找不到变数：iOS 7上的Promise [英] Can't find variable: Promise on iOS 7

问题描述

iOS 7 Safari报告错误找不到变量：Promise ：

iOS 7 Safari is reporting the error Can't find variable: Promise:

new Promise(function(resolve, reject) {
.
.
.

白色其他浏览器没有这个问题，我发现这个类似的问题罗伯特给出了一个解决方案来添加新的Ember.RSVP.Promise 而不是新的Promise 。

White other browsers don't have this issue, I found this similar question where Robert gave a solution to add new Ember.RSVP.Promise instead of the new Promise.

我的问题是我没有使用jQuery，这使所有浏览器都返回错误， Ember 没有定义，我发现添加 Ember.min.js 解决了这个问题，但是增加了额外的$ code> 129.96 KB 到我的页面，这对我的项目来说不是很好。

My problem is that I'm not using jQuery and that makes all browsers return an error that Ember is not defined, and I found that adding Ember.min.js solves the issue, but that adds extra 129.96 KB to my page which is not good at all to my project.

我只是想解决iOS7的问题，我很感激，如果有人知道他如何告诉我们

I just want to fix the problem for iOS7, and I appreciate if somebody who knows how he tell us.

推荐答案

您需要包含一个polyfill for br不支持本机的承诺的输入。这是一个轻量级的，很容易使用：

You need to include a polyfill for browsers that don't support promises natively. Here is a light weight one that is easy to use:
