Javascript regex to match a six digit number

Question

I am trying to include a regex that I used differently in the past in some validation check via JavaScript.

Below is my script:

    var regOrderNo = new RegExp("\d{6}");
    var order_no = $("input[name='txtordernumber']").val();
    alert(regOrderNo.test(order_no));

Why not return with true if the text box txtordernumberwas a six-digit number or more?

Answer 1

Insert an extra "\" in your regular expression.

Answer 2

When used inside a string, you need to avoid \.

new RegExp("\\d{6}");

or

/\d{6}/

Answer 3

. "\ d", .

...

var regOrderNo = new RegExp("\\d{6}");
