As an example:
Copy Code code as follows:
<body>
<div id= "One" >
<div id= "Two" >hello</div>
<div id= "three" >
<p>
<a href= "#" >tonsh</a>
</p>
</div>
</div>
$ ("a"). Parent () will get the parental object <p>
$ ("a"). Parents () Get the parent object <p><div.3><div.1>
$ ("a"). Parents (). Filter ("div") will get <div.3><div.1>, and can also be written as $ ("a"). Parents ("div").
If you want to <div.2> objects can be written like this: $ ("a"). Parents ("Div:eq (0)").
What if you click on the <a> link to eject the contents of <div.2>?
Copy Code code as follows:
var id=$ ("a"). Parents ("Div:eq (1)"). Children ("Div:eq (0)"). html ();
alert (ID);
This kind of subscript is easy to get what we want, as long as we don't confuse the order of these subscripts.
