Jun -
Your main problem appears to be that you are not allowed to do cross-site
scripting. All proper browsers block this since it is a major security hole.
In particular, you cannot specify a domain in the XMLHttpRequest that is
different from the domain of the page running the script. In order to
implement
this restriction with certainty, the browsers generally prohibit the inclusion
of any part of the URL up to and including the domain.
Your example is not complete enough for me to use your example (you put XXXXX),
but in my case I must replace
req.open("GET", "http://www.wisen.us/cgi-bin/Data.pl?deviceid=1234",true);
with
req.open("GET", "/cgi-bin/Data.pl?deviceid=1234",true);
and ensure that my HTML page is located at some variant of
http://www.wisen.us/.../index.html
I hope this helps.
Brian

Subject: not access to webservice from safari
Hi.I'm new.
I want to access to my webservice from Safari on iPad.
My WebService is performed by WCF+OData.
First,I tried from Safari(Ver.5.0.2.) on local PC using
XMLHttpRequest,
but caught the following error at XMLHttpRequst.open() method.
status: Error: INVALID_STATE_ERR: DOM Exception 11
My javascript source is below.
if( window.XMLHttpRequest ){
var xhr = new XMLHttpRequest();
xhr.open( "GET", "http://XXXXXXXX";, true );
xhr.onreadystatechange = function(){
if( xhr.readyState == 4 && xhr.status == 200 ){
alert( xhr.responseText );
}
}
xhr.send( null );
}
I looked into the cause of this error,but I couldn't solve.
Please help me.
regards
