重定向到同一网站，但链接不同（javascript）

Question

I want that people in "example.com/index.htm" get redirected to "example.com". but the code is being tricky. It always takes me to a loop.

<script type="text/javascript">
function check()
{
 if (window.top!="example.com") 
 {
  window.location="http://example.com";
 }else {} 
}</script>

Answer 1

<script type="text/javascript">
function check()
{
if (window.top.location.href!="http://mysite.com") 
 {
window.top.location.href="http://mysite.com";
}else {} 
}</script>

You need to use the location object and it needs to actually match.

Answer 2

Give this a go (untested):

$(function() {

    var reg = /index.htm/g,
        top = window.location.href,
        loc = '';

    if(reg.test(top)) {

        top = top.replace('http://','');
        top = top.split('/');

        for(i=0;i<top.length-1;i++) {
            loc = loc + top[i];
        }

        window.location.href = 'http://' + loc;
    }

});
