JS: document.write

By Xah Lee. Date: . Last updated: .

This page shows a JavaScript example of generating HTML content dynamically using document.write.

The following code prints out numbers from 1 to 9 directly into the page where the JavaScript code is:

document.write("<p>");
for (var i=1; i< 10; i++) { document.write(i + " "); }
document.write("<\/p>");

This is a simple example of inserting text into a document. But this is not a good way.

document.write() is from 1996, when DOM didn't exist. It is a blocking construct. When browser encounters it, it stops everything and run the code. document.write() is not used in modern web applications. 〔►see JS: Browser Window Object, Document Object Model

For a much better way, see: JS: Create HTML Element.
