基本代码适用于除IE之外的所有浏览器

Question

I am able to use this code to display a PDF document except on Internet Explorer.

It says:

ReferenceError: 'fetch' is undefined

I can't find much about this. What can I do to make it work?

   fetch("data:application/pdf;base64," + vm.documentData.base64Document).then(function(response) {
        response.blob().then(function(blob) {
            document.querySelector("iframe").src = URL.createObjectURL(blob) + "#view=fit";
        });
    });

You need to add the 'isomorphic-fetch' module to your 'package.json' and then import this.

npm install --save isomorphic-fetch es6-promise

Then in your code

import "isomorphic-fetch"

See https://www.npmjs.com/package/isomorphic-fetch
