The example in this article describes the usage of filter() function and find() function in jQuery. Share it with everyone for your reference. The specific analysis is as follows:

$("div .cont");
Equivalent to $("div").find(".cont")

The filter() function acts on each object ($(what you get here is what you get)) in the collection,
The find() function searches for subelements matching the expression within each object

Example:

<div class="cont"><p class="cont">asdf</p></div>
<div><p class="cont">jldf</p></div>

Copy after login

Copy code The code is as follows:

$("div").filter(".cont")/ /Get the tag

means finding the div element
with class cont

Copy code The code is as follows:

$("div").find(".cont")//obtained Is the tag

It means that after finding the div, look for elements with class cont in the sub-elements of the div

I hope this article will be helpful to everyone’s jQuery programming.
