正则表达式替换引号之间的值

Question

Im trying to replace 2 variable values in a file. I read the file contents in nodejs into a string. And I need to search for these variables and replace their values.

original string

var useStub = false;var serviceUrl = 'http://servicetest.test.com';

I want to run some sort of command like

var result = someFile.replace(regex, 'http://servicestage.stage.com');
var result = someFile.replace(regex, 'true');

After this command I want the output like

var useStub = true;var serviceUrl = 'http://servicestage.stage.com';    

I tried a couple of regex patterns but it didnt get the output I need. I have very little exp with regexes. Can someone help me with this?

Got it working finally with help from @FloatingCoder.

var text = "var useStub=false;var serviceUrl='http://servicetest.test.com';var hello='sdfdsfs';";
text = text.replace(/var serviceUrl='.*?';/, "var serviceUrl='http://newurl.test.com';");
text = text.replace(/var useStub=.*?;/, "var useStub=true;");
console.info(text);

Here is the fiddle for others

Try this...

var text = "var useStub = false;var serviceUrl = 'http://servicetest.test.com';";

text = text.replace(/var serviceUrl = '.*?';/, "var serviceUrl = 'http://newurl.test.com';");
text = text.replace(/var useStub = .*?;/, "var useStub = true;");

document.getElementById("output").innerHTML = text;

This might need more tweaking, depending on what else is in the file, but from what you've given, this will work.

There's a JSFiddle to play with here .
