I have a SinglePageApplication built with AngularJs. I want too add Facebook Custom Audience tracking pixel globally and update it manually every time user changes page (url). <
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window,document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
// initialize facebook pixel code
fbq('init', {SET-YOUR-ID}); // <-- replace {SET-YOUR-ID} with your facebook pixel convesion id
// disabled automatic push state for single web application
fbq.disablePushState = true;
// then call manually track PageView event
fbq('track', 'PageView');
Into Single Page Application(SPA) you must disabled automatic listen on push State, pop State and windows history as Facebook pixel library by default hook into windows.history and push/pop state.
