Geolocation.getCurrentPosition() - Web APIs
the geolocation.getcurrentposition() method is used to get the current position of the device.
... syntax navigator.geolocation.getcurrentposition(success[, error[, [options]]) parameters success a callback function that takes a geolocationposition object as its sole input parameter.
...highaccuracy: true, timeout: 5000, maximumage: 0 }; function success(pos) { var crd = pos.coords; console.log('your current position is:'); console.log(`latitude : ${crd.latitude}`); console.log(`longitude: ${crd.longitude}`); console.log(`more or less ${crd.accuracy} meters.`); } function error(err) { console.warn(`error(${err.code}): ${err.message}`); } navigator.geolocation.getcurrentposition(success, error, options); specifications specification status comment geolocation api recommendation initial specification.

PR_GetCurrentThread
syntax #include <prthread.h> prthread* pr_getcurrentthread(void); returns always returns a valid reference to the calling thread--a self-identity.
... description the currently running thread may discover its own identity by calling pr_getcurrentthread.

Using the Geolocation API - Web APIs
you can test for the presence of geolocation thusly: if('geolocation' in navigator) { /* geolocation is available */ } else { /* geolocation is not available */ } getting the current position to obtain the user's current location, you can call the getcurrentposition() method.
... note: by default, getcurrentposition() tries to answer as fast as possible with a low accuracy result.
...devices with a gps, for example, can take a minute or more to get a gps fix, so less accurate data (ip location or wifi) may be returned to getcurrentposition().

Capabilities, constraints, and settings - Web APIs
this display is updated by the function getcurrentsettings(), which gets the current settings for the audio and video tracks and inserts the corresponding code into the tracks' settings display boxes by setting their value.
... function getcurrentsettings() { if (videotrack) { videosettingstext.value = json.stringify(videotrack.getsettings(), null, 2); } if (audiotrack) { audiosettingstext.value = json.stringify(audiotrack.getsettings(), null, 2); } } this gets called after the stream first starts up, as well as any time we've applied updated constraints, as you'll see below.
...etaudiotracks(); let videotracks = stream.getvideotracks(); videoelement.srcobject = stream; if (audiotracks.length) { audiotrack = audiotracks[0]; } if (videotracks.length) { videotrack = videotracks[0]; } }).then(function() { return new promise(function(resolve) { videoelement.onloadedmetadata = resolve; }); }).then(function() { getcurrentsettings(); }).catch(handleerror); } there are several steps here: it calls buildconstraints() to create the mediatrackconstraints objects for the two tracks from the code in the edit boxes.
... when that happens, we know the video has started playing, so we call our getcurrentsettings() function (described above) to display the actual settings that the browser decided upon after considering our constraints and the capabilities of the hardware.

Add to iPhoto
if (document.getelementbyid("contentareacontextmenu")) { document.getelementbyid("contentareacontextmenu").addeventlistener("popupshowing", iphoto.onpopup, false); } responding when the context menu is clicked when the user right-clicks an image, our handler gets called: onpopup: function() { var node = iphoto.getcurrentnode(); var item = document.getelementbyid("add-to-iphoto_menuitem"); if (item) { item.hidden = (node == null); // hide it if we're not on an image } } this code finds the image node the user right-clicked in by calling our getcurrentnode() method, then sets the hidden state of the "add image to iphoto" menu item based on whether or not an image node was found.
... the code to identify the node looks like this: getcurrentnode: function() { var node = document.popupnode; // if no node, just return null now if (node == undefined || !node) { return null; } // is it an image node?
... add: function() { var node = iphoto.getcurrentnode(); if (node) { var src = node.getattribute("src"); // get the url of the image if (src && src != "") { iphoto.addimagebyurl(src); } } } this fetches the node representing the image the user wants to add, and, if it's an image, fetches the image's url from its src attribute, then passes it into our addimagebyurl() method, which will do all the heavy lifting.

Implementing feature detection - Learn web development
therefore, you can detect whether the browser supports geolocation or not by using something like the following: if ("geolocation" in navigator) { navigator.geolocation.getcurrentposition(function(position) { // show the location on a map, perhaps using the google maps api }); } else { // give the user a choice of static maps instead perhaps } it is probably better to use an established feature detection library however, rather than writing your own all the time.
... finally, add another <script> element at the bottom of the html body (just before the </body> tag), and put the following script inside the tags: if (modernizr.geolocation) { navigator.geolocation.getcurrentposition(function(position) { let latlng = new google.maps.latlng(position.coords.latitude,position.coords.longitude); let myoptions = { zoom: 8, center: latlng, maptypeid: google.maps.maptypeid.terrain, disabledefaultui: true } let map = new google.maps.map(document.getelementbyid("map_canvas"), myoptions); }); } else { const para = document.createele...
