I have just updated my code from v2 to v3. Every thing is working but the function map.fitBounds();
Here is my sample code
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': 'your address'}, >function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var newPoint = new google.maps.LatLng(results[0].geometry.location.lat(), >results[0].geometry.location.lng());
markerBounds.extend(newPoint);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
map.fitBounds(markerBounds);
}
I have found that this code looks fine but here fitBounds() will not work. The required change is mention in the answer below.
In this case we have to write code like this
markerBounds.extend(newPoint);
map.fitBounds(markerBounds); // here in function rather in the end
This worked for me hopefully will work for you as well.

I wrote some backend code for a Parse.com mobile app a couple of years ago, and have just been asked to add a feature. However, I found that after a small tweak the code wouldn't succeed. So, I rolled back to the working copy, downloaded, then deployed that back and it wouldn't work either! I wonder if this is a change in the Parse software?
The code is failing at the save method as all the logs are fine until then. The log for the error case shows 'No message provided'. If I don't use the message attribute it just shows '{}', so I presume it's empty. I have put the promise resolution in the error case to stop the job timing out while I debug. One thing I have never understood is why I have to make two Seed objects and piggy-back off one to save correctly. If I did a.save(null,...) it wouldn't work.
Any help would be fantastic. Thanks!
PS: Apologies for the indenting below - it is correct in my file.
function flush() {
//Clear the previous records from the class.
var Seed = Parse.Object.extend("Seeds");
var _ = require("underscore");
var arr = [];
var query = new Parse.Query(Seed);
return query.find().then(function(oldSeeds) {
_.each(oldSeeds, function(oldSeed) {
arr.push(oldSeed.destroy());
});
return Parse.Promise.when(arr);
});
}
Parse.Cloud.job("fetchjson", function(request, status) {
var url = 'someurl';
flush().then(function() { Parse.Cloud.httpRequest({url: url}).then(function(httpResponse){
var Seed = Parse.Object.extend("Seeds");
var jsonobj = JSON.parse(httpResponse.text);
var _ = require("underscore");
var results = [];
// do NOT iterate arrays with `for... in loops`
_.each(jsonobj.seeds, function(s) {
var p = new Parse.Promise();
results.push(p); // Needs to be done here or when() will execute immediately with no promises.
var seed = new Seed();
var a = new Seed(s);
var image_url = a.get("image")
//Get the JSON.
Parse.Cloud.httpRequest({url: image_url}).then(function(response) {
console.log("Fetching image at URL: " + image_url);
//Create a new image object and save, passing ref through promise.
var file = new Parse.File('thumb.jpg', { base64: response.buffer.toString('base64', 0, response.buffer.length) });
return file.save();
}).then(function(thumb) {
console.log("Attaching thumb to object");
//Set image ref as object attribute.
a.set("imageFile", thumb);
console.log("Parsing views into viewsint");
//Save decimal string as int into another attribute.
a.set("viewsInt", parseInt(a.get("views")));
console.log("Parsing description into descriptionarray");
//Save string as array into another attribute.
var dar = new Array(1);
//dar[0] = a.get("description")
a.set("descriptionarray", [a.get("description")]);
}, function(error) {
console.log("Error occurred :(");
}).then(function(){
console.log("Saving object");
//Save the object and resolve the promise so we can stop.
seed.save(a,{
success: function(successData){
console.log(successData);
p.resolve(successData);
},
error: function(error){
console.log(error.message);
p.resolve(error);
}
});
});
});
// .when waits for all promises to be resolved. This is async baby!
Parse.Promise.when(results).then(function(data){
console.log("All objects saved");
status.success("Updated Succesfully");
});
}, function(error) {
//Oh noes :'(
console.error('Request failed with response code ' + httpResponse.status);
status.error("Update Failed");
});
});
});
I changed your code a bit and put some comments to explain:
// DEFINE THESE ON THE TOP. NO NEED TO REPEAT.
var _ = require("underscore");
var Seed = Parse.Object.extend("Seeds");
function flush() {
//Clear the previous records from the class.
var arr = [];
var query = new Parse.Query(Seed);
return query.find().then(function(oldSeeds) {
_.each(oldSeeds, function(oldSeed) {
arr.push(oldSeed.destroy());
});
return Parse.Promise.when(arr);
});
}
Parse.Cloud.job("fetchjson", function(request, status) {
var url = 'someurl';
flush().then(function() {
Parse.Cloud.httpRequest({url: url}).then(function(httpResponse){
var jsonobj = JSON.parse(httpResponse.text);
var results = [];
_.each(jsonobj.seeds, function(s) {
// ONE SEED OBJECT WITH INITIAL SET OF DATA FROM JSON
var seed = new Seed(s);
var image_url = seed.get("image")
// A SERIAL PROMISE FOR EACH SEED
var promise = Parse.Cloud.httpRequest({url: image_url}).then(function(response) {
console.log("Fetching image at URL: " + image_url);
//Create a new image object and save, passing ref through promise.
