1、jquery搜索框效果
$(document).ready(function() {
//搜索框
$('#keyword').focus(function() {
if($(this).val() == '请输入关键词！') {
$(this).val("");
}
});
$('#keyword').blur(function(){
if($(this).val() == "") {
$(this).val('请输入关键词！');
}
});
});
2、Asp.Net给绑定后的DropDownList加上自定义内容
protected void ddlProvince_SelectedIndexChanged(object sender, EventArgs e)
{
string cityname = this.ddlProvince.SelectedItem.Value;
DataSet ds = Tryine.DBUtility.DbHelperSQL.ExecuteDataSet(CommandType.Text, "select * from Cy_UserInfo where u_city='" + cityname + "'");
if (ds.Tables[0].Rows.Count > 0)
{
this.ddlShopID.DataSource = ds;
this.ddlShopID.DataTextField = "u_companyName";
this.ddlShopID.DataValueField = "userid";
this.ddlShopID.DataBind();
this.ddlShopID.Items.Insert(0, new ListItem("请选择商会", "0"));
}
}
3、ajax和ashx提交数据
$.ajax({
type: "POST", //页面请求的类型，通常使用POST,那么处理页需要使用Request.Form["参数名称"]来获取页面传递的参数
url: "http://www.cnblogs.com/WebService/CgAdd.ashx", //处理页的相对地址
data: { qy: qyname, cg: cgName,cp:cgphone, zx: zxName },
contentType: "application/x-www-form-urlencoded; charset=gb2312",
success: function (msg) { //这是处理后执行的函数，msg是处理页返回的数据
alert(msg);
//提交成功后清空文本框
$("#QyName").val("");
$("#CgName").val("");
$("#Cgphone").val("");
$("#ZxName").val("");
}
});
4、Repeater删除数据
在repeater的某一列放入一个按钮，把按钮的e.CommandName设置为“del”,e.CommandArgument设置你要删除的主键，例如
<td>
<asp:LinkButton ID="lbtnDel" runat="server" CommandArgument='<%#Eval("id")%>' CommandName="del">删除</asp:LinkButton>
</td>
然后再rrepeater的ItemCommand事件里写如下代码
protected void rptEducationalList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "del")
{
//删除的主键=e.CommandArgument.tostring();
//删除的方法;
}
}
5、遍历dataset
DataSet ds = xxx.GetList("");
if(ds == null || ds.Tables.Count <=0 || ds.Tables[0].Rows.Count <= 0)
{
return;
}
//循环遍历ds
foreach(DataRow row in ds.Tables[0].Rows)
{
this.xxx.Text = row["列名"].ToString();
//........
}
6、高光显示关键字
/// <summary>
/// 高光显示关键字
/// </summary>
/// <param name="PageStr">内容</param>
/// <param name="keys">关键字</param>
/// <returns></returns>
public string p__HighLight(string PageStr, string keys)
{
string[] key = keys.Split(new string[] { " " }, StringSplitOptions.None);
for (int i = 0; i < key.Length; i++)
{
PageStr = PageStr.Replace(key[i].Trim(), "<font color=#C60A00>" + key[i].Trim() + "</font>");
}
return PageStr;
}
/// <summary>
/// 替换关键字为红色
/// </summary>
/// <param name="pain">原始内容</param>
/// <param name="keyword">关键字，支持多关键字</param>
public string HighLightKeyWord(string pain, string keys)
{
string _pain = pain;
string[] key = keys.Split(new string[] { " " }, StringSplitOptions.None);
if (key.Length < 1)
return _pain;
for (int i = 0; i < key.Length; i++)
{
System.Text.RegularExpressions.MatchCollection m = System.Text.RegularExpressions.Regex.Matches(_pain, key[i].Trim(), System.Text.RegularExpressions.RegexOptions.IgnoreCase);
//忽略大小写搜索字符串中的关键字
for (int j = 0; j < m.Count; j++)//循环在匹配的子串前后插东东
{
//j×31为插入html标签使pain字符串增加的长度:
_pain = _pain.Insert((m[j].Index + key[i].Trim().Length + j * 31), "</span>");//关键字后插入html标签
_pain = _pain.Insert((m[j].Index + j * 31), "<span style=color:red>");//关键字前插入html标签
}
}
return _pain;
}
7、获得Model修改数据
protected void btnCancel_Click(object sender, EventArgs e)
{
string recordNO = Request.QueryString["recordNO"];
rRecord = bllRR.GetModel(recordNO);//获得一个model
rRecord.Status = "已取消";
if (bllRR.Update(rRecord))
{
AddLog.Add("车辆维修记录", "取消车辆维修：" + recordNO, Convert.ToInt32(Session["organid"].ToString()));
MsgUtil.CreateInstance().ScriptAlert(this, "取消维修成功!", "/Organ/index.aspx", Icons.success);
}
else
{
MsgUtil.CreateInstance().ScriptAlert(this, "取消维修失败!", Icons.alert);
}
}
8、发送邮件
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Mail;
namespace Tryine.Common
{
public class EmailClass
{
/// <summary>
/// 发送邮件
/// </summary>
/// <param name="to">收件人邮件地址</param>
/// <param name="from">发件人邮件地址</param>
/// <param name="subject">邮件主题</param>
/// <param name="body">邮件内容</param>
/// <param name="username">登录smtp主机时用到的用户名,注意是邮件地址'@'以前的部分</param>
/// <param name="password">登录smtp主机时用到的用户密码</param>
/// <param name="smtpHost">发送邮件用到的smtp主机</param>
public void Send(string tos, string froms, string subject, string body, string userName, string password, string smtpHost)
{
MailAddress from = new MailAddress(froms);
MailAddress to = new MailAddress(tos);
MailMessage message = new MailMessage(from, to);
message.Subject = subject;//设置邮件主题
message.IsBodyHtml = true;//设置邮件正文为html格式
message.Body = body;//设置邮件内容
SmtpClient client = new SmtpClient(smtpHost);
//设置发送邮件身份验证方式
//注意如果发件人地址是abc@def.com，则用户名是abc而不是abc@def.com
client.Credentials = new NetworkCredential(userName, password);
client.Send(message);
}
}
}
9、搜索框效果
/* 搜索文本框效果 */
$(function () {
$("#searchkey").focus(function () {
$(this).addClass("focus");
if ($(this).val() == this.defaultValue) {
$(this).val("");
}
}).blur(function () {
$(this).removeClass("focus");
if ($(this).val() == '') {
$(this).val(this.defaultValue);
}
})
})
10、指定下拉列表的选定项
string pid = ds.Tables[0].Rows[0]["parentID"].ToString();
if (pid != "0")
{
this.ddl_P.Items.FindByValue(pid).Selected = true;
}
