我正在尝试通过 Google 通用分析设置事件跟踪。我找到了一个看起来完全符合我需要的脚本示例——即跟踪页面中的各种锚点点击并相应地对它们进行分类。然而，我对 javascript 的理解仍然很初级，我需要帮助来理解为什么这个脚本不起作用。基本上点击事件似乎根本没有被触发。我检查了 - 脚本加载正常，并且可以在加载时显示一个警报框。在加载了 analytics.js 和 Jquery 之后，该脚本被放置在页面头部的最后部分。

希望这是我所缺少的显而易见的东西，非常感谢。罗伯特

From what you have given there are few things that can go wrong there

  1. There is no base tag in the page. You need to have a <base href="" /> in the page
  2. The script is added inside head . Then the body element is still not loaded so you need to add the script inside dom ready handler/register the delegated handler to document object instead of body

Assuming jQuery is loaded correctly and it is added before this script try

<base href="yourbaseurl" />

then

if (typeof jQuery != 'undefined') {
    jQuery(function(){
        var filetypes = /\.(zip|exe|dmg|pdf|doc.*|xls.*|ppt.*|mp3|txt|rar|wma|mov|avi|wmv|flv|wav)$/i;
        var baseHref = '';
        if (jQuery('base').attr('href') != undefined) baseHref = jQuery('base').attr('href');
        var hrefRedirect = '';

        jQuery('body').on('click', 'a', function(event) {

            var el = jQuery(this);
            var track = true;
            var href = (typeof(el.attr('href')) != 'undefined' ) ? el.attr('href') : '';
            var isThisDomain = href.match(document.domain.split('.').reverse()[1] + '.' + document.domain.split('.').reverse()[0]);
            if (!href.match(/^javascript:/i)) {
                var elEv = []; elEv.value=0, elEv.non_i=false;
                if (href.match(/^mailto\:/i)) {
                    elEv.category = 'email';
                    elEv.action = 'click';
                    elEv.label = href.replace(/^mailto\:/i, '');
                    elEv.loc = href;
                }
                else if (href.match(filetypes)) {
                    var extension = (/[.]/.exec(href)) ? /[^.]+$/.exec(href) : undefined;
