Try this
tell application "Firefox"
activate
tell application "System Events"
keystroke tab
keystroke (key code 125)
keystroke (key code 125)
keystroke (key code 125)
end tell
end tell
You might not need to activate Firefox if it's the current active app. Them you just need :
tell application "System Events"
keystroke tab
keystroke (key code 125)
keystroke (key code 125)
keystroke (key code 125)
end tell
For a minute there I thought you were asking the same question again as last time.
But realise now you want to know how to use Inspect Element to construct your own code.
In the example you give: document.forms[WHATGOESHERE?].click()
The WHATGOESHERE would be the form name.
i.e document.forms['theFormName'].click()
Your website in their wisdom has named the form 'form'
<form method="post" action="/cgi-bin/RNAfold.cgi" enctype="multipart/form-data" name="form">
<input type="hidden" name="PAGE" value="2">
i.e document.forms['form'].click()
But this would not click the input button
You can use the submit() function dot syntax'd on the end :
document.forms['form'].submit()
Safari Applescript : do JavaScript "document.forms['form'].submit()"
Also
In the code I provided you in your last question. I used:
tell document 1
do JavaScript "document.getElementsByClassName('proceed')[0].click()"
end tell
This uses the class Name proceed of the forms input element seen here: class="proceed"
<input value="" name="proceed" type="submit" class="proceed" onmouseover="this.style.cursor="pointer"" style="cursor: pointer;">
The getElementsByClassName('proceed')[0]
does exactly what it says.
It gets the Elements By ClassName 'proceed'.
The [0] means it will give you the first element in it's results from the Array that would be returned. The array is counted from 0-9. So the first item would be item 0.
A good place to get working examples and information about Javascript is at www.w3schools.com On the front page the have links to their HTML and Javascript examples and Tutorials. The elements of the HTML Dom and Javascript functions are listed for easy access.

If you had an alert dialog appearing with an OK button, then this AppleScript code would close it.
You'll likely need to customise this to fit your exact situation. If the alert dialog appears with a title you can all specify that as below.
Another option would be to identify the alert by using "front window" as in the following example (assuming the alert is the front window).
Hope this helps.
