Multiple selector chaining in jQuery

Question

Normally when I use a class as a selector I try to use an  id  selector with it so it does not search through the entire page but only an area where the class would be   However I have a partial view with code in it  This partial view  common code  gets wrapped around a form tag   I have    lt form id  Create  gt     load common code in from partial view  lt  form gt    lt form id  Edit  gt     load common code in from partial view  lt  form gt    Now in this common code I need to attach a plugin to multiple fields so I would do      Create  myClass   plugin   options here         Edit  myClass   plugin  options here      So it s pretty much the same code  I am wondering if there is a way to make it look for either of the id s   Edit  I am having problems with it when I have variables for my selectors      my selectors                  A    Create           B    Edit           Plugin     Plugin              selector A  selectors Plugin  selector B  selectors Plugin    Does not seem to run

like       Create  myClass   Edit  myClass   plugin        options  here          You can specify any number of   selectors to combine into a single   result  This multiple expression   combinator is an efficient way to   select disparate elements  The order   of the DOM elements in the returned   jQuery object may not be identical  as   they will be in document order  An   alternative to this combinator is the    add   method     Multiple Selector Add method

If we want to apply the same functionality and features to more than one selectors then we use multiple selector options  I think we can say this feature is used like reusability  write a jquery function and just add multiple selectors in which we want the same features   Kindly take a look in below example    x000D   x000D      div  span   paragraph   paraId    css    font-family    tahoma    background    red      x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt  x000D   lt div gt Div element lt  div gt  x000D   lt p class  paragraph  gt Paragraph with class selector lt  p gt  x000D   lt p id  paraId  gt Paragraph with id selector lt  p gt  x000D   lt span gt Span element lt  span gt  x000D   x000D   x000D    I hope it will help you  Namaste

You can combine multiple selectors with a comma       Create  myClass  Edit  myClass   plugin  options here      Or if you re going to have a bunch of them  you could add a class to all your form elements and then search within that class   This doesn t get you the supposed speed savings of restricting the search  but I honestly wouldn t worry too much about that if I were you   Browsers do a lot of fancy things to optimize common operations behind your back -- the simple class selector might be faster

There are already very good answers here  but in some other cases  not this in particular  using map could be the  only  solution    Specially when we want to use regexps  other than the standard ones   For this case it would look like this        myClass   filter function index  elem        var jElem     elem        return jElem closest   Create   length  gt  0                jElem closest   Edit   length  gt  0      plugin         As I said before  here this solution could be useless  but for further problems  is a very good option
