问题描述
我不太了解Google跟踪代码管理器中点击类"和点击元素"之间的区别.我不了解这些事件的预期用途，也不了解它们在包含"和"CSS选择器"方面的各自行为.
I don't really understand the differences between "Click classes" and "Click Element" in Google Tag Manager. I don't understand the expected use of these event and I don't understand their respective behavior regarding "contains" and "CSS selector".
假设我有class="buttons primary small".
工作原理:
Click Element -> Matches CSS selector -> .buttons.small
Click Classes -> contains -> small
什么不起作用
Click Element -> contains -> .buttons.small
Click Classes -> Matches CSS selector -> small
如果点击类"是对象上的类的数组"，那么在进行此类操作时GTM的幕后"到底发生了什么?
if Click Classes is "an array of the classes on an object", What's really happen "under the hood" of GTM when doing this kind of manipulation ?
这并不是我有一个真正的问题，只是试图正确理解.
It's not that I have a real issues, just trying to understand properly.
推荐答案
Click类返回作为操作目标的HTML元素的class属性值.它始终是一个字符串，在您的示例中将返回"buttons primary small"(尽管不一定按此顺序).
Click Classes returns the value of the class attribute of the HTML element that was the target of the action. It is always a string, and in your example would return "buttons primary small" though not necessarily in that order.
Click元素返回作为操作目标的HTML元素.
Click Element returns the HTML element that was the target of the action.
包含"是GTM中用于字符串的匹配类型.这就是为什么它适用于Click类(返回字符串)而不是Click元素的原因.
"contains" is a match type in GTM that you use against strings. That's why it works with Click Classes (which returns a string) and not Click Element.
匹配CSS选择器"用于检查是否有任何给定的元素与给定的CSS选择器匹配.因此，必须对HTML元素执行匹配CSS选择器".这就是为什么它可以与Click元素一起使用，而不与Click类一起使用的原因.
"Matches CSS Selector" is a check whether any given element matches a given CSS selector. "Matches CSS Selector" must thus be done against an HTML element. That's why it works with Click Element and not Click Classes.
我认为，点击类是多余的，因为相对于点击类，最好还是对点击元素进行CSS选择器检查，而不是对点击类进行字符串匹配.这样更健壮，并且您也不必担心类名称在类属性值中按特定顺序排列.
In my opinion, Click Classes is redundant, since you're always better off doing a CSS selector check against Click Element rather than a string match against Click Classes. It's more robust that way, and you also don't need to worry about the class names being in a certain order in the class attribute value.
换句话说，更好:
点击元素匹配CSS选择器 .buttons.primary.small
Click Element matches CSS selector .buttons.primary.small
更差:
点击类包含主要小按钮
