Safari - Web site Crashing in iOS 6.0.1 and not in iOS 5.x - safari

Question

I'm trying to open the following URL in iPad 3 Safari browser.
http://www.pearsonschool.com/index.cfm?locator=PS1yJe&PMDbProgramId=110081&sampleId=11241
And doing the following steps:
Click on "Explore the innovative technology of Teacher Place for yourself"
On the top left, click on "Dash" -> Teacher Content
Then select CMP3 Grade 7
Click on Accentuate the Negative
Then click on "3" (Multiplying and Dividing..)
Select "Problem 3.1"
Click "Launch" button
Here we have 3 options to expand viz Launch Video, Connecting to Prior or Knowledge and Presenting the Challenge.
Expand all the 3 items by clicking ">" button on right of these options.
Scroll to the bottom
It crashes.
Its working fine on iOS 5 Safari. But its crashing on iOS 6.0.1 Safari.
The following is the message that I noted during crash:
??Jan 31 07:21:13 Happiestminds kernel[0] <Debug>: 008192.238887 wlan.A[568] AppleBCMWLANNetManager::checkRealTimeTraffic(): now 8192.238881625 num entries 4

I couldn't understand why is it crashing in latest safari.... When googled, i found that some URL's saying its problem related to Redirections, some say about bookmarking and some say about memory management. But I couldn't find the exact issue.
Can some one help me in identifying the exact issue please?

Answer 1

You can try to debug the javascript using chrome on mac, add console.log to your code and follow this tutorial:

I've used a proxy installed on my mac in order to debug and trace from ios safari to the chrome dev tools.
I found that on my web app safari crashed when using iframes, css transitions, css overflow property and, the jQuery ready event, not all at the same time, obviously.

Answer 2

As and when there's updates in the browsers, we have to change the javascript etc respectively in the code as well.
