This is kind of an update to a question I asked earlier but never got an answer here previous question. I've got a google map that creates and loads different categories of markers from an xml file when the corresponding checkbox is clicked and then updates the list on a sidebar. I'd like to load each category into its own separate sidebar so I can split them up or stack them side-by-side, etc. When I click the check-boxes the first list (the list of huts) gets loaded into both sidebars but the second list (list of yurts) gets loaded correctly into its corresponding sidebar. I don't understand why one list gets loaded into both sidebars but the other list gets loaded correctly into just one. Thanks in advance for any help. The code is all below:
Javascript

Your makeSidebar function has an issue (it is doing what you coded it to do, which is the behavior you are seeing):
function makeSidebar() {
var html = "";
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].getVisible()) {
html += '<a href="javascript:myclick(' + i + ')" onmouseover="gmarkers['+ i +'].setAnimation(google.maps.Animation.BOUNCE)" onmouseout="gmarkers['+ i +'].setAnimation(null)">' + gmarkers[i].myname + '<\/a><br>';
}
document.getElementById(gmarkers[i].mycategory+"side_bar").innerHTML = html;
}
}
If you want unique text for each "sidebar", you should make a unique version of "html" for each sidebar. Something like this:
var html = null;
function makeSidebar() {
// empty any pre-existing sidebar entries
for (i in html) {
document.getElementById(i+"side_bar").innerHTML = "";
}
html = []; // make html an array
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].getVisible()) {
// make entry for category if it doesn't already exist
if (!html[gmarkers[i].mycategory])
html[gmarkers[i].mycategory] = "";
// add the entry to the sidebar specific to the category
html[gmarkers[i].mycategory] += '<a href="javascript:myclick(' + i + ')" onmouseover="gmarkers['+ i +'].setAnimation(google.maps.Animation.BOUNCE)" onmouseout="gmarkers['+ i +'].setAnimation(null)">' + gmarkers[i].myname + '<\/a><br>';
}
}
for (i in html) {
document.getElementById(i+"side_bar").innerHTML = html[i];
}
}

I have a project that is making webgis to display data on a map and a check box to display data or hide that data.
I have finished making it with the google map version, but because it is paid, I look for the free version using leaflets.
But I have a problem with the check box on the leaflet, after unchecking, the marker does not disappear.
var date = new Date();
var year = date.getFullYear();
// Center of the map
var center = [-1.1329372, 120.0350916];

var map = L.map("map").setView(center, 5);
// Set up the Google Map Hybrib layer

} else {
$('.leaflet-pane img[src="'+type+'.png"]').hide();
}

I am making a map and I want to use the value from the database to be used as the coordinates in the javascript. Please see below:
I want to change the default values of the longitude and latitude by fetching data fro the database but I don't know how.

I trying to do the map base on geocodezip example http://www.geocodezip.com/geoxml3_test/v3_FusionTables_CountryBrowser.html , but I have always have message on my map "Data may still be loading".
I reduce my map to only 10 polygons but I have same message over and over.
Inside left sidebar; name of the polygons are properly displayed, and when I click "show" map guide me to the exact place of the polygon, but the polygons are not displayed on the map. Does anyone have any suggestions?

With the new encrypted ids, you need to use the new query syntax:
layer.setQuery({select:'geometry',from:FT_TableID,where:"'name_0' = '"+CountryName+"'"});
layer.setQuery({select:'geometry',from:FT_TableID,where:"'name_0' = '"+CountryName+"' AND 'name' = '"+gpolygons[id].name+"'"});
and most important (if you only want the selected polygons to show):
layer = new google.maps.FusionTablesLayer(FT_Options);
The old "string" queries only seem to work with the numeric IDs.
working example
updated original example with new syntax
See answer above, it works for me. Thanks to geocodezip
Non numric fields should be enclosed in single quotes under double quotes, ex: " SELECT 'DATE' <= '2013-11-11' "
For complete example, you can have a look here.
The code below works great in Firefox and Safari, no issues. In IE, the markers don't load at all and in Chrome, the markers load but when you click on a marker, the infobox does not pop up. If you click in on the side menu it does pop up. Any ideas? Here is the code:

The error message I get in IE (9) is:
XML5617: Illegal XML character.
, line 7858 character 243
hike_points_of_interest="Arguably the prettiest trail in the Loch Raven Reservoir watershed. Follow it to Merryman Point, where the reservoir spreads out in several directions. From the parking area, you have several options to begin the hike�the trailhead farthest to the right leads to a narrow path that runs alongside the reservoir, the farthest to the left runs to a fire road, and the second to the left (the one I take) runs along a wide path but not before going along a narrower path, which will eventually afford nice views of the reservoir and give you the option of linking with the fire road."
I am currently working on a fairly basic phone gap applications. On one page I populate a listview from a JSON object. It populates fine and I am able to click on the list to go to the next page. The problem arises when I click the android back button (this takes you back to the previous page), the content that was loaded has no disappeared. As far as I can tell the DOM element disappears as soon as the new page is loaded (however i am new to this technology so I could be wrong).
