百度开源上传组件webuploader

//上传多文件

    function UploadMultiFile() {

        var uploader = WebUploader.create({

            // 内部根据当前运行是创建，可能是input元素，也可能是flash.

            // 不压缩image, 默认如果是jpeg，文件上传前会压缩一把再上传！

            resize: false

        });

        // 当有文件被添加进队列的时候

        uploader.on('fileQueued', function (file) {

            var itemTemplate = "";

            var fileSize = parseInt(file.size / 1024);

            if (fileSize >= 1024)

                    </div>'+ itemTemplate;

            $(".border").prepend(itemTemplate);

            $(".drag-tip").remove();

        });

        // 文件上传过程中创建进度条实时显示。

        uploader.on('uploadProgress', function (file, percentage) {

            var $li = $('#' + file.id),

                $percent = $li.find('.uploadify-progress .uploadify-progress-bar');

            // 避免重复创建

            if (!$percent.length) {

                $percent = $('<div class="uploadify-progress uploadify-progress-striped active">' +

        //文件成功、失败处理

        uploader.on('uploadSuccess', function (file) {

            $('#' + file.id).find('.data').text('  上传成功').css("color","green");

        });

                        </p>

                    </div>

                </div>

注意:使用Web Uploader文件上传需要引入三种资源：JS, CSS, SWF

<!--引入CSS-->

<link rel="stylesheet" type="text/css" href="webuploader文件夹/webuploader.css">

<!--引入JS-->

<script type="text/javascript" src="webuploader文件夹/webuploader.js"></script>

 

 补充上传成功后返回值的两方结合的问题：

        uploader.on('uploadSuccess', function (file, response) {

            if (response.type == 1 && response.errorcode == 0) {

                var arrData = [];

                var sort = 0;

                var inputValue = $("#fileData").val();

                if (inputValue != "") {

                    var jsonObj = JSON.parse(inputValue);

                    for (var i = 0; i < jsonObj.length; i++) {

                        sort = i + 1;

                        jsonObj[i]["SortCode"] = sort;

                        arrData.push(jsonObj[i]);

                    }

                }

                var newAdd = {};

                newAdd["FileName"] = file.name;

                newAdd["FilePath"] = response.message;

                newAdd["FileSize"] = parseInt(file.size / 1024);

                newAdd["FileExtensions"] = file.ext;

                newAdd["FileType"] = file.type;

                newAdd["SortCode"] =  sort + 1;

                arrData.push(newAdd);

                $("#fileData").val(JSON.stringify(arrData));

            }

        });