var file = new Parse.File('thumb.jpg', { base64: response.buffer.toString('base64', 0, response.buffer.length) });
return file.save();
}).then(function(thumb) {
// SETTING MORE PROPERTIES
//Set image ref as object attribute.
console.log("Attaching thumb to object");
seed.set("imageFile", thumb);
//Save decimal string as int into another attribute.
console.log("Parsing views into viewsint");
seed.set("viewsInt", parseInt(seed.get("views")));
//Save string as array into another attribute.
console.log("Parsing description into descriptionarray");
seed.set("descriptionarray", [seed.get("description")]);
// SAVING THE OBJECT
console.log("Saving object");
return seed.save();
});
// PUSH THIS PROMISE TO THE ARRAY TO PERFORM IN PARALLEL
results.push(promise);
});
Parse.Promise.when(results).then(function(data){
console.log("All objects saved");
status.success("Updated Succesfully");
});
}, function(error) {
console.error('Request failed with response code ' + httpResponse.status);
status.error("Update Failed");
});
});
});
Thanks knshn. I had refactored the code a lot since that version (including several of the changes you made), but I had posted the version that was identical to that which was working fine before. Your changes let me see the right error. For some reason doing the simple single object implementation didn't work for me originally, hence the nasty workaround. It works now though.
I have now found the culprit - the Seed class had an attribute called 'id'. With the old version this worked fine, but when I deployed that code now it gave an error 101: 'object not found for update'. This must be because the new Parse code is mixing that up with the internal objectId and getting confused that the id is different to what it expects. I wonder how that could still work with the rollback though. Perhaps the at version was tagged to use the older Parse code.
My fix was to use a different name for the id - 'seed_id'.
I've been scratching my head over this for a while. What am I doing wrong? Your help is much appreciated :)
I've tried many different image codes, but I think it's a promise issue I'm seeing. With the code below I only see the "Start of loop" log message.
If I move the results push outside the promise structure to underneath then I see the Stage log messages, albeit after all the Start of loops have printed (hence why I put the push in the then function).
Parse.Cloud.job("fetchjson", function(request, status) {
var url = 'some json url';
Parse.Cloud.httpRequest({url: url}).then(function(httpResponse){
//var Image = require("parse-image");
var Seeds = Parse.Object.extend("Seeds");
var jsonobj = JSON.parse(httpResponse.text);
var results = [];
// do NOT iterate arrays with `for... in loops`
for(var i = 0; i < jsonobj.seeds.length; i++){
var seed = new Seed();
var a = new Seed(jsonobj.seeds[i]);
console.log("Start of loop");
Parse.Cloud.httpRequest({url: a.get("image") }).then(function(response) {
console.log("Stage 1");
//var file = new Parse.File('thumb.jpg', { base64: response.buffer.toString('base64', 0, response.buffer.length) });
//return file.save();
return "hi"
}).then(function(thumb) {
console.log("Stage 2");
//a.set("imageFile", thumb);
//a.set("viewsInt", parseInt(a.get("views")));
}, function(error) {
console.log("Error occurred :(");
}).then(function(){
results.push(seed.save(a)); // add to aggregate
});
}
// .when waits for all promises
Parse.Promise.when(results).then(function(data){
status.success("All saved");
});
}, function(error) {
console.error('Request failed with response code ' + httpResponse.status);
status.error("Failed");
});
});
i'm displaying a google maps in codeigniter and this works all fine.
