Question

我能够使用Missing Manual系列JavaScript版本提供的示例非常有帮助！

OG.Q。 我看了一下尝试了几种不同的方法，但一直未能找到解决方案。

我正在尝试做什么。

将用户输入保存在sglite数据库中，已完成..
将sqlite数据检索为javascript变量，我认为这是我的问题。
使用变量作为ajaxURL来检索json，或者这可能是错误的。

的Javascript

<script>

$(document).ready(function() {
    var db = openDatabase ("Test", "1.0", "Test", 65535);
    $db.transaction (function (transaction) 
    {
        var sql = "SELECT * FROM scprofiles";
        transaction.executeSql (sql, undefined, 
        function (transaction, result)
        { 
             //I think this is the problem host, id and name are stored in sqlite

            var URL = "http://" + host + "/web/" + id + "/1/" + name + "/";
            var jsonFormat = "?format=json&callback=?";   
            var ajaxURL = URL + jsonFormat;
            $.getJSON(ajaxURL,function(data) {
                $('h1').text(data.displayName);
                $('#stuff').text(data.user.info); 
            });
        }error);
    });
}); //db.transaction

function ok ()
{
}

function error (transaction, err) 
{
    alert ("DB error : " + err.message);
    return false;
} 
}); // end ready
</script>

然后是html

<div class="content">
    <div class="main">
        <h1>JSON Data</h1>
        <div id="stuff"></div>
        <br class="clearLeft">
    </div>
</div>

非常感谢任何建议！
