I am a total javascript/leaflet/ag-grid newbie, so please bear with me.
I am creating a website that allows users to query (add/remove) spatial points on a leaflet map based on selecting rows from ag-grid. I have no understanding/experience with React or Angular, so I am using vanilla javascript. Leaflet is used to display the data spatially.
I have spatial data that has GPS coordinates that are parent records. Each parent they have multiple children.
Spatial data
The spatial data is an external file I read into my HTML file. It looks like this:
var spatial_data = {
"type": "FeatureCollection",
"features": [
{ "type": "Feature",
"properties": { "Name": "Boulder 1", "SpatialID": "Lower Blair_0" },
"geometry": { "type": "Point", "coordinates": [ -105.39079766, 41.19044516, 2510.159912109375 ] } },
{ "type": "Feature",
"properties": { "Name": "Boulder 2", "SpatialID": "Upper Blair_1" },
"geometry": { "type": "Point", "coordinates": [ -105.39058423, 41.19655902, 2534.4599609375 ] } }
]};
Children records
There are children records for each parent spatial ID. The data is within the .js code.
The functionality I am hoping for is someone could filter the ag-grid for a route called 'Slam Dunk' and that would provide the "SpatialID":"Lower Blair_0". If they filter for 'Test two' it provides the same SpatialID. This would be available to play around within the HTML file.
myownscript.js
var rowData = [{"Route Name":"Slam Dunk","SpatialID":"Lower Blair_0"},
{"Route Name":"Test two","SpatialID":"Lower Blair_0"},
{"Route Name":"Test three","SpatialID":"Upper Blair_1"}];
var columnDefs= [
{field: 'Route Name', minWidth:10, sortable:true, filter:true},
{field: 'Sub-Area', minWidth:5, sortable:true, filter:true},
];
const gridOptions = {
columnDefs: columnDefs,
rowData: rowData,
defaultColDef:{
flex:1,
minWidth:100
},
rowSelection: 'multiple',
pagination:true
};
function onlyUnique(value, index, self) {
return self.indexOf(value) === index;
};
function grabFilteredData(){
let rowData = [];
gridOptions.api.forEachNodeAfterFilter(node => {
rowData.push(node.data.SpatialID);
});
var uniqueID = rowData.filter(onlyUnique);
return uniqueID;
}
document.addEventListener('DOMContentLoaded', () => {
const gridDiv = document.querySelector('#myGrid');
new agGrid.Grid(gridDiv, gridOptions);
});
I can easily send 'test' to the console. That provides me with the ability to check that my onSelectionChanged() is working; however, I really need to pass the output from onSelectionChanged() as an array. I need to pass that and use that in an embedded script within my HTML. This is so I can filter the data in my leaflet layers and features.

I have tried extensive searching. For some reason, the majority of use cases for gridOptions.api.getSelectedRows() or forEachNodeAfterFilter end with an example of using console.log(). I need to actually pass that information along instead of just outputting to the console. I am not sure if this is a misunderstanding on my part for how JS works, or if it is expected behavior from ag-grid, but it doesn't seem possible.
This doesn't seem to work as the console.log() in the .js file doesn't work, and in the script in the HTML it can not find test.
I am primarily a statistician/python programmer, so this a new foray for me. It is likely I am missing a bigger picture thing and if so, I would appreciate alternatives to my current approach.
So once onSelectionChanged is called with the filtered rows - what script do you need to pass it to?
I assume you want to link the table with the leaflet map. If so, you need to
obtain a reference to the map object (see Leaflet docs)
create a GeoJSON layer based on the filtered Geometries and add it to the map.
If the filtering in the table and thus the leaflet layer data update happens multiple times, you need to remove the existing layer and add a new one, as far as I know. Check this post.

I create this with leaflet with 2 geojson collection.
My issue is I want blue to be above orange.
And is it possible to don't see the orange when blue is above ? and how to do it ?
This is my code (I have the same code for both geojson)
var fc2 = {
"type": "FeatureCollection",
"features": [unionA2]
}
L.geoJson(fc2, { // initialize layer with data
style: function (feature) {
return {
color: "#ea6621"
};
}
}).addTo(map);
I am using javascript to create Google-sheets-document with user data. The document is saved on the user's Drive.
I can't figure out how to make a graph from the data i have inserted. I am using vanilla javascript with the Google sheets API.
It would probably look something like this:
function createGraph() {
gapi.client.sheets.graph
.create({
properties: {
type(?): 'Pie'
spreadsheetid: //some id
range: 'A1:A10'
},
})
}
EDIT: To specify, i want to insert the graph to the sheets-document that i have created, not to the website.
If you want to add the chart to your spreadsheet, you can use Sheets API's AddChartRequest, as part of the spreadsheets.batchUpdate method.
Code snippet:
On broad terms, your request would look like this (check the reference below in order to build the request body in detail):
const payload = {
"requests": [
{
"addChart": {
"chart": {
"spec": { // Chart type, range source, etc.
"pieChart": { // Pie chart specification
// object (PieChartSpec)
}
// rest of ChartSpec properties
},
"position": { // Where the chart will be located
// object (EmbeddedObjectPosition)
}
}
}
}
]
}
const params = {
spreadsheetId = "YOUR-SPREADSHEET-ID",
body = payload
}
gapi.client.sheets.spreadsheets.batchUpdate(params);
Render chart in browsers and mobile devices:
In case you just wanted to render the chart in a browser, but not add it to your spreadsheet, you would use Google Charts (see Visualization: Pie Chart, for example).
Reference:
Sheets API > Charts
EmbeddedChart
ChartSpec
EmbeddedObjectPosition
PieChartSpec

