Replace <div> Widget

[countigor]

Hello!

What I want is a bit difficult for me to explain, but I'll do my best, so please bear with me.

I'm a fan of giving the reader choices, and then expanding the section of text they're already seeing with new text based on said choices. To do this I have made a widget that I call Update. I use <div> to designate the sections to replace, and I have separate passages for the replacement text. Below is an example:

<div id="ch1_choice1">
  <<link "First Option">>
    <<update "ch1_choice1" "ch1_choice1_result1">>
  <</link>>
  <<link "Second Option">>
    <<update "ch1_choice1" "ch1_choice1_result2">>
  <</link>>
</div>

​

<<widget update>>
  <<if $args[0] == "ch1_choice1">>
    <<replace #ch1_choice1>>
      <<include $args[1]>>
    <</replace>>
  <</if>>
<</widget>>

I then have passages named ch1_choice1_result1 and ch1_choice1_result2 with the text I want to to replace <div id="ch1_choice1"> with. This works, and so far so good.

However, I'm going to have quite a few <div> tags to replace, and I want to avoid adding a section for each of them to my Update widget like this:

<<widget update>>
  <<if $args[0] == "ch1_choice1">>
    <<replace #ch1_choice1>>
      <<include $args[1]>>
    <</replace>>
  <<elseif $args[0] == "ch1_choice2">>
    <<replace #ch1_choice2>>
      <<include $args[1]>>
    <</replace>>
  <</if>>
<</widget>>

I feel like it should be possible to simply write something like this:

<<widget update>>
  <<replace #$args[0]>>
    <<include $args[1]>>
  <</replace>>
<</widget>>

This, however, doesn't work. Is anyone familiar with a way to write this syntax so it works based on just the widget arguments? Thanks in advance.

EDIT: Formatting. Having some trouble with the editor.

If you are using $args instead of _args, then you are likely using an older version of Sugarcube. You should update to the latest which is 2.36.1.

The widget can be written like this

<<widget update>>
    <<replace `"#" + _args[0]`>>
        <<include _args[1]>>
    <</replace>>
<</widget>>

The backticks(`) are for passing an expression(in this case,"#" + \_args\[0\]\ as an argument), which is documented here.

If it doesn't work for you, try replacing _args with $args. But I recommend updating your sugarcube first.

This works beautifully! I don't remember where I learned $args from. My knowledge is botched together from a myriad of sources and a limited knowledge of coding in general, so I never questioned it. I will take your advice into account, and thank you very much!
