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

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
Mozilla/5.0 (Linux; U; Android 2.2; en-gb; GT-P1000 Build/FROYO) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Mozilla/5.0 (Linux; U; Android 2.1-update1; de-de; E10i Build/2.0.2.A.0.24) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17

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();
}
<div data-role="page" id="home" ontouchmove="notouchmove(event);">
...
</div>

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('<div id="overlay" style="width: 100%; height:' + $(document).height() + 'px"><span style="top: ' + top + 'px">Landscape view is not supported for this page.</span></div>');
        }
    } 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 = '<span class="truncated">' + trunc;
        trunc += '<strong class="more-description">...</strong></span>';
        trunc += '<span class="original" style="display: none;">' + org + '</span>';
      }

      $('.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  = '<li><img src="' + item.image + '" alt="' + item.title + '" />';
output += '<h3><a href="' + item.url + '">' + item.title + '</a></h3>';
output += '</li>';    

$('#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 = '<input type="search" name="suburb" id="suburb" placeholder="Enter suburb" />';
$('#searchform').append(html);
$('#suburb').textinput();
