ASP.NET一些常用的技巧
//如果新闻标题大于某个值就让它后面的省掉
public string shengyue(string str, int Int)
{
if (str.Length <= Int)
{
return str;
}
else
{
str = str.Substring(0,Int) + "...";
return str;
}
}
HTML代码:<%# shengyue(DataBinder.Eval(Container.DataItem,"title").ToString(),13)%>
public string shengyue(string str, int Int)
{
if (str.Length <= Int)
{
return str;
}
else
{
str = str.Substring(0,Int) + "...";
return str;
}
}
HTML代码:<%# shengyue(DataBinder.Eval(Container.DataItem,"title").ToString(),13)%>
//防止刷新重复提交:
Response.Write("<script language='javascript'>alert('信息发表成功!');window.location = '" + Request.Url +"'</script>");
//后台调用前台脚本验证代码
Button1.Attributes.Add("onclick" ,"javascript:data();");
//插入一条数据后立即获取这条ID的值
string strSql_InsertFlow = "insert into data_news(title,body) values('"+title.Trim()+"','"+body.Trim()+"');select @@identity as 'newid'";
//禁止后退按钮
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
