Loop JS object data in multiple arrays - javascript

I have some data in a Google Spreadsheet, which I'm pulling with Tabletop.js. I'm able to display my data as well in my showInfo() function. All good.
Now I try to achieve to display this data in a default Google Chart. In this case I use their map package to display my data on a map. They provided me some sample code, see here.
At the moment I'm struggling with the following function, whole code in my Fiddle:
mapdata.addRows([
// PREFERRED DATA TO COLLECT:
// [data.geoloc, data.GM_NAAM, 'blue' ],
// THE HARDCODED WAY:
['Kerkbrink 2 ANLOO', 'ANLOO', 'green'],
['Grote Kerkstraat 32 WIJK EN AALBURG', 'WIJK EN AALBURG', 'blue']
]);
How do I approach? I managed to display all data with a forEach in the showInfo function, but this does not work in this array.
I'm pretty new in JS-land, so I appreciate every help on achieving this.
Thanks in advance!

please find the updated fiddle here
is this what you are looking for ?
updated js code:
/* 1: tabletop shizzle */
var publicSpreadsheetUrl = 'https://docs.google.com/spreadsheets/d/1cpSdKrQK0DfRoC9_xgmAqwVaDqw8BKMOL7drA_QFIn0/edit?usp=sharing';
function init() {
Tabletop.init( { key: publicSpreadsheetUrl,
callback: showInfo,
simpleSheet: true } )
}
function showInfo(data, tabletop) {
alert('Successfully processed!')
var chartdiv = document.querySelector(".chart_div");
console.log("data: ", data);
data.forEach( function(data) {
// card
var card = document.createElement('div');
card.classList.add("card");
//content

content.classList.add('content');
content.innerHTML = data.GM_NAAM + ' ' + data.geoloc;

Pie chart export to CSV / XLSX with amCharts.js

I can't find a way to export my data from a pie chart to CSV or XLSX. I checked this link from amCharts.js but I can manage to adapt it to my need.
Here's my code:
function getDataProviderForEventsByFlow(){
$.ajax({
url: restURI,
success: function(data) {
am4core.useTheme(am4themes_kelly);
chartEventsByFLow = am4core.create("events-by-flow", am4charts.PieChart);
chartEventsByFLow.hiddenState.properties.opacity = 0;
chartEventsByFLow.legend = new am4charts.Legend();
var marker = chartEventsByFLow.legend.markers.template.children.getIndex(0);
marker.cornerRadius(12, 12, 12, 12);
marker.strokeWidth = 2;
marker.strokeOpacity = 1;
marker.stroke = am4core.color("#ccc");
chartEventsByFLow.data = data;
var series = chartEventsByFLow.series.push(new am4charts.PieSeries());
series.dataFields.value = "number";
series.dataFields.category = "category";
series.dataFields.color = "color";
series.labels.template.disabled = true;
series.ticks.template.disabled = true;
series.slices.template.tooltipText = "";
}
});
}
And the export functions :
function exportCSVbyFlow() {
chartEventsByFLow.export.toCSV({}, function(data) {
this.download(data, this.defaults.formats.CSV.mimeType, "exportCSVvolumetryByFlow.csv");
});
}
function exportXLSXbyFlow() {
chartEventsByFLow.export.toXLSX({}, function(data) {
this.download(data, this.defaults.formats.XLSX.mimeType, "exportXLSXvolumetryByFlow.xlsx");
});
}
This is the output in console:
Cannot read property 'toCSV' of undefined
Cannot read property 'toXLSX' of undefined
Thank you !
The code you give is using v4 but the link you're trying to use as an example is using v3.
Have you seen this page? It shows a way to add a menu to a chart with different export options. It also talks about programatically exporting using code like:
chart.exporting.export("csv");

