我正在尝试向服务器提交表单，但它必须首先由函数验证。然而，即使我声明了该函数，我仍然收到引用错误。另外，当我单击按钮时，即使我没有向按钮添加 click 属性，它也始终会提交。

最佳答案
范围就是一切! save 函数在 .ready 方法中定义，因此只能在该方法中访问。您必须在该范围之外声明此函数:
var onlineStatus = true;
var formObjects = null;
//Local Storage or Send to Server
function save(){
//stuff here
}
jQuery(document).ready(function($){
