Selecting a variable's nested elements - jQuery

Question

I wish to pass a variable to a function and have the function select elements within that variable. I\'m unfamiliar with the syntax of this case however, could any one advise?

Answer 1

Use find if you are searching the Dom.

function doSomething(container) {
  var $element = $(container).find('#element');

  // .. Now do something

}

Use filter if you are wanting to search only the elements contained by container.

function doSomething(container) {
  var $element = $(container).filter('#element');

  // .. Now do something

}