FancyTree activate function for a node on initiating

i need some help. I am trying to build a fancytree with url as source
var currentTree = $('#files_tree');
var urlBase = currentTree.attr("data-url");
currentTree.fancytree({
extensions: ["glyph", "dnd"],
glyph: {map: glyphIconClasses()},
// selectMode: 1,
source: {url: urlBase ,
data: {mode: "all"},
cache: false
},
activate: function (event, data) {
//data.node.render();
//show_edit_node_fnc(data.node.key);
//currentNodeToEdit = data.node;
id = data.node.data.id;
filesof = data.node.data.filesof;
list_files( filesof , id ) ; // Call to another JS function
},
and i make the content using php array, and send the request as json response
$arrFileTree['title'] = $project->name;
$arrFileTree['folder'] = true;
$arrFileTree['expanded'] = true;
$arrFileTree['activated'] = true;
$arrFileTree['data'] = array("filesof" => "project" , "id" => $project->id);
$arrSource = $project->sources ;
if($arrSource){
$arrChildren = array();
foreach($arrSource as $source){
$arNode['key'] = $source->id;
$arNode['title'] = $source->title;
$arNode['folder'] = true;
$arNode['data'] = array("filesof" => "source", "id" => $source->id);
$arrChildren[] = $arNode;
}
$arrFileTree['children'] = $arrChildren;
}
return array($arrFileTree);
what I need is, when i load the page for the first time, that an element be activated and the default "activate" function to be called on some value i assigned in php like ($arrFileTree['activated'] = true;)
So when i page loaded the "activate" function for a node will be called, and it will call my second function "list_files"
could anyone help me with this ?
Thanks
Wael
You could define the active state in the source data
...
$arrFileTree['active'] = true;
and trigger the activate event when the data was loaded:
$("#tree").fancytree({
source: {
...
},
init: function(event, data) {
data.tree.reactivate();
},

How to load google chart after getting response from jquery .post() function?

I am working on a UI where a user chooses both a start and end dates in order to retrieve data. Some of these data are shown in tables and I want to show a google chart related to those data displayed.
When the user finally chooses the dates, i send these two variables by using the $.post() function as follows:
<script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1.1','packages':['corechart']}]}"></script>
$('#button-send').click(function() {
var url_route = "{{URL::action('Controller#general_stats_post')}}";
var start_date=$('#start_date_i').val();
var end_date=$('#end_date_i').val();
var datos = {start_date: start_date, end_date:end_date,_token:_token};
Once the send button is clicked, i use the $.post() function which works fine:
$.post(url_route, datos, function(data,status){
if(status=='success'){
console.log('Dates sent successfully. Now the data retrieved are: '+data);
var response = jQuery.parseJSON(data);
if(response.events_types.length === 0){
console.log('events_types is empty.');
}
else{
console.log('The string for google charts got is: `'+response.events_types+'`');
/*Here goes the google chart*/
}
}else if(status=='error'){
console.log('Errors found');
}
});//end of .post() function
}); //end of onclick button-send
The events_types string is, for example:
[['Event','Total'],['Workshop',1],['Seminar',1]]
which perfectly works in google's jsfiddles.
So, what i have been trying is to put the google chart's drawChart() function inside the {} where the string events_types does exist as follows:
$.post(url_route, datos, function(data,status){
if(status=='success'){
console.log('Dates sent successfully. Now the data retrieved are: '+data);
var response = jQuery.parseJSON(data);
if(response.events_types.length === 0){
console.log('events_types is empty.');
}
else{
console.log('The string for google charts got is: `'+response.events_types+'`');
/*GOOGLE CHART*/
google.setOnLoadCallback(drawChart);
function drawChart() {
console.log('Inside the drawChart() function');
var data = google.visualization.arrayToDataTable(response.events_types);
var options = {
title: 'My test'
};
var chart = new google.visualization.PieChart(document.getElementById('eventos_charts'));
chart.draw(data, options);
}
/*END OF GOOGLE CHART PART*/
}
}else if(status=='error'){
console.log('Errors found');
}
});//end of .post() function
}); //end of onclick button-send
I have put a console.log message to let me know that the drawChart() has been run. However, I never get that message. So this means the drawChart() function is never run :/ I am stuck.
Almost working - EDIT
This is the code that is working... but only if I define the data string manually, that is to say:
else{
console.log('The data string is: `'+response.tipos_eventos+'`');
var the_string=response.tipos_eventos;
/***** start Google charts:*******/
//google.setOnLoadCallback(drawChart);
function drawChart() {
console.log('Inside the drawChart() function');
var data = google.visualization.arrayToDataTable([['Evento','Cantidad'],['Taller',1],['Seminario',1]]);//DEFINED MANUALLY
var options = {
title: 'The chart'
};
var chart = new google.visualization.PieChart(document.getElementById('events_types'));
chart.draw(data, options);
}
drawChart();//Thanks to #FABRICATOR
/**** END Google charts: Events types *********/
}
However, if i tried to get the data dynamically:
else{
console.log('The data string is: `'+response.tipos_eventos+'`');
var the_string=response.tipos_eventos;
/***** start Google charts:*******/
//google.setOnLoadCallback(drawChart);
function drawChart() {
console.log('Inside the drawChart() function');
var data = google.visualization.arrayToDataTable(the_string);//DEFINED DYNAMICALLY
var options = {
title: 'The chart'
};
var chart = new google.visualization.PieChart(document.getElementById('events_types'));
chart.draw(data, options);
}
drawChart();//Thanks to #FABRICATOR
/**** END Google charts: Events types *********/
}
I get the following error:
Uncaught Error: Not an array
Any ideas to make it work? What am I missing?
Finally I have found the easiest solution.
Given that I am using Laravel's ORM (Illuminate/Database), the gotten data comes in json format.
This works for Laravel and Slim framework.
So I pass the variables directly to the view (in Slim):
$app->render('home.php',[
'myArray'=>$myArray
]);
Then, inside the view (in this case, Twig view. It should be similar in blade), I get the array and put it in a variable inside the Javascript code:
var myArray = {{ myArray|json_encode|raw }};
Then I iterate to get each element and add it into the Google chart data array:
$.each(myArray,function(index, value){
//console.log('My array has at position ' + index + ', this value: ' + value.r1);
data.addRow([value.col1,value.col2,value.col3,value.col4]);
});
And it works now.

