dynamically setting properties in uploadify

Question

is it possible to add a new property to a previously declared object? Here is some code to clarify (with the uploadify jquery plugin):

$(\'#featuredimageuplo         


        

Answer 1

I believe what you are looking for is this:

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

You can also get the current value by leaving the second parameter off:

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

Answer 2

Yes it is possible to add properties (dynamic or otherwise) to an existing Javascript object). You can just use the [] operator to add a dynamic property to an object. For example:

var key = 'foo';
var obj = {param: 'value'};
obj[key] = 'bar';
alert(obj.foo); // bar
