Javascript with ASP classic loop not repeating - javascript

I have a slight issue using the following javascript within an ASP loop
<script type="text/javascript">
var geocoder, location1, location2, gDir;
function initialize() {
geocoder = new GClientGeocoder();
gDir = new GDirections();
GEvent.addListener(gDir, "load", function() {
var drivingDistanceMiles = gDir.getDistance().meters / 1609.344;
var drivingDistanceKilometers = gDir.getDistance().meters / 1000;
var drivingTime = gDir.getDuration().html
document.getElementById("<%=brokeridnum%>").innerHTML = '<strong>Address 1: </strong>' + location1.address + ' <br /><strong>Address 2: </strong>' + location2.address + '<br /><strong>Driving Distance: </strong>' + drivingDistanceMiles.toFixed(2) + ' miles taking ' + drivingTime;
});
}
</script>
<script type="text/javascript">
function showLocation(startpc, endpc) {
geocoder.getLocations(startpc, function (response) {
if (!response || response.Status.code != 200)
{
alert("Sorry, we were unable to geocode the first address");
}
else
{
location1 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address};
geocoder.getLocations(endpc, function (response) {
if (!response || response.Status.code != 200)
{
alert("Sorry, we were unable to geocode the second address");
}
else
{
location2 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address};
gDir.load('from: ' + location1.address + ' to: ' + location2.address);
}
});
}
});
}
</script>
when the loop runs the javascript only displays inside the element once.
the <%=brokeridnum%> inserts a number into the JS and this is working correctly looking at the source from chrome.
the element with the id of brokeridnum is also working.
<script type="text/javascript">
initialize();
showLocation("postcode1","<%=destpc%>");
</script>
<p id="<%=rsbkr("broker_id")%>"></p>
that is how the functions are called
Any help would be greatly appreciated!

Without seeing the entire script I can only guess...
Maybe instead of looping the entire script, try
only looping the function call with a parameter like this:
<% Do . . . %>
<script type="text/javascript">
initialize(<%= brokeridnum %>);
</script>
<% LOOP . . . %>
The function now outside the loop waits for the brokerid parameter...
function initialize(brokerid){
.....
.....
document.getElementById(brokerid).innerHTML = '......
}
Sorry about abbreviating the code a bit, but I hope I helped.

Looping through Google Place API Place Details

I'm working through the Google Place API documentation and I'm trying to get a script that pulls PlaceIDs from a webpage, and replace them with output from the Google Place API.
I managed to successfully get an output from multiple Place IDs by duplicating the code and changing the variable and function names, but now I'm trying to create a loop function so that I'm not duplicating code. Below is what I have, but I'm getting an error. By looking at the console, it seems to work up till the Callback function where it beaks down.
"Uncaught TypeError: Cannot set property 'innerHTML' of null
at callback (places.html:29)"
I've tried a few things, but no luck so far. Any suggestions would be appreciated. Thanks,
<body>
<div id="MY0">ChIJaZ6Hg4iAhYARxTsHnDFJ9zE</div>
<div id="MY1">ChIJT9e323V644kRR6TiEnwcOlA</div>
<script>
var request = [];
var service = [];
var div = [];
for (i = 0; i < 2; i++) {
request[i] = {
placeId: document.getElementById("MY" + i).innerHTML,
fields: ['name', 'rating', 'formatted_phone_number', 'geometry', 'reviews', 'photos'],
};
service[i] = new google.maps.places.PlacesService(document.createElement('div'));
service[i].getDetails(request[i], callback);
function callback(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
div[i] = document.getElementById("MY" + i);
div[i].innerHTML = "<b>" + place.name + "</b><br>" + place.rating + "<br>" + place.reviews[1].author_name + "<br>" + place.reviews[1].rating + "<br>" + place.reviews[1].text + "<br><img src='" + place.photos[0].getUrl({'maxWidth': 250, 'maxHeight': 250}) + "'>";
}
}
}
</script>
</body>
Move the callback outside of the for loop and forget about the array named div (unless you need this...if so I will rewrite). The for loop is executing before the getDetails() call returns any result, because this call is asynchronous - since you don't have much control over the Google Places callback, I would save the IDs in an array and then use them in callback, like this:
function gp_callback(place, status) {
var el = document.getElementById(window.id_set[0]); // first in first out - the for loop should populate the IDs in correct order
if (status == google.maps.places.PlacesServiceStatus.OK) {
el.innerHTML = "<b>" + place.name + "</b><br>" + place.rating + "<br>" + place.reviews[1].author_name + "<br>" + place.reviews[1].rating + "<br>" + place.reviews[1].text + "<br><img src='" + place.photos[0].getUrl({'maxWidth': 250, 'maxHeight': 250}) + "'>";
}
if (window.id_set.length > 1) {
window.id_set.splice(0, 1); // remove first element from array because has been used - now the next element is at index 0 for the next async callback
}
}
var request = [];
var service = [];
var id_set = [];
for (i = 0; i < 2; i++) {
request[i] = {
placeId: document.getElementById("MY" + i).innerHTML,
fields: ['name', 'rating', 'formatted_phone_number', 'geometry', 'reviews', 'photos'],
};
id_set.push("MY" + i); // this ensures array is populated (in proper order, b/c it tracks the execution of the for loop) for use in callback before callback is called (since getDetails() is async)
service[i] = new google.maps.places.PlacesService(document.createElement('div'));
service[i].getDetails(request[i], function(place, status) {
gp_callback(place, status);
});
}
UPDATE: More scalable and elegant answer after I had a little more time to think about it.

