SCRIPT5009:“获取"未定义

问题描述

有一些麻烦！对于我的请求，我正在使用 Fetch API！

提交表单在 IE 中不起作用，因为SCRIPT5009: 'fetch' is undefined"！

示例如下:

fetch("url",{方法:POST"，正文:JSON.stringify(数据)，标题:{'接受': '应用程序/json',内容类型":应用程序/json"}}).then(函数(响应){return response.json().then(function (data)

同时在 Chrome 和 FF 中运行良好！我已经在尝试在 Google 上寻找一些解决方案，但是没有用！

我尝试在 npm 中安装isomorphic-fetch"和es6-promise"，并尝试将其导入到我的 .js 文件中，但同样失败，控制台显示:Uncaught SyntaxError: Unexpected令牌导入"！顺便说一句， required() 函数也不能正常工作！所以我现在完全不知道该做什么，如何使用这些 polyfill 之类的东西！

如果有人有想法，请提前致谢！BR！

可以使用https://github.com/github/fetch 代替.

CDN:https://cdnjs.com/libraries/fetch

<script src="https://cdnjs.cloudflare.com/ajax/libs/fetch/2.0.3/fetch.js"></script>

如果你需要 Promise polyfill，你可以使用 http://bluebirdjs.com/docs/install.html

<script src="//cdn.jsdelivr.net/bluebird/3.5.0/bluebird.min.js"></script>

在fetch之前加载Bluebird:

<script src="//cdn.jsdelivr.net/bluebird/3.5.0/bluebird.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/fetch/2.0.3/fetch.js"></script>

have some troubles! For my requests i'm using Fetch API!

Submit form don't work in IE, because of "SCRIPT5009: 'fetch' is undefined"!

Example how it's looks like:

fetch("url",
        {
             method: "POST",
             body: JSON.stringify(data),
             headers: {
                 'Accept': 'application/json',
                 'Content-Type': 'application/json'
             }
         }).then(function (response) {
             return response.json().then(function (data)

Same time in Chrome and FF it's works fine! I'm already trying to find some solutions surfing Google, but it was unhelpful!

I was tried to installing "isomorphic-fetch" and "es6-promise" in npm, and tried to import it in my .js file, but it was unsuccessful as well, console shows me this: "Uncaught SyntaxError: Unexpected token import"! Btw, required() function don't work as well! So I'm totally don't now what to do, how to use these polyfill thing and all of that!

If some ones have an idea, thanks in advance! BR!

You can use https://github.com/github/fetch instead.

CDN: https://cdnjs.com/libraries/fetch

<script src="https://cdnjs.cloudflare.com/ajax/libs/fetch/2.0.3/fetch.js"></script>

If you need Promise polyfill you can use http://bluebirdjs.com/docs/install.html

<script src="//cdn.jsdelivr.net/bluebird/3.5.0/bluebird.min.js"></script>

Load Bluebird before fetch:

<script src="//cdn.jsdelivr.net/bluebird/3.5.0/bluebird.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/fetch/2.0.3/fetch.js"></script>
