我正試圖建立一個星級評分系統。我現在使用的代碼執行以下操作:5星級評分所需的幫助 - Jquery
高亮明星當鼠標懸停在,但是當鼠標被刪除恢復到以前的狀態。
我想爲其添加以下功能: 當我點擊一顆星星時,即使將星星從鼠標上移開,我點擊的星星數量仍應保持高亮顯示。
任何人都可以幫助我嗎?

我建議在視覺上剛剛超過()'例行過的方式懸停相同設置的收視率在`點擊,然後解除綁定懸停程序。 – Orbling 2010-12-04 02:50:24
我不得不承認我是一個完全新手Jquery的東西。我直覺地感覺到,我必須在//中處理鼠標移動 function(){(this).prevAll()。andSelf()。removeClass('ratings_over'); //不能使用'this',因爲它不會包含 – 2010-12-04 02:59:09
