I am not a developer but have used Google search and trial and error test scenarios with Zapier for the last few days and have given up on figuring this out myself. I need help!
I'm using the Run JavaScript code step in Zapier and provided the following details to Input Data.
It says: What input data should we provide to your code (as strings) via an object set to a variable named inputData?
I'm using "street" with a street address example "1402 Spring Garden Rd"
What is the code to use that regardless of the street address provided all the numbers and first space are removed so that the results is "Spring Garden Rd"
Thank you in advance!
var street = inputData;
var streetNoNumbers = inputData.replace(/[0-9]/g, '');
return streetNoNumbers
The error message I'm getting is
TypeError: inputData.replace is not a function
I've learned that strings are immutable and a new string can be made from manipulating another string but doing this in zapier seems to require a function and creating another var with the calculation generates a ... is not a function.
I've tried to write a function but can't get the output or return to show the proper results either.
I can do the following successfully,
var street = inputData
return street
1402 Spring Garden Road
I want to include the code that manipulates street to produce the following:
Spring Garden Road
David here, from the Zapier Platform team. Great question!
The key understanding you're missing is that inputData is a js object with a street property. Before your code is run, we set it up like so:
const inputData = {street: '1402 Spring Garden Rd'}
Since inputData is an object, it doesn't have a replace method (the error you're seeing). Instead, perform your operation on .street and return that.
Try the following:
// need to return an object, not just a string
return {streetNoNumbers: inputData.replace(/[0-9]/g, '')}

I have defined Latitude and Longitude in my database. Both are Float data type. I want to display the geo information on a map. My problem is when I use #Model (I am using Asp.net MVC and Razor syntax) to pass these information to varables. The code is
var latitude = #Model.Latitude;
var longitude = #Model.Longitude;
It showed me a curly red line behind each line. And when I hovered mouse there, it displayed like
Double?Dinner.Latitude
Double?Dinner.Longitude
I dont have any idea about it. Then I tried to cast the datatype like
var latitude = (double)(#Model.Latitude);
var latitude = (double)(#Model.Longitude);
The red curly line did dispear but it showed me
"Undefined Double"
Who knows why?
Thanks
decimal latitude = Convert.ToDecimal(Model.Latitude);
decimal longitude= Convert.ToDecimal(Model.Longitude);
When you are on a razor scope, you do not need to use # keyworkd to access server-side values. Just try to open a razor block and set the variables, try something this:
#{
var latitude = (double)Model.Latitude;
var longitude= (double)Model.Longitude;
}
And then to show it, use the # razor keyworkd:
<p>#latitude</p>
<p>#longitude</p>
you also can format this values using ToString() method from double type:
<p>#latitude.ToString("0.000")</p>
On many sites I saw printed out my current city where I am (eg "Hello to Berlin."). How they do that? What everything is needed for that?
I guess the main part is here javascript, but what everything I need for implementing something like this to my own app? (or is there some gem for Rails?)
Also, I would like to ask for one thing yet - I am interesting in the list of states (usually in select box), where user select his state (let's say Germany), according to the state value are in another select displayed all regions in Germany and after choosing a region are displayed respective cities in the selected region.
Is possible anywhere to obtain this huge database of states/cities/regions? Would be interesting to have something similar in our app, but I don't know, where those lists get...
You need a browser which supports the geolocation api to obtain the location of the user (however, you need the user's consent (an example here) to do so (most newer browsers support that feature, including IE9+ and most mobile OS'es browsers, including Windows Phone 7.5+).
all you have to do then is use JavaScript to obtain the location:
if (window.navigator.geolocation) {
var failure, success;
success = function(position) {
console.log(position);
};
failure = function(message) {
alert('Cannot retrieve location!');
};
navigator.geolocation.getCurrentPosition(success, failure, {
maximumAge: Infinity,
timeout: 5000
});
}
The positionobject will hold latitude and longitude of the user's position (however this can be highly inaccurate in less densely populated areas on desktop browsers, as they do not have a GPS device built in). To explain further: Here in Leipzig in get an accuracy of about 300 meters on a desktop computer - i get an accuracy of about 30 meters with my cell phone's GPS device.
You can then go on and use the coordinates with the Google Maps API (see here for reverse geocoding) to lookup the location of the user. There are a few gems for Rails, if you want. I never felt the need to use them, but some people seem to like them.
