check url without http and ".com"

Question

I would like to check if the given url is valid.

It should accept:

www.gmail.com

and should reject:

www.gmail

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

It works but if the given input is www.gmail it does accepts it.

Any Ideas?

try this .It is working for me

<script type="text/javascript">
    function validate() {
        var url = document.getElementById("url").value;
        var pattern = new RegExp("^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}([0-9A-Za-z]+\.)");
        if (pattern.test(url)) {
            alert("Url is valid");
            return true;
        } 
            alert("Url is not valid!");
            return false;

    }
</script>

In jQuery

you can use url validation

<input type="text" class="url"/>

@Dreyfus15 did you checked this – PSR Mar 20 '13 at 04:27
tried it. but "www.gmail.com" works even "www.gmail" is accepted. It must not be accepted since "www.gmail" is not a valid url. – n0minal Mar 20 '13 at 04:36
@Dreyfus15 i specified 2 patterns which one you used – PSR Mar 20 '13 at 04:39
I tried both. see http://jsfiddle.net/aabanaag/VktaX/ link though it is not updated. – n0minal Mar 20 '13 at 04:42

You could use Jquery Validate plugin for that.

$("#myform").validate({
  rules: {
    field: {
      required: true,
      url: true
    }
  }
});

You can find about it here

solved my problem:

found this while googling over the internet.

 /^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}[0-9A-Za-z\.\-]*\.[0-9A-Za-z\.\-]*$/


var pattern1 = /^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}[0-9A-Za-z\.\-]*\.[0-9A-Za-z\.\-]*$/;

var result = "www.gmail";

if (pattern1.test(result)) {
    console.log("test");
}else{
    console.log("fail");
}

It works best.

check url without http and ".com"
