示例 -

var url_regex = /((www\.|(http|https|ftp|news|file)+\:\/\/)[&#95;.a-z0-9-]+\.[a-z0-9\/&#95;:@=.+?,##%&~-]*[^.|\'|\# |!|\(|?|,| |>|<|;|\)])/;

$('#test').click(function(){
    console.log(url_regex.test($('#test_field').val()));
    console.log(email_regex.test($('#test_field').val()));

    if(!(url_regex.test($('#test_field').val()) || email_regex.test($('#test_field').val()))){
        alert("You must enter a valid email or you must enter a valid url, which starts with http://. The www prefix is optional.")
    }
