Alphanumeric strings correspond as follows:

^[a-zA-Z0-9]+$

It matches any string that contains only the listed characters and has a length of at least one char.

With special characters, it will work the same way.

But what do you think is a special char?

! @# $% ^ & *() + = - []\';../{} | ": < > ? - , :

^[@!#\$\^%&*()+=\-\[\]\\\';,\.\/\{\}\|\":<>\? ]+$

, . , , \.

, .

function validate()
{
        var val = <my string>;

        if (val == '')
            alert('String is empty!');

        else if (!val.match(/[_\W]/))
            alert('String contains only A-Z a-z 0-9 characters!');

        else if (!val.match(/^\w[@!#\$\^%&*()+=\-\[\]\\\';,\.\/\{\}\|\":<>\?]/))
            alert('String contains your predefined characters only!');
}

if (val.match(/[^_\W]/) && val.match(/[@!#\$\^%&*()+=\-\[\]\\\';,\.\/\{\}\|\":<>\? ]/))
    alert('String contains both alpha-numeric and your pre-defined special characters!');

:

if (val.match(/(?=.*[@!#\$\^%&*()+=\-\[\]\\\';,\.\/\{\}\|\":<>\? ]+?).*[^_\W]+?.*/)
    alert('String contains both alpha-numeric and your pre-defined special characters!');
