I have a page similar to the above google places autocomplete demo url whereby if i type Buckingham Palace. It will return results of
Buckingham Palace Road, London, United Kingdom
Buckingham Palace Shop, Buckingham Palace Road, Victoria, London,
United Kingdom
and etc. How do i remove London, United Kingdom from the results?
It seems Google have no interest in sorting it out anytime soon. I have had to resort to the following, might be sufficient for others' needs as well:
document.addEventListener('DOMNodeInserted', function(event) {
var target = $(event.target);
if (target.hasClass('pac-item')) {
target.html(target.html().replace(/, Australia<\/span>$/, "</span>"));
}
});
note that pac-item is the class used on each suggestion. See Google Reference for other classes used. The container with pac-container class seems to drop the items when it is not shown and add new ones when it displays so if these pac-items are getting added to the DOM, it means suggestions are on their way to be displayed and pac-container is about to become visible.
just worked this out so open to improvements.
This also is not a complete solution. When selecting a suggestion with the country removed, autocomplete still adds the country to the geocoding! place_changed is too late a stage to change that so please see the solution above as only part of the answer. I'll update this again once I figure out the rest.
--- update
personally, i ended up not using the google autocomplete at all as i couldn't find a way around the problem of the autocomplete still showing the country once a modified suggestion is selected. a more usable approach was to use twitter typeahead and use the google APIs for getting the suggestions only. this gave me more control over the suggestions but obviously requires more manual work to make up for lost functionality
Here is How I made it work with jQuery auto-complete. Hope it helps someone.
$("#Search").autocomplete({
source: function (request, response) {
var options = {
input: request.term,
types: ['(cities)'],
region: 'US',
componentRestrictions: { country: "us" }
};
function callback(predictions, status) {
for (var i = 0, prediction; prediction = predictions[i]; i++) {
results.push(prediction.description.replace(/, United States$/, ""));
}
response(results);
}
var service = new google.maps.places.AutocompleteService();
service.getPlacePredictions(options, callback);
var results = [];
}
});
This is not possible without manually processing the results. If you think that it would be a useful feature, please file a Places API - Feature Request.

I am trying to get the reaction count for each content using the Github v4 API (GraphQL). Can anyone suggest how can I achieve this?
Github supports the following reactions:
THUMBS_UP
THUMBS_DOWN
LAUGH
HOORAY
CONFUSED
HEART
ROCKET
EYES
For each reaction, I want a count which denotes the number of people who reacted. For eg. I am referring to this comment -> #2190.
Github API provides a feature called reaction group. Refer to the following query...
{
repository(owner: "sindresorhus", name: "refined-github") {
issue(number: 2190) {
reactionGroups {
content
users {
totalCount
}
}
}
}
}
Hope this solves your problem!
This might not be the question but it was the list of doubts which comes when learning native script from scratch.
I had a 1000 or more list of data stored in data table. know i want to display it on a list view but i don't want to read all the data at once. because i have images stored in other directory and want to read that also. So, for 20 to 30 data's the performance is quite good. but for 1000 data it is taking more than 15 minutes to read the data as well as images associated with it. since i'm storing some high quality images.
Therefore i decided to read only 20 data's with their respective images. and display it on list. know when user reaches the 15th data of the list. i decided to read 10 more data from the server.
know when i search this i came across "RadListView Load on Demand".
then i just looked at the code below.
public addMoreItemsFromSource(chunkSize: number) {
let newItems = this._sourceDataItems.splice(0, chunkSize);
this.dataItems.push(newItems);
}
public onLoadMoreItemsRequested(args: LoadOnDemandListViewEventData) {
const that = new WeakRef(this);
const listView: RadListView = args.object;
if (this._sourceDataItems.length > 0) {
setTimeout(function () {
that.get().addMoreItemsFromSource(2);
listView.notifyLoadOnDemandFinished();
}, 1500);
args.returnValue = true;
} else {
args.returnValue = false;
listView.notifyLoadOnDemandFinished(true);
}
}
In nativescript if i want to access binding element xml element. i must use observables in viewmodel or exports.com_name on associated js file.
but in this example it is started with public..! how to use this in javascript.
what is new WeakRef(this) ?
why it is needed ?
how to identify user has scrolled to 15 data, as i want to load more data when he came at 15th data.
after getting data how to update array of list and show it in listview ?
