我有一个正在开发的简单黑莓应用程序，它使用 JSONP 和 Zepto.js。大多数代码都写得很快，我没有像我应该的那样使用 Zepto，但现在只需要测试它，我相信到目前为止我的所有代码都是有效的(JS 的新手 - 只是学习)。
index.html 示例
<!DOCTYPE html>

<td valign="middle" class="museo">

</div>
</div><!-- /header -->
<div data-role="content" class="content" id="list-wrapper">
<ul data-role="listview" id="servers" class="listview">
<li class="title-divider">Select a Subsonic Server</li>
</ul>
</div><!-- /content -->
</div><!-- /page -->
<script type="text/javascript" src="js/index.js"></script>
</body>
</html>
索引.js:
var db = window.openDatabase("bbsonic", "0.1", "SubSonic Server", 1024*1000);
$(document).ready = prepareDatabase();
function prepareDatabase() {
db.transaction(function(tx) {
var starterSQL = 'CREATE TABLE IF NOT EXISTS servers (id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(255) NOT NULL, url VARCHAR(255) NOT NULL, port VARCHAR(255) NOT NULL, user VARCHAR(255) NOT NULL, pass VARCHAR(255) NOT NULL)';
tx.executeSql(starterSQL, []);
});
showServerList();
}
function showServerList() {
db.transaction(function (tx) {
tx.executeSql('SELECT * FROM servers', [], function (tx, results) {
var len = results.rows.length, i;
for (i = 0; i < len; i++) {
var id = results.rows.item(i).id;
var name = results.rows.item(i).name;
var parent = document.getElementById('servers');
var listItem = document.createElement('a');
listItem.setAttribute('href', 'main.html');
listItem.setAttribute('onclick', 'setServerID(' + id + ')');
if (i == 0) {
listItem.innerHTML = '<li class="first-item">' + name + '</li>';
} else {
listItem.innerHTML = '<li>' + name + '</li>';
}
parent.appendChild(listItem);
}
var parent = document.getElementById('servers');
var listItem = document.createElement('a');
listItem.setAttribute('href','addnewserver.html');
listItem.innerHTML = "<li>Add New Server</li>";
parent.appendChild(listItem);
});
});
}
function setServerID(id) {
sessionStorage.serverID = id;
}

在 chrome 和 ripple 中，它工作得很好，但在黑莓上，它只加载标题，甚至不加载无序列表!甚至不知道如何去调试它...... 将不胜感激。
最佳答案
我不确定，但我认为您没有错误地使用某些 HTML 标记。通常如果你制作 <table> , 你嵌套一个 <tr>标记，然后嵌套 <td>标记在那里。例子
<table>
<tr>
<td><h1>BerrySonic</h1></td>
</tr>
</table>
我建议完全删除表格并只使用 <h1>直属<div id="header-logo"> . (除非 Zepto 出于某种非常奇怪的原因要求这样做。我对此并不熟悉)
另外，您的 java 脚本为您的列表创建了不正确的 HTML。就像表格一样，<ul>元素应该有 <li>嵌套在其中的元素。 showServerList()中的代码将创建如下所示的 HTML:
<a href="main.html"><li class="first-item">Server 1</li></a>
<a href="main.html"><li>Server 2</li></a>
当你真正需要的时候:
<li class="first-item"><a href="main.html">Server 1</a></li>
<li><a href="main.html">Server 2</a></li>
尝试进行这些更改，看看它是否能解决您的渲染问题。
关于javascript - WebWorks 应用程序根本无法运行，但可以在 Ripple 和 Chrome 以及 BB 浏览器中运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8920693/
