如何加载某些javascript只在特定页面上延迟，而不是所有页面

Question

I have a page(not post) in wordpress for ex: http://www.xxxxxx.com/how-we-do-proceed/

I am using lot of javascript in the site but above the page is not related to any cart or plugin. This page is very important for us in the term of SEO, so I want to load few of javascript as defer. for ex: a.js, b.js, c.js etc.

All javascript added via WordPress handler.

How can I do it? any example of code welcome.

I think you can do it with plain javascript like this:

var tag = document.createElement("script");
tag.src = "http://xxxxxx.com/js/a.js";
document.getElementsByTagName("head")[0].appendChild(tag);

Or, if you use jQuery, you can do it like this:

$.getScript("http://xxxxxx.com/js/a.js");

Hope it helps!
