how to use switchdiv( ) method in views?

I have four tables called: video audio image audio each table ia having differnet parameters.

While iam uploading new stream i can choose video/audio/image/audio and i can update corresponding table params; Here I am using switchdiv() method to do swith between ldifferent table parameters like below:

                      <select name="content" onchange="switchDiv (value);">             <option value="video_parameters">Video</option>             <option value="image_parameters">Image</option>             <option value="speech_parameters">Speech</option>             <option value="audio_parameters">Audio</option>                       </select>

the above code will create a dropdown box with video,audio,image and speech params.

Here what i want to do is instead of using "value" param in the above code i want to use the paarams selected by using below method: collection_select(:stream, :connenttype_id, @connenttypes, :id, :name) %>

with this code i am getting dropdown box of video,audio,image and speech params. Now if i select "video" parameter from dropdown box ,how to link this parameter to the switchDiv(value) method in the place of "value".

Can any one give the suggestions or help to do the same.

thanks srikanth
