How to get current date and time in TypeScript
提问by fidgetyphi
Summary
概括
I'm creating my first extension for VSCode in TypeScript, and want to create a new information message to display current date/time.
我正在 TypeScript 中为 VSCode 创建我的第一个扩展，并且想要创建一个新的信息消息来显示当前日期/时间。
What I've tried
我试过的
I've tried looking for some data/time keyword in the list of vscode key bindings. I've also tried looking for a function to get system date/time on Google only to come across solutions explaining data/time syntax and how to display a specific date/time but nothing to get the CURRENT data/time. I've also looked for it in vscode API documentation.
我试过在 vscode 键绑定列表中寻找一些数据/时间关键字。我还尝试在 Google 上寻找一个函数来获取系统日期/时间，只是为了遇到解释数据/时间语法以及如何显示特定日期/时间但没有获取当前数据/时间的解决方案。我也在 vscode API 文档中寻找过它。
Code part
代码部分
According to my understanding the code should be in extension.tsfile in activatesection where I register the command to implement showInformationMessagefunction call and send a string to it containing the date/time. So here is the code around the line where I store the current date/time:
根据我的理解，代码应该在我注册命令以实现函数调用的部分的extension.ts文件中activate，showInformationMessage并向它发送一个包含日期/时间的字符串。所以这里是我存储当前日期/时间的那一行的代码：
let disposableShowTime = vscode.commands.registerCommand(
"extension.showTime",
() => {
// Display a message box to the user
let dateTime = "22 March, 2019 12:45PM"; // store current data/time instead
vscode.window.showInformationMessage("Current time: " + dateTime);
}
);
Desired output: [Current Date/Time]
所需的输出：[Current Date/Time]
Actual output: 22 March, 2019 12:45PM
实际输出：22 March, 2019 12:45PM

To retrieve the current system Date/Time in javaScript/TypeScript you need to create a new Dateobject using parameterless constructor, like this:
要在 javaScript/TypeScript 中检索当前系统日期/时间，您需要Date使用无参数构造函数创建一个新对象，如下所示：
let dateTime = new Date()
