Using jquery to get all checked checkboxes with a certain class name

Question

I know I can get all checked checkboxes on a page using this      input type checkbox    each function          var sThisVal    this checked     this  val                But I am now using this on a page that has some other checkboxes that I don t want to include   How would I change the above code to only look at checked checkboxes that have a certain class on them

input checkbox class   each function             var sThisVal    this checked     this  val                  An example to demonstrate     checkbox is a selector for checkboxes  in fact  you could omit the input part of the selector  although I found niche cases where you would get strange results doing this in earlier versions of the library  I m sure they are fixed in later versions    class is the selector for element class attribute containing class

input yourClass checkbox checked   each function          var sThisVal     this  val          This would get all checkboxes of the class name  yourClass    I like this example since it uses the jQuery selector checked instead of doing a conditional check   Personally I would also use an array to store the value  then use them as needed  like   var arr          input yourClass checkbox checked   each function          arr push   this  val

I m not sure if it helps for your particular case  and I m not sure if in your case  the checkboxes you want to include only are all part of a single form or div or table  but you can always select all checkboxes inside a specific element  For example    lt ul id  selective  gt    lt li gt  lt input type  checkbox  value         gt  lt  li gt    lt li gt  lt input type  checkbox  value         gt  lt  li gt    lt li gt  lt input type  checkbox  value         gt  lt  li gt    lt li gt  lt input type  checkbox  value         gt  lt  li gt   lt  ul gt    Then  using the following jQuery  it ONLY goes through the checkboxes within that UL with id  selective        selective input checkbox   each function       var sThisVal    this checked     this  val
