Uncaught SyntaxError: Unexpected token = in Google Chrome

问题描述

我有一个接受可选参数的 javascript 函数.这在 Firefox 中运行良好，但在 Google Chrome 中显示:-

I have a javascript function which accept an optional parameter. This works fine in Firefox, but in Google Chrome it shows:-

Uncaught SyntaxError: Unexpected token =

我的代码，

function errorNotification(text = "Something went wrong!") {
  $.pnotify({
      title: 'Error',
      text: text,
      type: 'error'
  });
}

我见过很多类似的问题，但我无法意识到我的问题.

I have seen lot of similar questions but I can't realize my problem.

推荐答案

您使用的是 默认参数 特性，现在只有 Firefox 支持.

You are using a default parameter feature which is supported only by Firefox now.

function errorNotification(text) {
    text = text || "Something went wrong!";
    $.pnotify({
        title: 'Error',
        text: text,
        type: 'error'
    });
}
