javascript - How can I select certain HTML-Element in div - Stack Overflow

admin2025-04-21  1

I want to select certain HTML elements in a DIV. Something like this:

$("#foo table,tr,td,span,p" ).addClass( Myclass );

But it adds the class also outside of DIV "#foo". I.e. only the elements in div "#foo" are the class "Myclass" to add. Thanks.

  • 1 Because your selectors after the ma are generic, you need to specify #foo before each elem – tymeJV Commented Oct 21, 2014 at 21:33

Problem: Comma , separates autonomous selectors. You have to select #foo first, then select your inner elements table, tr, td, span, p.

You can use context attribute:

$("table, tr, td, span, p", "#foo").addClass("Myclass");

or you can chain your selectors:

$("#foo").find("table, tr, td, span, p").addClass("Myclass");

You need to do it this way, each element has to have the parent id, i.e. #foo, before it and you need to wrap your class-name, i.e. myClass, with "".

$("#foo table, #foo tr, #foo td, #foo span, #foo p").addClass("Myclass");

When you add a ma, you are separating you selectors. Try

$("#foo table, #foo tr, #foo td, #foo span, #foo p" ).addClass( Myclass );

Are you intending to select the tables, tr, td, spans, and p within div with ID foo? That selector would be more like

$("#foo table,#foo tr, #foo td, #foo span, #foo p")

Your current selector is saying "all tables inside div with ID "foo" and then also all tr, td, spans, and p on the whole document

You have two ways of doing it:

Method 1:

$("#foo").find("table, tr, td, span, p").addClass("Myclass");

Method 2:

$("#foo table , #foo tr, #foo td, #foo span, #foo p").addClass("Myclass");
