How to simulate JavaScript in a client Applications

2 New Member

Hi Guys.
I'm writing a web crawler (web spider) that crawl all links in a website.
My application is a Win32 App, written in C# with .Net framework 3.5.
Now I'm using HttpWebRequest an HttpWebResponse to communicate with the web server.
I also built my own Http Parser that can parse anything I want.
I found all link like "href", "src", "action"... in the parse.
But I can not solve one problem: Simulate Client Script in the page (like JS and VBS)
For example, if a link like:
<a href="javascrip t:buildLink(1)" > ... with buildLink(param eter) is a Javascript function that will make a custom link due to the parameter.

Please help me to solve this problem. How to simulate JavaScript in this app? I can parse the HTML source code and take all JavaScript code to another file, but how to simulate a function of it?
Thanks.

Well first you're going to have to understand what the JavaScript function does and then translate that into C# code that your application can execute....

It sounds like your application is going to have to translate JavaScript into C#...this is not going to be an easy task and you are going to have to know how JavaScript works so that you can implement an application that knows how to translate it.

Good luck,

If you are going to build it from scratch it's not an easy task. I've a compiler exam tomorrow, not easy at all. Look for libraries you can use ActiveX component, I didn't before, or It will take a long time for "simulating ".

Intercept Ctrl-N (new browser window) from JavaScript?

by: Kai Grossjohann | last post by:

It seems that Ctrl-N in Mozilla opens a new empty browser window. That's fine, I don't need to do anything about it. But Ctrl-N in IE appears to clone the current window. Is there a way to intercept the key so that I can do stuff on the server side to make the new window behave correctly? (We have a JSP-based webapp which stores state in the session. Now if two windows access (and modify!) the same session, then madness will result....

OK, here's the scenario: I have a CGI script that generates a page with frames (BTW, I'm not crazy about frames, but in this case the decision to use them is out of my hands). In a typical session, the user interacts with two of these frames extensively, and up to the very end of the session, this interaction is handled entirely client-side by a fairly elaborate JavaScript script. (This interaction takes place exclusively via HTML...

Using HTML as an application GUI or How do you control an application from Javascript?

I'm currently developing an application in C++/MFC (Visual Studio 6, if that makes a difference) and I'd like to avoid the Windows style UI widgets and dialogs if at all possible.

I'm fairly well experienced with web pages and I've written a fair amount of JavaScript at one time or another...

JavaScript as AJAX response (RPC)

by: petermichaux | last post by:

Hi, Some servers return JavaScript as the response to an AJAX request. When the response JavaScript is eval'ed it calls other JavaScript functions already in the browser to update elements, etc. This seems like a good system because it allows so much freedom in creating the desired behavior in the browser. The required data doesn't have to be converted to XML or JSON on the server. The browser doesn't have to have templates for...

the future of applications in JavaScript?

by: Peter Michaux | last post by:

Hi, I'm sure many here have already noticed this but it seems that the development of the browser world is paralleling the development of the computer world. However, the browser world is about 20 years behind like back in the days of mainframes and dumb terminals just capable of running a window manager. Instead now we have servers and browsers. In a way I make me feel a little like browser scripting is already archaic because this...
