URL target on a button. What is the syntax??

Question

I can't for the life of me fine any references to the syntax for the URL target attribute of a button. What is it?
I need to execute a javascript function prior to leaving the page via a button. Do I place its call in the URL target? I actually want to redirect to a page in the current application but there is no place to create 'additional link attributes' like in a column link.
any help appreciated.

Paul,
I may have a work around for you. Here are the steps I took to call a function and then branch to another page.
</br>
<ol>
<li>Create a 'Display as Text' item, do not enter a label value and select 'No Label' for the template option.</li>
</br>
<li>In the Pre Element Text area insert an opening anchor tag with the following text href="javascript:function()" replace 'function' with the actual name of the function you would like to call and enter any parameters.</li>
</br>
<li>In post element text close your anchor tag.</li>
</br>
NOTE for steps 2 and 3 you can also inclue an img tag to make the display item appear to be a button. Otherwise you can enter any text in the default value and that is your link.
<li>In the very last line of your function add the folowing text: doSubmit('NewPage');</li>
<li>Create a page branch and set the page attribute to the desired page. ex. 160</li>
<li>Set its condition to"Request = Expression 1"and enter the text "NewPage" for Expression 1</li>
</ol>
This will call your function and then the submit at the end of the function will trigger the branch to a new page.
Let me know if it helps or if you could find a better way.
