Help me fix this document.write javascript code

Help me fix this document.write javascript code

(OP)

Hello Guys
Can someone help me with this javascript code? accessibility test and lighhouse test gave me warning about the use of document.write

Quote:

For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds

image resizing triggered several times on my homepage and post page with document.write method
can someone suggest me better solution for document.write alternative?or fix this code

thanks

CODE

<article><div class='post hentry'>
          <a expr:name='data:post.id'/>
          <b:if cond='data:blog.pageType != &quot;item&quot;'>
      <b:if cond='data:blog.pageType != &quot;static_page&quot;'>
      <b:if cond='data:blog.pageType == &quot;index&quot;'>
      <b:if cond='data:post.isFirstPost'>

      var default_thumbnail="img.jpg";
      if(show_default_thumbnail == true && image_url == "") image_url= default_thumbnail;
      image_tag='<img src="'+image_url.replace('/s72-c/','/s'+image_size+'-c/')+'" class="post-thumbnail" alt="more '+post_title+'"/>';

RE: Help me fix this document.write javascript code

For a standard print type statement, you are best off creating a HTML element with an ID and then using that as the reference to update it.

suggest you look at the DOM, there are many docs on line about how to dynamically add HTML elements to it, and packages like JQuery that will make it easier and handle browser support etc for your list part of the question.

dynamically changing content is never overly great for disabled users tools such as screen readers, but some are better than others.
