php ajax上传组件。
PHP+Ajax上传文件[ajaxfileupload.js
可以批量进行添加上传，简单方便
<script type="text/javascript" src="jquery-1.5.1.min.js"></script>
<script
type="text/javascript" src="ajaxfileupload.js"></script>
<form id="upform" action="" method="post" enctype="multipart/form-data">
<input id='fname' size='80' /><br> <input type="file" name="file1"
id="file1" size="30" /> <input type="button" value="上传"
onclick="return ajaxFileUpload();" /> <span id="msg"
style="display: none">UpLoading...</span>
</form>
<script type="text/javascript">
var str = '';
function ajaxFileUpload(){
$("#msg")
.ajaxStart(function(){
$(this).show();
});
/*
.ajaxComplete(function(){
$(this).hide();
});
*/
$.ajaxFileUpload(
{
url:'up_deal.php',
secureuri:false,
fileElementId:'file1',
dataType: 'text',
//data:{name:'qinmi', id:'123'},
success: function(data){
if(data=='error'){
$('#msg').html("<span style='color:red'>上传失败</span>");
}else{
$('#msg').html("<span style='color:green'>上传成功</span>");
str += data+'@';
$('#fname').val(str);
}
}
}
);
return false;
}
</script>
up_deal.php
<?php
if ((($_FILES["file1"]["type"] == "image/gif")
|| ($_FILES["file1"]["type"] == "image/jpeg")
|| ($_FILES["file1"]["type"] == "image/bmp")
|| ($_FILES["file1"]["type"] == "image/pjpeg"))
&& ($_FILES["file1"]["size"] < 100000)){//100KB
$extend = explode(".",$_FILES["file1"]["name"]);
$key = count($extend)-1;
$ext = ".".$extend[$key];
$newfile = time().$ext;
if(!file_exists('upload')){mkdir('upload');}
move_uploaded_file($_FILES["file1"]["tmp_name"],"upload/" . $newfile);
@unlink($_FILES['file1']);
echo $newfile;
}else {
echo 'error';
}
?>
其中需要用到ajaxfileupload.js 这个文件，
