思ったより大変でした。それが役に立てば幸い。

index.html
<load class="trigger">loading triggers ga event</load>
<button class="button1">fire ga event with address</button>
<button class="button1" id="clickme">multiple events</button>
ここで場所のバインドが行われ、jquery が場所を適切に使用できるようになります。
event: {
value: ["trackPageview",$(location).attr('href')],
validation: "isString",
type: "string"
}
これを使用するというあなたのアプローチは正しかったのですが、それを ga に入れるには、以前に場所を取得する必要がありました。とにかくこのフォーマットのようです
$("#button").gaa(options).click(function () {
$(this).toggleClass("changeIt");
});
正しい方向へと導いてくれます。
これは楽しい頭の体操でした。これにより、後で必要な場所で location.href にアクセスできるようになります。考え方としては、DOM の準備ができてから _gaq を実行する前にバインドを形成するというものです。
