How to scroll down with jquery when user reached a specific part of an image?



It's hard to describe what exactly i was looking for and sorry for my english. What i want to do is, while user scroll down slowly, when user reached a specific point, starting to scroll down page like 1000px and then stop scrolling at the second specific point.





Here is an example:

It should be cross browser compatible.

  1. You can use jQuery, hook onto $(document).scroll(). Whenever the scrollTop passes a certain threshold, make it smooth scroll down to the end point.

    $(document).scroll(function() {
    if ($(document).scrollTop() > ####) {
    smoothScrollTo(###);
    }
    });

  2. Ok so I would use setTimout to check the scroll position every so often and then if the scroll position is right, scare the user or whatever you are planning:

    var checkScroll = function() {
    if(window.scrollY > 1000) {
    setTimeout(checkScroll, 100);
    }
    else {
    doSomeScaryStuff()
    }
    }

    // need to call it manually the first time
    checkScroll();


    make sense?

  3. Detect the current position of the top of the window using http://api.jquery.com/scrollTop/ and the window element, and use the same method combined with .animate() to smooth scroll down.

    Hope that helps!

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
