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?
For example, when a button is clicked within a container I wish for that container to be stored in a variable, okay I have that part. But then I wish to select a certain element within that container like
$(container "div#element");
How can you combine the two, noting that these elements could be deeply nested?
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.
For chainability you can also use:
$(container).find('#element');
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
}
