Document.write()에 의해 열린 문서 스팀에 텍스트 스트링을 적는다.

주: as document.write writes to the document stream, calling document.write on a closed (loaded) document automatically calls, which will clear the document.




document 문성에 씌여질 텍스트를 포함하고 있는 스트링.


  <title>write example</title>

    function newContent() {
      alert("load new content");;
      document.write("<h1>Out with the old - in with the new!</h1>");

<body onload="newContent();">
  <p>Some original document content.</p>


Writing to a document that has already loaded without calling will automatically call Once you have finished writing, it is recommended to call document.close() (en-US) to tell the browser to finish loading the page. The text you write is parsed into the document's structure model. In the example above, the h1 element becomes a node in the document.

If the document.write() call is embedded within an inlined HTML <script> tag, then it will not call For example:

  document.write("<h1>Main title</h1>")
Note: document.write and document.writeln do not work in XHTML documents (you'll get a "Operation is not supported" [NS_ERROR_DOM_NOT_SUPPORTED_ERR] error in the error console). This happens when opening a local file with the .xhtml file extension or for any document served with an application/xhtml+xml MIME type. More information is available in the W3C XHTML FAQ.
Note: document.write in deferred or asynchronous scripts will be ignored, and you'll get a message like "A call to document.write() from an asynchronously-loaded external script was ignored" in the error console.
Note: In Edge only, calling document.write more than once in an iframe causes the error SCRIPT70: Permission denied.
Note: Starting in 55, Chrome will not execute <script> elements injected via document.write() in case of an HTTP cache miss for users on a 2G connection.
