问题

我想从控制台接收输入并处理它以供另一个函数使用。是否有方法可以做到这一点，而不是在将它们记录到控制台之前将这些数据设置为变量？

I want to take input from the console and process it for another function.
Is there any way to do that instead of setting those datas as variable before logging them to console.

I tried every possible ways as solutions and read multiple blogs but none of them giving efficient answer in this case. Especially when it comes to JavaScript console.

I can't set them as variable before this script completely compiled. So is there any way to collect those datas from console.

你可以通过提示框轻松实现如下：

const input = prompt("What's your name?");
console.log(input);

英文:

You can do so via prompt as easy as:

const input = prompt(&quot;What&#39;s your name?&quot;);
console.log(input);

以下是代码中需要打印到控制台的部分：

console.log(
'OS: ' + jscd.os + ' ' + jscd.osVersion + '\n' +
'Browser: ' + jscd.browser + ' ' + jscd.browserMajorVersion +
' (' + jscd.browserVersion + ')\n' + 
'Mobile: ' + jscd.mobile + '\n' +
'Flash: ' + jscd.flashVersion + '\n' +
'Cookies: ' + jscd.cookies + '\n' +
'Screen Size: ' + jscd.screen + '\n\n' +
'Full User Agent: ' + navigator.userAgent
);

这些内容将在控制台输出。如果您想在 JavaScript 中重用这些值，只需引用相应的变量。例如，操作系统存储在JavaScript变量jscd.os中，其版本存储在JavaScript变量jscd.osVersion中。

英文:

These lines in the code you are presenting:

console.log(
&#39;OS: &#39; + jscd.os +&#39; &#39;+ jscd.osVersion + &#39;\n&#39; +
&#39;Browser: &#39; + jscd.browser +&#39; &#39;+ jscd.browserMajorVersion +
&#39; (&#39; + jscd.browserVersion + &#39;)\n&#39; + 
&#39;Mobile: &#39; + jscd.mobile + &#39;\n&#39; +
&#39;Flash: &#39; + jscd.flashVersion + &#39;\n&#39; +
&#39;Cookies: &#39; + jscd.cookies + &#39;\n&#39; +
&#39;Screen Size: &#39; + jscd.screen + &#39;\n\n&#39; +
&#39;Full User Agent: &#39; + navigator.userAgent
);
