Zooms the specified tab.
This is an asynchronous function that returns a
Promise
.
var zooming = browser.tabs.setZoom(
tabId
,
// optional integer
zoomFactor
// number
)
tabId
可选
integer
. The ID of the tab to zoom. Defaults to the active tab of the current window.
zoomFactor
编号
. The new zoom factor. Use a value of 0 here to set the tab to its current default zoom factor. Otherwise, this must be a number between 0.3 and 5, specifying a zoom factor.
A
Promise
that will be fulfilled with no arguments after the zoom factor has been changed. If the tab could not be found or some other error occurs, the promise will be rejected with an error message.
Set the zoom factor for the current tab to 2:
function onError(error) {
console.log(`Error: ${error}`);
}
var setting = browser.tabs.setZoom(2);
setting.then(null, onError);
Set the zoom factor for the tab whose ID is 16 tab to 0.5:
function onError(error) {
console.log(`Error: ${error}`);
}
var setting = browser.tabs.setZoom(16, 0.5);
setting.then(null, onError);
BCD tables only load in the browser
