detecting on screen changes caused by javascript

[lingot 0]

I'm trying to create yahoo mail registration bot and have come across a problem. The check to see if your desired name is available or not is all done in javascript. How would you go about detecting this in ubot? When clicking the 'check' button the the source doesn't change, so scraping it seems useless.

 

Thanks for any help.

To my understanding ubot will be able to scrape it as ubot handles source code a little differently to normal browser. Did you try to scrape it yet? Just add in a delay before you try to scrape it.

Just checked and had no problem scraping this. Field name for me was "yahooIdFldMsg"

Just checked it now and scraping "yahooIdFldMsg" does seem to work. Thanks for the pointer!

Is there anywhere I can read about how ubot handles javascript?

No idea, I just know what I have found in last couple weeks going through the forum. I think ubot reads the rendered source code after the javascript has executed. For instance if a page uses document.write() you will be able to scrape the text written as onpage content.
