Variables in replace

[stuckwithcode]

Hello, with the code below how could I amend it to replace a variable for a variable

 

text = text.replace(/peter/gm,"mark");

 

eg

 

var name = "peter";

var repname = "mark"

 

How do i put variables in the code instead of strings

 

 

[trq]

text = text.replace(name,repname);

You won't be able to put a variable into that style of writing a regular expression and just providing it to replace will only replace the first instance of the word. Instead, create a RegExp object as below.

 

var text     = "hello peter, you are awesome.";
var name     = "peter";
var replace  = "mark";

var regex    = new RegExp(name, "g");
text = text.replace(regex, replace);

 

Note that the variable's contents will be evaluated as a regular expression, special characters and all!

How can i put

name = array[1];

 

where name is an array of names, i cant seem to get this to work, can you help?

 

var text    = "hello peter, you are awesome.";

var name    = "peter";

var replace  = "mark";

 

var regex    = new RegExp(name, "g");

text = text.replace(regex, replace);

Just access it with name[1]
