以下是使用 Google Analytics 通用事件跟踪方法而不是 GA 标准事件跟踪的更新方法。
整个 UTM 字符串可以从 queryString 中提取（如果有）或从 Google cookie (__utmz) 中提取，然后使用以下代码传递给 Google Analytics。
ga('send', 'event', 'queryString', 'getQueryString', googleString );
然后，在执行您想要创建的任何触发器时（我使用名为“widgetTracker”的函数），您可以执行 GA 事件跟踪器。
这是整个代码：

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-xxxxxxx-xx', 'xx.xxx');
ga('send', 'pageview');
var googleString;
var stringArray = [];
var queryStringObject = makeQueryStringObject();
var QUOT = "'";
var EQ = '=';
var AMP = '&';
for ( var v in queryStringObject ) {
var str = v + EQ + queryStringObject[v] ;
stringArray.push(str);
googleString = stringArray.join(AMP);
}
function makeQueryStringObject() {
var obj = [];
var pageURL = window.location.href;
var URLArray = pageURL.split('?');
if( URLArray[1] ) {
var argsArray = URLArray[1].split('&');
var l = argsArray.length;
for( i=0; i<l; i++ ) {
var individualArg = argsArray[i].split('=');
if(individualArg[1] && individualArg[1].indexOf('#') > -1) {
var dropHashArray = individualArg[1].split('#');
individualArg[1] = dropHashArray[0];
}
obj[ individualArg[0] ] = individualArg[1];
console.log("value of queryStringObject: " + individualArg[0] + " :: " + obj[ individualArg[0] ]);
}
