在我的 phonegap 应用程序中,我更新了我的数据,因为我有以下代码,因为我得到了 window.location.hash(* 指示错误行)值将为空。

function init() {

$("#homePage").live("pageshow", function() {
getDatas();
});

$("#editPage").live("pageshow", function() {
***var loc = window.location.hash;***
alert("loc" + loc);
if(loc.indexOf("?") >= 0) {
var qs = loc.substr(loc.indexOf("?")+1, loc.length);
var detailId = qs.split("=")[1];
$("#editFormSubmitButton").attr("disabled", "disabled");
dbShell.transaction(function(tx) {
tx.executeSql("select id,name,age,city,occupation from nameDetail where id=?", [detailId], function(tx, results) {
$("#mId").val(results.rows.item(0).id);
$("#mName").val(results.rows.item(0).name);
$("#mAge").val(results.rows.item(0).age);
$("#mCity").val(results.rows.item(0).city);
$("#mOccupation").val(results.rows.item(0).occupation);
$("#editFormSubmitButton").removeAttr("disabled");
});
}, dbErrHandler);
} else {
alert("empty");
$("#editFormSubmitButton").removeAttr("disabled");
}
});

}

function getDatas() {
dbShell.transaction(function(tx) {
tx.executeSql("select id,name,age,city,occupation,date from nameDetail order by date desc", [], renderEntries, dbErrHandler);
}, dbErrHandler);
}

function renderEntries(tx, results) {
if (results.rows.length == 0) {
$("#mainContent").html("<p>Don't have any Details</p>");
} else {
var s = "";
for (var i = 0; i < results.rows.length; i++) {
s += "<li><a href='addEdit.html?id="+results.rows.item(i).id + "'>" +results.rows.item(i).name + "</a></li>";
alert("" + s);
}
//alert(S);
$("#noteTitleList").html(s);
$("#noteTitleList").listview("refresh");
}
}

索引.html:

<body onload="init();">

<div data-role="header">

</div>

<div data-role="content" id="mainContent">
<ul data-role="listview" id="noteTitleList"></ul>
</div>

<div data-role="footer" class="ui-bar">
<a href="addEdit.html" data-role="button" data-icon="plus">Add Note</a>
</div>

</div>

</body>
</html>

和 addEdit.html:

<div data-role="page" id="editPage">

<div data-role="header">
<h1>Details</h1>
</div>

<div data-role="content">
<form id="addEditForm" method="post">
<input type="hidden" name="mId" id="mId" value="">
<div data-role="fieldcontain">
<label for="mName">Name</label>
<input type="text" name="mName" id="mName"/>
</div>
<div data-role="fieldcontain">
<label for="mAge">Age</label>
<input name="mAge" id="mAge"/>
</div>
<div data-role="fieldcontain">
<label for="mCity">City</label>
<input name="mCity" id="mCity"/>
</div>
<div data-role="fieldcontain">
<label for="mOccupation">Occupation</label>
<input name="mOccupation" id="mOccupation"/>
</div>
<div data-role="fieldcontain">
<input type="submit" id="editFormSubmitButton" value="Save Note">
</div>
</form>
</div>

<div data-role="footer" class="ui-bar">
<a href="index.html" data-role="button" data-icon="home">Return Home</a>
<input type="button" data-role="button" id="sync" name="sync" value="Sync" data-icon="arrow-d"/>
</div>

</div>

如何解决这个一些 body 帮助解决这个......

编辑:

问题用这个解决了。 solution link

最佳答案

我用下面的方法得到了解决方案

var loc = $(location).attr('href');
if (loc.indexOf("?") >= 0) {
var url = loc.substr(loc.indexOf("?") + 1, loc.length);
listId = url.split("=")[1];

这对像我这样的人会有帮助。
