动,如下面代码
<div>
<div style="float:left"></div>
<div style="clear:both"></div>
</div>
