Question

我一直试图找出为什么在单击图像时相机无法启动，这使得它成为一个按钮。即使尝试重新安装cordova相机插件，错误仍然存在。请帮助......

function onDeviceReady() { <<<------ JS File 
        $("#photo1").click(Camera1);
        detection();
    }
    function Camera1() {
        navigator.camera.getPicture(onSuccess, onFail, {
            quality: 50,
            destinationType: Camera.DestinationType.DATA_URL,
            sourceType: Camera.PictureSourceType.CAMERA,
            encodingType: Camera.EncodingType.JPEG,
            targetWidth: 300,
            targetHeight: 300,
            popoverOptions: CameraPopoverOptions,
            saveToPhotoAlbum: true
        });
        function onSuccess(imageData) {
            var image = document.getElementById('myImage');
            image.src = "data:image/jpeg;base64," + imageData;
        }
        function onFail(message) {
            $("#errormsg").text("ERROR");
        }
    };

        });

可能的解决方案是，

离线下载JQuery，而不是在CDN上加载（由于加载时间不正确，可能会发生错误）
确保您正在验证JQuery ready +设备就绪事件
检查您的相机访问权限

Cordova相机应用程序未启动
