错误: “CheckIsNullOld”未定义
<script type="text/javascript">
//判断浏览器，创建XMLHTTPRequest对象
function CreateXMLHTTPRequest(){
if(window.ActiveXObject){
return new ActiveXObject("Microsoft.XMLHTTP");
}else{
return new XMLHttpRequest();
}
}
//检查旧密码框文本是否为空
function CheckIsNullOld(){
var str=document.getElementById("ctl00_ContentPlaceHolder1_txtOldPassword").value;

//1.创建XMLHTTPRequest对象
var xmlHttpRequest=new XMLHttpRequest();

xmlHttpRequest.onreadystatechange=readyDo;
xmlHttpRequest.open("POST","~manage/AdminModifyHandler.ashx",true);
xmlHttpRequest.setRequestHeader("Content_Type","application/x-www-form-urlencoded");
var data="password="+str;
xmlHttpRequest.send(data);

}
function readyDo(){
if(xmlHttpRequest.readyState==4&&xmlHttpRequest.status==200){
var result=xmlHttpRequest.responseText;
if(result=="true"){
document.getElementById("oldPwd").innerHTML="<img alt='' src='images/duihao.jpg'/>";
}else {
document.getElementById("oldPwd").innerText="密码错误~";
return false;
}
}
}
}


上面是javascript代码


下面是html代码：
<tr>
<td height="30" align="right">
旧密码：
</td>
<td>
<asp:TextBox ID="txtOldPassword" MaxLength="20" onblur="CheckIsNullOld()" TextMode="Password"
runat="server"></asp:TextBox><span id="oldPwd" class="notice">*</span>
</td>
</tr>
<tr>
<td height="30" align="right">
新新密码：
</td>
<td>
<asp:TextBox ID="txtNewPassword" MaxLength="20" TextMode="Password" onblur="CheckIsNullNew()"
runat="server" ValidationGroup="a"></asp:TextBox><span id="newPwd" class="notice">*</span>
</td>
</tr>
<tr>
<td height="30" align="right">
确认新密码：
</td>
<td>
<asp:TextBox ID="txtReNewPassword" MaxLength="20" TextMode="Password" onblur="CheckIsNullReNew()"
runat="server" ValidationGroup="a"></asp:TextBox><span id="ReNewPwd" class="notice">*</span>
<asp:CompareValidator ID="CompareValidator1" runat="server" ControlToCompare="txtNewPassword"

ControlToValidate="txtReNewPassword" ErrorMessage="两次密码不一致！" ValidationGroup="a"></asp:CompareValidator>
</td>
</tr>

下面是一般处理程序
public class AdminModifyHandler : IHttpHandler, IReadOnlySessionState
{

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string pwd = Md5(context.Request["password"]);
if (pwd != null)
{
if (pwd == (context.Session["user"] as T_Manager).pwd)
{
context.Response.Write("true");
}
else
{
context.Response.Write("false");
}
}

}

public bool IsReusable
{
get
{
return false;
}
}

/// <summary>
/// MD5加密
/// </summary>
/// <param name="str"></param>
/// <param name="code"></param>
/// <returns></returns>
public static string Md5(string str)
{

return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5").ToLower().Substring(8, 16);


}


各位朋友 帮看看 为啥鼠标onblur的时候错误: “CheckIsNullOld”未定义啊

[解决办法]

JScript code

 function CheckIsNullOld(){   var str=document.getElementById("ctl00_ContentPlaceHolder1_txtOldPassword").value;   if((str+"")==null||(str+"")==""){   document.getElementById("oldPwd").innerText="不能为空";   return false;   }else {   //1.创建XMLHTTPRequest对象   var xmlHttpRequest=new XMLHttpRequest();   window.function(){   xmlHttpRequest.onreadystatechange=readyDo;   xmlHttpRequest.open("POST","~manage/AdminModifyHandler.ashx",true);   xmlHttpRequest.setRequestHeader("Content_Type","application/x-www-form-urlencoded");   var data="password="+str;   xmlHttpRequest.send(data);       }   function readyDo(){   if(xmlHttpRequest.readyState==4&&xmlHttpRequest.status==200){   var result=xmlHttpRequest.responseText;   if(result=="true"){   document.getElementById("oldPwd").innerHTML="<img alt='' src='images/duihao.jpg'/>";   }else {   document.getElementById("oldPwd").innerText="密码错误~";   return false;   }   }   }    }}