I have the following search results coming as the json data. For each search result there is lat and lon. So, for each search result when I click on view map, a modal will pop up and shows the marker on the google map.. but using the following code i am not getting the same..
My json data is
{"status": true, "data": [{"pid": 1, "bussinessName": "ld", "lat": 9.5273308, "lon": 76.8228674, "contactName": "bin"}, {"pid": 2, "bussinessName": "lod", "lat": 9.523308, "lon": 76.8228674, "contactName": "son"},{"pid": 3, "bussinessName": "rd", "lat": 9.5273308, "lon": 76.822867, "contactName": "in"}]}
My vue js code is
<script>
searchContent = new Vue({
el: "#searchContent",

vector: {}
}
});
categories = new Vue({
el: '#categories',
data: {
articles: [],
services: [],

var vm = this;
$.ajax({

console.log(e);
vm.articles = e;
console.log(vm);

success: function(e) {
window.searchContent.vector = e.data;
console.log(e);
var options = {
zoom: 8,

mapTypeControl: false
};
// Init map
var map = new google.maps.Map(document.getElementById('mapName'), options);
//use code
var i=0;
// Init markers
var marker = new google.maps.Marker({
position: new google.maps.LatLng(e.data.lat , e.data.lon),
map: map,
title: 'Click Me ' + i,
});
// Process multiple info windows
(function(marker, i) {
// add click event
google.maps.event.addListener(marker, 'click', function() {

content: e.data.lat
});
infowindow.open(map, marker);
});
})(marker, i);
}
})
}
}
})
</script>
My html code to display the same is
<div id="searchContent" >
<div v-for="row in vector" >
<h6>{{row.bussinessName}}</h6>
<div>
<a data-toggle="modal" data-target="#myModal1">View Map</a></div>

<!-- Modal content-->
<div id="mapName" style="width:667px; height: 370px" />
<!-- Replace the value of the key parameter with your own API key. -->
</div>
</div>
</div>
So, when I click on the view map I need to display the marker corresponding to the search result. can anyone please help me to solve the problem?
Warning: this isn't a solution - following code only demostrates how easy is to use the ready-made web components. I just think, that this information has it's value and is related to this issue, because it can greatly simplify your code / solution / life :)
Look at this example. It's using extraneous, ready-made Polymer based custom web component from webcomponents.org. As you can see, these components fully interoperates with Vue. You can not only use them, you also have full control about their properties. And best of all, you can listen to their custom events, just like in other Vue components...
So, this is maybe the easiest way to achieve what you need. Just wrap my-map with modal and set the properties to the correct values... And of course, take a look to provided link for documentation for this google-map component.
Vue.component('my-map', {
template: '#my-map',
props: ['lat', 'long'],
data () {
return {
latitude: '',
longitude: ''
}
},
methods: {
setCoords (e) {
if (e.type === 'latitude-changed')
this.latitude = e.detail.value
if (e.type === 'longitude-changed')
this.longitude = e.detail.value
}
}
})
new Vue({
el: '#app'
})
google-map {
height: 186px;
}
<base href="https://raw-dot-custom-elements.appspot.com/GoogleWebComponents/google-map/v2.0.2/google-map/">
<link rel="import" href="google-map.html">
<div id="app">
<my-map lat="37.78" long="-122.4"></my-map>
</div>
<template id="my-map">
<div>
Marker coords: lat {{ latitude }} / long {{ longitude }}
<google-map fit-to-marker api-key="AIzaSyD3E1D9b-Z7ekrT3tbhl_dy8DCXuIuDDRc">
<google-map-marker
:latitude="lat"
:longitude="long"
draggable="true"
slot="markers"
title="Your location"
#latitude-changed="setCoords"
#longitude-changed="setCoords"
>
</google-map-marker>
</google-map>
</div>
</template>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.3/vue.min.js"></script>
Honestly ... I think this combination of Vue, and Polymer based custom web components is pretty awesome. Now one can achieve unbelievable results with beautiful, declarative syntax. Did you noticed, that in this example is no additional javascript? Yes, modern browsers works with these custom components with no additional overhead. And for older browsers there is a polyfill...
I'm looking to embed tweets from selected areas in a mapbox map. Is it possible, can rich media appear in a mapbox popup? So far I've managed to get a map to display a link to a selected tweet but not the tweet itself.
I've posted part of the geojson that i'm using to show markers and popups. I placed the javascript for the tweet just after the geojson. Any help would be greatly appreciated, thanks.