But i'm using the same code in an ajax call, but than it outputs an empty map_canvas, so i don't see anything..
public function googlemapsAjax()
{
echo "
<script type='text/javascript'>
$.getScript('/assets/js/admin.js');
</script>
";
$this->load->library('googlemaps');
$config['center'] = '50.850340, 4.351710';
$config['zoom'] = '6';
$config['places'] = TRUE;
$config['placesAutocompleteInputID'] = 'location';
$config['placesAutocompleteBoundsMap'] = TRUE; // set results biased towards the maps viewport
$config['placesAutocompleteOnChange'] = '
var geocoder = new google.maps.Geocoder();
var address = document.getElementById("location").value;
geocoder.geocode({ "address": address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if(typeof marker != "undefined"){marker.setMap(null)};
$("#location").parent().removeClass("has-error");
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
$("#latitude").val(latitude);
$("#longitude").val(longitude);
marker = new google.maps.Marker({
map:map,
draggable:true,
animation: google.maps.Animation.DROP,
position: new google.maps.LatLng(latitude, longitude)
});
map.setCenter(new google.maps.LatLng(latitude, longitude), 16);
map.setZoom(16);
google.maps.event.addListener(marker, "dragend", function (event) {
latitude = this.getPosition().lat();
longitude = this.getPosition().lng();
$("#latitude").val(latitude);
$("#longitude").val(longitude);
});
} else {
alert("Request failed.")
$("#location").parent().addClass("has-error");
}
});
';
$this->googlemaps->initialize($config);
$data['map'] = $this->googlemaps->create_map();
$this->load->view('admin/ajax/view_googlemaps_ajax', $data);
}
And in my view i have
echo $map['js'];
and
echo $map['html'];
Anyone knows why i have no output in map_canvas?
While it works perfectly if i don't do it over ajax..
#jen_vdp - Thanks for using my library. I've taken a look and believe the issue is to do with how the map is called/initialized.
If you revert back to the non-ajax version and view the page source, you will see that the map is initialized through the following code:
google.maps.event.addDomListener(window, "load", initialize_map);
Obviously, if you load the map via AJAX, the window is already loaded, and therefore, I don't 'think' this will get executed.
My suggestion would be to manually call the JS function initialize_map() on the success callback of your AJAX request.
That's the only thing I can think that it might be at this time. Do let me know if you continue to experience issues and I'll investigate further.
Thanks,
Steve
It's my first post here : )
I'm learning CasperJS and I have to write script who search all img's on site and check urls.
I found this tutorial from vgaltes.com
var imagesArray = [];
function getImages() {
var scripts = document.querySelectorAll('img[src]');
return Array.prototype.map.call(scripts, function (e) {
return e.getAttribute('src');
});
};
casper.start('http://fooo.fooo', function () {
imagesArray = this.evaluate(getImages);
var self = this;
imagesArray.forEach(function (item) {
if (self.resourceExists(item)) {
self.echo(item + ' loaded');
} else {
var message = item + ' not loaded';
self.echo(message, 'ERROR');
}
});
});
but when I run this code on CasperJS (with valid url) do not work. Nothing happens.
Casper Version is 1.1
Looks like you did not run the function, try adding the below code in the end
casper.run(function() {this.test.renderResults(true);});
I'm the owner of vgaltes.com. As Pbk1303 said, you have to call to run function. If you read the tutorial, is the last source code posted.
casper.run(function(){
this.echo('finished');
this.test.done(1);
this.test.renderResults(true);
});
Regards,
I'm a little new to JSON so trying to understand what is the best way to do this. I have two variables: postcode and energyrating that I want to put into JSON and then parse to a for loop.
I can get it to work with one variable but when I have two it doesn't work.
Here is my JSON:
header('Content-type: application/json');
$postcodeArray = array('postcodes' => array("E6 2JG","SE1 2AQ","DA1 1DZ"), 'energyrating' => array("A","B","C","D","E","F","G"));
die(json_encode($postcodeArray));
Here is my jQuery:
function addNew(postcodes) {
if(postcodes.length > 0) {
for(var i = 0; i < postcodes.length; i++) {
var address = postcodes[i];
var rating = energyrating[i];
geocoder.geocode( { 'address': address }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var image = '../img/markers/' + rating + '.png';
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
icon: image
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
} else {
alert("Sorry, no data was found.");
}
}
How do I get this to work with both variables?
What does not work exactly ?
Reading your code, I would say there is an error into your code. The energyrating argument is missing into your addNew function:
function addNew(postcodes, energyrating) {
Assuming that you call your function like this:
addNew(jsonData.postcodes, jsonData.energyrating);
Use json variables to store the data like that :
$postcodeArray = '{"postcodes":{"0":E6, "1":"2JG", "3":"SE1 2AQ","4":"DA1 1DZ"}, "energyrating":{"0":"A","1":"B","2":"C","3":"D","4":"E","5":"F","6":"G"}}';
In the place of
$postcodeArray = JSON.parse('postcodes' => array("E6 2JG","SE1 2AQ","DA1 1DZ"), 'energyrating' => array("A","B","C","D","E","F","G"));
And you can access the values.
Or try json_decode(postcodes) in the function addNew in first line.
