How can I use #RenderPage with JavaScript or jQuery page load? I've tried this but it's not working:
$("#ActivePageContent").load('#RenderPage("/Views/Port.cshtml")');
You're confusing server-side with client-side code. #RenderPage is just going to dump the rendered HTML of your view directly into Response. You can examine the source of your page to verify. You'll have something that looks a lot like...
$("#ActivePageContent").load('<html><head><title>Some Page</title>...');
It's unclear what you're really trying to do with your jQuery load() method, but #RenderPage isn't going to get you there.
From jQuery, load() is supposed to take a URL:
$( "#result" ).load( "ajax/test.html" );
Maybe you meant to write something like this instead?
$("#ActivePageContent").load('#Url.Action("Port", "MyController")');

well, I have a comment system that is updated every second with jQuery, but I want to update only if there are changes, that is, only if there are new records in the database. is there a way to do this?
Excuse my English, but I'm using google translator
You may create two function in JS. First function ask php script, which check changes, and, if data changed, run second JS function, which get data and update DOM.
Php is not may send info on loaded http page independently, without request from client side.

Posting data to the server needs a form-tag.
But do I also need a button of type 'submit' when I use ajax/jquery?
Can I not just interrupt the button click and do my own ajax request?
No, and technically you don't even need a form tag if you want to serialize the POST data yourself.
If you are using Ajax then you don't technically, need a form tag or a submit button.
Having them gives you convenient, semantic elements with logical events to bind the JavaScript to.
Having them is needed for the JS to be unobtrusive (which is a best practise).

I am new in web development i want call web service which give response in Json in my HTML page using javascript or Jquery. Also Json parsing in Javascript or Jquery.
Thank you in advance.
I am new in web development : Every Expert was beginner in start.
i want call web service which give response in Json in my HTML page using javascript or Jquery. : most probably ajax is used here
Also Json parsing in Javascript or Jquery. :jQuery has already inbulit methods like parseJson, JSON.parse, JSON.stringify
so there are lot of options, you just need to google it in right way.

Is it possible through javascript to read a file and exexcute it.
for eg if we have written code for button it should read and display actual button as output.
You may use eval https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval
However this is not a good practice and you should avoid it.
I think you are looking for jQuery $.load http://api.jquery.com/load/
$( "#result" ).load( "ajax/test.html" );
In the above code, the load method will load the test.html file and put it contents with in the div with id result for e.g.
<div id="result"></div>

So i'm using phonegap build with, html5 jqm and javascript and css obviously.
i have a local rss feed in xml format that has been made and will be updated with new events etc.
i want the RSS feed to show like a list basically at the moment i'm no bothered with anything fancy look as i've not even managed to get it to show up, all my efforts have been futile.
Any answers accepted. For practicality lets call the feed rss.xml.
Thanks!
You may use jfeed, for example
jQuery.getFeed({
url: 'rss.xml',
success: function(feed) {
console,log(feed.title);
}
});
Also, you can use $.get, here is an example for PhoneGap and an article worth reading.
