UPDATE CODE BELOW
更新下面的代码
I found some code that is able to upload an image and display its thumbnail. However, I would like to save the images to a particular folder as well.
我找到了一些能够上传图像并显示其缩略图的代码。但是,我想将图像保存到特定文件夹中。
What jQuery code or ajax code can I use to save the original image to a folder of my choice?

UPDATE: I think I am on the right track. I am close but I don't know what data to send from the jQuery. I added a php scrit and its getting a call back as success but I am not sending the right var. I think if I just send the right val I can get it. CODE:
更新:我认为我走在正确的轨道上。我很接近,但我不知道从jQuery发送什么数据。我添加了一个php scrit,它的回调成功,但我没有发送正确的var。我想如果我发送正确的val我就可以得到它。码:
<script>
$( document ).ready(function() {
function readURL(input, target) {
if (input.files && input.files[0]) {
var reader = new FileReader();
var image_target = $(target);
reader.onload = function (e) {
image_target.attr('src', e.target.result).show();
$.ajax({
type:'POST',
url: 'theUpload.php',
data: input.files[0],
success:function(data){
console.log("success");
console.log(data);
alert(data);
},
error: function(data){
console.log("error");
console.log(data);
}
});
};
reader.readAsDataURL(input.files[0]);
}
}
$("#patient_pic").live("change",function(){
readURL(this, "#preview_image")
});
});
</script>

Try this one.
试试这个。
Script:
脚本:
function uploadFile(){
var input = document.getElementById("file");
file = input.files[0];
if(file != undefined){
formData= new FormData();
if(!!file.type.match(/image.*/)){
formData.append("image", file);
$.ajax({
url: "upload.php",
type: "POST",
data: formData,
processData: false,
contentType: false,
success: function(data){
alert('success');
}
});
}else{
alert('Not a valid image!');
}
}else{
alert('Input something!');
}
}

<button onclick="uploadFile();">Upload</button>

upload.php:
upload.php的:
<?php
$dir = "image/";
move_uploaded_file($_FILES["image"]["tmp_name"], $dir. $_FILES["image"]["name"]);
?>

You need a server side language to store the uploaded image to specified folder. PHP is one of them, so I highly recommend to take a look of it.
您需要一种服务器端语言来将上载的图像存储到指定的文件夹。 PHP就是其中之一,所以我强烈建议你去看看它。
AJAX is just for executing server side calls without refreshing the page.
AJAX仅用于在不刷新页面的情况下执行服务器端调用。

John's answer is good but file = input.files[0] doesn't work for me
John的答案很好但是file = input.files [0]对我不起作用
file = input[0].files[0]
works.
作品。
