I've been attempting to put together a fusion map that is filterable by a checkbox.
I've used Google's sample code but have clearly gone wrong somewhere.
I'm new to this so I know it's probably a simple mistake but I can't find it.
The checkbox is only working for 1 filter. The others don't work nor does the data linked to them load.
I'd appreciate any help to identify where I've gone wrong.
my data table is at https://www.google.com/fusiontables/DataSource?docid=1VnR1phtvbSUZXPiiVbxiwzOF06sdW_GiZoqd8Ks
and my code is below

You are overwriting ops in the for-condition:
ops = ops[i]
after the first loop the condition will fail, because ops[i] is undefined
Fixed version:
for (var i = 0; i<ops.length,op=ops[i]; ++i) {
if (op.checked) {
var opName = op.value.replace(/'/g, '\\\'');
filter.push("'" + opName + "'");

Google Maps API v3: How to remove all markers?
(32 answers)
Closed 4 years ago.
Could someone be kind enough to share how I can clear the markers in google map before refreshing it with a new set of markers?
In my map, I'm adding markers from an array that contains name, lat and long. The name can be picked from a drop down menu, and then all the markers for that name are added to the page.
Prtoject : Asp.Net Mvc
Link image: https://i.hizliresim.com/V927Py.jpg
When the user adds markers, the previous set of markers remain. I'd like to remove any existing markers before adding the new set.
After reading the documentation, I tried this:

You have to set up an array, where you can store the added marker
var gmarkers = [];
If you add a marker you have to store the marker object in the array.
gmarkers.push(marker);
If you want to remove these markers you can use something like:
function removeMarker() {
if (gmarkers.length > 0) {
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i] != null) {
gmarkers[i].setMap(null);
}
}
}
gmarkers = [];
}

The issue is caused by the error #14, which means that you use strings instead of values. Morever you should split all x/y values (i.e by comma) and push each of them to array. You cannot push the string like '10,20,30'.
for (var i = 0; i < lines.length; i++) {
var itemsX = lines[i].split(','),
itemsY = lines1[i].split(',');
for(var j = 0; j < itemsX.length; j++) {
mySeries.push([parseFloat(itemsX[j]), parseFloat(itemsY[j])]);
}
}
var chart = $('#container').highcharts();

I found several other people on here had the same issue with the Fusion Table Wizard generating HTML that works in the preview but when you try to embed the code on your own webpage pieces are missing. Mine for example, will show the search bar but not the map. Someone else had the same problem and it turned out that quotes were missing around the id number. But mine does have the appropriate quotes. So I'm wondering what is wrong with my code. I've compared my code to theirs several times looking for what is missing but can't figure it out.
Our webpage is hosted by jimdo, and I have to use the html/widget. I copy and paste the code into that. But it does say that some code requires you to edit the head section. That wouldn't be the problem would it? And if it is, what would I put in the head section and what would I put in the body section?

As it seems everything except the contents of <body> will be removed when you paste a complete HTML-source.
I've been working on this for a couple so getting to this point should make me very happy. However, I cannot figure out my infowindow output is adding "\n" to every new line. No idea how it's getting there. The geolocation is also being appended to the search result infowindow. I'd like to remove that as well.

The problem is in the data in your FusionTable (the line feeds are getting translated into "\n"). I fixed the entry for "Gorman" in my example (by removing the extraneous line feeds).
This line of my code is appending the geolocation to the search result infowindow:
infowindow.setContent(content+marker.getPosition().toUrlValue(6));
I have created a fusion table and layer that allows me to use check boxes to hide or display certain markers on the map. I would like to add a search feature that works like the pan and zoom feature. In addition, once the map zooms to the location I would like to have a radius option that identifies other locations within a certain area.
I have modified the sample code found on the IN Query (https://developers.google.com/fusiontables/docs/samples/in) and can get the checkboxes to work, but when I try to include the pan and zoom code (https://developers.google.com/fusiontables/docs/samples/search_and_zoom), I can't seem to get the search feature to work.
I have one fusion table with approximately 4000 records. I am a novice at coding so I am sure it is something in my syntax. I would also assume what I want to do is possible?
Any help would be appreciated.
Here is the code. As indicated I want to insert a search that utilizes pan and zoom feature. I ended up removing it from the code below because I was unsure how to insert or format it.
