Matching exact string with JavaScript

Question

How can I test if a RegEx matches a string exactly?

var r = /a/;
r.test(\"a\"); // returns true
r.test(\"ba\"); // returns true
testExact(r, \"ba\")

var data =   {"values": [
    {"name":0,"value":0.12791263050161572},
    {"name":1,"value":0.13158780927382124}
]};

//JSON to string conversion
var a = JSON.stringify(data);
// replace all name with "x"- global matching
var t = a.replace(/name/g,"x"); 
// replace exactly the value rather than all values
var d = t.replace(/"value"/g, '"y"');
// String to JSON conversion
var data = JSON.parse(d);
