Question

I’m trying to make a gadget with “FeedEk jQuery”
but problem is i cant add auto update feed in that code! for example i wanna change and reload feeds every 5 minutes.

Source: http://www.jquery-plugins.net/FeedEK/FeedEK.html

Default Function:

<script type="text/javascript" >
$(document).ready(function(){     
   $('#divRss').FeedEk({
   FeedUrl : 'http://www.my site.ir/rss.xml',
   MaxCount : 5,
   ShowDesc : false,
   ShowPubDate: true
  });  
});
</script>

HTML:

<div id="divRss"></div>

My question is, how i can add auto update or refresh timer for every 5 mins on this jquery code?

And next question is, how i can add word limit for description, for example just 200 word in description.

Answer 1

to explain what I meant in the comment, take the above and wrap it in a function (we’ll call it loadFeed():

<script type="text/javascript" >
$(document).ready(function(){     
  function loadFeed(){ // wrapper function
    $('#divRss').FeedEk({
     FeedUrl : 'http://www.my site.ir/rss.xml',
     MaxCount : 5,
     ShowDesc : false,
     ShowPubDate: true
    }); 
  } // /wrapper
});
</script>

Next, just after it make a direct call to that function so it executed on page load:

loadFeed();

Then, place a recurring call (using setInterval) just below that so it updates:

setInterval(loadFeed, 300 * 1e3); // every 5 minutes [300 seconds]

So, altogether:

<script type="text/javascript" >
$(document).ready(function(){     
  function loadFeed(){ // wrapper function
    $('#divRss').FeedEk({
     FeedUrl : 'http://www.my site.ir/rss.xml',
     MaxCount : 5,
     ShowDesc : false,
     ShowPubDate: true
    }); 
  } // /wrapper
  loadFeed();
  setInterval(loadFeed, 300 * 1e3);
});
</script>

Regarding your second question, you’re probably going to need to open the script and modify the entry.content portion within the $.ajax call so it only shows as much information as you want. If it’s minified (all one line) you can use jsBeautifier to make it a little easier to read and work with.
