javascript - iframe dynamic height doesn't work -

-

I have created a small widget that is basically a php file that contains an HTML AJAX based form. The height of the form depends on the production of AJAX reaction text. Therefore, I need to change the speed dynamically. I tried to do this with some code and it actually works well, but only on the local host file. This code works: 

  & lt; Iframe src = "ajax / cfw.php" id = "idIframe" width = "400px" onload = "iframe loaded ()" style = "border: none;" & gt; & Lt; / Iframe & gt; & Lt; Script type = "text / javascript" & gt; Function iframeLoaded () {var iFrameID = document.getElementById ('idIframe'); If (IFFROMId) // Here you can make the height, then I delete it first, then make it again the IFrameID. Hect = ""; IFrameID.height = IFrame Iocentent Window.document.body.scrollHeight + "px"; }} & Lt; / Script & gt;

However, when I try to IFrame the exact file I pointed out at my local host which does not host on my localhost, then it does not work: 

  & lt; Iframe src = "http://website.com/ajax/cfw.php" id = "idIframe" width = "400px" onload = "iframe loaded ()" style = "border: none;" & Gt; & Lt; / Iframe & gt;

Why is it, and how can I fix it? Thank you.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