As for a list of countries/cities, we used the data obtainable from Geonames once in a project, but we needed to convert it for our needs first.
Internet Service Providers buy up big chunks of IP addresses, so what you're most likely seeing is a backtrace your IP to a known ISP. They have a database with ISP's and their location in the world, so they can try to see where you're from. You could try to use a site like http://www.ipaddresslocation.org/ to do your work. If you look around, there is bound to be a site that lets you enter an IP and get a location, so you just send a POST request to that site with your visitor's IP and scrape the location from the response.
Alternatively you could try to look for an ISP database that has location and what chunks of the IP range they have been allocated. You could probably find one for money, but a free one might be harder to find.
Alternatively, check out this free database http://www.maxmind.com/app/geolite
I've found getCurrentPosition() to often be inaccurate since it doesn't spend a lot of time waiting on the GPS to acquire a good accuracy. I wrote a small piece of JavaScript that mimics getCurrentPosition() but actually uses watch position and monitors the results coming back until they are better accuracy.
Here's how it looks:
navigator.geolocation.getAccurateCurrentPosition(onSuccess, onError, {desiredAccuracy:20, maxWait:15000});
Code is here - https://github.com/gwilson/getAccurateCurrentPosition
Correc syntax would be :
navigator.geolocation.getCurrentPosition(successCallBack, failureCallBack);
Use :
navigator.geolocation.getCurrentPosition(
function(position){
var latitude = position.coords.latitude;
var longitude = position.coords.longitude;
console.log("Latitude : "+latitude+" Longitude : "+longitude);
},
function(){
alert("Geo Location not supported");
}
);
If you prefer to use ES6 and promises here is another version
function getPositionPromised() {
function successCb(cb) {
return position => cb(position);
}
function errorCb(cb) {
return () => cb('Could not retrieve geolocation');
}
return new Promise((resolve, reject) => {
if (window.navigator.geolocation) {
navigator.geolocation.getCurrentPosition(successCb(resolve), errorCb(reject));
} else {
return reject('No geolocation support');
}
})
}
And you can use it like this:
getPositionPromised()
.then(position => {/*do something with position*/})
.catch(() => {/*something went wrong*/})
Here is an another api to find out the location in PHP,

I have been using geoip.maxmind.com for quite a while and it works 100%. It can be accessed via HTTP requests.
How can I get/set the bonding box of a Google map? I know how to create map using center and zoom, but I need a way to save the view of map based on its boxing and the recreate the same view later using the map bonds (NE and SW of map)
Any idea how I can do this?
I am using MVC 3.
You want to use the map.getBounds() function which returns a LatLngBounds object. From this you can then use getNorthEast() and getSouthWest() to get the coordinates you want.
var bounds = map.getBounds();
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
If you need those LatLng objects to then be strings (for inserting to your DB or writing to a cookie or whatever), just use the toString() function on them.
strNE = NE.toString();
strSW = SW.toString();
So let's assume you write these to a cookie or use Ajax to write these to your DB. Once you get them out of the cookie/DB later, you can then just use those for setting the center of the map:
bounds = new google.maps.LatLngBounds(SW, NE);
map.fitBounds(bounds); // or maybe try panToBounds()
All these functions are documented here: https://developers.google.com/maps/documentation/javascript/reference
Using jQuery Flot, I can pass a null value to the plotting mechanism so it just won't draw anything on the plot. See how the missing records are suppressed:
I'm looking to move to d3js, so that I can have deeper low level control of the graphics using SVG. However, I have yet to find out how to do that same process of suppressing missing records. The image below is an attempt to do this, using a value of 0 instead of null (where the d3 package breaks down). Here is some code to give you an idea of how I produced the graph below:
var line = d3.svg.line()
.x(function(d) {
var date = new Date(d[0]);
return x(date);
})
.y(function(d) {
var height = d[1];
if (no_record_exists) {
return y(0);
}
return y(height) + 0.5;
});
I looked up the SVG path element at the Mozilla Developer Network, and I found out that there is a MoveTo command, M x y, that only moves the "pen" to some point without drawing anything. Has this been implemented in the d3js package, so that I won't have to create several path elements every time I encounter a missing record?
The defined function of d3.svg.line() is the way to do this
Let's say we want to include a break in the chart if y is null:
line.defined(function(d) { return d.y!=null; })
Use line.defined or area.defined, and see the Area with Missing Data example.
