一个 HTML / 多页模板
这是一个在 1 html 多页模板中将属性从 listview 传递到第二页的示例：
http://jsfiddle.net/Gajotres/Gv7UW/ - js对象作为存储容器
http://jsfiddle.net/Gajotres/J9NTr/ - localStorage 作为存储容器
基本上你想要做的是创建一个持久的 javascript 对象用于存储目的。只要 ajax 用于页面加载（并且页面不会以任何方式重新加载），该对象就会保持活动状态。
var storeObject = {
firstname : '',
lastname : ''
}
多个 HTML 页面模板
不幸的是，这个例子不能通过 jsFiddle 完成，所以我将发布需要的文件：
HTML 1：
<!DOCTYPE html>
<html>
<head>
<title>jQM Complex Demo</title>
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script src="operations.js"></script>
</head>
<body>
<div data-role="page" id="index">
<div data-theme="a" data-role="header">
<h3>
First Page
</h3>
<a href="#second" class="ui-btn-right">Next</a>
</div>
<div data-role="content">
<ul data-role="listview" data-theme="a" id="test-listview">
<li><a href="page2.html?id=1">Link 1</a></li>
<li><a href="page2.html?id=2">Link 2</a></li>
<li><a href="page2.html?id=3">Link 3</a></li>
<li><a href="page2.html?id=4">Link 4</a></li>
<li><a href="page2.html?id=5">Link 5</a></li>
</ul>
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
</div>
</div>
</body>
</html>
HTML 2：
<!DOCTYPE html>
<html>
<head>
<title>jQM Complex Demo</title>
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<div data-role="page" id="second">
<div data-theme="a" data-role="header">
<h3>
Second Page
</h3>
<a href="#index" class="ui-btn-left">Back</a>
</div>
<div data-role="content">
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
</div>
</div>
</body>
</html>
操作.js：
$(document).on('pageshow', '#second', function(){
alert(getParameterByName("id"));
});
function getParameterByName(name) {
return decodeURI(
(RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
);
}
用户认证演示
另一个无法使用 jsFiddle 示例显示的示例，与之前的示例不同，此示例将附加 SQL 脚本。我会建议你创建一个更好的数据库读取逻辑，这是一个简单的解决方案，容易发生 SQL 注入，但它对你的分配很有效：
index.php：
<!DOCTYPE html>
<html>
<head>
<title>jQM Complex Demo</title>
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<style>
#login-button {
margin-top: 30px;
}
</style>
<script src="http://www.dragan-gaic.info/js/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script src="js/custom.js"></script>
</head>
<body>
<div data-role="page" id="login">
<div data-theme="a" data-role="header">
<h3>Login Page</h3>
</div>
<div data-role="content">
<label for="username">Enter your username:</label>
<input type="text" value="" name="username" id="username"/>
<label for="password">Enter your password:</label>
<input type="password" value="" name="password" id="password"/>
<a data-role="button" id="login-button" data-theme="b">Login</a>
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
</div>
</div>
<div data-role="page" id="index">
<div data-theme="a" data-role="header">
<h3></h3>
</div>
<div data-role="content">
Here goes content
</div>
<div data-theme="a" data-role="footer" data-position="fixed">
<h3>Page footer</h3>
</div>
</div>
</body>
</html>
json.php：
<?php
$var1 = $_REQUEST['action']; // We dont need action for this tutorial, but in a complex code you need a way to determine ajax action nature
$jsonObject = json_decode($_REQUEST['outputJSON']); // Decode JSON object into readable PHP object
$username = $jsonObject->{'username'}; // Get username from object
$password = $jsonObject->{'password'}; // Get password from object
mysql_connect("localhost","root",""); // Conect to mysql, first parameter is location, second is mysql username and a third one is a mysql password
@mysql_select_db("test") or die( "Unable to select database"); // Connect to database called test
$query = "SELECT * FROM users WHERE user_name = '".$username."' and user_pass = '".$password."'";
$result=mysql_query($query);
$num = mysql_numrows($result);
if($num != 0) {
echo "true";
} else {
echo "false";
}
?>
custom.js：
$(document).on('pagebeforeshow', '#login', function(){
$('#login-button').on('click', function(){
if($('#username').val().length > 0 && $('#password').val().length > 0){
userObject.username = $('#username').val(); // Put username into the object
userObject.password = $('#password').val(); // Put password into the object
// Convert an userObject to a JSON string representation
var outputJSON = JSON.stringify(userObject);
// Send data to server through ajax call
// action is functionality we want to call and outputJSON is our data
ajax.sendRequest({action : 'login', outputJSON : outputJSON});
} else {
alert('Please fill all nececery fields');
}
});
});
$(document).on('pagebeforeshow', '#index', function(){
if(userObject.username.length == 0){ // If username is not set (lets say after force page refresh) get us back to the login page
$.mobile.changePage( "#login", { transition: "slide"} ); // In case result is true change page to Index
}
$(this).find('[data-role="header"] h3').append('Wellcome ' + userObject.username); // Change header with wellcome msg
//$("#index").trigger('pagecreate');
});
// This will be an ajax function set
var ajax = {
sendRequest:function(save_data){
$.ajax({url: 'http://localhost/JSONP_Tutorial/json.php',
data: save_data,
async: true,
beforeSend: function() {
// This callback function will trigger before data is sent
$.mobile.showPageLoadingMsg(true); // This will show ajax spinner
},
complete: function() {
// This callback function will trigger on data sent/received complete
$.mobile.hidePageLoadingMsg(); // This will hide ajax spinner
},
success: function (result) {
if(result == "true") {
$.mobile.changePage( "#index", { transition: "slide"} ); // In case result is true change page to Index
} else {
alert('Login unsuccessful, please try again!'); // In case result is false throw an error
}
// This callback function will trigger on successful action
},
error: function (request,error) {
// This callback function will trigger on unsuccessful action
alert('Network error has occurred please try again!');
}
});
}
}
// We will use this object to store username and password before we serialize it and send to server. This part can be done in numerous ways but I like this approach because it is simple
var userObject = {
username : "",
password : ""
}
