javascript - Change site background colour with colour picker -

-

I am using for my site. I want to change the background of my website body / html , when the selection is in progress as soon as there is a change in the background of the textbox.

I have looked at the JS file but found it a little complicated I have written to the document.body.style.backyle = styleElement.jscStyle.backgroundColor; 410-430 added between lines but nothing changed.

How can I get it?

Thank you

In the demo page you have "Onchange event":

You need to create Input like this: 

  & lt; Input class = "color" onchange = "document.body.style.backgroundColor = '#' + this.color" & gt;   
 My guess is that in your example, you have forgotten before the  #  color hex code.

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'
