TypeError:对象在IE 11中不支持此操作 [英] TypeError: Object doesn't support this action in IE 11

问题描述

这在谷歌浏览器中工作正常，但是在我的代码下面提到的行中，Internet Explorer中出现错误.谁能建议我要对它进行哪些更改才能在IE中工作.

This is working fine in google chrome but getting error in internet explorer at below mentioned line in my code. Can anyone suggest what change do i need to make to it to work in IE.

var file = new File([JSON.stringify($localStorage)], "somefile.txt", {type: "text/plain;charset=utf-8"});

推荐答案

链接到原始答案

为了解释链接，IE 11不支持new File()构造函数，因此您必须使用blob代替.这是一个基本示例:

To paraphrase the link, IE 11 does NOT support new File() constructor, so you'll have to use a blob instead. Here is a basic example:

var myArr = ["Hello", "World", "123", "Howdy"];
var b = new Blob([JSON.stringify(myArr)], {type: "text/plain;charset=utf-8"});
window.navigator.msSaveBlob(b, "OutputFile.txt");

现在您应该会收到一个下载提示.

And now you should receive a download prompt.
