javascript - Build an Input value based on other multiple input values -

I have a set of form fields that

  like  type < Text "name =" item "id =" item "value =" "& gt; & gt; input type =" text "name =" desc "id =" desc "value =" "& gt; & lt; input type Input type = "hidden" name = "some code" name = "some code" value = "1" & gt; "text" ; " "Value =" "& gt;    The code that I need is to auto update to the  result  field because in other areas a double code  -  Added between them, the result will look like  
  object - desc - place - somecode - op    for this site i jquery If the other javascript is useful on the site then it is useful (but not required) if it is useful to get the desired result   
 
  It should be assumed that you can add a category to each item. Although I'm not sure if the hidden value changes it will be triggered, do you need it?  
  $ ('input.test'). Change (function () {$ ('# val () ($ (' # item '). Val () + "-" + $ (' # desc '). Val () + "-" + $ (' # Val () + "-" + $ ('# some code'). Val () + "-" + $ ('# op'). Val ());});  < / Pre>

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...
