javascript - How to get a count back for my json? -

I have a response from my server that looks like this

  { "Errors": "{{ViewModels [0]": "Not a valid number."}, "IsValid": wrong, "successful message": null}    Looping through is worried about errors (in this case there is only one, but many people are).  
 I tried  
  function texture (response) {for (var i = 0; i & lt; response.Errors.length; i ++) {var error = Reaction. Astrar [i]; Warning (error); }}    The length is temporarily undefined though. So I'm not sure what I'm doing.   
 
  for  var error errors in response (warning (error. Errors [error] ); }    If you are crazy about the prototype on the object object, you may also want to include the EvenOnProperty.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
