A
BrowserSetting
object that can be used to enable or disable the ability of web pages to open popups in response to user actions.
The underlying value is a boolean.
By default, browsers allow web pages to open popups in response to a particular set of events: for example,
click
,
mouseup
,
submit
。若
allowPopupsForUserEvents
被设为
false
, no user events will be able to open popups. If it is set to
true
, the default set of events will be allowed to open popups.
For example, suppose a web page has code like this:
window.addEventListener("click", (e) => {
window.open("https://example.com","myPopup",'height=400,width=400');
});
By default, this will open a popup window. If your extension sets
allowPopupsForUserEvents
to
false
, then it will not open a popup, and the user will be informed that the popup was blocked.
BCD tables only load in the browser
Toggle the setting:
function toggleAllowPopup() {
function toggle(current) {
console.log(`Current value: ${current.value}`);
browser.browserSettings.allowPopupsForUserEvents.set({value: !current.value});
}
browser.browserSettings.allowPopupsForUserEvents.get({}).then(toggle);
}
browser.browserAction.onClicked.addListener(() => {
toggleAllowPopup();
});