Make Google maps callback wait for rest of functions to finish

I am having difficulty with the way google calls its maps api. I have the following calling initMap
<script defer
src="https://maps.googleapis.com/maps/api/js?key=API_KEY_REMOVED&callback=initMap">
</script>
but inside initMap, the following condition if(getPosition() !== false) { never evaluates to true because init map is done before getPosition() has set its object values.
function initMap() {
// set new map, assign default properties
map = new google.maps.Map(document.getElementById('map'), {
center: { lat, lng }, zoom: 14
});
// check if the requested data is usable (lat, lng === numbers) before trying to use it
if(getPosition() !== false) {
map.setCenter( getPosition() ); // set latest position as the map center
addMarker();
console.log("InitMap ran here");
}
}
How can I make it so initMap waits until getPosition() has had a chance to wait for other functions to do their thing? Here is my complete script so it makes more sense.
<script>
console.log(formatTime(Date()));
// https://developers.google.com/maps/documentation/javascript/geolocation
var map; var marker;
var lat = 65.025984; var lng = 25.470794; // default map location in case no position response is available
var res_data; var res_longitude; var res_latitude; var res_speed; var res_time; // res = response (data from the ajax call)
var xhr = new XMLHttpRequest();
function getPosition() {
pos = {
lat: res_latitude,
lng: res_longitude,
};
return ( isNaN(pos.lat) || isNaN(pos.lng) ) ? false : pos; // return pos only if lat and lng values are numbers
}
function initMap() {
// set new map, assign default properties
map = new google.maps.Map(document.getElementById('map'), {
center: { lat, lng }, zoom: 14
});
// check if the requested data is usable (lat, lng === numbers) before trying to use it
if(getPosition() !== false) {
map.setCenter( getPosition() ); // set latest position as the map center
addMarker();
console.log("InitMap ran here");
}
}
// place marker on the map
function addMarker() {
//console.log("Add Marker ran");
//https://developers.google.com/maps/documentation/javascript/markers
if(marker){ marker.setMap(null); } // remove visibility of current marker
marker = new google.maps.Marker({
position: getPosition(),
map: map,
title: formatTime(res_time),
});
marker.setMap(map); // set the marker
}
function getData() {
xhr.addEventListener("load", reqListener);
xhr.open("GET", "http://example.com/data.txt");
xhr.send();
}
function reqListener() {
// res_data = long, lat, accuracy, speed, time
//console.log("reqListener: " + xhr.responseText);
res_data = '[' + xhr.responseText + ']';
res_data = JSON.parse(res_data);
res_latitude = res_data[0]; res_longitude = res_data[1]; res_accuracy = res_data[2]; res_speed = res_data[3]; res_time = res_data[4];
var formatted_time = formatTime(res_time);
document.getElementById('info').innerHTML = '<span class="info">Lat: ' + res_latitude + '</span><span class="info">Long: ' + res_longitude + '</span><span class="info">Accuracy: ' + res_accuracy + '</span><span class="info">Speed: ' + res_speed + '</span><span class="info">' + formatted_time + '</span>';
addMarker();
}
function formatTime(time) {
var t = new Date(time);
var hours, mins, secs;
if(t.getHours() < 10) { hours = "0" + t.getHours(); } else { hours = t.getHours(); }
if(t.getMinutes() < 10) { mins = "0" + t.getMinutes(); } else { mins = t.getMinutes(); }
if(t.getSeconds() < 10) { secs = "0" + t.getSeconds(); } else { secs = t.getSeconds(); }
var hms = hours +':'+ mins +':'+ secs;
return 'Updated: ' + hms;
}
function init() {
getData();
setInterval(getData, 5000);
}
init();
</script>
<script defer
src="https://maps.googleapis.com/maps/api/js?key=API_KEY_REMOVED&callback=initMap">
</script>
Get rid of the callback=initMap from where you load in the Maps API.
Instead make a call to initMap only from where you are then certain everything is loaded. e.g. at the end of reqListener.
function reqListener() {
res_data = '[' + xhr.responseText + ']';
res_data = JSON.parse(res_data);
res_latitude = res_data[0]; res_longitude = res_data[1]; res_accuracy = res_data[2]; res_speed = res_data[3]; res_time = res_data[4];
var formatted_time = formatTime(res_time);
document.getElementById('info').innerHTML = '<span class="info">Lat: ' + res_latitude + '</span><span class="info">Long: ' + res_longitude + '</span><span class="info">Accuracy: ' + res_accuracy + '</span><span class="info">Speed: ' + res_speed + '</span><span class="info">' + formatted_time + '</span>';
initMap();
addMarker();
}
If you're calling reqListener at repeated intervals and don't want to recreate your map, add some logic to the top of initMap like:
if (map !== null) {
return;
}

