I am looking for the easiest way to populate a data table in google visualizations using either a json file or a local spreadsheet(.xlsx).
heres my code:
<!DOCTYPE html>
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable.fromJSON(sampleData.json,0.6);
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, {width: 400, height: 240});
}
</script>
</head>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
</body>
</html>
Heres my json file:
{
"cols": [
{"id":"","label":"Topping","pattern":"","type":"string"},
{"id":"","label":"Slices","pattern":"","type":"number"}
],
"rows": [
{"c":[{"v":"Mushrooms","f":null},{"v":3,"f":null}]},
{"c":[{"v":"Onions","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Olives","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Zucchini","f":null},{"v":1,"f":null}]},
{"c":[{"v":"Pepperoni","f":null},{"v":2,"f":null}]}
]
}
When I run my code in my browser, I get
"Uncaught ReferenceError: sampleData is not defined"
Anyone know how I can make this work?
Thanks in advance
You COULD simply place the contents of your JSON file right inline there in your HTML where the string "sampleData.JSON" is. That is, take out "sampleData.JSON" and replace it with the entire contents of your JSON file. I'm pretty sure you'll make some progress if you do this.
Try putting sampleData.json in quotes, assuming that the filename is sampleData.json and is in the same folder as your HTML.
var data = new google.visualization.DataTable.fromJSON('sampleData.json',0.6);

I have an HTML code that imports a LOCAL but UPDATABLE *.json content, and it must be updated automatically when the *.json file is updated.
This is the *.HTML code:
<html>
<head>
<script type="text/javascript" src="sample.json"></script>
<script type="text/javascript" >
function load() {
setInterval(function () {
var mydata = JSON.parse(data);
var div = document.getElementById('data');
div.innerHTML = mydata[0].location.altitude;
}, 100);}
</script>
</head>
<body onload="load()">
<div id="data">
</div>
</body>
</html>
and the adapted sample.json file is:
data = '[{"location": {"altitude": 40}}]';
I just wanna see the altitude is changing in the browser(HTML) whenever the sample.json file is updated.
Now the HTML works but only ONCE, I wanna make it dynamic.
What should I do to make the function setInterval work correctly? or maybe this function works only for local changes, not external ones.

If you want the browser to get data from a URL even interval, then you need to write code which gets data from a URL in the interval. e.g. with the Fetch API. (At which point you should make it JSON instead of JS).
However HTTP is not fast. You do not want to be polling over HTTP every 100ms. Consider using Websockets to push the data from the server when it changes instead of polling.
I have html file which has 3 script tags. I want to put these script tags in my vue.js file.
i have added the html div element to by vue js file and it is getting rendered. but i am just not able to load script from html into vue.
Below is my html file.
<html>
<body>
<script type="text/javascript">
mxBasePath = "../editors/pure";
</script>
<script type="text/javascript" src="../editors/pure/js/mxClient.js"></script>
<script src="../editors/dist/main.js"></script>
</body>
</html>
I have tried to add my scripts in the mounted section of vue. Below is my vue.js file
import * as client from '../editors/pure/js/mxClient.js'
import * as mains from '../editors/dist/main.js'
mounted () {
var z = document.getElementById('geApp')
let recaptchaScript = document.createElement('script')
recaptchaScript.setAttribute('src', client)
z.appendChild(recaptchaScript)
let processes = document.createElement('script')
processes.setAttribute('src', mains)
z.appendChild(processes)
let basepath = document.createElement('script')
basepath.innertext = 'mxBasePath = "../editors/pure"'
z.appendChild(basepath)
},
But i am getting the error as file not found.. I solved the problem by importing the src file but now i am getting the error as "one of the functionality is not defined."
Please can anyone help me in adding the scripts to vue.js file
I'm having a problem trying to load a graph form json using JointJS. I know the theory (https://resources.jointjs.com/tutorial/serialization), however, I still do not know how to show a graph.
This is my html file:
<!-- JointJS libraries omitted for space -->
<script src="https://code.jquery.com/jquery-1.12.4.min.js" integrity="sha256-ZosEbRLbNQzLpnKIkEdrPv7lOy9C27hHQ+Xp8a4MxAQ=" crossorigin="anonymous"></script>
<script type="text/javascript">
function read_json() {
$.getJSON("/jointsjdemo/demo.json", function(data) {
var graph = new joint.dia.Graph;
graph.fromJSON(data);
var paper = new joint.dia.Paper({
el: document.getElementById('myholder'),
model: graph,
width: 600,
height: 100,
gridSize: 1
});
});
}
read_json();
</script>
And this is my json file:
{"cells":[{"type":"standard.Rectangle","position":{"x":100,"y":30},"size":{"width":100,"height":40},"angle":0,"id":"42a7f123-1f0d-4d06-b49e-8cbcbbb17e23","z":1,"attrs":{"body":{"fill":"blue"},"label":{"fill":"white","text":"Hello"}}},{"type":"standard.Rectangle","position":{"x":400,"y":30},"size":{"width":100,"height":40},"angle":0,"id":"6ecac186-b9c1-4755-97db-704cd9b9156f","z":1,"attrs":{"body":{"fill":"blue"},"label":{"fill":"white","text":"World!"}}},{"type":"standard.Link","source":{"id":"42a7f123-1f0d-4d06-b49e-8cbcbbb17e23"},"target":{"id":"6ecac186-b9c1-4755-97db-704cd9b9156f"},"id":"fa23e165-3c9f-46f8-9fe9-e6660d4086ca","z":2,"attrs":{}}]}
When a load the web page, it shows nothing on screen. I'm deployed my app in Apache Tomcat. Using Chrome Developer Tools, no errors are shown in Console.
I dont know what I'm missing.
Any help please? The json file was generated through toJSON command.
P.D. I think it should be better to hire someone, but I'm still trying to do this.

I don't exactly understand what you mean. If you are trying to capture console output, here is a simple example:
var output = [];
var saved = console.log;
console.log = function(arg) {
output.push(arg);
saved(arg);
};
console.log('Hello, world!');
What this does is replace the inbuilt console.log method with a new one that captures console output.
Why we have a variable called saved is a backup of the old console.log before we relaced it, so it'll still be able to write to the console.
Ok, this is my final tango with this. Below I've listed the code. I'm able to get the value of the url and display it on screen for the current (active tab) in Google Chrome. Now all I have to do is pass that value as a parameter in the URL via JSON. My processing file resides on a our remote server - in php. Everything I've done with respect to this has worked to perfection. However, any attempts to pass the current url or any url as one of the parameters - e.g. ?format=json&url=http://something.com&callback=? - results in nothing. I'm not sure if what I'm doing is wrong or if it is even possible. The important thing to note is that all we are looking to do is pass the url to a remote server for storage, processing etc and send back results. I have everything working but I just can't seem to get the url to pass as a parameter.

}

<script type="text/javascript">

var timeService =

Again, all the JSON works fine when I'm testing other code. Even if I put in a NON-URL value as a parameter for url=..... it throws the appropriate error. However, it will not accept a URL for some reason.
Any feedback will be greatly appreciated.
Thanks,

Try encoding and decoding the url.
