Hello fantastic people!

I need help clicking a button in our support portal. It has a workflow behind push buttons that ask the user questions. I want to make a very simple 'Submit' button for them as its a little complicated currently. This will be added to a much friendlier instruction box on the bottom of my page.

Please can anyone advise how i would click 'SubmitOrder' in JavaScript? Below is the code from inspecting the element:

Code:
<li class="actionPanelItem" callback="" params="{ "function_name": "SubmitOrder", "function_type": "None", …lse, "is_multiselect": false, "custom_function_params": "" }">
I will be clicking this from an iFrame embedded in the page as i cant edit the core code.

Thanks for any guidance!

Dan
