未捕获到的SyntaxError：意外令牌；

Question

I am trying to inject Facebook pixel code using jQuery .

I couldn't find a direct way of doing it and hence following the below approach. However, I am getting an syntax error.

var t = "!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, ; 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');fbq('init', '274827424829492');fbq('track', 'SomePage');";

$('<script>').attr('type', 'text/javascript').text(t).appendTo('head');

I am getting an error on var t = '.......';

The mistake was at the concatenated string. Below is the correct string.

var t = "!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');fbq('init', '3535353535355');fbq('track', 'SomePage');";
