How can an event handler register the loaded elements in the DOM?

Just test them for first existence:

  var signup, Signin, bookmark; If (signup = document.getElementById ('signup')) signup.onclick = interface_signup; ...    etc.

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!

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...
