How to select only one sibling with jQuery? 得到一个兄弟元素 有大用

$(this).siblings(".bar").eq(0).text()

That will select the first element in the set. In your case, you could simply use prev, as the element you're looking for comes directly before the clicked element:

$(this).prev(".bar").text()

The problem with the array notation method you were using is that it returns the actual DOM node contained within the jQuery object, and that's not going to have a text method. eq is the equivalent jQuery method to do this.
