Prepend backslashes for every dot

I'd like to prepend backslasher for every dot which is present in javascript. For instance: 

this.is.a.test

will give 

this\\.is\\.a\\.test

I tried this :

a = "this.is.a.test";
b = a.replace(".","\\.");

but b returns this\.is.a.test instead of this\\.is\\.a\\.test

Backslashes are used to escape strings, so how can I fix it?

Try this

a = "this.is.a.test";
b = a.replace(/\./g,"\\.");
//returns "this\.is\.a\.test"

for two backslashes do this 

a = "this.is.a.test";
b = a.replace(/\./g,"\\\\.");
//returns "this\\.is\\.a\\.test"
