ruby on rails - Selecting active option in jQuery Mobile -

-

The mobile page for my app is the header with the menu menu select the jQuery Mobile dropdown. 

  & lt; Span data-role = "fieldcontain" id = "category-dropdown" & gt; & Lt; Select name = "selection-country-2" id = "selection-country-2" data-mini = "true" & gt; & Lt; Option value = "& lt;% = root_path%>" & Gt; Home & lt; / Options & gt; & Lt; Option value = "& lt;% = newest_path%>" & Gt; New & lt; / Options & gt; & Lt; Option value = "& lt;% = group_path (group.fund (1))% & gt;" & Gt; Group 1 & lt; / Options & gt; & Lt; Option value = "& lt;% = group_path (group.fund (2))%>" & Gt; Group 2 & lt; / Options & gt; & Lt; Option value = "& lt;% = group_path (group.fund (3))% & gt;" & Gt; Group 3 & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Span & gt;   
 I am using JavaScript below to navigate to the selected page.  
  & lt; Script type = "text / javascript" & gt; $ (Document) .ready (function () {$ ("# select-native-2"). Change (function () {if ($ (this) .val ()! = '') {Window.location.href = $ (This) .val ();}})}}; & Lt; / Script & gt;   
 My problem is, when a user redirects to another page, the first option ("home") is selected back menu. How can I select the current page reflect the current page?  
 My guess is that I need to have the # 1 symbol  
  option which is "active,"   
  # 2 Make sure Javascript is enabled on selectmenu .  
 What is the best way to do those two things?  
 I can do the  # 1  below, but it is quite ugly  
    
  For # 2,  I'm not sure what is the best way to select it.  
 Appreciate your input! Why not use the <<> selected selected  attribute?  
 
  
 
 & lt; Span data-role = "fieldcontain" id = "category-dropdown" & gt; & Lt; Select name = "selection-country-2" id = "selection-country-2" data-mini = "true" & gt; & Lt; Option value = "& lt;% = root_path%>" & Gt; Home & lt; / Options & gt; & Lt; Option value = "& lt;% = newest_path%>" & Gt; New & lt; / Options & gt; & Lt; Option selected value = "& lt;% = group_path (group.fund (1))% & gt;" & Gt; Group 1 & lt; / Options & gt; & Lt; Option value = "& lt;% = group_path (group.fund (2))%>" & Gt; Group 2 & lt; / Options & gt; & Lt; Option value = "& lt;% = group_path (group.fund (3))% & gt;" & Gt; Group 3 & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Span & gt;   
 This will make the selected option "Group 1" on the page load. You have to find out which options will get this feature. But it should be easy to do so by Ruby.

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). 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'