How to get system properties __CreatedAt, __Version in javascript backend of Azure Mobile services?

I am trying to explicitly get the system properties from my table but it is not working. I can see that the URL is returning all the data including these fields if I use https://myservice.azure-mobile.net/tables/todoitem?__systemProperties=* but on the code I cannot get it as item.__version or item.version. I have tried adding todoitemtable = WindowsAzure.MobileServiceTable.SystemProperties.All; but no success! I have also looked at http://azure.microsoft.com/en-us/documentation/articles/mobile-services-html-validate-modify-data-server-scripts/ but this is adding a new column instead of using the existing system columns.
$(function() {
var client = new WindowsAzure.MobileServiceClient('https://ib-svc-01.azure-mobile.net/', 'key');
var todoItemTable = client.getTable('todoitem');
// = WindowsAzure.MobileServiceTable.SystemProperties.All;
// Read current data and rebuild UI.
// If you plan to generate complex UIs like this, consider using a JavaScript templating library.
function refreshTodoItems() {
var query = todoItemTable.where({ complete: false });
query.read().then(function(todoItems) {
var listItems = $.map(todoItems, function(item) {
return $('<li>')
.attr('data-todoitem-id', item.id)
.append($('<button class="item-delete">Delete</button>'))
.append($('<input type="checkbox" class="item-complete">').prop('checked', item.complete))
.append($('<div>').append($('<input class="item-text">').val(item.id))
.append($('<span class="timestamp">'
+ (item.createdAt && item.createdAt.toDateString() + ' '
+ item.createdAt.toLocaleTimeString() || '')
+ '</span>')));
});
$('#todo-items').empty().append(listItems).toggle(listItems.length > 0);
$('#summary').html('<strong>' + todoItems.length + '</strong> item(s)');
}, handleError);
}
function handleError(error) {
var text = error + (error.request ? ' - ' + error.request.status : '');
$('#errorlog').append($('<li>').text(text));
}
function getTodoItemId(formElement) {
return $(formElement).closest('li').attr('data-todoitem-id');
}
// Handle insert
$('#add-item').submit(function(evt) {
var textbox = $('#new-item-text'),
itemText = textbox.val();
if (itemText !== '') {
todoItemTable.insert({ text: itemText, complete: false }).then(refreshTodoItems, handleError);
}
textbox.val('').focus();
evt.preventDefault();
});
// Handle update
$(document.body).on('change', '.item-text', function() {
var newText = $(this).val();
todoItemTable.update({ id: getTodoItemId(this), text: newText }).then(null, handleError);
});
$(document.body).on('change', '.item-complete', function() {
var isComplete = $(this).prop('checked');
todoItemTable.update({ id: getTodoItemId(this), complete: isComplete }).then(refreshTodoItems, handleError);
});
// Handle delete
$(document.body).on('click', '.item-delete', function () {
todoItemTable.del({ id: getTodoItemId(this) }).then(refreshTodoItems, handleError);
});
// On initial load, start by fetching the current data
refreshTodoItems();
});
I was trying to access the system properties from within the API scripts and found this and thought it was useful and relevant: http://www.brandonmartinez.com/2014/10/22/retrieve-system-properties-in-azure-mobile-services-javascript-backend/
Basically you can do this (example from the post):
myTable.read({
systemProperties: ['__createdAt', '__updatedAt'],
success: function(tableEntries) {
// So on and so forth
}
}

