So all in one line   var checkedItemsAsString       id   checkbox   checked   map function     return   this  val   toString        get   join           a note about the selector  id   checkbox     it will grab any item with the string  checkbox  in it   A bit clumsy here  but really good if you are trying to pull the selected values out of something like a  NET CheckBoxList   In that case  checkbox  would be the name that you gave the CheckBoxList control

A bit more modern way to do it  const selectedValues      input name  quot locationthemes quot   checked   map  function               return   this  val                 get        join         We first find all the selected checkboxes with the given name  and then jQuery s map   iterates through each of them  calling the callback on it to get the value  and returning the result as a new jQuery collection that now holds the checkbox values  We then call get   on it to get an array of values  and then join   to concatenate them into a single string - which is then assigned to the constant selectedValues

Map the array is the quickest and cleanest      var array     map    input name  locationthemes   checked    function c  return c value       will return values as an array like   array   gt   2 3    assuming castle and barn were checked and the others were not

In jQuery just use an attribute selector like     input name  locationthemes   checked      to select all checked inputs with name  locationthemes   console log    input name  locationthemes   checked   serialize        or     input name  locationthemes   checked   each function        console log this value            Demo      In VanillaJS      forEach call document querySelectorAll  input name  locationthemes   checked    function cb       console log cb value             Demo     In ES6 spread operator      document querySelectorAll  input name  locationthemes   checked        forEach  cb    gt  console log cb value         Demo
