Using data return from sharepoint assetimagepicker

I'm working with Sharepoint 2007. I use the built in AssetImagePicker.aspx and I need to retrieve the image url from that page and use it in my custom webpart. I want to run my javascript code to run when clicking the OK button of the AssetImagePicker.aspx but I can't find a way 开发者_如何学JAVAto do that. Does anyone know how to do this? Thanks

Not sure if I'm understanding the question properly, and I know nothing about Sharepoint (and AssetImagePicker.aspx) but it sounds like you want to add an event handler to the OK button: to run a function when the click event of the button is fired.

You can either code event handling yourself (see W3Schools or Quirksmode for examples of this) or (probably better) use a library like jQuery.
