我面临的问题在这里,因为在你选择一个图片时,手机图像被上传到服务器.我不想在提交表单之前上传图像.图像自动上传到服务器,这是我不想要的东西.我想使用表单上传图像,其中表单包含更多的字段,这些字段与图像一起发送.用表单提交的可能方式是什么？

function getImage() {
// Retrieve image file location from specified source
navigator.camera.getPicture(uploadPhoto,function(message) {

解决方法
创建两个可以单独调用的功能.一个功能只是获取图像,另一个功能上传图像.
你可以做下面的事情.
<!DOCTYPE html>
<html>
<head>
<title>Submit form</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
var pictureSource; // picture source
var destinationType; // sets the format of returned value
// Wait for device API libraries to load
//
document.addEventListener("deviceready",false);
// device APIs are available
//
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
// Show the selected image
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
smallImage.src = imageURI;
}
// A button will call this function
//
function getPhoto(source) {
// Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess,onFail,{ quality: 50,destinationType: destinationType.FILE_URI,sourceType: source });
}
function uploadPhoto() {
//selected photo URI is in the src attribute (we set this on getPhoto)
var imageURI = document.getElementById('smallImage').getAttribute("src");
if (!imageURI) {
alert('Please select an image first.');
return;
}
//set upload options
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType = "image/jpeg";
options.params = {
firstname: document.getElementById("firstname").value,lastname: document.getElementById("lastname").value,workplace: document.getElementById("workplace").value
}
var ft = new FileTransfer();
ft.upload(imageURI,encodeURI("http://some.server.com/upload.PHP"),options);
}
// Called if something bad happens.
//
function onFail(message) {
console.log('Failed because: ' + message);
}
function win(r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
//alert("Response =" + r.response);
console.log("Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
</script>
</head>
<body>
<form id="regform">
<button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">Select Photo:</button><br>
