The below code is to find a location on map, once the location is entered in a textbox.Please note in the below code that I am using 'locator' instead of 'geocoder' as i would like to have custom textbox instead of the textbox provided by the 'esri/dijit/geocoder' and also i would like to get the geocoordinates values using locator.
In the below code, i would like to add 'autocomplete' feature in textbox that has the same functionality as of 'autocomplete' feature in 'geocoder'.

How to add 'autocomplete' feature in this code?
What do you mean by using your own custom textbox provided by esri/dijit/geocoder? The Geocoder dijit comes with default ESRI css to style the dijit, but nothing prevents you from overriding this with your own styles.
For instance you could add a class in your body tag to override the claro styles:
<body class="claro custom">
This way esri dijits will use claro by default, but if you define the same css selectors as the esri dijit and append them with your custom class, the dijit will use that instead. Here's a short example where we override 2 properties of the results element in the Geocoder:
/* Custom styles for the Geocoder dijit */
.custom #myGeocoder .esriGeocoderResults {
overflow: visible;
z-index: 1000 !important;
}
The geocode dijit supports autocomplete using either the default locator or custom ones. Since you are referencing the default locator service you can just use the dijit and pass autoComplete in the options
<script>
var map, geocoder;
require([
"esri/map", "esri/dijit/Geocoder", "dojo/domReady!"
], function(Map, Geocoder) {
map = new Map("map",{
basemap: "gray",
center: [-120.435, 46.159], // lon, lat
zoom: 7
});
geocoder = new Geocoder({
map: map,
autoComplete : true
}, "search");
geocoder.startup();
});
</script>

Try setting the symbol for the flag like icon: L.mapquest.icons.flag({symbol:"08h00"})

What am I doing wrong? The intent is to have a few (say 6) leafletjs panes, each containing many markers and polylines, so the panes can be hidden independently. Here is a simplified program showing just two lines and markers in jsfiddle. The problem is, the polylines all get grouped in the same SVG and all get hidden together. Each pane in the example should show one polyline and one marker.
I don't want to remove the polylines from the map to hide them, then recreating them would not perform well.
If needed, the polylines could be drawn using D3 on top of the leaflet map but I was hoping it could all be done in leaflet.
Thanks!

Using Leaflet and plugins like ListMarkers, I display a list of visible markers on the map. After hovering over the appropriate <li> element in the List, I want the marker popup to be displayed. The <li> element contains various information about the product, unfortunately after hovering over them, the popup appears and disappears. How to make it that if I hover entire <li> element popup will show and not go crazy of each element separately ?
var list = new L.Control.ListMarkers({ layer: markers, itemIcon: null });
list.addTo(map);
list.on('item-mouseover', function(e) {
e.layer.setIcon(L.icon({
iconUrl: '/marker2.png'
}));
e.layer.openPopup();
}).on('item-mouseout', function(e) {
e.layer.setIcon(L.icon({
iconUrl: '/marker.png'
}))
e.layer.closePopup();
});
listaHTML = list.getContainer();
document.getElementById("lista").appendChild(listaHTML);
Seems to be a CSS problem.

I am having lots of problem accessing any objects from a Yahoo Boss YQL Json Response data. I used this YQL Console for Boss Search Tables.
Here is what I have done:
<!DOCTYPE HTML>
<html>
<head>
<script src="http://code.jquery.com/jquery-2.0.3.min.js" type="text/javascript"></script>
<script type="text/javascript">
var url = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20boss.search%20where%20service%20%3D%22images%22%20AND%20count%3D%221%22%20AND%20q%3D%22iphone6%22%20AND%20ck%20%3D%20%22MYCONSUMER_KEY%22%20AND%20secret%3D%22MYCONSUMER_SECRET%22%3B&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
(function showPix()

$.getJSON(url, function (data)
{
console.log(data);
var myObj = data.results.bossresponse.images.results.result.clickurl;
$.each(myObj, function ()

});
});
})();
</script>
</head>
<body>
<div id="pix">
</div>
<button onclick="showPix();">run</button>

The console.log(); gives me one object that contains the image, but I cannot manage to show the image on the screen. And it tells me that showPix is undefined. Any help would be greatly appreciated. TIA
I figured this out as follows:

I'm working on a product that will show information about individual counties in Wisconsin. Is it possible to programmatically write the county's name on the map? The only option I've seen to do this is by creating a tile layer.
I've written a blog post on how to achieve this here: http://rbrundritt.wordpress.com/2012/03/31/label-pushpins-in-bing-maps-v7/
Here is the code sample:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
<script type="text/javascript">
var map = null;
function GetMap()
{
// Initialize the map
map = new Microsoft.Maps.Map(document.getElementById("myMap"),
{
credentials:"YOUR_BING_MAPS_KEY"
});
var labelPin = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(0,0),{
text : 'Custom Label', //The text for the label
typeName : 'labelPin', //Assign a CSS class to the pin
anchor : new Microsoft.Maps.Point(0,0), //Reset the anchor point of the pin to make aligning the text easier.
textOffset : new Microsoft.Maps.Point(-45,0) //Adjust textOffset point for better label positioning
//Adjust the x value as you see fit for better centering of text
});
map.entities.push(labelPin);
}
</script>
<style>
/* Allow div of pushpin to display overflowing content */
.labelPin{
overflow:visible !important;
}
/* Hide the default pushpin, Alternatively point the icon property of the pushpin to a transparent image */
.labelPin img{
display:none;
}
/*Use this to style the text*/
.labelPin div{
white-space:nowrap;
color:blue !important;
}
</style>
</head>
<body onload="GetMap();">
<div id='myMap' style="position:relative; width:800px; height:600px;"></div>
</body>
</html>
Just use a Pushpin with a custom image, and set the custom image to a transparent image, so all you see is the Pushpin text. To make it real easy, you can even specify a base64 encoded transparent image inline directly, as shown below:
var pushpinOptions = {
icon: "data:image/gif;base64,R0lGODlhAQABAIAAAP///////yH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==",/* Transparent 1px x 1px gif with a 1bit palette, created with gimp and encoded with base64 tool in linux.*/
text: 'Your county name goes here',
draggable: false,
visible: true,
};
var pushpin = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(47.6, - 122.33), pushpinOptions);
I am not sure what you are using for the back end but the way I would accomplish this is by doing the following:
ajax call back to the server, get an object that returns the following or something similar
{CountyName = 'Iron', latitude = '23', longitude = -100}
on the call back iterate though that and populate custom info boxes.
