Deleting a named div

2017-10-28 Thread jgill 
I can do this in BBEdit and I can do it easily with Applescript, because it 
can search backwards for (?s).*? - but how 
can I search backwards with JavaScript? I want to be able to delete the 
last instance of this div on a web page.

Also, can I run JavaScript from within BBEdit on the front window instead 
of AppleScript?

TIA

Isn't it possible to use JS as an alternative to AS (system wide)? I 
mean I can select AS or JS in the script editor.

Re: Deleting a named div

First, "class='day_report'" isn't a named div. Second, if you are 
validating to HTML5, you would use ID instead of NAME. Third, using either 
ID or NAME, there should be only one of them on the page.

Per Jan Erik's post, you don't say if you are trying to do this locally on 
files on your hard drive or remotely on files on the server. If you are 
trying to delete on the server after the page is built (!), not being a 
JavaScript guru I would either use jQuery to set the contents of the div to 
nothing, or add a scrap of CSS to kill the display of that div.

But, it's a class not an ID, there are 30 of them on the page and I want to 
search and replace the last instance with ''.

I have worked out how to count the similar div classes on the page, go back 
to the top and count down  and then do a search and replace, but 
this seems clumsy.

OK. Your "subject" stated that you were trying to delete a named ID, so I 
took you at your word.

Do you truly need to *delete* it, or do you just want to make it
unavailable to the screen/screen reader?

If the latter, you could use the :last-child pseudo class in CSS, and set
it to display : none.
