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

For chainability you can also use:

$(container).find('#element');

Answer 2

jQuery gets a second parameter, which determines the scope of the selection. For example $('#first-name', '#registration-form') only matches elements with the first-name id inside registration-form.

I guess you can use this feature. I think $("div#element", container); would work.

See this fiddle.

Answer 3

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

}
