All replacement methods for javascript replacement Functions

Next let's take a look at the article about replacing all the examples of javascript replacement functions. I hope this article will be helpful to you.

<Script language = "javascript">
Var r = "1n2n3n ";
// Replace the letter n with the component number
Alert (r. replace ("n ",";"));

Result: 1; 2n3n only replaces the first one.
</Script>

<Script language = "javascript">
Var r = "1n2n3n ";
// Replace the letter n with the component number
Alert (r. replace (/n/g ,";"));

Result: 1; 2; 3; the first parameter of replace can be a regular expression and/g indicates full-text matching.
</Script>

<Script language = "javascript">
Var strM = "javascript is a good script language ";
// Here I want to replace letter a with Letter
Alert (strM. replace ("a", ""));
</Script>

Only the first "a" letter can be replaced

<Script language = "javascript">
Var strM = "javascript is a good script language ";
// Replace all letters a with letters
Alert (strM. replace (/a/g, ""));
</Script>

Can replace all "a" Letters
