get instance of map in jquery ui map - jquery-ui

i want to make the markers clustered with markerClusterer but i cannot get the map instance with jquery ui map . js
tried:
var map = $('#map_canvas').gmap('getMap');
or
var map = $('map_canvas').gmap('get', 'map');
and after:
var markerCluster = new MarkerClusterer(map, allMarkers);
but with errors
Thank you

Tried this . No Errors but no clusters...
$('#map_canvas').gmap({ 'callback': function () {
var self = this;
$.getJSON('Data/markers.json', function (data) {
$.each(data.markers, function (i, marker) {
self.addMarker({ 'position': new google.maps.LatLng(marker.latitude,marker.longitude)}).click(function () {
$.ajax({
type: "GET",
url: "/LocoMap/LocoMap/InfoMobilePartialView/",
data: { latitude: marker.latitude, longitude: marker.longitude},
success: function (data) {
$("#marker-info").remove();
$(document.body).append("<div id='marker-info' data-role ='page'> </div>");
var $contentDiv = $("#marker-info");
$contentDiv.html(data).trigger('create');
$.mobile.changePage("#marker-info", { changeHash: false, type: "get", transition: 'pop',rel:"external" });
},
error: function (errorData) { onError(errorData); }
});
});
});
});
self.set('MarkerClusterer', new MarkerClusterer(this.get('map'), this.get('markers')));
}});

$('#map_canvas').gmap({'zoom': 2, 'disableDefaultUI':true}).bind('init', function(evt, map) {
$.getJSON( 'Data/markers.json', function(data) {
$.each( data.markers, function(i, m)
$('#map_canvas').gmap('addMarker', { 'position': new google.maps.LatLng(m.latitude, m.longitude), 'bounds':true } );
});
});
$('#map_canvas').gmap('set', 'MarkerClusterer', new MarkerClusterer(map,$(this).gmap('get', 'markers')));
});
with no errors and no clusters
it seems **$(this).gmap('get', 'markers')));** returns Array[0]

why the function in side of function wont get called?

i have the following reactjs code to generate two dropdown list where the ddlproducts gets loaded by ddlCategories selection. but when i called the function getDataById() and tried to print the ajax populated array data2 to alert(), there was no alert() there were two alerts none of the alerts were prompted. it shown this error message on the IE console,
execution did not reached the function getDataById() 'cus the alert() in that function even didn't execute
SCRIPT438: Object doesn't support property or method 'getDataById'
correction: once the calling of this.props.getDataById() was changed to this.getDataById() it worked
but how do populate the ddlProducts dropdown. how do i access tag of the ddlProducts and then add the options to it?
here is the code:
var gdata=[];
var trStyle = {
'color': 'black',
'border-style' :'solid',
'margin-left':'20%'
};
var HCOMP = React.createClass({
getInitialState:function(){
return{data1:[], data2:[], isMounted:false, selectedValue:0}
},
componentDidMount:function(){
this.getData();
this.setState({isMounted:true})
},
ddlProdCatsChanegeEvent: function(e) {
if (this.state.isMounted)
{
var newV = ReactDOM.findDOMNode(this.refs.refProdCats).value;
var seleValue = newV;
this.setState({selectedValue:newV}, function(){
this.getDataById(this.state.selectedValue);
alert(this.state.data2);
});
}
},
render: function() {
var prodCats = this.state.data1.map(function(ele, index){// <PRODCATSOPTION optValue={ele.ProductCategoryID} optText={ele.Name} />
return <option value={ele.ProductCategoryID} data-key={index}>{ele.Name}</option>
});
prodCats.unshift(<option value={''}>{'---- select category ------'}</option>)
return (<div>Prodcut Category:<br /><select id="ddlCategories" ref="refProdCats" onChange={this.ddlProdCatsChanegeEvent}>{prodCats}</select><br />
Products:<br /><select id="ddlPorducts" ref="refProds"></select><br /></div>
)
},
getDataById:function(catId){
var x = catId;
alert('rec id:'+x);
$.ajax({
url:'http://localhost:53721//Home/GetProductCats?id='+ x,
method:'GET',
success:function(d1){
this.setState({data2:d1});
}.bind(this),
error:function(){
alert('ERROR');
}.bind(this)
})
},
getData:function(){
//ajax here
$.ajax({
url:'http://localhost:53721//Home/GetProductCats',
method:'GET',
success:function(d1){
this.setState({data1:d1});
}.bind(this),
error:function(){
alert('ERROR');
}.bind(this)
})
}
});
var PRODOPTIONS = React.createClass({
render:function(){
return(<option value={this.props.optValue}>{this.props.optText}</option> )
}
});
var PRODCATSOPTION = React.createClass({
render:function(){
return(<option value={this.props.optValue}>{this.props.optText}</option> )
}
});
ReactDOM.render( <HCOMP/>, document.getElementById('d1') );
Try updating ddlProdCatsChanegeEvent to ddlPropCatsChangeEvent.

