我目前正在使用PhoneGap,由于某种原因,当我单击一个按钮时,该功能未定义。iv 尝试将它放在 deviceReady 函数以及文档就绪函数中,但似乎都没有任何区别。
我看不出问题出在哪里,如果有人可以提供帮助,那就太好了。

我的 JavaScript/jQuery:
document.addEventListener("deviceready", onDeviceReady, false);
var platform;
function onDeviceReady() {
//Find out what platform the device is running
platform = device.platform;
//Camera Section
function retrievePicture() {
// Take a picture using device camera and retrieve image
//navigator.camera.getPicture(onCaptureSuccess, onCaptureFail, {Camera.sourceType = Camera.PictureSourceType.PHOTOLIBRARY});
$('#pictureStatus').text("hello");
}
function onCaptureSuccess(imageData) {
$('#capturedImage').css("display", "block");
var imageLocation = imageData;
$('#capturedImage').attr("src", imageLocation);
$('#pictureStatus').text(imageLocation);
}
function onCaptureFail(message) {
$('#pictureStatus').text(message);
}
}
