252 </p> | |
253 <h2 id="manifest">Manifest</h2> | |
254 <p> | |
255 You must declare the "privacy" permission in your extension's | |
256 <a href="manifest.html">manifest</a> to use the API. For example: | |
257 </p> | |
258 <pre>{ | |
259 "name": "My extension", | |
260 ... | |
261 <b>"permissions": [ | |
262 "privacy" | |
263 ]</b>, | |
264 ... | |
265 }</pre> | |
266 <h2 id="usage">Usage</h2> | |
267 <p> | |
268 Reading the current value of a Chrome setting is straightforward. You'll first | |
269 need to find the property you're interested in, then you'll call | |
270 <code>get()</code> on that object in order to retrieve its current value and | |
271 your extension's level of control. For example, to determine if Chrome's | |
272 Autofill feature is enabled, you'd write: | |
273 </p> | |
274 <pre>chrome.privacy.services.autofillEnabled.get({}, function(details) { | |
275 if (details.value) | |
276 console.log('Autofill is on!'); | |
277 else | |
278 console.log('Autofill is off!'); | |
279 });</pre> | |
280 <p> | |
281 Changing the value of a setting is a little bit more complex, simply because | |
282 you first must verify that your extension can control the setting. The user | |
283 won't see any change to her settings if your extension toggles a setting that | |
284 is either locked to a specific value by enterprise policies | |
285 (<code>levelOfControl</code> will be set to "not_controllable"), or if another | |
286 extension is controlling the value (<code>levelOfControl</code> will be set to | |
287 "controlled_by_other_extensions"). The <code>set()</code> call will succeed, | |
288 but the setting will be immediately overridden. As this might be confusing, it | |
289 is advisable to warn the user when the settings they've chosen aren't | |
290 practically applied. | |
291 </p> | |
292 <p class="note"> | |
293 Full details about extensions' ability to control <code>ChromeSetting</code>s | |
294 can be found under | |
295 <a href="types.html#ChromeSetting"> | |
296 <code>chrome.types.ChromeSetting</code></a>. | |
297 </p> | |
298 <p> | |
299 This means that you ought to use the <code>get()</code> method to determine | |
300 your level of access, and then only call <code>set()</code> if your extension | |
301 can grab control over the setting (in fact if your extension can't control the | |
302 setting it's probably a good idea to visually disable the functionality to | |
303 reduce user confusion): | |
304 </p> | |
305 <pre>chrome.privacy.services.autofillEnabled.get({}, function(details) { | |
306 if (details.levelOfControl === 'controllable_by_this_extension') { | |
307 chrome.privacy.services.autofillEnabled.set({ value: true }, function() { | |
308 if (chrome.extension.lastError === undefined) | |
309 console.log("Hooray, it worked!"); | |
310 else | |
311 console.log("Sadness!", chrome.extension.lastError); | |
312 } | |
313 } | |
314 });</pre> | |
315 <p> | |
316 If you're interested in changes to a setting's value, add a listener to its | |
317 <code>onChange</code> event. Among other uses, this will allow you to warn the | |
318 user if a more recently installed extension grabs control of a setting, or if | |
319 enterprise policy overrides your control. To listen for changes to Autofill's | |
320 status, for example, the following code would suffice: | |
321 </p> | |
322 <pre>chrome.privacy.services.autofillEnabled.onChange.addListener( | |
323 function (details) { | |
324 // The new value is stored in `details.value`, the new level of control | |
325 // in `details.levelOfControl`, and `details.incognitoSpecific` will be | |
326 // `true` if the value is specific to Incognito mode. | |
327 });</pre> | |
328 <h2 id="examples">Examples</h2> | |
329 <p> | |
