Javascript Split, Replace acting strange

I am trying to format a string into word+word+word

For example

"ultra music festival" into "ultra+music+festival"

I have tried using following codes

query.split(" ").join("+");

or

query.replace(" ", "+");

however, both ways will give me

"ultra+music festival"

what is causing this issue, and how can i fix it ?

The first version (split/join) should work as-is (if the second space is really a space).

To replace more than one space using replace(), you'll need the g flag:

 query.replace(/ /g, "+");

To replace multiple spaces (or tabs, or other whitespace) in a row, you'd use:

 query.replace(/\s+/g, "+");

so that "one two three" would still turn into "one+two+three".

the global attribute is important.

Example!

var str = "Mr Blue has a blue house and a blue car"; 
var res = str.replace(/blue/g, "red");

in this case:

query.replace(/ /g, "+");
