// when dom is loaded
$(document).ready(function(){
    // on somebody clicks a button element
    $("button").click(function(){
        // change the class of li elements in the page
        $("li").toggleClass(function(n){
            // with a value depending on the number of li element in 
            // the array of li elements
            return "listitem_" + n;
        });
  });

如果有的话,将添加从<代码>至ggleClass规定的功能中退还的类别,如果确实存在,则予以删除。

<>代码>n para amount is the index of the content in the node list, so the first content will have a category of list_0", and so on...

when the element with the ID "button" is clicked The class listitem_[0-9] is added or removed from any li element depending on if it does or does not already have that class.

   $(document).ready(function(){  // document load, ready to execute code
      $("button").click(function(){  // when all html elements that have a tag named  button  is clicked
        $("li").toggleClass(function(n){ // change the class of all li elements in the page to the "listitem_" + the number of li elements on the page
          return "listitem_" + n; 
        }); 
      });
