I have an input field on which the user types the city name, but what if the user types the city like this:
"New York "
" New York "
I used the trim function but that did not work, any suggestion?
const city = "New York ";
console.log(city.trim());How can I remove all the white spaces so I can save the city in the state as "New York"?
You can also use replace to replace all consecutive space characters with one space:
const str = "New York "
" New York "
const res = str.replace(/\s+/gm, " ").trim()
console.log(res)Alternatively, you can split the string by a space, filter out the empty items, then join back by a space:
const str = "New York "
" New York "
const res = str.split(" ").filter(e=>e).join(" ")
console.log(res)Combine the string.replace() method and the RegEx and replace it with a single string. Notice the starting and ending spaces will be kept and stripped down to a single space. Trim any surrounding spaces from the string using JavaScript’s string.trim() method
const city = " New York ";
console.log(city.replace(/\s+/g, ' ').trim());
