The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

load remote php script after page loads with javascript

Zones: JavaScript, Miscellaneous Programming
Tags: load, page, after, script, php, javascript
Hi

I am trying to figure this out.
remote server A has a php script that queries the database.
I place code on any web page <script type="text/javascript" src="http://mysite.com/syndication/adplace.php?pub=1210139151" ></script>
This works but I want to call the remote server after the users page has loaded. The reason being if remote server A is running slow than it won't lag the web page loading. I will put a timeout solution on server A script if server is processing slow but I need to give it a chance first plus not hinder other web sites.

I have tried this:

 <script type="text/javascript" id="my_script" ></script>
      <script type="text/javascript">
      function my_init() {
                  // load the script
                  document.getElementById("my_script").src = "http://mysite.com/syndication/adplace.php?pub=1210139151";
      }
      if (window.addEventListener) {
            window.addEventListener("load", my_init, false);
      } else if (window.attachEvent) {
            window.attachEvent("onload", my_init);
      }
      </script>

</head>


Blank screen

If anyone has a good crossbrowser solution I would be very thankful!

I like to use the Yahoo User Interface Get library to progressively manage script loading.

It's cross browser and works fine, and the js libraries can be locally or remotely hosted.

No, I don't know what that code really does as I think there must be a simple way.....
      <script type="text/javascript">
      function my_init() {
                  // load the script
                  document.getElementById("my_script").src = "http://mysite.com/syndication/adplace.php?pub=1210139151";
      }
      if (window.addEventListener) {
            window.addEventListener("load", my_init, false);
      } else if (window.attachEvent) {
            window.attachEvent("onload", my_init);
      }
      </script>
<script type="text/javascript" id="my_script" ></script>

This code does access the remote server but doesn't render anything. I can see it working when a page loads and can see that adplace.php was accessed in the log. Why is it not rendering the same as a <script src=""></script > call?

Hi, thanks for your replies but neither are the solution. This must be it but I am missing something because I can see it saying data loading and in the web log.
<script type="text/javascript">
      function my_init() {
                  // load the script
                  document.getElementById("my_script").src = "http://mysite.com/syndication/adplace.php?pub=1210139151";
      }
      if (window.addEventListener) {
            window.addEventListener("load", my_init, false);
      } else if (window.attachEvent) {
            window.attachEvent("onload", my_init);
      }
      </script>
<script type="text/javascript" id="my_script" ></script>

I have no problem accessing the page with a straight javascript src url and pulling data but it should only happen after the page has loaded and
<script type="text/javascript" src="somewhere/my_script.php" ></script> loads on page load so if that server for somewhere is slow than it could take forever to load client pages. Nobody will support my endeavour if I slow there sites down.
I have spent so much time on something that probably for a javascript pro would be nothing.
Any other ideas would be appreciated!

If all goes according to plan, the <src> attribute will be set upon page load - your page, not the remote page.

Then the <src> attribute is set, and all bets are off.

Try this:
1:

<script type="text/javascript" id="my_script" defer='defer'></script>

The defer as I understand is not very compatible with most common browsers.

I have found a solution:
<div id="skgads"></div> anywhere on the page


At the very bottom before the </body> I added this
<div id="skgsites" style="display: none;">  <script src="http://www.mysite.com/syndication/adplace.php?pub=1210139151"></script></div>
<script type="text/javascript">  var skgads     = document.getElementById('skgads'),      skgsites = document.getElementById('skgsites');  skgads.innerHTML = skgsites.innerHTML;  skgsites.innerHTML = '';</script>

The page loads and my remote server does it thing and we are all happy!
Now I can code a timeout on the remote script so if the crappy server can't serve than exit and show an image or something.


Any comments would be appreciated
