我是一名學生,我試圖在用戶點擊gif時啓動,暫停和啓動gif,但是我一直在如何添加此點擊功能。我知道對象的gif版本是.images.fixed_height.url,靜止圖像是.images.fixed_height_still.url。如果我嘗試追加$(this),我得到的圖像是未定義的。我怎麼會這樣做呢?目前,當您點擊該類別時,會顯示10個gif。感謝您提前提供任何幫助。如何使用jQuery暫停和啓動gif AJAX

這是一個了不起的解決方案!爲什麼選擇$('body')而不是$(document)? – willking
在我的項目中習慣了這種類型。我們在身體上發射事件。 :-) – karthick
有道理,再次感謝您的幫助@karthick! – willking
