我的计算机上的云功能可以使用 Javascript，但是当我使用 TypeScript 尝试它时，它不会编译为 Javascript。它不会创建 lib/index.js 事件

当我运行 firebase 部署时，它显示以下错误

Error: There was an error reading functions/package.json:\n

firebase deploy --debug 显示以下日志：

我收到错误:

LINQ to Entities does not recognize the method 'Int32 LastIndexOf(System.String)' 
method, and this method cannot be translated into a store expression.

使用此代码判断某人的姓氏是否以某些字符开头时:

persons = persons.Where(c => c.FullName.IndexOf(" ") > 0 &&
c.FullName.Substring(c.FullName.LastIndexOf(" ")+1).StartsWith(lastNameSearch));

任何线索如何在不使用LastIndexOf()的情况下实现这一目标？也许在使用ToList()从数据库中获取结果后,我必须检查这个？

如何从 javascript 变量中删除所有文本字符（不是数字或浮点数）？

function deduct(){
    var getamt= document.getElementById('cf').value; //eg: "Amount is 1000"
    var value1 = 100;
    var getamt2 = (value1-getamt);
    document.getElementById('rf').value=getamt2;
}

我想要getamt作为号码。parseInt正在给出NaN结果。

在我的 JavaScript 中，我start在一些 swift 代码上调用一个方法：

import {NativeModules} from "react-native";

// somewhere in JS
NativeModules.MyTestClass.start();
// somewhere else I'm listening for events from the swift code
const myModule = new NativeEventEmitter(NativeModules.MyTestClass);
const subscription = myModule.addListener("testEvent", message => {
  console.log(message);
});

SWIFT代码：

import Foundation

@objc(MyTestClass)
class MyTestClass: RCTEventEmitter {
  let testEventName = "testEvent"

  override func supportedEvents() -> [String]! {
    return [testEventName]
  }

  @objc func start() -> Void {
    let timer = Timer.scheduledTimer(
        timeInterval: 0.1,
        target: self,
        selector: #selector(self.update),
        userInfo: nil, …

在实体框架中,我正在使用一个带有自引用列的表,这个列是这样创建的,我无法更改此结构,因为它已经在项目中使用了太多位置:

Entities
--------
CreationDate         | EntityID | OriginalEntityID |    Name
2014-01-02 10:02:02  |   819    |        NULL      | First draft
2014-02-05 14:04:20  |   899    |        819       | Second draft
2014-05-16 02:45:40  |   907    |        819       | Third draft
2014-05-16 02:45:40  |   908    |        NULL      | Other entity

然后还有另一张表就像这样:

EntityValues
------------
EntityValueID | Value | EntityID
       1      |  20   | 819
       2      |  30   | 899
       3      |  25   | 899
       4      |  12   | 907
       5      |  20   | 908
       6 …

我目前正在评估Windows Azure中的新Azure搜索功能.我想知道是否有办法在文档文本中执行类似于lucene/elasticsearch的更多类似于此问题的查询？ - 获取并获取与传入文档类似的文档列表.我知道Azure Search在后台使用elasticsearch(Source).

我没有在API中的任何地方找到它,但也许我遗漏了参数中隐藏的内容.我认为这是一个非常有用的功能,如果它不包括在内会很遗憾.

我怎样才能使用foreach呢？我想显示所有的名字.

test: [{
    id: "1",
    name: "Tname1"
}, {
    id: "2",
    name: "Tname2"
}]

它不起作用:

this.test.forEach(function(s){
    console.log(s.name);
});
