1.如果网页是在iPhone或Android浏览器中查看，则在主体元素中添加“iPhone”或“Android” 类名

Javascript代码

if (navigator.userAgent.match(/iPhone/i)) {       $('body').addClass('iPhone');   } else if (navigator.userAgent.match(/Android/i)) {            $('body').addClass('Android');   }

iPhone用户浏览示例：

• Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A537a Safari/419.3
• Mozilla/5.0 (iPhone; U; XXXXX like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A477d Safari/419.3

Android用户浏览示例：

• Mozilla/5.0 (Linux; U; Android 2.2; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
• Mozilla/5.0 (Linux; U; Android 1.6; en-gb; Dell Streak Build/Donut AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/ 525.20.1
• Mozilla/5.0 (Linux; U; Android 2.1-update1; de-de; HTC Desire 1.19.161.5 Build/ERE27) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17
• Mozilla/5.0 (Linux; U; Android 2.2; en-us; DROID2 GLOBAL Build/S273) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

2. 移除浏览器地址栏

window.scrollTo(0, 1);

3. 防止网页触摸滚动

notouchmove = function(event) {       event.preventDefault();   }   
     
       ...   
     

4. 当横向浏览时显示信息

var updateorientation = function (){       var classname = '',      top = 100;    switch(window.orientation){          case 0: classname += "normal";break; case -90:classname += "landscape";break; case 90:classname += "landscape";break;     }    if (classname == 'landscape') {         if ($('#overlay').length === 0) {            window.scrollTo(0, 1);            $('body').append('
     
      Landscape view is not supported for this page.
     
');        }      } else {          $('#overlay').remove();    }}; Usage:      var supportsOrientationChange = "onorientationchange" in window,        orientationEvent = supportsOrientationChange ? "orientationchange" : "resize";     window.addEventListener(orientationEvent, function() {    updateorientation(); }, false);

5.显示部分描述信息，当点击时显示完整信息

var truncatedesc = function(trunc, len) {     if (trunc) {        var org = trunc;        if (trunc.length > len) {        trunc = trunc.substring(0, len);          trunc = trunc.replace(/w+$/, '');         trunc = '' + trunc;        trunc += '...';        trunc += '' + org + '';       }       $('.truncated').live("touchstart touchend", function() {         $(this).closest('div').find('.original').show();         $(this).closest('div').find('.truncated').hide();        return false;         });        return trunc;     }  };   Usage: truncatedesc(item.description, 100);

6. 收到成功的Ajax请求时，重定向到另一个页面(jQuery mobile)

var ajaxurl = ‘http://…’; // Your web service URL  $.ajax({    url: ajaxurl,      type: 'GET',      processData: false,      contentType: "application/json",      dataType: "jsonp",      success: function(data) {           $.mobile.changePage("results.html");     },       error: function() {           alert('Error!');     }   });

7. 从列表视图的链接中删除活动状态(jQuery Mobile)

$('div').live('pageshow', function (event, ui) {    $('[data-role=listview] li').removeClass("ui-btn-active"); });

8. 从下拉选择中禁用默认的jQuery Mobile样式(jQuery Mobile)

$(document).bind("mobileinit", function(){       $.mobile.page.prototype.options.keepNative = "select";   });

9. 动态更新列表视图(jQuery mobile)

var output  = '
';   output += '
' + item.title + '
';   output += '
';        $('#mylistul').append(output).listview('refresh');

10. 动态添加表单输入和应用默认样式(jQuery Mobile)

var html = '';   $('#searchform').append(html);   $('#suburb').textinput();
