Redirect Code Example

In this example, all links with class rdp_jb_must_sign_in are assigned an event listener that sets a cookie, with the cookie value derived from the link’s href attribute. The cookie name should always be rdp_ll_login_redirect.

When the pop-up log-in window executes its close script, the function rdp_ll_login_onClose is called, and it reloads the page to show that the visitor is logged in. In the document.ready() function, the cookie is read, then deleted, and the parent window is redirected to the appropriate URL.

Example Code of Custom Sign-In JavaScript File

var $j=jQuery.noConflict(); // Use jQuery via $j(...) $j(document).ready(rdp_sign_in_onLoad); function rdp_sign_in_onLoad(){ var redirectPath = Cookies.get('rdp_ll_login_redirect'); var loggedIn = $j('body').hasClass('logged-in'); if(loggedIn && redirectPath && redirectPath != 'undefined'){ Cookies.remove('rdp_ll_login_redirect', { path: '/' }); window.location.href = redirectPath; } $j('#rdp-jb-main').on( "click", '.title.rdp_jb_must_sign_in' , function(event){ event.preventDefault(); var redirectURL = $j(this).attr('href'); var date = new Date(); date.setTime(date.getTime()+(30*1000)); Cookies.set('rdp_ll_login_redirect', redirectURL, {expires: date, path: '/' }) }); }//rdp_sign_in_onLoad function rdp_ll_login_onClose(redirect_url){ window.location.reload(); }//rdp_ll_login_onClose
