javascript - How to change the font size using execCommand -

My HTML file has a style for fonts I FONT {font-size: 11px; } which will load initially when my html is loaded, I would like to change the font-size using the following command document.execCommand ("fontsize", "", "5"); After the execution, now the font tag has the attribute size = "5" but I can also see the font-size: 11px still in the current style of IE Developer Toolbars. Then the font is not changed.

Please help to change the font size it may be late, but I am trying to confirm that document.exec comand ('font size, false,' 5 '). In some browsers, false is not going through the default UI (second argument), the result is not running in the command.

What does it return when you run it? execCommand will return true / false on the basis of success or failure.

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...
