syntax - Why do I see javascript arrays getting created with string.split()? -

I see such code across the web

  var days = "Monday Tuesdays Wednesday Thursday Friday Saturday Sunday ".split (" ");

Why do so

  var days = ["Monday", "Tuesday", "Wednesday", "Thursday", instead of "Friday" , "Saturday Sunday"];

I do not think there is nothing with idleness or ignorance. This jQuery is out of 1.4.2

  Sahara: "altKey attrChange attrName bubbles button cancelable charCode clientX clientY ctrlKey currentTarget data descriptioned event element handler key codecod layerx learer meta newoffice offset x offset y original Goal Page X Page Y PARWorldX Related Noida Related Goal ScreenX Skinny Shift's Element Goal for White Element View Wheel Delta ".split (" ")

do it everywhere Areas are.

I think this is because you do not have to quote each string in the array and separate it . Similarly, in Perl, many people qw (abcdefg) ('a', 'b', 'c', 'd', 'e', 'f' , 'G') . Therefore the profit is two times:

   Fast and easy to write and modify (can be clearly debated) 
  It's small, so you remove some bandwidth. 
 
  View bit size: 
   var days = "Monday Tuesday Wednesday Thursday Friday Saturday Sunday" .split (""); // 81 characters  
  versus 
   var days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday Sunday"]; // 91 characters

Unable to get a fresh ASP.NET MVC project running with Visual Studio
2008 -



    This is a very basic question. I'm asking this silly about this, but I'm stuck something else and hopefully That something here can save me some time. So I open VS2008, to download the new ASP.NET MVC web application and click OK I want to prepare a test project. I debug my new MVC project to hit F5 then I enable the debugging to the web. I choose to modify the config file. It goes where I get a page load error.   Firefox can not establish a connection to the server on the local host: 57323.   Do I have to do something special for Vista? Or I should do something with IIS   Thanks for helping a noob   6/30/2009 update   OK, I think that I VS2008 may need to be reinstalled with the ASP.NET Development Server port. I have tried to do everything that I have suggested. I've marked Default.aspx as the start page. I tried to open it in Firefox / IE 8 / and Chrome. I tried to uninstall / reinstall ASP.NET MVC, which was not working. I tried telnetting with Putin with a local ho...






delphi - Mouseover hint for TChart series value -



    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query:    chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End;    Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar.   Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...?      This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you:    Process TForm...






sql - Incorrect syntax near the keyword 'table' -



    I'm getting this error what I'm doing is trying to get data from a table and a db and Keep it in another DB and table. The tables are not exactly the same, I am using a FETCH cursor, so I get the first line from the DB1 table and then keep each column value in the declared variable. Then I run an assembly statement in db2 table and get the next value. All of these are working properly because it runs properly, but in the end I get this error,   Wrong syntax near the keyword 'table'.   In the entire transaction details, an attempt / catch with the error of expression in the Cat block, apart from this, I do not know what is the reason for it.   Here is the code    added to prevent additional result set at SET NOCOUNT - Interfering with the SELECT statement.
