Question

我将3个文件放在同一个文件夹中：jquery-1.10.2.js，info.xml和info.htm。

这是我的info.xml：

<Check>
    <Metainformation>
        <cash>ABC XYZ</cash>
        <Doctor>Dr. Peter Smith</Doctor>
        <DoctorID>12345678</DoctorID>
        <Quartal>Q22004</Quartal>
        <Checkdate>20040404123000</Checkdate>
    </Metainformation>
    <Patientlist>
        <Normal_Patient>
            <Unchanged count="123" />
            <New count="3" />
            <Closed count="2" />
            <InTest count="4" />
        </Normal_Patient>
        <Special_Patient>
            <Special_Quantity count="8" />
        </Special_Patient>
        <Notfound_Patient>
            <ABC_available count="9" />
            <DEF_available count="7" />
        </Notfound_Patient> 
        <Total old="125" new="126"/>
    </Patientlist>
</Check>

这是我的info.htm

<html>
<head>
<meta http-equiv=Content-Type content="text/html; charset=windows-1252">
<meta name="Daniel" content="Geneva">
<script language="JavaScript" type="text/javascript" src="jquery-1.10.2.js"></script>
<style type="text/css">
.frame {
    font-size: 10pt;
}
.div1 {
    margin-right:80px;
    margin-left:80px;
}
.table1 {
    width: 640px;
    margin: 0 auto;
    border-collapse: collapse;
    font-weight: bold;
}
.table1 td {
    vertical-align: top;
    padding-left: 6px;
    padding-bottom: 5px;
    border: 1px solid black;
    width: 320px;  
}
.table1 tr:nth-child(2) td {
    border: none;
}
</style>
</head>
<body>
<div class ='frame'>
    <div class='div1'>
        <table class='table1' style ='margin-top:20px'>
            <tr>
                <td>Contract</td>
                <td id="cash"> </td>
            </tr>
            <tr>
                <td>&nbsp;</td>
                <td>&nbsp;</td>
            </tr>
            <tr>
                <td>Doctor</td>
                <td id="Doctor"> </td>
            </tr>
            <tr>
                <td>Quartal</td>
                <td id="Quartal"> </td>
            </tr>
            <tr>
                <td>Test carried out by</td>
                <td id="Doctor1"></td>
            </tr>
            <tr>
                <td>Checkdate</td>
                <td id="Date"></td>
            </tr>
        </table>
    </div>
</div>

<script>
var xml = "info.xml";
xmlDoc = $.parseXML(xml);
$xml = $(xmlDoc);
$doctor = $xml.find("Doctor");
$id = $xml.find("DoctorID");
var doc = $doctor.text() + "(ID: " + $id.text() + ")";  
$("#Doctor").append(doc);
$("#Doctor1").append(doc);
</script>

</body>
</html>

我需要从Doctor加载DoctorID和info.xml，并将其放在字段Doctor和Doctor1中。但它不起作用。你能告诉我我在哪里错吗？

Answer 1

文件打开？

function doStuff() {
    return new Promise(function(resolve, reject) {
        // do asynchronous stuff
        var result = 100;
        resolve(result);
    });
}
doStuff.then(function(data) { console.log('Im done!', data); });

如果xml在变量中，则需要对其进行处理

function doStuff() {
    return new Promise(function(resolve, reject) {
        // do asynchronous stuff
        var result = 100;
        resolve(result);
    });
}
(async function() { // async/await only works in async functions.
    var data = await doStuff();
    console.log('Im done!', data);
})();

function fetchUserWithPosts(userId, callback) {
    fetchUser(userId, function(user) {
        fetchPostsByUserId(userId, function(posts) {
            callback({
                user: user,
                posts: posts
            });
        });
    });
}

parseXML不起作用
