compatibility

问题 Just a question about optimization, between : <a href="#" onClick="javascript:window.open('myUrl.com');">link-1</a> and : <a href="javascript:window.open('myUrlBis.com');">link-2</a> Is one better than the other ? Or more compatible ? Thanks. 回答1: Best practice is to use the target attribute: <a href="http://myUrl.com" target="_blank">link-1</a> If that doesn't suit, a click handler (ideally not assigned via attribute) would be my take. 回答2: Neither one Make it a regular link using href and

问题 Recently my application received quite a lot comments that "it's not working" on Android Ice Cream Sandwich with CM9. I'm not able to reproduce the error on the emulator running Android 4.0 and thanks to the way android market works there's no way I can't contact those people to ask about the details. Luckily, one crash error report caught my eye. I'm using Canvas.clipPath to draw rounded corners... and looks like some phones are throwing UnsupportedOperationException when trying to use that

问题 I have a method in my application which retrieves the last saved image in my DCIM/Camera folder and copies it to another location on the SD card. I've just tested it on another phone and found that it defaults saving to DCIM/100MEDIA . How am I able to get this path? I ended up writing some code which looped through all the folders in the DCIM folder and retrieved the path of the lastModified() folder. 回答1: Looks like it is manufacturer dependent. In addition to using methods described in

问题 This question already has answers here : Java 8 support in GWT (2 answers) Closed 3 years ago . I have an application which is developed using GWT 2.6 and Java 7.

People will want to use JQueryMobile earlier versions for a number of good reasons, e.g. if there is regression in later versions, other compatibility

问题 I have problems with Python 3.2 and PyQt 4.8.6 It seems as if Python 3.2 can`t find the imports. Especially the "Q"-methods. For example the QString below. from PyQt4 import QtCore, QtGui try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: _fromUtf8 = lambda s: s With Python 2.7 everything works fine. Where is the mistake in my code? 回答1: Python3 made many incompatible changes in order to "clean up" the language, and, to a certain extent, PyQt has done the same by introducing
