我制作了一个简单的cordova测试应用程序来测试运行媒体捕获插件,单击录制音频、捕获图像或录制视频的按钮没有任何反应

以下是我在 cordova 项目目录中安装的插件: 在此处输入图像描述

以下是 HTML 文件的代码

 <button id = "audioCapture">AUDIO</button>
 <button id = "imageCapture">IMAGE</button>
 <button id = "videoCapture">VIDEO</button>

以下是 JS 文件的代码,我在其中分别添加了音频捕获、图像捕获和视频捕获的功能。

document.getElementById("audioCapture").addEventListener("click", audioCapture);
document.getElementById("imageCapture").addEventListener("click", imageCapture);
document.getElementById("videoCapture").addEventListener("click", videoCapture);
function audioCapture() {
    var options = {
        limit: 1,
        duration: 10
    };
    navigator.device.capture.captureAudio(onSuccess, onError, options);

    function onSuccess(mediaFiles) {
        var i, path, len;
        for (i = 0, len = mediaFiles.length; i < len; i += 1) {
            path = mediaFiles[i].fullPath;

        }
    }

    function onError(error) {
        navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
    }
}

function imageCapture() {
    var options = {
        limit: 1
    };
    navigator.device.capture.captureImage(onSuccess, onError, options);

    function onSuccess(mediaFiles) {
        var i, path, len;
        for (i = 0, len = mediaFiles.length; i < len; i += 1) {
            path = mediaFiles[i].fullPath;

        }
    }

    function onError(error) {
        navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
    }
}

function videoCapture() {
    var options = {
        limit: 1,
        duration: 10
    };
    navigator.device.capture.captureVideo(onSuccess, onError, options);

    function onSuccess(mediaFiles) {
        var i, path, len;
        for (i = 0, len = mediaFiles.length; i < len; i += 1) {
            path = mediaFiles[i].fullPath;

        }
    }

    function onError(error) {
        navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
    }
}

Cordova 必须完全加载才能使用设备 API

为此,cordova 提供了 deviceready 事件

在 HTML 正文中添加onload功能

<body onload="onLoad()">

在 JS 中

function onLoad() {
  document.addEventListener("deviceready", onDeviceReady, false);
}

// ready to use device APIs
function onDeviceReady() {
   console.log(navigator.device);
   // document.getElementById("audioCapture").addEventListener("click", audioCapture);
}
