How to prevent app running in phone-gap from scrolling vertically?
I'm trying out phone gap and I want my application to not scroll up and down when the user drags their finger across the screen. This is my code. Can anyone tell me why it's still allowing scrolling?

if you're using Cordova 2.3.0+ find config.xml and add this line:
<preference name="UIWebViewBounce" value="false" />
or in Cordova 2.6.0+:
<preference name="DisallowOverscroll" value="true" />
Run this code when the page is loaded to disable dragging:
document.addEventListener('touchmove', function(e) { e.preventDefault(); }, false);
Here's an example with jQuery:
$(document).ready(function() {
document.addEventListener('touchmove', function(e) { e.preventDefault(); }, false);
});
in your config file use
<preference name="webviewbounce" value="false" />
<preference name="DisallowOverscroll" value="true" />
if you're using Cordova 2.6.0+ find config.xml, just add/modify this line:
<preference name="DisallowOverscroll" value="true" />
Add the following entry to config.xml file:
<preference name="DisallowOverscroll" value="true" />
You didn't say if this is a native app or a web app.
If this is a native app you can turn off scrolling on the webview
UIScrollView* scroll; //
for(UIView* theWebSubView in self.webView.subviews){ // where self.webView is the webview you want to stop scrolling.
if([theWebSubView isKindOfClass:[UIScrollView class] ]){
scroll = (UIScrollView*) theWebSubView;
scroll.scrollEnabled = false;
scroll.bounces = false;
}
}
otherwise here is a link on the phonegap wiki for preventing scrolling. http://wiki.phonegap.com/w/page/16494815/Preventing-Scrolling-on-iPhone-Phonegap-Applications
In config.xml of your project, under preferences for iOS set DisallowOverscroll to true. By default it is false which makes whole view to scroll along with inner elements of the view.
<preference name="DisallowOverscroll" value="true" />
For me it work's perfect, when i use the body-selector with jquery. Otherwise i was not able to open external links with Phonegap.
$('body').on('touchmove', function(evt) {
evt.preventDefault();
})
Changed UIWebViewBounce to DisallowOverscroll in 2.6.0
now you just have to put <preference name="DisallowOverscroll" value="false" /> to <preference name="DisallowOverscroll" value="true" /> in your config.xml file.
Go native and add this line to the AppDelegate.m file
self.viewController.webView.scrollView.scrollEnabled = false;
Drop it in the - (BOOL)application:(UIApplication)application didFinishLaunchingWithOptions* section.
At first what you have to do is you should add the event listener in body unload method.
simply put this line in the touch move method.
it won't scroll document.addEventListener("touchstart/touchmove/touchend"). Any one of these 3.
function touchMove (event e) {
e.preventDefault;
}
If you have UIWebViewBounce to NO in your .plist file.
Then with simple css would make the content not scrollable. Try Adding this style overflow : hidden in your div where you want to disable the scroll.
In config.xml of your project, under preferences for iOS set DisallowOverscroll to true.
