Hide all li tags with jquery

Question

Please help me to complete my code. I want to hide all <li> tags on body onload.

$(document).ready(function () {
$('li > ul').hide();    
});

Please give me the right variant for the code!

Answer 1

是ul > li ，不是li > ul

$(document).ready(function () { $('ul > li').hide(); });

Answer 2

$(function(){
  $('li').hide()
})

This will search and hide every <li> tag on the page. It is better to narrow down the search to improve performance Ex: $('#mydiv li') where mydiv is the id of the ul tag <ul id="mydiv"> .
