这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。
语法
abortSignal.onabort = function() { ... };
示例
在下面例子中, 我们将创建一个新的 AbortController 对象，并获取它的AbortSignal (在 signal 属性中可用)。然后我们查看 onabort 属性是否被终止，并将相应的日志输出到控制台。
var controller = new AbortController();
var signal = controller.signal;
signal.onabort = function() {
console.log('Request aborted');
};
