javascript - how do you get the integer value of a field? -

-

I had to use it to get an integer value of the field: 

  var local = {}; Local.result = $ ('# myID'). Val (); Local.result = parseInt (0+ local.result); Local Return   
 Question: Is it a best practice instead, like some kind of jQuery method that gives value or number 0 if it is not a value?  
 Let me more jQuery!   
 
 
 You should only make any strong efforts to use  + val  If you have a non-numeric value, and want to default to 0 on your original post like this:  
 str  >  var num = + str || 0; JSFiddle:

 I'm not sure that you mean any float conversion. It seems that this is already an integer because otherwise you will not be able to do it on  parseInt , okay?

Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
