JavaScript .replace only replaces first Match [duplicate]

This question already has answers here: 开发者_StackOverflow社区 How do I replace all occurrences of a string in JavaScript? (78 answers) Closed 3 years ago.

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

But the replace functions stops at the first instance of the " " and I get the

Result : "this%20is a test"

Any ideas on where Im going wrong im sure its a simple fix.

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');

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');

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

"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

Try using replaceWith() or replaceAll()
