Autosubmit a Formidable-Form on pageload and onclick (wordpress) -- 2

I’m looking for a solution to auto-submit a search-form I have created with the formidable forms plugin (on wordpress) on pageload (1.) and on click (2.). The search-form is needed to filter the content of a formidable-form-view. 1.: Auto-submit the search-form on pageload 2.: Auto-submit on click (As in many search-forms in www it would be great if users have a way to filter the content of a formidable-form-view instantly by just choose a value like "last year", "Full HD", "best rated" etc. and then see the search-results on formidable-view instantly, without pressing the submit-button any single time they adjust the filter) You should download the (free) formidable forms plugin on your own website and find that solution, then you tell me how it works and I will implement it on my website by myself.
