JavaScript - passing variable to regular expression

Question

I want to do some sort of searching with this:

if (v.name.search(new RegExp(/peter/i)) != -1) {
    console.log('found peter's record');
}

But how can I put a variable into that regular expression? I have tried with v.name.search(new RegExp('/'+var+'/i')), but it didn't work.

Thank you.

What are you expecting the variable to contain? A proper regex like [a-z] or peter? — Henrik Andersson

That should be:

if (v.name.search(new RegExp(myVar, "i")) != -1) {
    console.log('found '+ myVar +' record');
}

See MDN for further info.
