javascript - find an element by style with jquery -

-

How can I get an element in an HTML document, whose style is the property? Here's an example:

HTML: 

  & lt; Ul & gt; & Lt; Li style = 'z-index = 1;' & Gt; E1 & lt; / Li & gt; & Lt; Div style = 'z-index = 8;' & Gt; Div & lt; / Div & gt; & Lt; Li style = 'z-index = 2;' & Gt; E2 & lt; / Li & gt; & Lt; Li style = 'z-index = 3;' & Gt; E3 & lt; / Li & gt; & Lt; Li style = 'z-index = 4;' & Gt; E4 & lt; / Li & gt; & Lt; Li style = 'z-index = 5;' & Gt; E5 & lt; / Li & gt; & Lt; Ul & gt;   
 The question is how do I choose, for example:   
  •    z-index = 4 . And how to select all with  div  to  z-index = 8  ...   
     
     
     If the style is set to inline, you can use an attribute selector:  
      $ ('li' [style * =" z-index : 4 "] ') // z-index = 4   
    . The advantage of this method is that it is very fast.  
     If the style is set through the stylesheet, then you can access it like this:  
      var elem; Var elems = $ ("li"); For (var i = 0; i & lt; elems.length; i ++) {if ($ (elems [i]). CSS ('z-index') == '4') {elem = elems [ I]; // Assignment we found to be inattentive; // exit loop start}}   
      note  webkit browser, (safari, chrome, etc.), unless this situation is in the z-index The neck will not return the well. See it  
     In addition to this, there is still to loop. Filter ()

    -
    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'
