首先抱歉，如果我有一些打字错误，英语不是我的主要语言，但我会尽力解释它。

我正在开发一个带有笔记数据库的测试应用程序。添加和删除它工作正常，但有一个小问题......目前，我添加注释(在 edit.html 上)并想要返回到 index.html 页面，但它不会返回。我正在使用多个数据页 Angular 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 header :

$("#homePage").live('pageinit', function() {
init();
});

index.html 数据页面 Angular 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" />
    <p>&copy; 2012 - Swen Kooij / Paksha Thullner / Johnny Jansen</p>
</div>
</div>

Edit.html(在这里您可以添加/更改/删除注释)

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);

    }
});
}

正如你在 saveNote 和 deleteNote 中看到的，我调用函数 window.navigator.location("index.html#homePage");我尝试使用 $.mobile.changePage("index.html#homePage"); 就做到了这一点它会返回，但不会运行 init();头脚本中的函数。我希望我的解释是正确的，如果有任何问题，请告诉我。然后我会尽力解释它。

首先感谢您的回答，我有多个数据 Angular 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" />
