Question

Will static page content wait to load until an AJAX script gets its content?

Answer 1

+1 A:

Normally it's the second case: page loads first, then you add ajax response to div.

You can write synchronous ajax request which would stop rendering until response received, but that doesn't seem like a good choice to me.

Answer 2

A:

Perhaps you misunderstand the idea behind AJAX. If not, then I misunderstand your question.

If site 1 runs a PHP script that echoes content from site 2, that PHP script will wait until it gets site 2's content before continuing with the rest of the script. However, if site 1's PHP script sends some JavaScript to the client, then the PHP script on site 1 will run without sending any request to site 2 and that JavaScript will request site 2 for its content.

My apologies if I misunderstand your question.

Answer 3

+1 A:

If you do it on Page Load, your DOM will render first before displaying the AJAX loaded content. Page_Load means that the function will wait until.. well... the page is loaded.

If you didn't want this to happen you could have the script running AS part of the Page Load, with inline Javascript.

Say your function was in your <head> section.

<head>
  <script type="text/javascript>
    function alertMe() {
      alert("hello world!");
    }
  </script>
</head>

Then at the start of your <body> section, you could call that function.

<body>
  <script type="text/javascript">
    alertMe();
  </script>
  <!-- Other page content -->
</body>

This might not be good practice however, since the other website might not be available, and may cause your entire page to time out or annoy the user because your website is taking longer to load.

It's pretty common practise to load AJAX, AFTER your page is loaded, so I would go with option #1.
