jquery+php+ajax显示上传进度的多图片上传并生成缩略图代码

本例用到其他2个php class.upload.php和 functions.php还有css和js以及img文件

完整实例代码点击此处本站下载。

效果图如下：

实现代码如下：

JavaScript代码如下：

<script type="text/javascript">  

$(document).ready(function() {  

    $("#filelist").niceScroll({  

        cursorwidth: "8px",  

        cursorborderradius: "0px",  

        cursoropacitymin: 0.1,  

        cursoropacitymax: 0.3  

    });  

  

    $(".side-pane").niceScroll({  

        cursorwidth: "8px",  

        cursorborderradius: "0px",  

        cursoropacitymin: 0.1,  

        cursoropacitymax: 0.3  

    });  

  

    $(".time").timeago();  

});  

</script>
 

javascript代码如下：

<script type="text/javascript">  

        // <![CDATA[

上面2个js都放在index.php里面

XML/HTML代码如下：

            <div id="filelist"></div>  

  

            <div class="action-btns">  

                <a id="pickfiles" class="login-button btn">Select files to upload</a>  

                <a href="javascript:;" id="upload_button" class="login-button upload hide">Upload</a>  

            </div>  

  

            <center>  

                <div id="upload_info">  

                    <div id="upload_info_inner">  

                        <div class="progressbg">  

                            <div id="percent" class="progress"></div>  

                        </div>  

                    </div>  

  

                    <div id="unknown">  

                        <div id="time2go"></div>  

                        <div id="upRate"></div>
