我想将宿主对象扩展Error
为自定义UploadError
类.编译时,以下示例失败:
class UploadError extends Error {
constructor(message: string, private code: number) {
super(message);
}
getCode(): number {
return this.code;
}
}

当我运行TypeScript编译器时,tsc
我收到以下错误:
UploadError.ts(1,0): A export class may only extend other classes, Error is an interface.

它似乎Error
被定义为一个接口.如果有人知道实现的名称是什么,它会让我很开心:-)
function UploadError (message: string, code: number) {
this.message = message;
this.code = code;
}
UploadError.prototype = new Error();
UploadError.prototype.constructor = UploadError;
UploadError.prototype.getCode = (): number => {
return this.code;
}

除了后者使用额外的桌子之外,您认为更安全/更好的做法是什么?
我开始在网站上的所有内容类型中部署WYMeditor,看起来不错.现在我看到它如何保存和查看,但它没有提交任何东西,我不知道为什么.
我从几个角度看这个.我甚至会在这一点上采用monkeypatch,如果我能学会如何自己获取数据,我可以在提交时将其粘贴到现场.那个或它不能单独工作的真正原因会很棒.谁有想法?

我的一个Facebook应用程序允许用户使用默认的Facebook共享器共享Facebook事件的URL.我的印象是你可以查询这样的URL在Facebook上分享的次数.但是,当我在Facebook上查询一些非常受欢迎的事件时,我得到的结果显示0股,喜欢和评论.
例如
SELECT click_count, comment_count, comments_fbid, commentsbox_count, like_count, normalized_url, share_count, total_count, url
FROM link_stat
WHERE url = 'http://www.facebook.com/events/385623724876261'
