javascript - FF keeps spinning after document.write()

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

<html>
  <head>
    <script type="text/javascript" >
       function fn() {
       document.write("Hello there!!!");
       }

    </script>
  </head>

   <body>
      <button onclick="fn()">click</button>
   </body>
</html>

After clicking the button , FF keeps on spinning (11.0), while as if I directly call the fn() without wiring it to the button , it works fine.Could anyone please look into this ?

You need to call document.close(). document.write calls document.open if the document hasn't been opened. As long as the document isn't closed again with document.close the browser will indicate that the page is subject to change.

function fn() {
    // implicit call to `document.open();` before document.write
    document.write("Hello there!!!");
    document.close();
}
