Omniture的SiteCatlayst跟踪：错误从调用使用jQuery在函数中s.tl（）时不绑定到单击事件

问题描述

我想，当用户使用Omniture的自定义链接跟踪提交表单跟踪。此功能利用内置的功能 s.tl（）。一个典型的设置是这样的：

I want to track when a user submits a form using Omniture's "Custom Link Tracking". This feature utilizes the built-in function s.tl(). A typical setup looks like this:

$('a#submit').click(function () {
    s.trackExternalLinks = false;
    s.linkTrackVars = 'events,prop1';
    s.linkTrackEvents = s.events = 'event1';
    s.prop1 = s.pageName;
    s.tl(this, 'o', 'Form Submitted');
});

这code正常工作时，例如链接（＆LT;一个ID =提交＆GT; ）被点击。再说了，相反，我们要调用一个函数来触发该链接跟踪：

This code works fine when the example link (<a id="submit">) is clicked. Say, instead, we want to call a function to trigger the link tracking:

// function to track custom link
var trackLink = function() {
    s.trackExternalLinks = false;
    s.linkTrackVars = 'events,prop1';
    s.linkTrackEvents = s.events = 'event1';
    s.prop1 = s.pageName;
    s.tl(this, 'o', 'Form Submitted');
};

// Form Submission code calls trackLink()
$.ajax({
    type: 'POST',
    url: submit.php,
    data: [data],
    success: trackLink()
});

调用 trackLink（）的结果未定义，presumably因为此在 s.tl（）不再指向一个DOM对象？更换这的东西，如 $（'A＃提交'）[0] （试图将对象传递给它而不是这个）也导致未定义。我究竟做错了什么？

Calling trackLink() results in undefined, presumably because the this in s.tl() no longer points to a DOM object? Replacing this with something like $('a#submit')[0] (trying to pass an object to it instead of this) also results in undefined. What am I doing wrong?

推荐答案

有关s.tl的第一个参数只能有两个值中的一个。

The first parameter for s.tl can only have one of two values.

如果该功能被称为的onclick处理程序的元件，则它需要的值 - 这 - ，而在这种情况下，解决了在元件的href属性的值。如果这是通过为第一参数，然后加载新页面之前的功能将创建500ms的延迟，这是为了保证有足够的时间用于跟踪呼叫的发送。

If the function is being called as the onclick handler for an element, then it takes the value - this -, which in this case resolves to the value of the href attribute of the element. If this is passed as the first parameter, then the function will create a 500ms delay before the new page is loaded, this is to ensure there is enough time for the tracking call to be sent.

如果该功能被称为在任何其他情况下，包括作为形式或AJAX的成功处理程序的一部分，那么第一个参数必须是文字 - 真的 - 。在这种情况下，该函数不添加延迟，但仍会发送跟踪呼叫

If the function is being called in any other context, including as part of a form or ajax success handler, then the first parameter has to be a literal - true -. In this case, the function doesn't add the delay, but will still send the tracking call.

在你的情况下，正确的签名是这样的：

In your case the correct signature is this:

s.tl(true, 'o', 'Form Submitted');
