Validating keywords in Text Entry/Data entry fields
Hi!
I am working on a simulation where the user is required to add a comment that must include some keywords. Is there a way to validate the comment against those keywords and if all the keywords ...
Hi Linah
You can test whether a string contains a given substring in JavaScript by using the includes() method. So if you have a variable 'textString' and you want to know whether the text 'cat' was included then you might use something like:
if textString.includes("cat") {
......}
The attached example (which needs a LOT of work - but gives you the idea) contains the JavaScript:
const key1 = "cat";
const key2 = "dog";
const key3 = "cow";
var found = ["","",""];
var player = GetPlayer();
var textString = player.GetVar("TextEntry");
if (textString.includes(key1)) {
found[0] = ("you mentioned " + key1 + "\n");
}
if (textString.includes(key2)) {
found[1] = ("you mentioned " + key2 + "\n");
}
if (textString.includes(key3)) {
found[2] = ("you mentioned " + key3 + "\n");
}
player.SetVar("response",(found[0]+found[1]+found[2]));
where TextEntry is the user input string you are testing and response is a text variable displayed in a text box on the screen
