why the method replace replace only the fisrt match?

[Nati323]

hello , i did the next code:

 

var s = "hello hello hello hello";document.write(s.replace("hello", "bye"));

and the result :

bye hellp hello hello

 

why is that? i want that the all "hello" will be replaced, do i have to use rexexp (/hello/g) ?

That's the default behavior. You can either specify some additional flags to make the replace global, or its more popular to use a regular expression with the global flag.https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

The MSDN documentation suggests that IE does not support the third parameter, you'll need to use a regular expression.https://msdn.microsoft.com/en-us/library/ie/t0kbytzc(v=vs.94).aspx

Since that documentation is on MDN, it probably works in Firefox.
