一、Android和IOS的内置键盘(Native keyboard)是不一样的
对手机的内置键盘的操作是比较复杂和富有争议的,不同的手机可能需要不同的css。Android使用的是第三方的键盘插件(3rd party keyboards ),如 Google Keyboard 和 SwiftKey。
可设置input的type属性来决定内置键盘是显示数字键盘还是显示字母键盘(参考link):
- Email:<input type="email" name="email">
- URL: <input type="url" name="url">
- telephone: <input type="tel" name="tel">
- number:<input type="number" name="number">
- Date:<input type="date" name="date">(chrome)
- Time:<input type="time" name="time">
需要说明的是:
- android不支持input的type属性,而IOS支持
- android的内置数字键盘没有小数点按钮
- 浏览器对date/time的支持很有限,Opera支持以上所有的属性,chrome支持date,safari支持date但不支持calender
二、page events的顺序
如从A页面转到B页面(Navigate from A to B)
- page B---pagebeforecreate
- page B---pagecreate
- page B---pageinit
- page A---pagebeforehide
- page B---pagebeforeshow
- page A---pageremove
- page A---pagehide
- page B---pageshow
三、jQuery Mobile transitions
jQuery Mobile的页面转换常会出现(Flickering/Blinking)闪烁问题,为此可以在viewport meta tag中关闭(disabling)jQuery Mobile的页面转换。
- Android 2.3不支持CSS3 transition
- "pop" 转换效果在跳转前会将背景变成白色,导致出现“闪烁”效果(解决方法:将pop转换效果变为旧jQuery Mobile效果的插件,参见here)
四、 Fixed Header and Footer
jQuery Mobile内置有固定位置的header和footer,但一些低版本的Android和IOS不支持,需要另外修正
1)加data-tap-toggle="false"到header和footer
2) 如IOS 6, 7 ,8的hack如下
if (iOS()) { $(document).on('blur', 'input:not(:submit), select, textarea', function () { var paddingBottom = parseFloat($(".ui-mobile-viewport, .ui-page-active").css("padding-bottom")); $(".ui-mobile-viewport, .ui-page-active").css("padding-bottom", (paddingBottom + 1) + "px"); window.setTimeout(function () { $(".ui-mobile-viewport, .ui-page-active").css("padding-bottom", paddingBottom + "px"); }, 0); }); } var iOS() = function () { var userAgent = window.navigator.userAgent.toLowerCase(); return (/iphone|ipad|ipod/).test(userAgent); }
3)或参见:JQueryMobile - fixed footer not fixed after input focus
$('div:jqmData(role="page")').on('pageinit',function(){
$(document)
.on('focus','input, select, textarea', function(){
$('[data-role="footer"][data-position="fixed"]').hide();
})
.on('blur','input, select, textarea',function(){
$('[data-role="footer"][data-position="fixed"]').show();
});
});
有时候当toolbar滚动过快的时候会导致不平滑问题。
五、更多的Javascript的Events
- tap:Triggers after a quick, complete touch event.
- taphold:Triggers after a held complete touch event (close to one second).
- swipe: Triggers when a horizontal drag of 30px or more (and less than 20px vertically) occurs within 1 second duration.
- swipeleft: Triggers when a swipe event occurred moving in the left direction.
- swiperight: Triggers when a swipe event occurred moving in the right direction.
- Triggers when a scroll begins. Note that iOS devices freeze DOM manipulation during scroll, queuing them to apply when the scroll finishes. We're currently investigating ways to allow DOM manipulations to apply before a scroll starts.
- Triggers when a scroll finishes.
