How to check if UL has li? ›

Each of the list elements of the unordered list is first selected using a jQuery selector. The each() method is used on this list to iterate through it.

The <li> HTML element is used to represent an item in a list. It must be contained in a parent element: an ordered list ( <ol> ), an unordered list ( <ul> ), or a menu ( <menu> ).

The <ul> and <ol> elements may be nested as deeply as desired. Moreover, the nested lists may alternate between <ol> and <ul> without restriction.

Definition and Usage

The <li> tag is used inside ordered lists(<ol>), unordered lists (<ul>), and in menu lists (<menu>). In <ul> and <menu>, the list items will usually be displayed with bullet points. In <ol>, the list items will usually be displayed with numbers or letters. Tip: Use CSS to style lists.

According to the HTML specification, the only valid direct children of a <ul> element are <li> elements. The <li> element represents a list item within an unordered list ( <ul> ) or an ordered list ( <ol> ).

The li element has an end tag ( </li> ), but it's optional in some cases: An li element's end tag may be omitted if the li element is immediately followed by another li element or if there is no more content in the parent element. </li> is not optional for XHTML compliance.
