1.在表单的JS Header中写判断的javascript函数:
var request;
function checkloginname(){
request = new ActiveXObject("Msxml2.XMLHTTP")
if (!request){
request=new ActiveXObject("Microsoft.XMLHTTP");}
request.onreadystatechange=aftercheckloginname;
//这里假设数据库路径为mis/accounts.nsf,且表单中输入帐号的域是account,将这个域的值传递到代理中
url="/mis/accounts.nsf/checkRepeatId?openagent&Id="+document.forms[0].account.value;
request.open("post",url,true);
request.send(null);
}
function aftercheckloginname(){
if (request.readystate==4){
if (request.status==200){
if (request.responseText.indexOf("1")>-1){
alert (" 对不起,该帐号已经被使用!");
document.forms[0].account.value="";
document.forms[0].account.focus();
}
}
}
}
2.新建一个checkRepeatId的代理:
Sub Initialize
Dim ss As New NotesSession
Dim doc,docx As NotesDocument
Dim view As NotesView
Dim db As NotesDatabase
Set doc=ss.DocumentContext
Set db=ss.CurrentDatabase
Set view=db.GetView("checkid") '这个试图即为帐号的试图,试图第一列为帐号
macro=|@RightBack(Query_String_Decoded;"=")| '这句是获取从URL传过来的参数
id=Evaluate(macro,doc)
Set docx=view.GetDocumentByKey(id(0),True)
Print "Content-type: text/xml"
If Not docx Is Nothing Then
Print "1"
Else
Print "0"
End If
End Sub
3.在表单中输入帐号的域,这里举例为account,在域的onchange或者onblur事件中调用javascript方法checkloginname()
