从外部JS文件使用谷歌Analytics（分析）异步code [英] Using Google Analytics asynchronous code from external JS file
问题描述
我想加入谷歌Analytics（分析）的异步版本跟踪code到网站。
我想保持的JavaScript在一个单独的文件，并从那里调用它。
下面就是我目前在我的.js文件了：
函数addLoadEvent（FUNC）{
VAR oldonload =的window.onload;
如果（typeof运算的window.onload！='功能'）{
在window.onload = FUNC;
}其他{
在window.onload =函数（）{
oldonload（）;
FUNC（）;
}
}
}功能loadtracking（）{
VAR _gaq = _gaq || [];
_gaq.push（['_ setAccount'，'UA-XXXXXXX-X']）;
_gaq.push（['_ trackPageview的']）; （函数（）{
VAR GA =使用document.createElement（'脚本'）; ga.type =文/ JavaScript的'; ga.async = TRUE;
ga.src =（的https：== document.location.protocol的https：// ssl的'：'HTTP：// WWW'？）+'。谷歌-analytics.com / ga.js的';
变种S = document.getElementsByTagName（'脚本'）[0]; s.parentNode.insertBefore（GA，S）;
}）（）;
}addLoadEvent（loadtracking）;
和这里就是我在已经得到了＆LT; HEAD＆GT; 我的母版页标记：
＆LT;脚本类型=文/ JavaScript的SRC =JS /谷歌的analytics.js＆GT;＆LT; / SCRIPT＆GT;
不过，显然是一个问题，因为几天后，我没有通过！让统计
任何想法我需要改变吗？
谢谢，
尼尔
编辑：确定...以下一些反馈后，我要加我的.js文件的新的的当前内容。我会保持更新，因此，如果/当这得到解决，希望能帮助其他人试图做类似的事情。
VAR _gaq = _gaq || [];功能loadtracking（）{
window._gaq.push（['_ setAccount'，'UA-XXXXXXX-X']）;
window._gaq.push（['_ trackPageview的']）; （函数（）{
VAR GA =使用document.createElement（'脚本'）; ga.type =文/ JavaScript的'; ga.async = TRUE;
ga.src =（的https：== document.location.protocol的https：// ssl的'：'HTTP：// WWW'？）+'。谷歌-analytics.com / ga.js的';
变种S = document.getElementsByTagName（'脚本'）[0]; s.parentNode.insertBefore（GA，S）;
}）（）;
}loadtracking（）;
您VAR _gaq是一个函数内。这意味着它的局部范围该函数内部，并不会整体存在。 GA依赖于全局变量_gaq。如果你想保持这样的功能在里面，引用它作为window._gaq。
I'm trying to add the asynchronous version of the Google Analytics tracking code to a website.
I'd like to keep the JavaScript in a separate file, and call it from there.
Here's what I've currently got in my .js file:
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
oldonload();
func();
}
}
}
function loadtracking() {
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXXX-X']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
}
addLoadEvent(loadtracking);
And here's what I've got in the <head> tag of my Master page:
<script type="text/javascript" src="js/google-analytics.js" ></script>
However, there's obviously a problem as after a few days, I'm not getting stats through!
Any ideas what I need to change?
Thanks, Neil
EDIT: Ok... After some feedback below, I'm going to add the new current contents of my .js file. I'll keep it updated so that if/when this gets solved, it will hopefully help other people trying to do similar things.
var _gaq = _gaq || [];
function loadtracking() {
window._gaq.push(['_setAccount', 'UA-XXXXXXX-X']);
window._gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
}
loadtracking();
Your "var _gaq" is inside a function. That means it's locally scoped inside that function and won't exist globally. GA depends on the global variable _gaq. If you want to keep it inside a function like that, reference it as window._gaq.
