網址驗證不起作用

我正在使用JavaScript網址驗證正則表達式。但它並不適用於所有工作辦案。希望下面的網址，就必須努力提供.com，。在等頁面沒有自動跳轉網址驗證不起作用

http://mysites.com 
    http://www.mysite.com 
    https://mysite.com 
    https://www.mysite.com 
    ftp://mysite.com 
    ftp://www.mysite.com 
    www.mysite.com 
    mysite.com 
    usa.mysite.com

我使用正則表達式，

var regex = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

它不適用於www.mysite.com和mysite.com等。

任何人都請幫助我。

你的反應是在這裏： http://stackoverflow.com/questions/1303872/trying-to-validate -url-using-javascript 請參閱：http：//stackoverflow.com/questions/3653884/php-regex-for-url-validation-filter-var-is-too-permisive [1]：http： // STAC koverflow.com/questions/1303872/trying-to-validate-url-using-javascript –

試試這個正則表達式：

var regex = /^(ht|f)tps?:\/\/[a-z0-9-\.]+\.[a-z]{2,4}\/?([^\s<>\#%"\,\{\}\\|\\\^\[\]`]+)?$/;

對不起，它不能正常工作。它不適用於「mysite.com」 –

<?php 
$url = "http://www.example.com"; 

if(!filter_var($url, FILTER_VALIDATE_URL)) 
{ 
    echo "URL is not valid"; 
} 
else 
{ 
    echo "URL is valid"; 
} 
?>