The development team of Twitter themselves wrote a complete article about embedded tweets. I really recommend you to check it out, since it propose two ways that might be pretty interesting in your case:
Convert Tweet URLs using oEmbed
Render a Tweet with JavaScript
oEmbed:
Basically you will just need to add a reference to the oEmbed API in your code, and you will be able to display embedded tweets with a simple link, like so : https://publish.twitter.com/oembed?url=https://twitter.com/Interior/status/463440424141459456 .
Javascript:
Twitter provides developers a Javascript widget which contains a lot of pretty usefull function to decide when and where a tweet should be displayed on your website. This could be a pretty good solution in your case, and I really recommand you to read the article about it from the Twitter team.
I am new to SAPUI5/OPENUI5.
I am trying out a sample program to consume json data from a domain and display it in my openui5 table. I have tried two methods to get the data and bind it to table control.But I am not able to generate the table with the json data.
Please let me know my mistake in the code.
And also please refer me some links to understand the concept in a better way.
Thanks in advance.
Please find the two approaches below :
JSON Data :
[
{
"name": "Rajesh"
},
{
"name": "Kunal Jauhari"
},
{
"name": "Ashish Singh"
},
{
"name": "Ansuman Parhi"
},
{
"name": "Arup Kumar"
},
{
"name": "Deepak Malviya"
},
{
"name": "Seshu"
},
{
"name": "Ankush Datey"
},
{
"name": "Tapesh Syawaria"
},
{
"name": "Mahesh"
},
{
"name": "Vinay Joshi"
},
{
"name": "Ardhendu Karna"
},
{
"name": "Abhishek Shukla"
},
{
"name": "Kashim"
},
{
"name": "Vinayak"
}
]
Approach 1 : I am using a php file to echo the JSON data and use it in my ui5 screen.
When I access the run the php file individually, it generates the data and prints the data on screen.
Error I get is getJSON is not called.
Code :

//Define the columns and the control templates to be used
oTable1.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "Player Name"
}),
template : new sap.ui.commons.TextView().bindProperty(
"text", "name"),

}));
oTable1.setModel(oModel);
oTable1.bindRows("/oModel");
oTable1.placeAt('table_cont');
},
error : function(jqXHR,textStatus,errorThrown) {
alert("Oh no, an error occurred");
alert(jqXHR);
alert(textStatus);
alert(errorThrown);
}
});
</script>
</head>
<body class="sapUiBody" role="application">
<div id="table_cont"></div>
</body>
</html>
Approach 2 : I am trying to access the JSON file directly on my domain and access the data.
Code is the same as above except url.
Url is used for this approach is (mydomain/players.json) where players.json contain the above json data.
Please help me in understanding the concept of JSON data handling.
Regards,
Rajan
First of all: SAPUI5 is built onto jQuery, yes. But there should be no need to use jQuery inside your SAPUI5 Application.
Use a JSONModel to load JSON-Data. Also the JSONModel can load the data from URL.
See the Documentation
this will look like:
// create a "json" Model
var oModel = new sap.ui.model.json.JSONModel();
// load data from URL
oModel.loadData('http://mydomain/teamdetails_ui5.php?t=6');
after this you can register this model in your sap.ui.core with:
sap.ui.getCore().setModel(oModel);
after this line every control can use the data from this model by simple binding-syntax.
Now lets create the table:
// create your table
var oTable1 = new sap.ui.table.Table({
title : "Players List",
visibleRowCount : 3,
selectionMode : sap.ui.table.SelectionMode.Single,
navigationMode : sap.ui.table.NavigationMode.Paginator,
// bind the core-model to this table by aggregating player-Array
rows: '{/player}'
});
beware of the part with "rows: '{/player}'". This is the only thing that has to be done to get the data from the model inside your table.
now finish the demo by adding the column and add the table to the DOM:
// define the columns and the control templates to be used
oTable1.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "Player Name"
}),
template : new sap.ui.commons.TextView({
text: '{name}'
}),
width : "10px"
}));
//place at DOM
oTable1.placeAt('content');
Thats it. If it doesn't work, here is a running DEMO.
