通过Ajax发布Base64图像数据-数据截断

Question

I am attempting to send Base64 image data via ajax to Server. Sometimes all the pics make it, other times only aa few make it.

Any ideas for error checking that all the data is received by the server?

http.open("post", URL, true);

http.onreadystatechange =   function()
{ 
     if(http.readyState  == 4)
     {
          if(http.status  == 200) {
              alert(http.responseText);
          alert("eReport Successfully sent to Server " + CustID +" "+name +" "+ListType);
          //clearCurrentReport();
          removeReport(CustID, ListType);
          } 


           //   alert("Received:"  + http.responseText); 
          else 
             alert("Report NOT SENT. Error Communicating with Server.  Please try again when you have a connection." );
     }
}; 

params = custid="+CustID+"&photo1="+pic1+"&photo2="+pic2+"&photo3="+pic3+"&photo4="+pic4+"&photo5="+pic5+"&photo6="+pic6;

http.send(params);

A possible problem is the amount of data you are sending. The server has a limit for the data, that can be sent at once. And php ( if you are using php ) has such a limit.
