起初很抱歉，如果我有一些打字错误，英语不是我的主要语言，但我会尽我所能解释它。
我正在开发一个带有笔记数据库的测试应用程序。添加和删除它可以正常工作，但有一个小问题......目前我添加了一个注释（在edit.html上）并想要返回到 index.html 页面它不会返回。我正在处理多个数据页面角色页面，因此每个页面都有自己的 ID。我用于笔记数据库的代码：
index.html 标题：
$("#homePage").live('pageinit', function() {
init();
});
index.html 数据页角色
<div data-role="page" id="homePage" data-add-back-btn="true" class="noteclass">
<!-- HEader -->
<div data-role="header" >
<h1>Notitie Database</h1>
</div>
<!-- Main content div -->
<div data-role="content" id="mainContent">
<ul data-role="listview" id="noteTitleList"></ul><br />
</div>
<div data-role="content">
<a href="edit.html" data-role="button" data-icon="plus">Voeg notitie toe</a>
</div>
<!-- Footer -->
<div data-role="footer" id="footer"> <img src="a12.png" />

这是我用于笔记数据库的后端代码
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
phoneready();
}
function setupTable(tx){
tx.executeSql("CREATE TABLE IF NOT EXISTS notes(id INTEGER PRIMARY KEY,title,body,updated)");
}
function getEntries() {
dbShell.transaction(function(tx)
{
tx.executeSql("select id,title,body, updated from notes order by id asc", dbErrorHandler, renderEntries)
}, function(){ alert ("Error getentries");
});
}
function renderEntries(tx,results){
if (results.rows.length == 0) {
$("#mainContent").html("<p>Je hebt nog geen notities.</p>");
} else {
var s = "";
for(var i=0; i<results.rows.length; i++) {
s += "<li><a href='edit.html?id="+results.rows.item(i).id + "'>" + results.rows.item(i).title + "</a></li>";
}
$("#noteTitleList").html(s);
$("#noteTitleList").listview("refresh");
}
}
function saveNote(note) {
//Sometimes you may want to jot down something quickly....
if(note.title == "") note.title = "[Geen Titel]";
dbShell.transaction(function(tx) {
if(note.id == "")
{
tx.executeSql("insert into notes(title,body,updated) values(?,?,?)",[note.title,note.body, new Date()]);
}
else
{
tx.executeSql("update notes set title=?, body=?, updated=? where id=?",[note.title,note.body, new Date(), note.id]);
}
}, function(){ alert ("Error savenote");},
function()
{
window.navigator.location("index.html#homePage");
});
}
function DeleteNote(id){
dbShell.transaction(
function(tx)
{
tx.executeSql('Delete FROM notes where id=' + id);
},
function(){ alert ("Error deletenote");},
function(err)
{
window.navigator.location("index.html#homePage");
});
}
function phoneready(){
dbShell = window.openDatabase("SimpleNotes", 2, "SimpleNotes", 1000000);
setupTable();
}
function init(){
getEntries();
//edit page logic needs to know to get old record (possible)
$("#editPage").live("pagebeforeshow", function() {
//get the location - it is a hash - got to be a better way
var loc = window.location.hash;
if(loc.indexOf("?") >= 0) {
var qs = loc.substr(loc.indexOf("?")+1,loc.length);
var noteId = qs.split("=")[1];
//load the values
dbShell.transaction(
function(tx) {
tx.executeSql("select id,title,body from notes where id=?",[noteId],function(tx,results) {
$("#noteId").val(results.rows.item(0).id);
$("#noteTitle").val(results.rows.item(0).title);
$("#noteBody").val(results.rows.item(0).body);
});
}, dbErrorHandler);
}
});
}
正如您在 saveNote 和 deleteNote 上看到的那样，我调用函数 window.navigator.location("index.html#homePage"); 我尝试使用 $.mobile.changePage("index.html#homePage"); 它会返回，但不会运行 init(); 头脚本中的函数。我希望我解释的一切都是正确的，如果有任何问题，请告诉我。然后我会尽力解释它。
编辑：更多信息：
首先感谢您的回答，我得到了多个数据角色页面。
一个额外的例子：
<div data-role="page" id="page5" data-add-back-btn="true">
<!-- Header -->
<div data-role="header" >
<h1>Locatie</h1>
</div>
<!-- Main content div -->
<div data-role="content">
<p id="geolocation" onClick="onDeviceReady()">Op zoek naar uw locatie ...</p>
<img src="" id="map" width="100%" height="" />
<h4>Omgeving</h4>
<img src="" id="map2" width="100%" height="" />
</div>
<div data-role="footer" id="footer"> <img src="a12.png" />
