我有一個Wordpress頁面，當某人點擊複選框時，我正在運行一些jQuery來顯示和隱藏2個輸入字段。問題是這段代碼在我的主頁上完美運行，但是當我嘗試在子頁面上執行相同的操作（使用完全相同的html結構& jquery）時，它不再有效。這並不是說文件沒有被加載，因爲jQuery文件的一部分在該頁面上運行良好，我甚至在文件的末尾有一個console.log文件來顯示文件已完全加載。jQuery不能在特定的Wordpress頁面上運行
www.yogagids.nl是主頁，當你點擊複選框「Evenementen」2 datepicker字段顯示時，取消選擇它們，它們被隱藏。這就是它應該如何工作。
www.yogagids.nl/listings這是不起作用的頁面。同樣的故事，點擊「evenementen」複選框，2個日期選擇器字段應該顯示並隱藏。但是在這個頁面上沒有任何反應
我真的很茫然，任何和所有的幫助將不勝感激。
以下是在此頁面上運行的所有代碼，實際文件較大，但我無法發佈很多字符。

它似乎是一個加載順序問題。在第一次運行代碼時找不到複選框。如果在控制檯中手動運行jQuery（「。listingTypeSelect input [value = event]」）。change（function（）{console.log（'clicked'）;}）;點擊處理程序將附加到該複選框。我不知道頁面是如何生成的，但是如果您有權訪問右側部分被渲染的回調函數，則應該使用它來調用此腳本。爲了測試這個理論，添加一個console.log（jQuery（「。listingTypeSelect input [value = event]」））並查看它是否返回任何東西。 – dmoo
