I want to get table data from some website. Which best way to retrieve that data if I use javascript ?
Thanks before
you cant not use JavaScript because you cannot make cross domain requests with it.
if you want to use PHP, you can use "http://simplehtmldom.sourceforge.net" library so you can analyse the html from any website. this library is very easy to use and very helpfull.

I need to add a parameter to all URLs that we use in our campaigns adwords.
Can you help me in that sense?
You've just written your code in explanations. What is the problem to make the explanations in code? Is there something more that the mentioned?
if(isset($_GET['refid']) && $_GET['refid'] == 'adwords') {
setcookie('refid', $_GET['refid'], time()+3600*24*30);
}
if(isset($_COOKIE['refid']) && $_COOKIE['refid'] = 'adwords') {
//display tel number
}
You just need exactly that - if the get parameter exists - assign cookie. If cookie exists - display. It's simple conditions in PHP. If it's only this - you need to learn the basics in PHP.

I am making a http request that returns a url to an image. I would like to display the image in my html page. Is there a way to do this? I idea of what I want to do is (this doesn't work but..) img src={{result.imageurl}}
Yes, you have to use ng-src="{{result.imageurl}}"
See http://docs.angularjs.org/api/ng.directive:ngSrc

Before I had chosen.js I could find the specific option, remove it, and then create a new option instead, giving it the same value as it the deleted option has...
Now it doesn't work... the select itself changes - but it is hidden when using chosen.js...
And what was supposed to be a simple task is not simple at all!
Can someone help me?
Thanks!
Use $("#your_field").trigger("chosen:updated"); after updating select options.
Just as is written in reference: http://harvesthq.github.io/chosen/#change-update-events

I'm looking for a small and lightweight way to get the screenshot of a website with just the URL. I've heard you can do this with XML/PHP, or even use another service to return the image. However, is there a fast simple way to do this? Preferably in Js? Also, to clarify, my project is going to be dynamically generating these thumbnails.
You can't do this with html/php alone. You need a browser to interpret the content on the page and get a screenshot. Some sort of software. OR use a 3party service
http://www.browserstack.com/screenshots/api looks good, I haven't tried them though

Do you have see this page http://google.github.io/tracing-framework/ , it's a amazing animation it there.
You guys know how to generate it ? I sure it isn't by hand.
They're using Javascript and this image which is super huge(along with a few other images you can view in their resources. And you can see the source of one of their js files here.
btdubs - Yes - they ARE using canvas.
Not sure if that answers your question or you wanted something more specific.
