javascript - inserting a row on click jquery -

-

I am struggling to explain why my code is not working, I have a text field, 2 checkboxes and One row has an add button. I have 4 rows on the load, I have a hyperlink when clicked, should add a new row at the end of the table Adding my code line Alternatively the first row starts with my last row 4 which is the cloning I am doing I'm getting the sequence when clicking on the link 1,4,2,4,3,4,4,4

I do not know where I'm making a mistake, I banging my head I've been in the last 4-5 hours for 

  & lt; Table id = "setting" & gt; & Lt; Tr & gt; & Lt; Td> & Lt; Input name = "name_1" type = "article" /> gt; & Lt; / Td> & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "button" /> & Lt; / Td> & Lt; / Tr & gt; & Lt; Tr & gt; & Lt; Td> & Lt; Input name = "name2" type = "text" /> gt; & Lt; / Td> & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "button" /> & Lt; / Td> & Lt; / Tr & gt; & Lt; Tr & gt; & Lt; Td> & Lt; Input name = "name_3" type = "text" /> gt; & Lt; / Td> & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "button" /> & Lt; / Td> & Lt; / Tr & gt; & Lt; Tr & gt; & Lt; Td> & Lt; Input name = "name_4" type = "text" /> gt; & Lt; / Td> & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "checkbox" /> & Lt; / TD & gt; & Lt; Td> & Lt; Input type = "button" /> & Lt; / Td> & Lt; / Tr & gt; & Lt; / Table & gt; $ ('# Add'). ("Click", function (e) {e.preventDefault (); e.stopPropagation (); $ clone = $ ('# settings tbr'). Filter (": last") .clone (true) .inertAfter ('# Settings ttr'). Filter (": last"). Val ('');   
 I did not work for one of the following, I do not know That's why  
  $ ('# settings tbody tr: last'). Clone (true) .inertAfter ('Val (' ');    
 
 
 You have  Tbody is not , but you can get it in jQuery Using:  
  & lt; table Id = "setting" & gt; // & lt; ------------------ ----- disappear here & lt; tr & gt; & lt; td & gt; & lt; input name = "name_1" type = "text" /> gt; & lt; / td & gt; ... .............. $ ('# & lt; Portlet: Namespace / & gt; Settings TD tr: Last') // ------------- ------------- ^^^^^ ------------ It is not   
 Instead you try it Can:  
  $ ('# & lt; Portlet: namespace / & gt; Settings tr: last ')   
 
 Update:  
  $ (' # settings TDR ') // ------- - ^ ----------------- It messes up   
 wrong ID selected use  settings  instead < Code> Settings :  
  $ ('# setting tr: last-child'). Clone () InsertAfter ('#settings tr: last'); Another update:  
  $ ('# add')) (function (e) {var $ cln $ Cln.find (': text') Attr ('id', 'textbox' + $ ('#settings tr: last-child') = $ ('#transfer tr: last-child'). ('' Checkbox ''). Each (function (i, v) {$ (this) .attr ('id', 'check' + $ ('ft (' id ',' btn '+ 1). $ ('# Setting tr: last-child'). $ Cln.insertAfter ('#settings tr: last'); console.log ($ cln.find (': text'). Attr ('id '' + '& Lt; === & gt;' + $ cln.find (': checkbox: eq (0)'). Attr ('id') + '& lt; === & gt;' + $ Cln address (': checkbox: eq (1)'). Attr ('id'));});

excel vba - How to delete Solver(SOLVER.XLAM) 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'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
