scope - Javascript array.length is 0 until I do an alert() -

I am trying to write some javascript that creates HTML controls based on feedback from a SharePoint WebServices getList. I store the control in an array after the creation of the array, until it does not execute a warning, then it becomes the correct number.

  var controls = []; Call the webserver ($ {Operation: "GetList", list name: qs ["list"], fullfunk: parselists to retrieve $ [document] .ready (function () {// list data $ ()). }; Console .log (controls.length); // This output 0 warnings ("It is here to work."); // it should be here; why not console.log (controls.length); // for output 6 (var i = 0; i & lt; controls.length; i ++) {control [i] .addControl ();}}); Function Parslink (ExData, Status) {$ (xData.responseXML) .Find ("Field"). Each (function () {if ($ (this) .attr ("ID") & $ (this) Attr ("SourceID") = "http://schemas.microsoft.com/sharepoint/v3") { If ($ (this) .attr ("type") == "text") {controls.push (new textbox (it));} and if ($ (this) .attr ("type") == "option "& Amp; amp; $ (this) .attr (" format ") ==" dropdown ") {control push (new dropdown (this)); and if ($ (this) .attr (" type ") == "Option" & amp; $ (this) .attr ("Format") == "Radiobutton") {Control.push (New Radiobutton (this)); and if ($ (this) .attr ("Type" ) == "multichoice") {controls.push (new multi-option (this));} and if ($ (this) .attr ("type") == "Boolean") {controls.push (new boolean (this));}}}); }    Alert is the only thing that works with  controls.length . I can only think that this is some type of problem. No insights is appreciated.   
 
  This is probably due to this asynchronous code  
  $ () . SPServices ({Operation: "GetList", list name: qs ["list"], fullproduct parselists});    Warning prevents thread execution temporarily for allow callback function  
 Then try to move this part  
  console.log (controls.length); // for output 6 (var I = 0; i & lt; controls.length; i ++) {control [i] .addControl (); }  parseList ()  function    in

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.
