JavaScript .replace only replaces first Match [duplicate]

Question

You need a /g on there, like this:

var textTitle = "this is a test";
var result = textTitle.replace(/ /g, '%20');

console.log(result);

You can play with it here, the default .replace() behavior is to replace only the first match, the /g modifier (global) tells it to replace all occurrences.

textTitle.replace(/ /g, '%20');

Try using a regex instead of a string for the first argument.

"this is a test".replace(/ /g,'%20') // #=> "this%20is%20a%20test"

For that you neet to use the g flag of regex.... Like this :

var new_string=old_string.replace( / (regex) /g,  replacement_text);

That sh

The same, if you need "generic" regex from string :

const textTitle = "this is a test";
const regEx = new RegExp(' ', "g");
const result = textTitle.replace(regEx , '%20');
console.log(result); // "this%20is%20a%20test" will be a result
    

From w3schools

The replace() method searches for a match between a substring (or regular expression) and a string, and replaces the matched substring with a new substring

Would be better to use a regex here then:

textTitle.replace(/ /g, '%20');