Google Map Geocoded TypeError in Callback function

I have the following 2 functions to pull in, geocode, and place markers in a google map.
I keep getting a TypeError: adds[i] is undefined, which of course is causing the rest of the map to bomb.
Here is my code:
// Place Markers on the Map
var PlaceMarkers = function (iw, adds, gc) {
var image = {url: "http://meatmysite.com/Images/star2.png", size: new google.maps.Size(24, 24)};
var aCt = adds.length;
for(var i = 0; i < aCt; ++i) {
GetLatLng(gc, adds[i].address, function(pos) {
if(pos) {
var ipop = '<h1>' + adds[i].title + '</h1>'; // <----- TypeError: adds[i] is undefined
if(!isBlank(adds[i].url)){
ipop += '' + adds[i].url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content' + i + '">' + adds[i].content + '</div>';
if(!isBlank(adds[i].mainphone)){
ipop += '<br /><strong>Phone:</strong> ' + adds[i].mainphone + '';
}
if(!isBlank(adds[i].mainemail)){
ipop += '<br /><strong>Email:</strong> ' + adds[i].mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({title: adds[i].title, position: pos, map: map, icon: image, html: ipop});
google.maps.event.addListener(mark, 'click', function(){
iw.setContent(this.html);
iw.open(map, this);
});
}
});
}
};
// Get Lat/Lng Location
var GetLatLng = function(gc, add, f) {
var ret = '';
gc.geocode({'address': add}, function(res, status) {
if (status == 'OK') {
f(res[0].geometry.location);
console.log('Found Here: ' + ret.toString());
}
});
return -1;
};
DEMO RETURNED DATA FOR adds
[
{
"address": "1 My Street Gilbert, AZ 85234",
"title": "My Title 1",
"url": "http://www.myurl.com/",
"mainphone": null,
"mainemail": null,

One option, pass the complete "address" object into the GetLatLng function, and from there into its callback (so you get function closure on it):
// Get Lat/Lng Location
var GetLatLng = function (gc, add, f) {
gc.geocode({
'address': add.address
}, function (res, status) {
if (status == 'OK') {
f(res[0].geometry.location, add);
}
});
};
Then use it like this inside the callback (you could pass just the index into the array also):
GetLatLng(gc, adds[i], function (pos, add) {
if (pos) {
var ipop = '<h1>' + add.title + '</h1>';
if (!isBlank(add.url)) {
ipop += '' + add.url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content' + i + '">' + add.content + '</div>';
if (!isBlank(add.mainphone)) {
ipop += '<br /><strong>Phone:</strong> ' + add.mainphone + '';
}
if (!isBlank(add.mainemail)) {
ipop += '<br /><strong>Email:</strong> ' + add.mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({
title: add.title,
position: pos,
map: map,
icon: image,
html: ipop
});
google.maps.event.addListener(mark, 'click', function () {
iw.setContent(this.html);
iw.open(map, this);
});
}
});

