问题 Is there any way to add a frame to the bottom of a web page using a Greasemonkey script? I want to write a script that adds http://www.google.com at the bottom of every web page, inside a frame. I also want the width and height of the frame to be the same as the height of the page that is inside it. 回答1: This is 3 questions in one.

问题 I have a Rails app that is using two subdomains which would like to communicate in JavaScript. What would be the most DRY way to effectively set document.domain = mydomain.com ?

问题 I am trying to design a web page (PHP) that extracts certain elements loaded up by and external website and displays it in my own format on my website. I have seen many things regarding this, but they all seem to work with a the Same Site Origin Policy only.

The code to load the image is as follows: var image = new Image(); image.onload = loadCallback; image.crossOrigin = "anonymous"; image.src = imageSrc; A few questions: Is there something I am missing that is specific to Firefox? Does it require more headers than

问题 On this page: http://code.google.com/apis/accounts/docs/OAuth2UserAgent.html Google gives instructions for doing oauth with client side applications that talk to their apis. One step is to call their token validation api. But if I want to do this from javascript, it would require an ajax request which is cross domain.

问题 I have a site written in Delphi that needs to get data from a .NET web service. In order to consume the web service I am attaching to a .NET web site first that contains a wizard that the end user has to fill out, which in turn is then calling the web service in order to populate AJAX drop-down lists and to return data to the calling Delphi web application.