Jquery Autocomplete in mvc if user types text which is not in autocomplete list

Jquery Autocomplete UI in mvc .. If user enter some text which is not in list it should alert not in list ....
In View:-
$("#loc").autocomplete({
source: function (request, response) {
$.ajax({
url: "/a/AutoLoc",
type: "POST",
dataType: "json",
data: { term: request.term },
success: function (data) {
if (data.length == 0) {
alert('Please select an item from the list');
document.getElementById('Loc').value = "";
document.getElementById('Loc').focus();
document.getElementById('Loc').style.border = "solid 1px red";
}
else
response($.map(data, function (item) {
document.getElementById('Location').style.border = "solid 1px black";
return { label: item.Name, value: item.Name, id: item.LocationId };
}));
}
})
},
select: function (event, ui) {
$("#locationID").val(ui.item.id);
}
});
in Controller:
public JsonResult AutoLoc(string term)
{
var result = (from r in db.S
where r.Name.ToLower().Contains(term.ToLower())
select new { r.Name, r.id }).Distinct();
return Json(result, JsonRequestBehavior.AllowGet);
}
Here suppose we enter 'a' then it will not alert any message . Though 'a' is not in list
when we enter any character which is not in autocomplete list it should alert and make that box as red.
Actually What is happening in 'data' we are getting values because in controller we are writing a query as contains or startwith 'a' so value is returned but as a individual 'a' is not in list that starts with or contains 'a'.
Try this:
$("#loc").autocomplete({
source: function(request, response) {
$.ajax({
url: "/a/AutoLoc",
type: "POST",
dataType: "json",
data: {term: request.term},
success: function(data) {
var found = $.map(data, function(item) {
return {label: item.Name, value: item.Name, id: item.LocationId};
});
if (found.length === 0) {
alert('Please select an item from the list');
$("#loc").val("");
$('#loc').focus();
$('#loc').css("border", "solid 1px red");
} else {
$('#loc').css("border", "none");
}
response(found);
}
});
},
select: function(event, ui) {
$("#locationID").val(ui.item.id);
}
});
In View:
$("#loc").autocomplete({
source: function (request, response) {
$.ajax({
url: "/a/AutoLoc",
type: "POST",
dataType: "json",
data: {term: request.term},
success: function(data) {
var found = $.map(data, function(item) {
return {label: item.Name, value: item.Name, id: item.LocationId};
});
}
});
},
change: function (event, ui) {
var referenceValue = $(this).val();
var matches = false;
$(".ui-autocomplete li").each(function () {
if ($(this).text() == referenceValue) {
matches = true;
return false;
}
});
if (!matches) {
alert('Please select an item from the list');
this.value = "";
this.focus();
this.style.border = "solid 1px red";
}
else {
document.getElementById("submitbutton").disabled = false;
this.style.border = "solid 1px black";
}
}
});
Now when we type 'a' it will alert and show the box border in red color......
This is what i wanted....

jquery smartAutocomplete with infinite scroll

how we can have autocomplete combo with infinit scroll?
i found an autocomplete jquery ui with infinit scroll, but this autocomplete gets data by pagemethods. but i want to use it in mvc application and want to use an action of a controller to retrieving data.
to use this autocomplete by pagemethods should do this:
$(document).ready(function () {
//Input for testing purposes
$("#inp").smartautocomplete({
getDataFunc: getData,
pageSize: 15,
autoFocus: true
});
});
//Function the SA plugin called when data is needed.
var getData = function (input, pageIndex, pageSize, callback) {
PageMethods.GetData(input, pageIndex, pageSize, function (response) {
if (response) {
response = $.map(response, function (item) {
return {
label: item,
value: item
}
});
callback(response);
}
else callback();
});
};
but i change the way of getting data by using $.ajax:
var getData = function (input, pageIndex, pageSize, callback) {
$.getJSON(
{ url: '#Url.Action("GetData", "Home")' },
{ input: input, pageIndex: pageIndex, pageSize: pageSize },
function (response) {
if (response) {
response = $.map(response, function (item) {
return {
label: item,
value: item
};
});
callback(response);
}
else callback();
});
};
but it does not work, and the action does not called.
this autocomplete is accessible here:
http://www.codeproject.com/Articles/325719/JQueryUI-smartAutocomplete?fid=1683905
i want to know if there is any other solution to have autocomplete with infinit scroll
Replace PageMethod call with AJAX call
$.ajax({
url: '#Url.Action("GetData", "Default")',
type: 'GET',
dataType: 'json',
data: {
input: input,
pageIndex: pageIndex,
pageSize: pageSize
},
success: function (response) {
//alert(response);
if (response) {
response = $.map(response, function (item) {
return { label: item, value: item };
});
callback(response);
} else {
callback();
}
},
error: function (e) {
alert('error' + e);
},
contentType: 'application/json; charset=utf-8'
});
Make sure your controller action is returning JSONResult
return new JsonResult {JsonRequestBehavior = JsonRequestBehavior.AllowGet, Data = data };//new {result = data}
Hope this helps.

