2. jquery file upload 样式

使用了bootstrap框架，样式可以参考Demo。

自定义的样式：

<div class="row fileupload-buttonbar" style="padding-left:15px;">
<div class="thumbnail col-sm-6">
<img id="weixin_show" style="height:180px;margin-top:10px;margin-bottom:8px;"  src="__PUBLIC__/images/game/game_1.png" data-holder-rendered="true">
<div class="progress progress-striped active" role="progressbar" aria-valuemin="10" aria-valuemax="100" aria-valuenow="0"><div id="weixin_progress" class="progress-bar progress-bar-success" style="width:0%;"></div></div>
<div class="caption" align="center">
<span id="weixin_upload" class="btn btn-primary fileinput-button">
<span>上传</span>
<input type="file" id="weixin_image" name="weixin_image" multiple>
</span>
<a id="weixin_cancle" href="javascript:void(0)" class="btn btn-warning" role="button" onclick="cancleUpload('weixin')" style="display:none">删除</a>
</div>
</div>
</div>

    <link href="__PUBLIC__/css/bootstrap.min.css" rel="stylesheet">
    <!-- CSS to style the file input field as button and adjust the Bootstrap progress bars -->
    <link rel="stylesheet" href="__PUBLIC__/css/jquery.fileupload.css">
    <link rel="stylesheet" href="__PUBLIC__/css/jquery.fileupload-ui.css">
    <script src="__PUBLIC__/js/jquery.min.js"></script>
    <script src="__PUBLIC__/js/vendor/jquery.ui.widget.js"></script>
    <script src="__PUBLIC__/js/jquery.fileupload.js"></script>
    <script src="__PUBLIC__/js/jquery.iframe-transport.js"></script>

$(function() {
	$("#weixin_image").fileupload({
	    	url: '__CONTROLLER__/uploadImg',
	    	sequentialUploads: true
	    }).bind('fileuploadprogress', function (e, data) {
	    	var progress = parseInt(data.loaded / data.total * 100, 10);
	    	$("#weixin_progress").css('width',progress + '%');
	    	$("#weixin_progress").html(progress + '%');
	    }).bind('fileuploaddone', function (e, data) {
	    	$("#weixin_show").attr("src","__PUBLIC__/"+data.result);
	    	$("#weixin_upload").css({display:"none"});
	    	$("#weixin_cancle").css({display:""});
	    });
		   
	});

fileuploadprogress：主要是进度条的修改

fileuploaddone：上传结束后执行的操作

3. 后台执行的代码

使用的thinkphp代码，上传代码很简单

public function uploadImg(){

        $upload = new \Think\Upload();// 实例化上传类
        $upload->maxSize   =     3145728 ;// 设置附件上传大小
        //$upload->exts      =     array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型
        $upload->rootPath  =      './Public/Uploads/'; // 设置附件上传根目录
        $upload->savePath  =      ''; // 设置附件上传（子）目录
        
        // 上传文件 
        $info   =   $upload->uploadOne($_FILES['weixin_image']);
        if(!$info) {// 上传错误提示错误信息
            //$this->error($upload->getError());
            echo 0;
        }else{// 上传成功 获取上传文件信息
            //$this->display('templateList');
            echo "Uploads/".$info['savepath'].$info['savename'];
        }
    }
