我不明白，因为该函数已定义，并且 handleAddDokumentAction 和 handleSaveDokumentaction 不会引起任何问题。我确信这是一件小而琐碎的事情，但我就是看不到它。我特别困惑，因为昨天它似乎工作得很好。相关PHP：

Answer 1

您只是拼写错误：

将块替换为handleSaveAlldokumenterAction以下内容：

function handleSaveAllDokumenterAction() {
$('.wldk-kurser-save-all-dokumenter').on('click', function (event) {
    event.preventDefault();

    $('.wldk-kurser-dokument .wldk-kurser-save-dokument').trigger('click');
});
}

Answer 2

var test=function(){
  alert('here');
}
(function ($, context) {
  $(document).ready(function () { 
      test();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

调用时未定义您的函数。尝试用全局变量定义一个函数，并且可以从任何地方调用它。然后不会出现未定义的问题
