Google自定义JavaScript解析错误

Question

我正在尝试创建一个自定义JavaScript GTM变量。

但它一直告诉我我有一个解析错误..。

Error at line 4, character 53: Parse error. ')' expected

但我看不出有什么问题。有什么不对吗？

​

function() {
  var clickclasses = "{{Click Classes}}";
  if (clickclasses.includes("download-color-wheel") {
    return "Downloaded Color Wheel";
  }
  if (clickclasses.includes("lp-10%-coupon") {
    return "Claimed 10pct Coupon on Landing Page";
  }
  if (clickclasses.includes("exit-popup-10%-coupon") {
    return "Claimed 10pct Coupon on Exit Popup";
  }
  if (clickclasses.includes("video-testimonial-submitted") {
    return "Video Testimonial Submitted";
  }
  return "Clicked";
}

Answer 1

省略if语句的括号。

更新代码：

function() {
  var clickclasses = "{{Click Classes}}";
  if (clickclasses.includes("download-color-wheel")) {
    return "Downloaded Color Wheel";
  }
  if (clickclasses.includes("lp-10%-coupon")) {
    return "Claimed 10pct Coupon on Landing Page";
  }
  if (clickclasses.includes("exit-popup-10%-coupon")) {
    return "Claimed 10pct Coupon on Exit Popup";
  }
  if (clickclasses.includes("video-testimonial-submitted")) {
    return "Video Testimonial Submitted";
  }
  return "Clicked";
}
