请帮忙！如何通过“#btn_2”点击获取我手机的经纬度？对于 index.html：

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="css/bootstrap.css">
    <link rel="stylesheet" type="text/css" href="css/index.css">
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/jquery.js"></script>
    <script type="text/javascript" src="js/bootstrap.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
</head>
<body onload="Ready()">
    <div class=".app">
        <form style="padding: 15px" id="form_1" name="form_1">
            <br>
            <button type="Submit" id="btn_2">geo location</button>
        </form>
        <span id="result"></span>
    </div>
</body>
</html>

对于 index.js：

function Ready()
document.addEventListener("deviceready", onDeviceReady, false);


function onDeviceReady()
$(document).ready(function()
    $('#btn_2').click(function()
        navigator.geolocation.getCurrentPosition(onSuccess, onError,  
timeout: 5000, enableHighAccuracy: true );
    );
);

var onSuccess = function(position) 
    alert('Latitude: '          + position.coords.latitude          + '\n' +
          'Longitude: '         + position.coords.longitude         + '\n' +
          'Altitude: '          + position.coords.altitude          + '\n' +
          'Accuracy: '          + position.coords.accuracy          + '\n' +
          'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
          'Heading: '           + position.coords.heading           + '\n' +
          'Speed: '             + position.coords.speed             + '\n' +
          'Timestamp: '         + position.timestamp                + '\n');
;

function onError(error) 
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');

当尝试点击我手机中的按钮时，它没有显示任何警报，既没有成功也没有错误警报。请帮忙！

【参考方案1】：

当您按下按钮时，它会提交您的表单“form_1”，并且可能会重新加载页面。这可能是一个原因。尝试将按钮移出表单，或添加另一个不带 type="submit" 的按钮。

当您第一次尝试检查地理位置时，系统可能会询问您的权限。检查你是否没有否认我的错误。

您也可以尝试重新安装地理定位插件

cordova plugin add cordova-plugin-geolocation

这是我的工作代码

<div class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
            <button id="geo-button" class="button">Geo</div>
        </div>
    </div>
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script>

index.js

var app = 
// Application Constructor
initialize: function() 
    document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
,

// deviceready Event Handler
//
// Bind any cordova events here. Common events are:
// 'pause', 'resume', etc.
onDeviceReady: function() 
    this.receivedEvent('deviceready');
,

// Update DOM on a Received Event
receivedEvent: function(id) 
    var parentElement = document.getElementById(id);
    var listeningElement = parentElement.querySelector('.listening');
    var receivedElement = parentElement.querySelector('.received');

    listeningElement.setAttribute('style', 'display:none;');
    receivedElement.setAttribute('style', 'display:block;');

    console.log('Received Event: ' + id);

    const geoButton = document.getElementById('geo-button');

    geoButton.addEventListener('click', function(e) 
        navigator.geolocation.getCurrentPosition(function(position) 
            alert('Latitude: '          + position.coords.latitude          + '\n' +
              'Longitude: '         + position.coords.longitude         + '\n' +
              'Altitude: '          + position.coords.altitude          + '\n' +
              'Accuracy: '          + position.coords.accuracy          + '\n' +
              'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
              'Heading: '           + position.coords.heading           + '\n' +
              'Speed: '             + position.coords.speed             + '\n' +
              'Timestamp: '         + position.timestamp                + '\n');
        , function onError(error) 
            alert('code: '    + error.code    + '\n' +
                'message: ' + error.message + '\n');
        );
    );

别忘了为 ios 添加它

<edit-config file="*-Info.plist" mode="merge" target="NSLocationWhenInUseUsageDescription">
    <string>need location access to find things nearby</string>
</edit-config>