This looks like a typical binding issue. By the time your callback is called, the value of adds[i] will have changed. It is likely that the loop terminated and i has now a value of last index + 1, which is pointing to nothing. Note that it could also point to the wrong index, that would not fail but use the wrong data.
You must bind the value of adds[i] locally for each iteration or the callback will just use a reference to a global value. There a multiple ways to go about this, here is a simple one where we keep passing adds[i] along as a function argument.
Replace adds[i].address with adds[i] when calling GetLatLng and add a second parameter add to the callback:
GetLatLng(gc, adds[i], function(pos, add) {
...
});
Then modify GetLatLng to use add.address instead of just add and add add to the callback call:
// Get Lat/Lng Location
var GetLatLng = function(gc, add, f) {
var ret = '';
gc.geocode({'address': add.address}, function(res, status) {
if (status == 'OK') {
f(res[0].geometry.location, add);
console.log('Found Here: ' + ret.toString());
}
});
return -1;
};
Then in the callback function, replace all instances of adds[i] with add to use the local variable.
I didn't set up a test but it should theoretically work.
you appear to be overcomplicating things. Any reason why you can't do this?
// Place Markers on the Map
var PlaceMarkers = function (iw, adds, gc) {
var aCt = adds.length;
for(var i = 0; i < aCt; ++i) {
var obj=adds[i];
GetLatLng(gc, obj)
}
};
// Get Lat/Lng Location
var GetLatLng = function(gc, obj) {
var ret = '';
gc.geocode({'address': obj.address}, function(res, status) {
if (status == 'OK') {
var pos=res[0].geometry.location;
var ipop = '<h1>' + obj.title + '</h1>'; // <----- TypeError: adds[i] is undefined
if(!isBlank(obj.url)){
ipop += '' + obj.url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content">' + obj.content + '</div>';
if(!isBlank(obj.mainphone)){
ipop += '<br /><strong>Phone:</strong> ' + obj.mainphone + '';
}
if(!isBlank(obj.mainemail)){
ipop += '<br /><strong>Email:</strong> ' + obj.mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({title: obj.title, position: pos, map: map, html: ipop});
google.maps.event.addListener(mark, 'click', function(){
iw.setContent(this.html);
iw.open(map, this);
});
} else {
console.log("geocoder problem!")
}
});
};
for(var i = 0; i < aCt - 1; ++i). You need to add "-1" in you for-loop. The array starts at index 0 and not 1. You also need to be careful with using functions in a for loop. Within javascript a for-loop does not have a scope from itself. Only functions create new scopes.

how to append to div id

i know it is easy and silly question but how can i show the lat and lng append into div id instead of giving me on alert.Can i do something like that !!
document.getElementById("here").innerHTML = ("lat: +lat+"lng: " + lng)
<!DOCTYPE>
<html>
<meta name="viewport" content="width=device-width,
initial-scale=1, maximum-scale=1,user-scalable=no">
<head>
<script>
function geolocation(){
<!--checks if geolocation is available -->
var options = { enableHighAccuracy: true};
watchId = navigator.geolocation.watchPosition(onSuccess, onError, options);
<!-- function run if gets the geolocation back -->
function onSuccess(position){
var lat = position.coords.latitude;
var lng = position.coords.longitude;
alert("lat: " + lat + "lng: " + lng);
}
<!-- this function run if there is any error in geolocation -->
function onError(error){
alert("message: " + error.message);
}
}
geolocation();
</script>
</head>
<body>
<div id="here"></div>
</body>
You may try something like this: Edit: Updated HTML
<div id="location"></div>
<script>
$( document ).ready(function() {
geolocation();
}
function geolocation(){
<!--checks if geolocation is available -->
var options = { enableHighAccuracy: true};
watchId = navigator.geolocation.watchPosition(onSuccess, onError, options);
<!-- function run if gets the geolocation back -->
function onSuccess(position){
var lat = position.coords.latitude;
var lng = position.coords.longitude;
//alert("lat: " + lat + "lng: " + lng);
document.getElementById("location").innerHTML = "lat: " + lat + "lng: " + lng;
}
<!-- this function run if there is any error in geolocation -->
function onError(error){
alert("message: " + error.message);
}
}
</script>
Ok So, I think what you want is this:
div = document.getElementById('here');
div.appendChild(watchId);
Thats how you append to your particular div.
Yes, it's possible, with the property innerHTML you wrote you should solve your problem.
Yes, you definetely can. However, the string you provided is not quoted correctly. Don' t you get an exception in console?
document.getElementById("here").innerHTML = "lat: " + lat + "lng: " + lng;
Using jQuery you can simply do this:
$("#here").text("lat: " + lat + " lng: " + lng");
Or if you want to keep the content of here and append the information at the end:
$("#here").append("lat: " + lat + " lng: " + lng");

