webFrame
The web-frame
module allows you to customize the rendering of the current
web page.
An example of zooming current page to 200%.
var webFrame = require('electron').webFrame;
webFrame.setZoomFactor(2);
Methods
The web-frame
module has the following methods:
webFrame.setZoomFactor(factor)
factor
Number - Zoom factor.
Changes the zoom factor to the specified factor. Zoom factor is zoom percent divided by 100, so 300% = 3.0.
webFrame.getZoomFactor()
Returns the current zoom factor.
webFrame.setZoomLevel(level)
level
Number - Zoom level
Changes the zoom level to the specified level. The original size is 0 and each increment above or below represents zooming 20% larger or smaller to default limits of 300% and 50% of original size, respectively.
webFrame.getZoomLevel()
Returns the current zoom level.
webFrame.setZoomLevelLimits(minimumLevel, maximumLevel)
minimumLevel
NumbermaximumLevel
Number
Sets the maximum and minimum zoom level.
webFrame.setSpellCheckProvider(language, autoCorrectWord, provider)
language
StringautoCorrectWord
Booleanprovider
Object
Sets a provider for spell checking in input fields and text areas.
The provider
must be an object that has a spellCheck
method that returns
whether the word passed is correctly spelled.
An example of using node-spellchecker as provider:
webFrame.setSpellCheckProvider("en-US", true, {
spellCheck: function(text) {
return !(require('spellchecker').isMisspelled(text));
}
});
webFrame.registerUrlSchemeAsSecure(scheme)
scheme
String
Registers the scheme
as secure scheme.
Secure schemes do not trigger mixed content warnings. For example, https
and
data
are secure schemes because they cannot be corrupted by active network
attackers.
webFrame.registerUrlSchemeAsBypassingCsp(scheme)
scheme
String
Resources will be loaded from this scheme
regardless of the current page's
Content Security Policy.
webFrame.registerUrlSchemeAsPrivileged(scheme)
scheme
String
Registers the scheme
as secure, bypasses content security policy for resources and
allows registering ServiceWorker.