Linked jQuery sortable lists and Backbone collections

I'm still finding my way with Backbone and I've always use Prototype instead of jQuery in the past so please forgive me if I'm doing something stupid.
I'm trying to develop a UI containing several connected unordered lists where each sortable list is represented by a separate Backbone collection. I'm using ICanHaz and Mustache templates but that's not of importance for my question.
When dragging items between the lists, how would I best achieve the automatic updating of the collections (remove a model from one and insert it into another)? I'm currently trying to use the receive and remove methods in the jQueryUI Sortable interaction — am I at least on the right lines?
var WS = {};
(function(ns) {
ns.Item = Backbone.Model.extend();
ns.Content = Backbone.Collection.extend({
model: ns.Item,
url: location.href,
initialize: function(el) {
this.el = $(el);
this.deferred = this.fetch();
},
recalculate: function() {
var count = this.length;
this.el.next(".subtotal").html(count);
},
setOrder: function() {
$.ajax({
url: this.url + "/reorder",
type: "POST",
data: "tasks=" + $(this.el).attr("id") + "&" + this.el.sortable("serialize")
});
}
});
ns.ContentRow = Backbone.View.extend({
tagName: "li",
className: "item",
events: {
"click .delete": "destroy"
},
initialize: function(options) {
_.bindAll(this, "render", "destroy");
this.model.bind("change", this.render);
this.model.view = this;
},
render: function() {
var row = ich.item(this.model.toJSON());
$(this.el).html(row);
return this;
},
destroy: function() {
if (confirm("Really delete?")) {
this.model.destroy({
success: function(model, response) {
$(model.view.el).remove();
},
error: function(model, response) {
console.log(response);
}
});
}
}
});
ns.ListView = Backbone.View.extend({
initialize: function(collection) {
this.el = collection.el;
this.collection = collection;
this.collection.bind("add", this.addOne, this);
_.bindAll(this, "addOne");
this.el.sortable({
axis: "y",
connectWith: ".tasks",
receive: _.bind(function(event, ui) {
// do something here?
}, this),
remove: _.bind(function(event, ui) {
// do something here?
}, this),
update: _.bind(function(event, ui) {
var list = ui.item.context.parentNode;
this.collection.setOrder();
}, this)
});
},
insert: function(item) {
var prefix = this.el.parentsUntil('ul').parent().attr("id"),
view = new ns.ContentRow({
model: item,
id: prefix + "_" + item.id
});
this.el.append(view.render().el);
},
addOne: function(item) {
if (item.isNew()) {
item.save({}, {
success: _.bind(function(model, response) {
// I should set id from JSON response when live
model.set({ id: this.collection.length });
this.insert(model);
}, this)
});
} else {
this.insert(item);
}
},
addAll: function() {
this.collection.each(this.addOne);
},
render: function() {
this.collection.deferred.done(_.bind(function() {
this.addAll();
}, this));
}
});
ns.AppView = Backbone.View.extend({
lists: [],
initialize: function(holder) {
holder.find("ul").each(_.bind(function(index, list) {
var Items = new WS.Content(list),
App = new WS.ListView(Items);
App.render();
this.lists.push(Items);
}, this));
}
});
})(WS);
$(document).ready(function() {
var App = new WS.AppView($("#tasks"));
});
You are on the right track. You will probably want to add the id of each sortable element into the template somewhere. Then when you receive the event, you know which model to add or remove from the collection. For example add...
<div data-id={{id}}> ... my thing ... </div>
And in the sortable call get the target's id attribute and call Collection.add() or remove()
Just use Backbone.CollectionView.. it has this functionality built in out of the box.
var listView = new Backbone.CollectionView( {
el : $( "#list1" ),
sortable : true,
sortableOptions : {
connectWith : "#list2"
},
collection : new Backbone.Collection
} );
var listView = new Backbone.CollectionView( {
el: $( "#list2" ),
sortable : true,
sortableOptions : {
connectWith : "#list1"
},
collection : new Backbone.Collection
} );
