If the word in the sentence is also in the array, take the first 3 letters of this word and put a period at the end.
var arr = ['select', 'delete', 'Truncate', 'insert', 'update']
function checkValue(value, arr) {
var newText;
for (var i = 0; i < arr.length; i++) {
var name = arr[i];
if (value.toLowerCase().includes(name.toLowerCase())) {
newText = value.toLowerCase().replace(name, name.substring(0, 3));
break;
}
}
return newText;
}
console.log(checkValue('Hello Hello Delete33 Hello', arr));Its giving me : hello hello del33 hello.
But I want : Hello Hello Del. Hello.
You can create a regex matching your arr items after a word boundary and consuming any word chars after them, and replace with the first three chars appending a dot right after:
var arr = ['select', 'delete', 'Truncate', 'insert', 'update']
var re = new RegExp("\\b(?:" + arr.join('|') + ")\\w*", 'ig')
function checkValue(value, re) {
return value.replace(re, (x) => x.substr(0,3) + ".");
}
console.log(checkValue('Hello Hello Delete33 Hello', re));
// => Hello Hello Del. HelloSee the regex demo. Details:
\b - a word boundary(?:select|delete|Truncate|insert|update) - a non-capturing group matching one of the words\w* - zero or more word chars (letters, digits, _).var arr = ['select', 'delete', 'truncate', 'insert', 'update']
function checkValue(value, arr) {
return value.split(" ").map(x => arr.find(y => x.toLowerCase().includes(y)) ? x.substring(0, 3) + "." : x).join(" ");
}
console.log(checkValue('Hello Hello Delete33 Hello', arr));The key thing is that you're getting the substring but retaining the numbers, and not adding a full-stop.
Here's an alternative method using map, some, and join.
const arr = ['select', 'delete', 'Truncate', 'insert', 'update'];
function checkValue(value, arr) {
// `split` the string into words, and `map`
// over them
return value.split(' ').map(word => {
// If one of the lowercase words in the array
// is included included in the lowercase word...
const found = arr.some(el => {
return word
.toLowerCase()
.includes(el.toLowerCase());
});
// ...return the updated word
if (found) return `${word.slice(0, 3)}.`;
// Otherwise just return the word
return word;
// And `join` the array back to a string
}).join(' ');
}
const str = 'Hello Hello Delete33 Hello Truncate';
const out = checkValue(str, arr);
console.log(out);Additional documentation
