javascript return context key from variable

Antanas — Wed, 25 May 2022 15:28:35 GMT

Hi!

I have modified a simple Javascript automation, however i can't seem to put an input value as a context key. In the below sample i declare var Key = args.parent; and in the return statement i try to use this variable as context entry.

In reality, I literally get the context set to "Key", regardless on what I specify in the input. It is like the input variable is disregarded. What am i missing?

Thanks,

Antanas

Hi @Antanas, I'm guessing you're trying to modify the ToTable automation to save the data to a context key. I would suggest using the extent-context like this

!ToTable data=${File} columns="name,size" title="This is a table" extend-context=data=

If you still need to get the automation working, could you send me the yml file?

Hi @jfernandes1, for some reason extend-context does not work in this case. I specifically try extend-context=NewKey=Key Including the yml code, much appreciated for any ideas.

Hi @Antanas, I don't this you're using it right. Refer to the below screenshot. You do not need to specify a key after the "data=".

I still recommend the above method, but in case you want, I've corrected the code too.

I found a couple of issues with the script.

1. You cannot use 'parent' as a variable since it's a reserved word. Refer - https://www.w3schools.com/js/js_reserved.asp

2. I had to change the output of your script a little. Still not sure why yours did not work.

Hi @jfernandes1 - your updated script works perfectly fine - thanks! BTW, you still suggested to use extend-context which works after I removed the Key variable. However (I guess) it extends the normal output (seen as piped variables), and not the EntryContext, which should be an HTML table code.

Hi @Antanas, Just use the `!ConvertTableToHTML table=${newList} title="HTML Table"` command. You do not need to use the extend-context option since the code pass data to context under the HTMLTable key.
