You can also click elements with JavaScript:
tell application "Google Chrome" to tell active tab of window 1
execute javascript "document.getElementById('chrome-web-store-title').click()"
--execute javascript "document.querySelectorAll('.tile-grid .most-visited')[3].click()"
end tell
Focusing an existing tab by URL:
tell application "Google Chrome"
repeat with w in windows
set i to 1
repeat with t in tabs of w
if URL of t starts with "https://mail.google" then
set active tab index of w to i
set index of w to 1
return
end if
set i to i + 1
end repeat
end repeat
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.

An easy way to do this is to use the Automator "Watch Me Do" feature, then convert it to Applescript.
