Gets the text color for the browser action's badge.
From Firefox 63, unless the badge text color is explicitly set using
browserAction.setBadgeTextColor()
, then the badge text color will be automatically set to black or white so as to maximize contrast with the specified badge background color. For example, if you set the badge background color to white, the default badge text color will be set to black, and vice versa.
Other browsers always use a white text color.
This is an asynchronous function that returns a
Promise
.
browser.browserAction.getBadgeTextColor(
details
// object
)
details
对象
.
tabId
可选
integer
. Specifies the tab to get the badge text color from.
windowId
可选
integer
. Specifies the window from which to get the badge text color.
windowId
and
tabId
are both supplied, the function fails.
windowId
and
tabId
are both omitted, the global badge text color is returned.
A
Promise
that will be fulfilled with the retrieved color as a
browserAction.ColorArray
.
BCD tables only load in the browser
Log the badge's text color:
function onGot(color) {
console.log(color);
}
function onFailure(error) {
console.log(error);
}
browser.browserAction.getBadgeTextColor({}).then(onGot, onFailure);
