标签管理器错误:未捕获的类型错误:w[l]。推不是函数

I'm seeing this error "Uncaught TypeError: w[l].push is not a function" in my Google Tag Manager javascript. What's going on?

我看到这个错误"未捕获类型错误:w[l]。在我的谷歌标记管理器javascript中，push不是函数。这是怎么呢

I'm using the normal GTM script, and I've got a simple dataLayer defined:

我使用的是普通的GTM脚本，我定义了一个简单的dataLayer:

<script>
  dataLayer = {
    "foo": "bar"
  }
</script>

2 个解决方案

dataLayer must be a list of objects, not an object.

dataLayer必须是对象的列表，而不是对象。

Instead of:

而不是:

<script>
  dataLayer = {
    "foo": "bar"
  }
</script>

Use:

使用:

<script>
  dataLayer = [{
    "foo": "bar"
  }]
</script>

This error also occurs if you're using the dataLayer.push method with an = sign.

如果使用dataLayer的话，也会出现这个错误。用=号推方法。

Wrong: dataLayer.push = ({ Correct: dataLayer.push({

错误的:dataLayer。push =({正确:dataLayer.push)
