What is the new proper way to use a child selector with a context node in jQuery?

From the jQuery docs:

Note: The $("> elem", context) selector will be deprecated in a future release. Its usage is thus discouraged in lieu of using alternative selectors.

http://api.jquery.com/child-selector/

What would be an alternative selector for this?

回答1:

$(context).children('elem')

also $("> elem", context) is deprecated, but $(context+" >elem") and $("parent>child") are not

回答2:

$('parent').children('childrenelements')

Is my guess :)

But as the other poster said, its only searching directly for childs in a context.

回答3:

For example, if the context is an element, you would use the selector for that element instead of specifying it as context. So instead of:

var main = $('#Main');
var mainDivs = $('> div', main);

you could use:

var mainDivs = $('#Main > div');

I just came across the same issue, I was in the middle of a function and none of the above really helped me. .find seemed to do the trick. This is an example oif how it was useful:

$('selectedcontext').first(function(){
    // perform operations on selectedcontext for ex:
    if($(this).hasClass('someclass')){
        $(this).find('textarea').val();
    }
});
