Description

Base UI => Views => Mixing Views

top view is a web with this:

document.body.addEventListener("touchmove", function(e) {e.preventDefault();}, false);

but it still scrolls - this had worked previously

Ran the test against HEAD, Base UI -> Views -> Mixing Views and tried to scroll the web view. With this line in it, it didn't scroll. With the line removed, it did. Seems like preventDefault() works.

which line are you talking about?

Stephen Tramer 2011-04-15

The line in question:

document.body.addEventListener("touchmove", function(e) {e.preventDefault();}, false);

When the HTML reads:

   var html = '<html><body style=";color:#bbb;font-family:Helvetica Neue;text-align:center;">';
   html += '<div style="font-size:20;font-weight:bold;">I am a web view</div>';
   html += '<div id="foo" style="font-size:14;font-weight:bold;">click me</div>';
   html += '<script>document.getElementById("foo").ontouchstart = function()';
   html += '{Ti.App.fireEvent("webview_click");document.body.addEventListener("touchmove", function(e) {e.preventDefault();}, false);};</script>';
   html += '</body></html>';

(with the event listener present) things work. More accurately, it worked in 3.2 simulator.

Additional confirmation on this might be good. I'll test on 3.1 and 4.0 device.

Confirmed. Doesn't work in 3.1, does work in 3.2 and 4.0. Must be a Safari thing.
