Select appended item jquery
提问by Xavier
How would i select the below item, i do notwant to select every LI of .topbut just the LI i have just created on the append.
我将如何选择以下项目，我不希望选择的每一个LI.top只是我刚才在追加创建LI。
How is this possible?
这怎么可能？
$('.top').append('<li><span>' + html + '</span></li>');
采纳答案by Matt Ball
Use the :lastpseudo-class selector.
使用:last伪类选择器。
$('.top > li:last')
Alternate option: consider creating the element slightly differently.
替代选项：考虑稍微不同地创建元素。
var $li = $('<li><span>' + html + '</span></li>');
$('.top').append($li);
// you already have the <li> selected, in $li
回答by Richard Dalton
You could do it the other way around using appendTo()
你可以用另一种方式来做 appendTo()
var li = $('<li><span>' + html + '</span></li>').appendTo('.top');
This way you don't have to select it after appending it.
这样您就不必在附加后选择它。
