An array as jQuery context argument

[silesianlordt]

I think it should be possible to pass an array of DOM elements to jQuery() as context.

Example:

HTML:

<div id="a">
  <span class="book">
</div>
<div id="b">
  ... some html...
</div>
<div id="c">
  <span class="book">
</div>
<div id="d">
  ... some html...
</div>

JS:

var a = $('#a'),
    c = $('#c');

$('.book',[a,b]).hide();

I know there are different ways to do what I've done above. I want to show simple example.

Sorry should be:

$('.book',[a,c]).hide();

not

$('.book',[a,b]).hide();

Isn't that the same as... $(".book").hide();

In recent discussions, the team has been resistant to add additional signatures to the main jQuery() function. In general, the context argument is just a long-path to $(context).find("selector"), so adding additional type checking into the main jQuery function to test for an array of dom elements as CONTEXT, when an array of DOM elements is already an existing signature and you could simply do $([a,b]).find(".foo");

Also worth noting is that your example does not actually use an array of DOM elements as the context, it tries to use an array of jQuery objects as the context, which I tend to think we're even less inclined to support - as either the first or second argument to jQuery - see #9011
