Executing Javascript inside a Ubot 3 or 4

[Chainsaw 9]

I've got some bots built with Zennoposter and want to port them over to Ubot.

 

In Zennoposter I made extensive use of Javascript to handle any complex data manipulation.

 

As far as I'm aware, Ubot can also execute Javascript but I can't figure out how to get the data out after executing the javascript.

 

I'm sure its very simple... Can someone point me in the right direction.

 

Cheers!

not sure how to get the data out after executing?

 

 

can you elaborate a bit more?

 

You could always add a define node, choose function, and drop the run JavaScript node in there.

 

then use a set node, to set a variable, and use the custom function you just created, in the content of the variable, as a means to execute the custom defined function, when the variable set node is ran.

Thanks LoWrIdErTJ, that is pretty much what I'm trying to do.

 

Unfortunately I'm still doing something wrong.

 

Here is a really simple example that should set #a to 10 but it leaves it undefined.

 

set(#a, 1, "Global")
define $js {
   run javascript("10;")
}
set(#a, $js(), "Global")
ui stat monitor("a=", #a)

There doesn't seem to be any way to return values from a javascript, whether or not its inside a function.

Sure you can. here is an example of something i am using in v4 now..

 

    set(#start date, $eval("var d = new Date(\"{#dte}\");
d.setDate(d.getDate());
var curr_date = d.getDate();
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();

curr_month + \"/\" + curr_date + \"/\" + curr_year;"), "Global")

Nice.

 

I couldn't find any documentation on this but with that example, you've made it much clearer.

 

Thanks

 

Is there any preset function to escape input to make it ready for JavaScript?

[LoWrIdErTJ - BotGuru 904]

using eval to execute the javascript.

 

if you copy that entire code, and paste it in ubot 4, you will see it setup in node view.

What I'd also like to do is escape line feed characters from a block of text, prior to processing the text with javascript.

 

Is there some built in function to take line feeds and turn them into javascript friendly \r\n ?

[Chainsaw 9]

Think I've found the answer to escaping line feeds when preparing blocks of text for processing with javascript.

 

set(#a, $replace regular expression(#a, $new line, "\r\n"), "Global")

Only essential command missing is "append to file".

 

If it is possible to pass parameters to a .bat file then might work...
