Question

我遇到了问题，我需要将数据（id）从列表发送到另一个页面。这是html代码：

</head>
    <body>
        <div data-role="page" id="index">
            <div data-role="header">
                <h1>Players App</h1>
            </div><!--/header-->
            <div data-role="content">
                <ul data-role="listview" id="ul_list" data-inset="true">

                </ul>
            </div><!--/content-->
            <div data-role="footer">
                <h4>Players list</h4>
            </div><!--/footer-->
        </div><!--/page-index-->
        <div data-role="page" id="detail" data-add-back-btn="true">
            <div data-role="header">
                <h1>Player detail</h1>
            </div><!--/header-->
            <div data-role="content">
                <ul data-role="listview" id = "" data-inset="true">

                </ul>
            </div><!--/content-->
            <div data-role="footer">
                <h4>Players list</h4>
            </div><!--/footer-->
        </div><!--/page-detail-->
    </body>
</html>

这是脚本：

var lista = new Array();
var squadraManager={};

squadraManager.initArray=null;
squadraManager.printArray=null;

squadraManager.initArray = function(){
        lista[0] = new players();
        lista[0].setNome("Nonho");
        lista[0].setRuolo("difensore");
        lista[0].setCognome("Rossi");
        lista[0].setNMaglia("01");
        lista[1] = new players();
        lista[1].setNome("Marco");
        lista[1].setRuolo("blabla");
        lista[1].setCognome("Mariani");
        lista[1].setNMaglia("22");
        lista[2] = new players();
        lista[2].setNome("Carlo");
        lista[2].setRuolo("Soffiatore");
        lista[2].setCognome("Bianchi");
        lista[2].setNMaglia("01");
}
squadraManager.loaderList = function(){
    jQuery.each( lista, function(chiave, oggetto){
        //leggo valori oggetti in array 
            jQuery("#ul_list").append("<li><a id='"+ oggetto.getId() +"det' href='#dettaglio'>"+oggetto.getCognome()+"</a></li>").listview("refresh");
    });
}


squadraManager.init = function(){                             /*init */
    squadraManager.initArray();
    squadraManager.loaderList();
}
jQuery(function(){
    squadraManager.init();
});

我需要将点击列表的ID发送到下一页。最后的想法是加载第二页＆＃34;＃detail＆＃34;播放器的细节（播放器在一个单独的类中）。

Answer 1

一个HTML /多页面模板

以下是将一个属性从listview传递到1 html多页面模板中的第二页的示例：

http://jsfiddle.net/Gajotres/Gv7UW/ - js object as a storage container

http://jsfiddle.net/Gajotres/J9NTr/ - localStorage作为存储容器

基本上你要做的是为存储目的创建一个持久的javascript对象。只要ajax用于页面加载（并且页面不以任何方式重新加载），该对象将保持活动状态。

    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，所以我将发布所需的文件：

HTML 1：

<!DOCTYPE html>

<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>

        <div data-theme="a" data-role="footer" data-position="fixed">

operations.js：

$(document).on('pageshow', '#second', function(){   
    alert(getParameterByName("id"));
}); 


function getParameterByName(name) {
    return decodeURI(
        (RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
    );
}

使用jsFiddle示例无法显示的另一个示例，与之前的示例不同，此示例将附加SQL脚本。我建议你创建一个更好的数据库读取逻辑，这个是一个简单的解决方案，容易注入SQL，但它适用于你的任务：

index.php：

<!DOCTYPE html>
<html>

    <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>

    <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 data-role="page" id="index">
        <div data-theme="a" data-role="header">
            <h3></h3>
        </div>

        <div data-role="content">

        <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 : ""
}
