javascript - jQuery Validation conditional dependency: ensure text input matches value if radio button checked -

-

I have some form elements that adhere to this type of format: 

  & Lt; Input type = "radio" name = "test" value = "a" & gt; & Lt; Input type = "text" size = "3" name = "weight A" id = "A" & gt; & Lt; Br> & Lt; Input type = "radio" name = "test" value = "b" & gt; & Lt; Input type = "text" size = "3" name = "weight-B" id = "b" & gt; & Lt; Br>   
 I am using jQuery validation plugin to perform client-side validation. What I would like to do with these areas, to ensure that the text input corresponding to the selected radio button is equal to 100. I have implemented it successfully on server-side using PHP, but would like to add a JS method to give immediate feedback. Before I submit the form, I already have a jmt  range:  rule in numeric range [1-100] Within two text areas included to limit user input.  
 How do I do this work? Can  jQuery.validator.addMethod  be the way to do this?  
  Edit:  In response to the comments of the participant, I have tried an addMethod: Val () === "" "" "" ""; Var selB = $ ('[name = "test"]'). Val () === "B"; if (sella and company ($ ("#a") .val ()! = = "100" )) {Return false;} and if (selB & amp; amp; amp; ($ ("($" ("#b"). Val ()! == "100")) {return false;} And back to true;}, "the selected option should be equal to 100.");   
 It starts triggering verification for  # a  but  Not   #b , and display error message  Message:  is specified by the rule, which is specified by  addMethod . Please note that I have a minimum programming background.   < P> 
 
 Try it out:  
  Demo:   
  $ Validator.addMethod ("selectWt", function (value, element) {if ($ (element) .prev (). (': Check')) {return ($ (element) .val () === 100 );} And {return true;}}, "the selected option will be equal to 100.");   
 This rule can be implemented normally, it only checks to see if the previous radio element of the element is  checked  if yes , Then it returns  true , if the value of the text element is  100 .  
 The way it is written, it only works when your  type = text  element immediately follows the  type = radio  element if If you change the HTML system, then it will need to be tweaked.  
 
 This can be made as a parameter by passing in the  100  value to be more flexible.  
 Demo:  
  $ Validator.addMethod ("selectWt", function (value, element, absolute) {if ($ (element) .prev (). (': Check')) {return ($ (element) .val () === Ultimate );} And {return true;}}, "selected option equals {0}."); Validate   
 ...   $ ('# myform') (Start the {// plugin rule: {myfield: {selectWt: 100 / Use a parameter instead of "true"}}}});

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 have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? 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. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from.
