问题 I've googled everywhere - my site has no fixed heights, no fixed placements. It shows the viewport as I'd like, but ONLY that. It doesn't scroll or show anything else. What am I missing? I've tried all sort of overflow options, nothing seems to be working. 回答1: I would do the following... I would first temporarily disable/remove the stylesheets to make sure everything is spiffy as plain html (if you still have an issue without the stylsheets, there is probably a js script wrecking chaos) I

问题 I'm looking for an SMS gateway to send text messages over an HTTP interface. However, some SMS gateways do not allow to set the sender ID, and those who allow it either require the user to prove that the sender ID is his own mobile phone number, or they manually check each sender ID to prevent SMS Spoofing. For my application, however, I need to be able to set the sender ID as part of the HTTP request. Depending on the number of users, I might have thousands of different sender IDs, and I

问题 I want to get a callback when the screen is changed, so I can stop my recurring request that runs on that specific screen. “dispose” is only called when Navigator.pop is used, but not when Navigator.push is called.

问题 I have saved data on the client side with phonegap using localstorage and now I would like to access that saved data with java code. Is this possible? How can I do this? Thanks. 回答1: Why don't you make a native plugin that stores values in android shared preferences and call it each time you add/delete objects in the localstorage. So, in javascript you don't directly call the localstorage functions, but a wrapper which 1) manipulates the localstorage and then 2) calls the plugin to store it

问题 I am using the slimscrollbar plugin. It is working fine in Web Browser, but its very slow in mobile browser. Any solution to increase the speed that work for mobile? 回答1: If you have used the slimscrollbar plugin found here: http://rocha.la/jQuery-slimScroll you may want to change the setting of "touchScrollStep" to round 50. The default is 200 which is pretty slow, less than 200 is faster and -200 is inverted scrolling "natural". Some code: $('#slimscroll').slimScroll({ size: '5px', height:

问题 I'm laying out an email to be viewed across browsers and mobile platforms and mostly all is going well. It's laid out in tables, using inline styling etc. However, despite a media-query to the effect of a 600px max-width, the Gmail app on at least my and one other Android I have access to is opting to resize the images and layout to fit into it's area instead of using the media query or letting it fit itself into the window normally, either of which would be fine. For personal use, I'm able
