# webFrame
|
|
|
|
> Customize the rendering of the current web page.
|
|
|
|
An example of zooming current page to 200%.
|
|
|
|
```javascript
|
|
const {webFrame} = require('electron');
|
|
|
|
webFrame.setZoomFactor(2);
|
|
```
|
|
|
|
## Methods
|
|
|
|
The `webFrame` 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` Number
|
|
* `maximumLevel` Number
|
|
|
|
Sets the maximum and minimum zoom level.
|
|
|
|
### `webFrame.setSpellCheckProvider(language, autoCorrectWord, provider)`
|
|
|
|
* `language` String
|
|
* `autoCorrectWord` Boolean
|
|
* `provider` 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][spellchecker] as provider:
|
|
|
|
```javascript
|
|
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,
|
|
allows registering ServiceWorker and supports fetch API.
|
|
|
|
### `webFrame.insertText(text)`
|
|
|
|
* `text` String
|
|
|
|
Inserts `text` to the focused element.
|
|
|
|
### `webFrame.executeJavaScript(code[, userGesture])`
|
|
|
|
* `code` String
|
|
* `userGesture` Boolean (optional) - Default is `false`.
|
|
|
|
Evaluates `code` in page.
|
|
|
|
In the browser window some HTML APIs like `requestFullScreen` can only be
|
|
invoked by a gesture from the user. Setting `userGesture` to `true` will remove
|
|
this limitation.
