Hello, this is my first time in stackoverflow, and I'm having a hard time, I need to know how I can detect parts of a string, for example:
String: "Definir a altura de %s para %d"
I want information % s and % d
Example:
"Definir a altura de objeto para 500"
Output:
Saída: "objeto", 500
Is there any way to get this? NOTE: The output does not have to be mandatory in some data type, it can be output in 2 variables, 1 array or anything.
NOTE: Javascript language.
Thank you.
If the phrase is always the same as you said, you can do this:
let phrase = "Definir a altura de cadeira para 500";
//quebra a frase no primeiro "de"
let part1 = phrase.split(' de ');
//quebra a frase no primeiro "para"
let part2 = part1[1].split(' para ')
console.log(part2[0])
console.log(part2[1])If you want something more dynamic, you can create a function where the first parameter will be the phrase itself and the last two will be the delimiters to perform the sentence break.
Example:
function getPhrase(phrase, param1, param2) {
let phrases = phrase;
//quebra a frase no primeiro "de"
let part1 = phrases.split(" "+param1+" ");
//quebra a frase no primeiro "para"
let part2 = part1[1].split(" "+param2+" ")
//console.log(part2[0])
//console.log(part2[1])
let result = [ {'1': part2[0].trim(), '2': part2[1].trim() }];
return result;
}
$(document).ready(function(){
let obj = getPhrase('Definir a altura de cadeira para 500', 'de', 'para');
console.log(obj)
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>Remembering that I made the examples based on your information and that the code can easily be adapted.
I'll leave a more secure solution using regular expressions, because if "object" contains spaces, using split can generate errors.
var frase = "Definir a altura de objeto para 500";
var objeto = frase.replace(/^Definir a altura de (.*) para (.*)$/, '$1');
var numero = frase.replace(/^Definir a altura de (.*) para (.*)$/, '$2');
console.log(objeto, numero);You can use the split function by sending an empty space as a separator, returning an array.
Ex:
const frase = 'Definir a altura de objeto para 500';
frase.split(' ');
// [ 'Definir', 'a', 'altura', 'de', 'objeto', 'para', '500' ]
Because an empty space was used as a separator, an array with all words in the string is returned. You can get them by index.
frase[4];
// objeto
I hope I have helped!
