Javascript iframe without src with nested scripts -


is possible create iframe scripts in head element, before iframe being inserted dom , have scripts onload="alert(1)" fire when ready?

example 1, using nested scripts:

var iframe  = jquery("<iframe></iframe>"); var scripts =  '' +             '<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"          onload="alert(1);"><\/script>' +             '<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/chrome-frame/1.0.3/cfinstall.min.js" onload="alert(2);"><\/script>';  iframe.html(scripts);  jquery("body").append(iframe);

example two, bigger:

function loadscript(path, callback, appendto) {         var element = document.createelement('script');         element.setattribute ("type", 'text/javascript');         element.setattribute ("src", path);          return loadelement(element, callback, appendto); }  function loadelement(element, callback, appendto) {         element.loaded = false;          if (element.readystate){  // ie                 element.onreadystatechange = function(){                         if (element.readystate == "loaded" || element.readystate == "complete"){                                 element.onreadystatechange = null;                                  loadelementonload(element, callback);                         }                 };         } else {                 // others                 element.onload = function() {                         loadelementonload(element, callback);                 };         }          (appendto).appendchild(element);          return element; }  function loadelementonload(element, callback) {         if (element.loaded != true) {                 element.loaded = true;                 if ( callback ) callback(element);         } }   function loadscriptnew1(src, callback, appendto) {         loadscript(src, callback, appendto) }  var iframe  = jquery("<iframe></iframe>");  loadscriptnew1("http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js", function() {         alert(11) }, iframe.get(0) )   loadscriptnew1("http://ajax.googleapis.com/ajax/libs/chrome-frame/1.0.3/cfinstall.min.js", function() {         alert(22) }, iframe.get(0) )  jquery("body").append(iframe)

none of these ways trigger onload functions' alert;

is possible? scripts gets loaded in both cases, window objects set, no callback.

try this:

<html> <head>  <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>  <script type="text/javascript">   function insertiframe() {   var iframe = $('<iframe></iframe>').appendto('body')[0];    // switch straight js   var script = iframe.contentwindow.document.createelement("script");   script.type = "text/javascript";   script.src = "//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js";   script.onload = function() { alert(1); };   iframe.contentwindow.document.body.appendchild(script);  }  </script> </head> <body onload="insertiframe()"> </body>

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
