javascript - 在 uploadify 中动态设置属性

Question

是否可以向先前声明的对象添加新属性？这里有一些代码需要澄清(使用 uploadify jquery 插件):

$('#featuredimageupload').uploadify({
        'uploader' : base_url + 'media/js/uploadify.swf',
        'script': base_url + 'post/uploadflash',
        'multi' : true,
        'queueID' : 'queue',
        'cancelImg' : base_url + '/media/images/cancel.png',
        'fileDesc' : 'Allowed Types: (*.jpg,*.png,*.gif)',
        'fileExt' : '*.jpg;*.JPG;*.gif;*.GIF;*.png;*.PNG',
        'queueSizeLimit' : 9,
        'sizeLimit': 1000000,
        'method' : 'GET',
        'buttonText' : 'Browse',
        'onComplete' : function(event, queue, obj, response, data){
            if(response =='false'){
                alert('Maximum number of images reached!');
                $('#uploader').uploadifyClearQueue();
                return false;
            }
        },
        'onError' : function(event,queue,file,error){
            alert('An error occured. No files were uploaded');
            $('#uploader').uploadifyClearQueue();
        }
    });

然后做类似的事情

$('#form').submit(function(){
   $('#featuredimageupload').uploadify({scripData : data})
})

我看到这是用 jqgrid 完成的

我相信你要找的是这个:

$("#form").submit(function(){
    var $upload = $("#featuredimageupload");
    $upload.uploadifySettings('scriptData', { key : value });
    $upload.uploadifyUpload(); // Triggers the upload to start.
});

您还可以通过关闭第二个参数来获取当前值:

var currentSetting = $upload.uploadifySettings('scriptData');