Google Maps Reloads again and the Markers disappear when i click a button in Asp.net web application

There's a small issue that i'm facing.
Part 1:
A little insight on what i'm trying to do.
Window.onload [in javascript] calls a function which displays the googlemaps nothing else.
Then on click of a button the latitude & longitude are read from the MySQL database, this code is written in C# code behind.
And from C# i call a javascript function with those latitude & longitude as parameters.
Now the javascript function Should place a marker on the received parameters, instead it reloads the googlemap and i don't see any Marker!
Part 2: I want to call a javascript again and again from a while loop to send the latest latitude and longitude as long as there is data in the MySQL table.
//The While Loop reads a row, and calls the javascript function !But for some reason the Javascript function gets called only once.
while(read.Read())
{
id= read["ID"].ToString();
lat = read["latitude"].ToString();
longitude = read["longitude"].ToString();
freq=read["frequency"].ToString();
array_ID.Add(Convert.ToInt32(id));
array_lat.Add(Convert.ToDouble(lat));
array_lon.Add(Convert.ToDouble(longitude));
array_freq.Add(Convert.ToInt32(freq));
string[] myarr = { id, lat, longitude, freq };
javascriptfunction_markers(myarr);
}
public void javascriptfunction_markers(string[] myarray_data)
{
StringBuilder javascriptFunction = new StringBuilder();
javascriptFunction.Append("qasim(");
javascriptFunction.Append("'" + myarray_data[0].ToString() + "',");
javascriptFunction.Append("'" + myarray_data[1].ToString() + "',");
javascriptFunction.Append("'" + myarray_data[2].ToString()+ "',");
javascriptFunction.Append("'" + myarray_data[3].ToString()+ "');");
Page.ClientScript.RegisterStartupScript(Page.GetType(), "OnLoadCall", javascriptFunction.ToString(), true);
}
the string built here looks like on a sample data :
qasim('1','33.2358','72.4560',5);
the javascript function 'qasim' in .aspx is :
function qasim(id,lat,lon,freq)
{
var ltlngx = [];
var x = id.toString();
var x1 = lat.toString();
var x2 = lon.toString();
var x3 = freq.toString();
alert("Function ID : " + x +" Lat: "+ x1 + " Lon: " + x2 +"Freq: "+ x3);
count = count + 1;
alert("Called times " + count.toString());
var xx = parseFloat(lat);
var yy = parseFloat(lon);
ltlngx.push(new google.maps.LatLng(xx, yy));
alert("Lat,lng is " + ltlngx[0]);
map.setCenter(ltlngx[0]);
marker = new google.maps.Marker({
map: map,
animation: google.maps.Animation.DROP,
position: ltlngx[0],
icon: 'images/map-pin.png'
});
var i=0;
(function (i, marker) {
var xx = marker.position.toString();
google.maps.event.addListener(marker, 'click', function () {
if (!infowindow) {
infowindow = new google.maps.InfoWindow();
}
infowindow.setContent('Location info:<br/><br/>Lat & Lng:' + xx + "<br/>" + " ID : "+x+" Freq: "+x3);
infowindow.open(map, marker);
});
})(i, marker);
}
