这段时间做了一个项目用到uploadifive上传控件，和uploadify不同，这个控件是基于HTML5的版本而不用支持falsh，因而移动端也可以使用。
整理用过的相关属性与方法：
| 属性 | 作用 |
| auto | 是否自动上传，默认true |
| uploadScript | 上传路径 |
| fileObjName | file文件对象名称 |
| buttonText | 上传按钮显示文本 |
| queueID | 进度条的显示位置 |
| fileType | 上传文件类型 |
| multi | 是否允许多个文件上传，默认为true |
| fileSizeLimit | 允许文件上传的最大尺寸 |
| uploadLimit | 一次可以上传的最大文件数 |
| queueSizeLimit | 允许队列中存在的最大文件数 |
| removeCompleted | 隐藏完成上传的文件，默认为false |
| 方法 | 作用 |
| onUploadComplete | 文件上传成功后执行 |
| onCancel | 文件被删除时触发 |
| onUpload | 开始上传队列时触发 |
| onFallback | HTML5 API不支持的浏览器触发 |
例子如下：
1.首先页面需要引进js和css文件
2.uploadifive控件的具体应用
$(function() {
$('#signup-idimage1').uploadifive({
'auto' : true,
'uploadScript' : 'uploadPhoto',
'fileObjName' : 'upload',
'buttonText' : '上传照片',
'queueID' : 'tip-queue1',
'fileType' : 'image/*',
'multi' : false,
'fileSizeLimit' : 5242880,
'uploadLimit' : 1,
'queueSizeLimit' : 1,
'onUploadComplete' : function(file, data) {
var obj = JSON.parse(data);
if (obj.img == "500") {
alert("系统异常！");
} else {
$("#frontSide").val(obj.img);
document.getElementById("submit").disabled = false;
}
},
onCancel : function(file) {
$("#frontSide").val("");
/* 注意：取消后应重新设置uploadLimit */
$data = $(this).data('uploadifive'),
settings = $data.settings;
settings.uploadLimit++;
alert(file.name + " 已取消上传~!");
},
onFallback : function() {
alert("该浏览器无法使用!");
},
onUpload : function(file) {
document.getElementById("submit").disabled = true;//当开始上传文件，要防止上传未完成而表单被提交
},
});
});
3.简化后的页面
<!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport"
content="width=device-width, initial-scale=1, maximum-scale=1">
<title>注册</title>
<link rel="stylesheet" type="text/css"
href="../uploadiFive/uploadifive.css" />
<script src="../js/jquery-1.7.2.js"></script>
<script src="js/mobileupload.js"></script>
<script src="../uploadiFive/jquery.uploadifive.js"></script>
</head>
<body>
<form class="cd-form" id="subForm"
action="openaccount" method="post">
<div id="cd-signup">
<p class="fieldset">
<label class="image-replace cd-photo1" for="signup-idimage1"></label>
<input class="full-width has-padding has-border"
id="signup-idimage1" type="file" name="upload">
<input type="hidden" name="frontSide" id="frontSide">
<div id="tip-queue1"></div>
</p>
</p>
<p class="fieldset">
<input class="full-width2" id="submit" type="submit" value="提交">
</p>
</form>
</body>
</html>
（IE9及以下不支持下面这些功能，其它浏览器最新版本均已支持。）
1、允许上传文件数量
允许选择多个文件：<input type="file" multiple>
只允许上传一个文件：<input type="file" single>
2、上传指定的文件格式
<input type="file" accept="image/gif,image/png" />
这里的上传格式仅指打开上传弹窗选择文件时默认的文件格式，可手动修改成其它文件格式。
如果不限制上传图片的格式可写成：accept="image/*"

这里要慎重说明的是：网上好多教程都说 excel过滤要用“accept="application/msexcel"” ，其实是大错特错！测试了，不行！ 我也是在做phpExcel导出excel文件是，看到了，有一行代码：
header(‘Content-Type: application/vnd.ms-excel‘); //excel 2003
header(‘Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘); //excel 2007
我才明白，原来 .xls 格式的文件，要用这个 MIME 类型。 测试，成功！
