非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Navigator.msSaveBlob() method saves the File or Blob to disk. This method behaves in the same way as Navigator.msSaveOrOpenBlob() except that this disables the file open option.

句法

navigator.msSaveBlob(blob, defaultName);

参数

blob
defaultName

返回值

True is returned as long as the download notification bar is displayed, or false if a failure occured.

注意事项

When a site calls this method, the behavior is the same as when Windows Internet Explorer downloads a file with the following in the header, where X-Download-Options removes the file open button from the browser file download dialog:

Content-Length: <blob.size>
Content-Type: <blob.type>
Content-Disposition: attachment;filename=<defaultName>
X-Download-Options: noopen

规范

Not part of any specifications.
