Safari double-tap scroll question

[colmaclean]

Just wondering about the double-tap to scroll up/down functionality in Mobile Safari.

Sometimes if reading a web page, when I double-tap at the screen bottom, the page only scrolls up around 25%. Other times on the same page it scrolls 75%.

Anyone know what triggers this varying behaviour and how it can be controlled?

Do you mean: double tap to 'zoom'? If so, the zoom will fit to the width of whatever you double tap on. For example, if you are looking at this thread on your iPhone, and you double tap on the body of text in your post, it will zoom in to fit exactly the text in your post. But if I double tapped on your user name to the left, it will zoom in to fit that section of text, which will have higher zoom since the section isn't that wide.

Does that make sense?

Makes sense, but not what I'm after! I'm well aware of the zoom facility...

I mean the double-tap you can perform near the top or bottom of Safari's screen which scrolls the page up or down respectively.

I haven't noticed this before, but I think that it really just zooms to the part of page you double-tap, giving the impression of a downwards scroll.

If you tap the status bar in Safari, it will jump to the top of the page. I don't know of any way to quickly scroll to the bottom of a page, however. If you find a way to do that, I'd LOVE to know about it.

Well, that's the thing - sometimes a double-tap will scroll the tapped area past the centre of the visible page, so it's not "zooming in" on that point.

The behaviour is most noticeable when zoomed in on one column of text.

There doesn't seem to be any consistency in how far the page scrolls - tapping the same point on the screen sometimes scrolls 25% and sometimes up to 75%!

How much it scrolls depending on how much there is left of the column you're reading.

Ever notice that the block of text that you've double-tapped on usually ends up in the 'center' of your screen? If you tap something that's already in the middle of your screen, it won't 'scroll' at all, just pure zoom. If you tap of a block of text that is mostly below the screen, it will, zoom AND 'scroll' so that the block fits the width and centers.

If this still isn't what you're trying to say, maybe some screenshots will help.

So it's centring on the selected paragraph, not where you're tapping within that paragraph. Explains my question perfectly, thanks!

Zooming not scrolling is my new mantra...

Yeah, there's a way. You use bookmarks. See this thread.

The "scroll to bottom" bookmarklet didn't work on my 3GS the last time I tried it.

Well, did you try any of the other ones (like "find")? If none work, you might be erasing the wrong part of the bookmark text. It's quite a pain to get to the right spot (right before the javascript) to delete the text, but I've used this and other methods all the time and they all work.
