Uploadify3.2中文提示

官网地址：http://www.uploadify.com

Uploadify是一款基于Jquery的上传插件，用起来很方便。但上传过程中的提示语言为英文，这里整理下如何修改英文为中文提示。

方法1：直接修改uploadify.js中的提示信息，将英文提示改成对应的中文。不过从软件设计的角度来说，直接修改原类库不是最好的解决方案，会影响到软件的升级。

方法2：重写Uploadify事件'overrideEvents' : [ 'onDialogClose', 'onUploadError', 'onSelectError' ]当重写onDialogClose事件后，Uploadify的错误提示信息就都不会提示了。提示信息可直接自定义弹出。

重写事件errorCode的定义在js库中都可以找到。也可以直接用this.queueData.errorMsg来改变提示信息

var uploadify_onSelectError = function(file, errorCode, errorMsg) { 
    var msgText = "上传失败n"; 
    switch (errorCode) { 
        case SWFUpload.QUEUE_ERROR.QUEUE_LIMIT_EXCEEDED: 
            this.queueData.errorMsg = "每次最多上传 " + this.settings.queueSizeLimit + "个文件"; 
            msgText += "每次最多上传 " + this.settings.queueSizeLimit + "个文件"; 
            break; 
        case SWFUpload.QUEUE_ERROR.FILE_EXCEEDS_SIZE_LIMIT: 
            msgText += "文件大小超过限制( " + this.settings.fileSizeLimit + " )"; 
            break; 
        case SWFUpload.QUEUE_ERROR.ZERO_BYTE_FILE: 
            msgText += "文件大小为0"; 
            break; 
        case SWFUpload.QUEUE_ERROR.INVALID_FILETYPE: 
            msgText += "文件格式不正确，仅限 " + this.settings.fileTypeExts;
            break; 
        default: 
            msgText += "错误代码：" + errorCode + "n" + errorMsg; 
    } 
    alert(msgText); 
}; 
var uploadify_onUploadError = function(file, errorCode, errorMsg, errorString) { // 手工取消不弹出提示 
    if (errorCode == SWFUpload.UPLOAD_ERROR.FILE_CANCELLED || errorCode == SWFUpload.UPLOAD_ERROR.UPLOAD_STOPPED) { 
        return; 
    } 
    var msgText = "上传失败n"; 
    switch (errorCode) { 
        case SWFUpload.UPLOAD_ERROR.HTTP_ERROR: 
            msgText += "HTTP 错误n" + errorMsg; 
            break; 
        case SWFUpload.UPLOAD_ERROR.MISSING_UPLOAD_URL: 
            msgText += "上传文件丢失，请重新上传"; 
            break;
        case SWFUpload.UPLOAD_ERROR.IO_ERROR: 
            msgText += "IO错误"; 
            break;
        case SWFUpload.UPLOAD_ERROR.SECURITY_ERROR: 
            msgText += "安全性错误n" + errorMsg; 
            break; 
        case SWFUpload.UPLOAD_ERROR.UPLOAD_LIMIT_EXCEEDED: 
            msgText += "每次最多上传 " + this.settings.uploadLimit + "个"; 
            break; 
        case SWFUpload.UPLOAD_ERROR.UPLOAD_FAILED: 
            msgText += errorMsg; 
            break; 
        case SWFUpload.UPLOAD_ERROR.SPECIFIED_FILE_ID_NOT_FOUND: 
            msgText += "找不到指定文件，请重新操作"; 
            break; 
        case SWFUpload.UPLOAD_ERROR.FILE_VALIDATION_FAILED: 
            msgText += "参数错误"; 
            break; 
        default: 
            msgText += "文件:" + file.name + "n错误码:" + errorCode + "n" + errorMsg + "n" + errorString; 
        }
        alert(msgText); 
    }
    return parameters; 
} 
var uploadify_onSelect = function(){ }; 
var uploadify_onUploadSuccess = function(file, data, response) { 
    alert(file.name + "nn" + response + "nn" + data); 
}; 
var uploadify_config = { 
    'uploader' : 'upload.php', 
    'swf' : '/js/uploadify/uploadify.swf', 
    'buttonImage' : '/images/uploadify-button.png',
    'cancelImg' : '/images/uploadify-cancel.png', 
    'wmode' : 'transparent', 
    'removeTimeout' : 0, 
    'width' : 80, 
    'height' : 30,
    'multi' : false, 
    'auto' : true,
    'buttonText' : '上传', 
    'hideButton' : 'true', 
    'fileTypeExts' : '*.png;*.jpg;*.jpeg', 
    'fileSizeLimit' : '1MB', 
    'fileTypeDesc' : 'Image Files', 
    'formData' : {"action": "upload", "sid" : ""}, 
    'overrideEvents' : [ 'onDialogClose', 'onUploadSuccess', 'onUploadError', 'onSelectError' ], 
    'onSelect' : uploadify_onSelect, 
    'onSelectError' : uploadify_onSelectError, 
    'onUploadError' : uploadify_onUploadError, 
    'onUploadSuccess' : uploadify_onUploadSuccess 
}; 
$("#id").uploadify(uploadify_config);

说明：由于FLASH的BUG导致在FF中上传时获取不到SESSION，可以使用formData来传值，如：

formData : { '<?php echo session_name();?>' : '<?php echo session_id();?>' }
