jQuery find $.find('selector') versus $('selector') difference

Question

I\'ve got a question why these two code snippets are different.

$(\'#ctl00_DDMenu1_HyperLink1\')  
//jQuery(a#ctl00_DDMenu1_HyperLink1 Default.aspx) Console          


        

Answer 1

The reason this does not work is because find() lets you filter on a set of elements based on a selection you've already made.For example if you wanted to select all of the inputs within a particular form, you could write:

$('#aParticularForm').find('input') 

It cannot be called on its own.
