Question

我正在尝试将表单提交给服务器，但必须首先通过函数进行验证。但是，即使我声明了函数，我仍然会获得引用错误。此外，当我单击按钮时，即使我没有将click属性添加到按钮，它也会一直提交。

Answer 1

范围就是一切！ save函数在.ready方法中定义，因此只能在那里访问。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($){

我在表单提交按钮的单击事件上调用函数时出现引用错误
