Ajax单文件上传
html代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>单文件上传</title>
</head>
<body>
<label>请选择需要上传的文件：</label>
<input type="file" name="simpleFile" id="simpleFile" />
<button id="btn">上传</button>
<script>
document.getElementById('btn').onclick=function(){
if(window.XMLHttpRequest){
var xhr = new XMLHttpRequest();
} else {
var xhr = new ActiveXObject('Microsoft XMLHTTP');
}
xhr.open('POST','http://localhost/demo/input1/file.php','true');
xhr.setRequestHeader('X-Requested-With','XMLHttpRequest');
var formData = new FormData();
formData.append('file',document.getElementById('simpleFile').files[0]);
xhr.send(formData);
xhr.onreadystatechange=function(){
if(xhr.readyState===4){
if(xhr.status===200){
console.log('文件发送成功'+xhr.responseText);
} else {
alert('ERROR:'+xhr.status);
}
}
}
}
</script>
</body>
</html>
php代码如下：
<?php

//echo $mac->mac_addr;
//-------------------------------------------------------
$dir = iconv('UTF-8','GBK','uploads');
if(!file_exists($dir)){

}
?>
结果：