Passing values between two javascript in a html

I have a case where i need to load a char based on the input from another javascript. But it doesn't work in my case. I have added the code below:
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart', 'table']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
var json = $.ajax({
url: fileURL, // make this url point to the data file
dataType: 'json',
cahce:false,
async: false
}).responseText;
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(json);
var options = {
title: graphTitle,
is3D: 'true',
width: 800,
height: 600
};
var tableOptions = {
title: 'App Listing'
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
and I pass the value for graphtitle and fileURL as below:
<script type="text/javascript">
$(document).ready(function () {
var fileURL = "";
var graphTitle = "";
function showDiv() {
if($firstCheck) {
var selText;
$("#dd4 li a").show(function () {
selText = $(this).text();
});
if(selText !== "Factor"){
if(selText == "IA Architecture Usage"){
fileURL = "get_json.php";
graphTitle = "IA Architecture Variation";
}else if(selText == "Tablet to Phone"){
fileURL = "get_tablet_support.php";
graphTitle = "Tablet Usage Variation";
}
document.getElementById('chart_div').style.display = "block";
}
}else{
document.getElementById('chart_div').style.display = "none";
}
}
</script>
Both these javascript are within the same file. I can't pass the fileURL and graphTitle when I used the above code. Any idea how to solve this issue?
Use global variables with window. E.g.
$(document).ready(function () {
window.fileURL = "";
window.graphTitle = "";
});
Don't specify "var" or it will only be within the scope of the function.
EDIT: Also make sure that the script in which your variables are assigned initially is before the other one.
How about something a bit more OO oriented (not really OO, but less inline code) ? It's cleaner and easier to read/maintain ..example could still use some work, but i"m sure you get the idea.
function loadChart(title, url) {
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart', 'table']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
var json = $.ajax({
url : url, // make this url point to the data file
dataType: 'json',
cahce : false,
async : false
});
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(json);
var options = {
title : title,
is3D : 'true',
width : 800,
height: 600
};
var tableOptions = {
title: 'App Listing'
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
}
$(document).ready(function () {
var fileURL = "";
var graphTitle = "";
function showDiv() {
if($firstCheck) {
var selText;
$("#dd4 li a").show(function () {
selText = $(this).text();
});
if(selText !== "Factor") {
if(selText == "IA Architecture Usage"){
fileURL = "get_json.php";
graphTitle = "IA Architecture Variation";
} else if(selText == "Tablet to Phone"){
fileURL = "get_tablet_support.php";
graphTitle = "Tablet Usage Variation";
}
document.getElementById('chart_div').style.display = "block";
}
} else {
document.getElementById('chart_div').style.display = "none";
}
loadChart(graphTitle, fileURL);
}
}
btw i think you have an error in your code: .responseText seems pretty useless to me, and most likely throws an error in itself. Also i have no idea who is calling showDiv() in the code. From the example, i'd say it never fires.
