如何在不使用document.write（）的情况下在Javascript中开始新行？

Question

 var infoDiv = document.getElementById("info"); console.log(window); console.log(window.location); infoDiv.textContent += "The URL of this page is " + window.location.href; // i am hoping the following sentence can start in a new line infoDiv.textContent += "The user agent is " + window.navigator.userAgent; 

I tried document.write("\\n") as people suggested here , but Chrome gives me this violation warning:

[Violation] Avoid using document.write(). https://developers.google.com/web/updates/2016/08/removing-document-write

What should I do? Thanks!

Answer 1

Line breaks in HTML are created with the <br> element (generally between text nodes). Paragraphs with the <p> element (generally around text nodes).

In either case you'll need to stop twiddling textContent because it will wipe out any elements you create.

Use document.createElement , document.createTextNode , and infoDiv.appendChild .

Answer 2

You can append elements instead of text:

var infoDiv = document.getElementById("info");
infoDiv.append("The URL of this page is " + window.location.href);
// append new line
infoDiv.append(document.createElement('br'));
infoDiv.append("The user agent is " + window.navigator.userAgent);
