This question already has an answer here:

I have problem in retrieving the HTML code containing JavaScript.

What I expect is the HTML code in which the JavaScript has been executed and only pure HTML in it like the output of browsers(e.g. Chrome).

I mean I hope that there is a Linux command or a way downloads HTML, execute JavaScript and output the page. (curl can download the page, but cannot execute the JavaScript)

This is a great use case for Node.JS and Phantom.JS. Here's a presentation that touches exactly this topic - retrieving data from dynamic pages - http://vimeo.com/66992296.

Quote from Phantom.JS website:

PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

So, it is a web browser that works on your server. You just need to talk to it from your script. And you can do this using e.g. phantomjs-node module for Node.JS.
