废话不多说了，直接给大家贴代码了，具体代码如下所示：
// 上传目标触发点
<input type="file" class="upvideo" name="upvideo" id="fileupload1" />
// 引入插件
<script type="text/javascript" src="{$IMG}/bstage/js/jquery.form.js" language="javascript"></script>
/**方法调用**/
setFileUpload({
name: 'fileupload1',
backfun: upback1,
beforefun: checkUp1,
loadfun:loadup,
phpUrl: '/ossphp/php/get.php?ft=video'
});
// 上传前验证
function checkUp1(n){
// 查看视频大小(mb)
var fileObj = document.getElementById(n).files[0];
var relSize = parseInt(fileObj.size/1024/1024);
if(relSize > 10){ // 大于10mb
alert('提示','视屏超过10MB,请重新上传！');
return false;
}
// 查看视频类型
var tv_id =document.getElementById(n).value;//根据id得到值
var index= tv_id.indexOf(".");
tv_id=tv_id.substring(index).toLowerCase();
if(tv_id!=".rb"&&tv_id!=".rmvb"&&tv_id!=".mp4"&&tv_id!=".flv"){
alert("提示","不是指定视频格式,重新选择");
return false;
}
return true;
}
//上传中
function loadup(){
}
// 上传成功后操作
function upback1(data){
// data 成功后的参数
}
/**上传功能封装**/
