如何动态更改Plupload url

I have setup Plupload to send to a PHP script checking for a parameter "gal" like:

我有安装Plupload发送到PHP脚本检查参数“gal”，如:

$("#uploader").plupload({
  url : 'upload.php?gal='+$('#gallery').val()
});

This retrieves the value from a drop down, but it grabs the value of the drop down when initialized. I need to change this every time the drop down is changed. I tried:

这将从下拉中检索值，但在初始化时获取下拉值。每次下拉菜单改变时，我都需要改变这个。我试着:

$("#gallery").change(function() {
  $('#uploader').data("uiPlupload").options.url = 'upload.php?gal='+$(this).val();
});

This is changes the url for this value, however I guess this isn't the correct parameter as even though I can see in Firebug that this changes, it still uses the initialized value.

这改变了这个值的url，但是我猜这不是正确的参数，即使我可以在Firebug中看到这个改变，它仍然使用了initialized值。

I have also tried:

我也试过:

$("#uploader").bind('BeforeUpload', function(up, file) {
  up.settings.url = 'upload.php?gal='+$("#gallery").val();
});

This doesn't get triggered at all.

它根本不会被触发。

Can someone shed some light on how I would change this?

有人能解释一下我该如何改变吗?

Thanks.

谢谢。

Figured it out. You have to get the uploader instance and then set in the settings like:

算出来。你必须获取上传者实例，然后设置如下:

$("#gallery").change(function() {
    var up = $('#uploader').plupload('getUploader');
    up.settings.url = 'upload.php?gal='+$(this).val()
});
