Your regex works well by you can make it more elegant like following:
你的正则表达式运作良好,你可以使它更优雅如下:
/^(?:[A-Za-z\d]{5}-){3}[A-Za-z\d]{5}$/

What about this.
那这个呢。
var data = "5char-5char-5char-5char";
if(data.match(/^(?:[a-z\d]{5}-){3}[a-z\d]{5}$/,"i"))
{
console.log("Ok");
}
Don't forget to add ^ and $.
别忘了添加^和$。
