MimeTypeArray

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The MimeTypeArray interface returns an array of MimeType instances, each of which contains information about a supported browser plugins. This object is returned by the deprecated Navigator.mimeTypes property.

This interface was an attempt to create an unmodifiable list and only continues to be supported to not break code that's already using it. Modern APIs represent list structures using types based on JavaScript arrays, thus making many array methods available, and at the same time imposing additional semantics on their usage (such as making their items read-only).

Instance properties

MimeTypeArray.length Deprecated

The number of items in the array.

Instance methods

MimeTypeArray.item() Deprecated

Returns the MimeType object with the specified index.

MimeTypeArray.namedItem() Deprecated

Returns the MimeType object with the specified name.

Example

js
const mimeTypes = navigator.mimeTypes;
const pdf = mimeTypes.namedItem("application/pdf");

if (pdf) {
  console.log(pdf.description);
}
