Question

I want to add “*.” at opening and “;” at ending on each array element. Below is the sample code.

var ext = getExt(filename);
var s = '<%=AllowedExtensions %>';
var match = s.split(', ');

In the above code in ‘match’ I use to get [“jpg”, “png”, “txt”] like this. So here on each array element I want to prefix with “.” and at end of each want to add “;” and also it should give me a string such as “.jpg;.png;.txt;” .

Answer 1

Try this:

var matchString = '.' + match.join(';.') + ';'
