indexOf with window.location not working

Why is this not working?

<html>
<head>

<script type="text/javascript">
      function test1(){
            if (window.location.indexOf('http')) {
                  alert('yes');
            } else {
                  alert('no');
            }
      }
</script>
<body>

<a href="javascript:test1();">test</a>

Use window.location.href.indexOf('http') instead.

Where the "http" is at the beginning of the string, indexOf returns 0. In the IF test, 0 is treated as false. Change it to this:

if(window.location.indexOf('http') > -1) {

Actually you want

<script type="text/javascript">
function test1(){
if (window.location.indexOf('http')==0) { // see if the location STARTS with http
alert('yes');
} else {
alert('no');
}
}
</script>
<body>

<a href="#" onClick="test1(); return false">test</a>

The solution I accepted is not working. This is _always_ alerting both the if.
The url does not start with the value, so I am not testing for -1 or == 0

<script type="text/javascript">
      function test1(){
            if (window.location.href.indexOf('foo.')) {
                  alert('Hi, this is FOO.');
            }
            if (window.location.href.indexOf('bar.')) {
                  alert('Hi, this is BAR.');
            }

      }
</script>