Finally i just want to know how to use load on demand
i tried to create a playground sample of what i have tried but it is giving error. it cannot found module of radlistview.
Remember i'm a fresher So, kindly keep this in mind when answering. thank you,
please modify the question if you feel it is not upto standards.
you can check the updated answer here
https://play.nativescript.org/?template=play-js&id=1Xireo
TypeScript to JavaScript
You may use any TypeScript compiler to convert the source code to JavaScript. There are even online compilers like the official TypeScript Playground for instance.
In my opinion, it's hard to expect ES5 examples any more. ES6-9 introduced a lot of new features that makes JavaScript development much more easier and TypeScript takes JavaScript to next level, interpreter to compiler.
To answer your question, you will use the prototype chain to define methods on your class in ES5.
YourClass.prototype.addMoreItemsFromSource = function (chunkSize) {
var newItems = this._sourceDataItems.splice(0, chunkSize);
this.dataItems.push(newItems);
};
YourClass.prototype.onLoadMoreItemsRequested = (args) {
var that = new WeakRef(this);
var listView = args.object;
if (this._sourceDataItems.length > 0) {
setTimeout(function () {
that.get().addMoreItemsFromSource(2);
listView.notifyLoadOnDemandFinished();
}, 1500);
args.returnValue = true;
} else {
args.returnValue = false;
listView.notifyLoadOnDemandFinished(true);
}
}
If you are using fromObject syntax for your Observable, then these functions can be passed inside
addMoreItemsFromSource: function (chunkSize) {
....
};
WeakRef: It helps managing your memory effiencetly by keeping a loose reference to the target, read more on docs.
How to load more:
If you set loadOnDemandMode to Auto then loadMoreDataRequested event will be triggered whenever user reaches the end of scrolling.
loadOnDemandBufferSize decides how many items before the end of scroll the event should be triggered.
Read more on docs.
How to update the array:
That's exactly what showcased in addMoreItemsFromSource function. Use .push(item) on the ObservableArray that is linked to your list view.
I'm planning on having multiple ace editor instances on a page and I'd like to know if the core libraries are keeping track of them so I can easily get a reference to them later.
If not, would keeping the editor instances in a dictionary or object be a good way to do it? Could I create an object on the ace class and should they be by reference or id?
var editor1 = ace.edit("myEditorDivID");
var editor2 = ace.edit("myEditorDivID2");
var editors = ace.editors;
console(editor1==editors["myEditorDivID"]); // true
console.log(editors["myEditorDivID"]); // editor1
var editorIds = ace.editorIds;
console.log(editorIds[0]); // myEditorDivID
And is there an ace destroy method that should be used to remove references to these instances?
Nevermind on part two of this question. I just found the destroy methods:
editor.destroy();
editor.container.remove();
Update:
I just thought of something else. If we can keep track of the id's or references we can prevent same id collisions. It can also help track how many editors are on a page or if multiple are being created by accident.
I just looked at the ace source and don't see anything keeping track of the editors as they are created. Should I try to whip something up or let someone else tackle it?
Update 2:
I'm thinking to add an editors property and set it by id. I've added an answer with a suggestion.
Answering my own question, no, it does not. But I suggest the following Pseudo code:
ace.addEditorById = function (id, editor) {
if (ace.editors[id]!=null) throw Error ("Editor already created");
ace.editors[id] = editor;
}
ace.getEditorById = function (id) {
return ace.editors[id];
}
ace.removeEditorById = function (id) {
var editor = ace.editors[id];
if (editor) {
editor.destroy();
editor.container.remove();
delete ace.editors[id];
}
}
ace.editors = {};
// then when I create an editor I use the following code:
editor = ace.edit("editor1");
ace.addEditorById(editor);
editor2 = ace.edit("editor2");
ace.addEditorById(editor2);
Maybe the editor can be added in the edit call. What do you think?
