I need to compare titles (which are made of many words) with a list of bad words. For one word, indexOf works fine. but when there are many swear words it doesn't.
Can anyone help with this?
var title = "This is my title";
var badwordlist = title.indexOf('fword and other bad words list');
//var badwordlist = title.indexOf('fword');
if ( badwordlist >= 0){
//do something
}
I feel the two answers posted so far are overdoing things
var title = "fword This is a f**king title.",
words = title.split(" "),
badwords = ["fword", "f**king"];
// one of these should do it
var isGood = words.filter(function(a) {
return badwords.indexOf(a) == -1;
});
var isBad = words.filter(function(a) {
return badwords.indexOf(a) != -1;
});
console.log(isBad, isGood);
// if isBad.length>0 then there were swear words in the title
return isBad.length>0You can use String.prototype.includes() to check if the string contains the bad word:
var title = "fword This is title.";
var badwords = ["fword", "f**k"];
var isbad = badwords.map(function(a) {
return title.includes(a);
});
console.log(isbad);
This is a simple solution, which involves an array, a cycle and a function which coordinates these
var badwords = ['fword', 'uglyword'];
var replacements = ['*word', 'ug***ord'];
function replaceBadwords(title) {
for (var badwordIndex in badwords) {
if (title.indexOf(badwords[badwordIndex]) >= 0) {
title = title.split(badwords[badwordIndex]).join(replacements[badwordIndex]);
}
}
}
However, the word 'assignment' contains an ugly word, which in fact is not ugly. I mean if you read only the first three characters, you will think this is an ugly word. To cope with these exceptions make sure you will not censor these as well.
See this SO question. This will do:
var arr = ['banana', 'monkey banana', 'apple', 'kiwi', 'orange'];
function checker(value) {
var prohibited = ['banana', 'apple'];
for (var i = 0; i < prohibited.length; i++) {
if (value.indexOf(prohibited[i]) > -1) {
return false;
}
}
return true;
}
arr = arr.filter(checker);
console.log(arr);Obtain arr by splitting your title on space, eg title.split(" ").
Once you do any filtering you can create a filtered title with title = arr.join(" ").
title.split(" ")
indexOf
