I want to make use of a form\_remote\_tag to submit a form  
asynchronously. Easy done. However, we also want to add an  
observe\_form tag to check for some value changes while the form is  
being entered.

The observe\_form tag needs a dom id to work on but I can’t see how to  
enter an html option for the dom id of the form on the  
form\_remote\_tag.

Any ideas?

Here is the form tag so far…

\<%=form\_remote\_tag :loading=\>“showProgress()”,  
:complete=\>“showForm()”,:url=\>{:action=\>:new,  
:controller=\>“sample\_controller”}, :update=\>“sampleForm”%\>

</div>

Use

\<%=form\_remote\_tag :loading=\>“showProgress()”,  
:complete=\>“showForm()”,:url=\>{:action=\>:new,  
:controller=\>“sample\_controller”}, :update=\>“sampleForm”,  
:html =\> {:id =\> ‘your-super-cool-id’}%\>

Last line is where it’s different

Hope this helps!

Excellent - that did the trick. Thanks for your help - the whole area  
of html options is not well-documented on the api page, the fact that  
it says html\_options and not html is misleading for starters.

Thanks again
