search.get() 编辑

Gets an array of all installed search engines.

Each search engine returned is identified with a name, which you can pass into search.search() to use that particular engine to make a search.

This is an asynchronous function that returns a Promise.

Syntax

var gettingEngines = browser.search.get()

Parameters

None.

Return value

A Promise that will be fulfilled with an array of search engine objects. Each search engine object may contain the following properties:

name

string. The search engine's name.

isDefault

boolean. true if the search engine is the default. Only one search engine can be the default at any given time.

aliasOptional

string. If a search engine has an alias, the user can search with a particular search engine by entering the alias in address bar before the search term. For example, if the Wikipedia engine has an alias "wk", the user can search Wikipedia for pandas by entering "wk pandas" in the address bar. The alias is sometimes also called a "keyword".
