jquery - How to target all children, not just first level? -

this target first level children:

$(this).children() 

how can target children not first level, childrens children , on?

from jquery docs:

unlike of tree traversal methods, selector expression required in call .find(). if need retrieve of descendant elements, can pass in universal selector '*' accomplish this.

you need add selector within .find() (unlike .children()), add asterisk.

hence, $(this).find('*');
