    Hi Neha and welcome to Lithosphere,

     

    Usually it's preferrable to handle IP information in Freemarker code. Can you share some more details on what you want to achieve based on the IP address?

     

    If you really really need it in JavaScript it should be possible to have your custom component populate a JavaScript variable with the freemarker one like this:

    <script type="text/javascript">
   var RemoteIP = ${http.request.remoteAddr};
</script>

    ...or if you need this info on every page instead of creating a custom component you can add this code to your Lithium skin's header wrapper.

    Just to back up what Claudius has already said, you need to bear in mind that any JavaScript variables can be easily changed by the user within their browser. Therefore it's important that you don't rely on the IP address being correct for anything important (e.g. authentication, security etc.).

    Are you just trying to hide the link, or do you need to prevent those users from logging in?

     

    Technically, it may be possible to hide all of the registration links (but not prevent registration altogether) using jQuery. However, there are so many different places in the community that link to the registration page that I suspect it would be difficult to hide them all.

     

    Lithium may have an option to disable registration for users with a certain IP address, which may be a more sensible option.

    Basically if you just need to hide the UI element you just need to identify the CSS class or ID and then add the following code to your custom component:

    <#if ${http.request.remoteAddr} == "127.0.0.1">
<style>
    a.lia-component-users-action-login {display : none !important;}
    </style> 
    </#if>

     Alternatively using jQuery:

     

    <#if ${http.request.remoteAddr} == "127.0.0.1">
<@liaAddScript>
;(function($) {
$(document).ready(function() {
    $('.lia-component-users-action-login').hide();
 });
})(LITHIUM.jQuery);
</@liaAddScript>
</#if>

     Whatever seems easier to you ;)
