如何从 Chrome 的 Javascript 控制台获取输入? [英] How to get input from Chrome's Javascript console?

问题描述

有没有办法以编程方式从 Google Chrome 的 Javascript 控制台获取输入，类似于 readline() 在 Firefox 中?

Is there a way to programmatically get input from the Javascript Console of Google Chrome, similar to readline() in Firefox?

推荐答案

一个棘手的方法是为窗口对象的属性分配一个 getter

A tricky way to do this is assigning a getter to a property of a window object

Object.defineProperty(window, 'customCommand', {
  get: function() {
    console.log("hey");
    return "hey";
  }
});

因此，当您键入customCommand"(不带括号)时，它会在控制台获取"变量时将您的 console.log 文本打印到控制台.

So when you type "customCommand" (without parenthesis) it will print your console.log text to the console while the console is "getting" the variable.

尽管如此，您仍然需要返回一些东西，而且我不确定如何更改顺序，以便首先返回值，然后显示控制台中的文本.不过这绝对有可能，我已经看到这种情况发生了.

You will still have to return something though, and I'm not sure how you could change the order so that the value is returned first and the text in the console appears second. It's definitely possible though, I've seen this happen.