I can get room's clients list with this code in socket.io 0.9.
io.sockets.clients(roomName)
How can I do this in socket.io 1.0?
Consider this rather more complete answer linked in a comment above on the question: https://stackoverflow.com/a/24425207/1449799
The clients in a room can be found at
io.nsps[yourNamespace].adapter.rooms[roomName]
This is an associative array with keys that are socket ids. In our case, we wanted to know the number of clients in a room, so we did Object.keys(io.nsps[yourNamespace].adapter.rooms[roomName]).length
In case you haven't seen/used namespaces (like this guy[me]), you can learn about them here http://socket.io/docs/rooms-and-namespaces/ (importantly: the default namespace is '/')
Updated (esp. for #Zettam):
checkout this repo to see this working: https://github.com/thegreatmichael/socket-io-clients
Using #ryan_Hdot link, I made a small temporary function in my code, which avoids maintaining a patch. Here it is :
function getClient(roomId) {
var res = [],
room = io.sockets.adapter.rooms[roomId];
if (room) {
for (var id in room) {
res.push(io.sockets.adapter.nsp.connected[id]);
}
}
return res;
}
If using a namespace :
function getClient (ns, id) {
return io.nsps[ns].adapter.rooms[id]
}
Which I use as a temporary fix for io.sockets.clients(roomId) which becomes findClientsSocketByRoomId(roomId).
EDIT :
Most of the time it is worth considering avoiding using this method if possible.
What I do now is that I usually put a client in it's own room (ie. in a room whose name is it's clientID). I found the code more readable that way, and I don't have to rely on this workaround anymore.
Also, I haven't tested this with a Redis adapter.
If you have to, also see this related question if you are using namespaces.
For those of you using namespaces I made a function too that can handle different namespaces. It's quite the same as the answer of nha.
function get_users_by_room(nsp, room) {
var users = []
for (var id in io.of(nsp).adapter.rooms[room]) {
users.push(io.of(nsp).adapter.nsp.connected[id]);
};
return users;
};
As of at least 1.4.5 nha’s method doesn’t work anymore either, and there is still no public api for getting clients in a room. Here is what works for me.
io.sockets.adapter.rooms[roomId] returns an object that has two properties, sockets, and length. The first is another object that has socketId’s for keys, and boolean’s as the values:
Room {
sockets:
{ '/#vQh0q0gVKgtLGIQGAAAB': true,
'/#p9Z7l6UeYwhBQkdoAAAD': true },
length: 2 }
So my code to get clients looks like this:
var sioRoom = io.sockets.adapter.rooms[roomId];
if( sioRoom ) {
Object.keys(sioRoom.sockets).forEach( function(socketId){
console.log("sioRoom client socket Id: " + socketId );
});
}
You can see this github pull request for discussion on the topic, however, it seems as though that functionality has been stripped from the 1.0 pre release candidate for SocketIO.
Is it possible to use nsISelectionController to watch when a a highlight/selection is made?
I know that there are different selection scopes. I want to watch when a user makes a selection in the default scope seen at MXR - nsISelectionController Constants.
Kind of like an addEventListener on select change but on the text nodes of the document.
Thanks
I found a solution but it doesn't use nsIController as #Neil had recommended in a SO topic HERE to look at viewSource.js.
Im still interested in a nsIController solution if possible, im trying to understand that sucker it confuses me.
So this is how you observer for a selection:
var mylis = {
timeout: 0,
notifySelectionChanged: function(doc, sel, reason)
{
if (!this.timeout) {
this.timeout = setTimeout(function() {
console.log('notifySelectionChanged','doc=',doc,'sel=',sel,'reason=',reason);
mylis.timeout = 0;
}, 1000);
}
}
}
gBrowser.contentWindow.getSelection().QueryInterface(Ci.nsISelectionPrivate).addSelectionListener(mylis);
//gBrowser.contentWindow.getSelection().QueryInterface(Ci.nsISelectionPrivate).removeSelectionListener(mylis);
the timeout is important because otherwise it will slow down the browser thread. you can see as you highlight its all gimicky. viewSource.js used 100ms so I would reocmmend that.
MXR - viewSource.js
