Re: [Stripes-users] how to submit a stripes form via Javascript

[Reuven G. <ga...@gm...>]

Hi Pankaj,

It is unclear from your email whether you are trying to use AJAX or do a
regular form submit. Either way, you need to specify the event handler by
passing in a request parameter since you are not doing button clicks. You
can pass-in a request parameter to specify the event handler (i.e. the
method name in the action bean) to call in one of the following 2 ways:

1) You can explicitly specify the event handler:

// The event handler method name is reloadTable
_eventName=reloadTable

2) Add request parameter name to request parameter [this is not explicit,
Stripes figures out that the parameter name matches an event handling
method]
reloadTable=

Now, there are a few ways of passing in the request parameter that you
want.  You can add a hidden form field with the event name
<input type="hidden" name="_eventName" value="" />

If this form is *only* going to be used to reload the table then you can
just hard-code the hidden form field's value to the reloadTable event
name.  However, if you are going to be using the form for other things then
you can update the value before each submit.

If you are using AJAX then, with YUI, you can serialize the form and add
extra parameters (_eventName)  or just build the query string and/or post
parameters and include the _eventName.

Let me know if you have any more questions.
