remove element from html list using jquery?

Question

This is my jquery source

And this is my html source.

The add element in list works but remove doesn't work.

However, when I remove the parameter from .remove() it removes the element, but I will have more than one ul list in a page. I need to specify ul list

Answer 1

Your selector is incorrect. Use

 $('ul#family_list li:last').remove();

or

 $('ul#family_list').remove('li:last')

You should also read docs properly

Answer 2

Your selector to remove is backwards. It should be

$('ul#family_list li:last').remove()

Also, in future, please post your code in code tags, rather than posting an image of it

Answer 3

试试这个： $('ul#family_list li:last').remove()
