Text input box without submit button?

wraithrose

Using Twine 2, Sugarcube 2.

I have a text input, where the player can type something and stuff will happen depending on what they typed.

My problem: The way I have it set up, they have to press a "submit" button to get results.

Is there a way to make it so they just have to press enter?

Thanks!

SugarCube 2's <<textbox>> macro will forward you to the specified passage when enter/return is pressed, by default. So, if using <<textbox>> is an option and you're processing the player's entered text in the next passage, then just pass it the appropriate passage argument.

If <<textbox>> isn't an option, then you're going to need to specify some details. Specifically, what kind of text input are you using and what does the "submit" button do?

This is what I have, as an example:
<<textbox "$action" "" autofocus>><<button "submit">>


<<if $action neq "">>
<<if $action.split(" ").contains("kittens")>>
<<replace "#ActionText">><<print "There are kittens">><</replace>>

<<elseif $action eq "laugh">><<replace "#ActionText">><<print "AHAHAHAHAHAHA">><</replace>>

<<elseif $action eq "cry">><<replace "#ActionText">><<print "WAAAAAHHHHHHHHH">><</replace>>

<<else>><<replace "#ActionText">><<print "Nothing happens.">><</replace>>

<</if>>
<</if>>

<<if $action eq "">><<replace "#ActionText">><<print "Type in the action you'd like to take">><</replace>><</if>>

<</button>>


My issue is that in order to process whatever the player types in the text box, they have to click the submit button -- can I make it so they just have to press enter/return, instead of having to click a button?

You're really asking how to bind the submit button to the enter key.

The input macros are, generally, designed to be passed on to another passage for validation. In particular, if you specify a forwarding passage to <<textbox>>, it will forward upon enter/return.

To validate within the same passage, via either <<click>> or <<button>>, you will instead need to hook enter/return keypresses within the <<textbox>> so that they trigger a click on your <<button>>.

Also, you are doing several unnecessary things within your <<button>> code.

Here's what I'd suggest for your <<textbox>> and <<button>>:

<span class="textenter">\
<<textbox "$action" "" autofocus>> \
<<button "Submit">>

<<if $action eq "">>
	<<replace "#ActionText">>Type in the action you'd like to take.<</replace>>
<<elseif $action.split(" ").contains("kittens")>>
	<<replace "#ActionText">>There are kittens.<</replace>>
<<elseif $action eq "laugh">>
	<<replace "#ActionText">>AHAHAHAHAHAHA<</replace>>
<<elseif $action eq "cry">>
	<<replace "#ActionText">>WAAAAAHHHHHHHHH<</replace>>
<<else>>
	<<replace "#ActionText">>Nothing happens.<</replace>>
<</if>>

<</button>>\
</span>

And the following to enable the functionality you want: (goes in Story JavaScript)

postdisplay["text-enter-setup"] = function () {
	$(".textenter .macro-textbox").on("keydown", function (evt) {
		if (evt.which === 13) {
			evt.preventDefault();
			$(".textenter")
				.find(".macro-textbox")
					.trigger("change")
				.end()
				.find(".macro-button")
					.trigger("click");
		}
	});
};
