Restrict Bad Words from Input and textarea

I am trying to validate input value and textarea text against Bad words.
Below code is working fine for single Badword and sentence which contains a badword.

badWords - contains the list of bad words
fieldValue contains input/Text area text

var badText = fieldValue.split(" ");
for (i = 0; i < badWords.length; i++)

if(badWords[i] != "")

if(badText.indexOf(badWords[i].trim()) > -1)
return true;



return false;


Now I am facing issue with below format. Please suggest me how to restrict the below bad word Badword: B a d w o r d

EDIT: The question is not how to filter but how to find the cases where the word is spelled with spaces in between.

textArr.some((x) => badWords.includes(x))

I would remove all spaces from the words and compare each using includes.

So, for each item you would use replace with the regexp / /g to remove all whitespace, then convert all letters to lowercase so the search is case insensitive using toLowerCase() on both strings (the input string and the bad word string).

/ /g

toLowerCase()

function getBadWords(str)
let badwords = ['spider', 'monkey', 'pig']
let words =
badwords.forEach(word =>
str.replace(/ /g, '').toLowerCase()
.includes(word.replace(/ /g, '').toLowerCase()) ? words.push(word) : null)
return words


const tests = [
'I am a spider',
'This looks like a p i g',
'Look at that Mon Key',
'That spider looks like a monkey',
'Silly words',
'Fancy S p i d e r'
]

tests.forEach(sentence =>
let foundWords = getBadWords(sentence)
console.log(foundWords)
console.log('Is bad: ' + (foundWords.length > 0))
)

s p i d e r

s p i d e r

You can store all the words you don't like in an array and then check if the value of the textarea includes any one of them.

let badwords = ["badword", "flip", "hobgoblin", "turtleneck"], ele = document.querySelector.bind(document);
btn = ele("button"), ta = ele("textarea");

btn.addEventListener("click", () =>
for(let badword of badwords)
if(ta.value.replace(/s/gm, "").includes(badword)) return alert("found " + badword + "!");

alert("all clean!");
);

<textarea></textarea><button>detect!</button>

If you split the fieldValue by spaces, you won't be easily able to search for bad words. The easiest solution would be to replace split with trim replace(/ /g,'') to replace all spaces, like:

split

trim

replace(/ /g,'')

var badText = fieldValue.replace(/ /g,'');

for (i = 0; i < badWords.length; i++)

if(badWords[i] != "")

if(badText.indexOf(badWords[i]) > -1)
return true;
