I am new to JavaScript and Google BigQuery, so please forgive my ignorance. I am trying to write a javascript to collect data from one of the public databases on BigQuery. I found an answer to this at Obtaining BigQuery data from JavaScript code (the code for which I have pasted below) but when I saved the file as .html, replaced the client id and project number with mine, and tried to run it, I get the Authorize button and the page title. I click the Authorize button, and it disappears, but no query is run. Is there something else I was supposed to replace or is there something else I need to make this work? I saved the file as a .html, perhaps I should have saved it with a different extension?
I tried all three ways of creating a client id in the Google developers console and all gave me the same behavior.
I'm sure its just something silly that I am forgetting, but any advice would be greatly appreciated.
Here is the code given by Ryan Boyd, which I am unable to get working properly(which is surely my fault):
<html>
<head>
<script src="https://apis.google.com/js/client.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['geochart']});
</script>
<script>
// UPDATE TO USE YOUR PROJECT ID AND CLIENT ID
var project_id = '605902584318';
var client_id = '605902584318.apps.googleusercontent.com';
var config = {
'client_id': client_id,
'scope': 'https://www.googleapis.com/auth/bigquery'
};
function runQuery() {
var request = gapi.client.bigquery.jobs.query({
'projectId': project_id,
'timeoutMs': '30000',
'query': 'SELECT state, AVG(mother_age) AS theav FROM [publicdata:samples.natality] WHERE year=2000 AND ever_born=1 GROUP BY state ORDER BY theav DESC;'
});
request.execute(function(response) {
console.log(response);
var stateValues = [["State", "Age"]];
$.each(response.result.rows, function(i, item) {
var state = item.f[0].v;
var age = parseFloat(item.f[1].v);
var stateValue = [state, age];
stateValues.push(stateValue);
});
var data = google.visualization.arrayToDataTable(stateValues);
var geochart = new google.visualization.GeoChart(
document.getElementById('map'));
geochart.draw(data, {width: 556, height: 347, resolution: "provinces", region: "US"});
});
}
function auth() {
gapi.auth.authorize(config, function() {
gapi.client.load('bigquery', 'v2', runQuery);
$('#client_initiated').html('BigQuery client initiated');
});
$('#auth_button').hide();
}
</script>
</head>
<body>
<h2>Average Mother Age at First Birth in 2000</h2>
<button id="auth_button" onclick="auth();">Authorize</button>
<button id="query_button" style="display:none;" onclick="runQuery();">Run Query</button>
<div id="map"></div>
</body>
</html>
Update: I opened the Developer Tools in Chrome and found this error in the console:
Failed to execute 'postMessage' on 'DOMWindow': The target origin
provided ('file://') does not match the recipient window's origin
('null')
.
I tried editing in my Google Developer console as per these instructions: Google API in Javascript
Still same error.
Looks like you may need to add:
$('#query_button').show();
to the bottom of the auth() function
like so:
function auth() {
gapi.auth.authorize(config, function()
{
gapi.client.load('bigquery', 'v2', runQuery);
$('#client_initiated').html('BigQuery client initiated');
});
$('#auth_button').hide();
$('#query_button').show();
}
Searching for the error you got, I found this page:
Google API in Javascript
Based on the error you're receiving, my guess is that you either do not have your Javascript Origin configured properly on the Google API console you got your Client ID from, and/or you are trying to run your script from the file system instead of through a web server, even one running on localhost. The Google API client, near as I've been able to tell, does not accept authorization requests from the file system or any domain that has not been configured to request authorization under the supplied Client ID. --#citizenslave
It turns out it was a combination of things. I had the Javascript origin not configured properly, I didn't have all the scopes needed for my query, and I couldn't just open the html file in a browser, I needed to create an HTTP server.
So I changed the code to be:

};
function runQuery() {
var request = gapi.client.bigquery.jobs.query({
'projectId': project_id,
'timeoutMs': '30000',
'query': 'SELECT state, AVG(mother_age) AS theav FROM [publicdata:samples.natality] WHERE year=2000 AND ever_born=1 GROUP BY state ORDER BY theav DESC;'
});
request.execute(function(response) {
console.log(response);
var stateValues = [["State", "Age"]];
$.each(response.result.rows, function(i, item) {
var state = item.f[0].v;
var age = parseFloat(item.f[1].v);
var stateValue = [state, age];
stateValues.push(stateValue);
});
var data = google.visualization.arrayToDataTable(stateValues);
var geochart = new google.visualization.GeoChart(
document.getElementById('map'));
geochart.draw(data, {width: 556, height: 347, resolution: "provinces", region: "US"});
});
}
function auth() {
gapi.auth.authorize(config, function() {
gapi.client.load('bigquery', 'v2', runQuery);
$('#client_initiated').html('BigQuery client initiated');
});
$('#auth_button').hide();
}
</script>
</head>
<body>
<h2>Average Mother Age at First Birth in 2000</h2>
<button id="auth_button" onclick="auth();">Authorize</button>
<button id="query_button" style="display:none;" onclick="runQuery();">Run Query</button>

</body>
</html>
I fixed my Google Javascript Origins url to be http://localhost:8888/ and my Redirect uri to be http://localhost:8888/oauth2callback, opened a command prompt to run this command from the directory of my html file:
python -m SimpleHTTPServer 8888
and then went to localhost:8888 in my browser and clicked my html file there.
Thanks so much for all the feedback!
It worked perfectly! Now to change the query for my purposes!

I am using powerbi embedded. I successfully embed a report into my application using javascript. But I have to update embedded token manually every time.
Now I want to call rest API from my code so that token update automatically.
How to call API from my code to generate token and how to update token when it's going to expire?
My code is :
<html>
<head>
<title>Test</title>
<script src="/Scripts/powerbi.js"></script>
</head>
<body>
<div id="captionArea">
<h1>Power BI Embed test</h1>
</div>
<div id="embedContainer" style="height:500px">
</div>
<script>
(function () {
// Please change these values
var txtAccessToken = 'H4sIAAAAAA...';
var txtEmbedUrl =
'https://app.powerbi.com/reportEmbed?reportId=b21f4f90-e364-4b4c-9281-c5db87cdf3a5&groupId=a4781858-f...';
var txtEmbedReportId = 'b21f4f90-e364-4b4c-9281-c5db87cdf3a5';
var models = window['powerbi-client'].models;
var permissions = models.Permissions.All;
var config = {
type: 'report',
tokenType: models.TokenType.Embed,
accessToken: txtAccessToken,
embedUrl: txtEmbedUrl,
id: txtEmbedReportId,
permissions: permissions,
settings: {
filterPaneEnabled: true,
navContentPaneEnabled: true
}
};
var embedContainer = document.getElementById('embedContainer');
var report = powerbi.embed(embedContainer, config);
}());
</script>
</body>
</html>
I solved it. You can use MSAL or ADAL to generate an access token. I used MSAL.js 1.0 with implicit grant flow: https://learn.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-javascript-spa
After getting access token you can use ajax to call REST-API to generate embed token.
You can follow this Failed to load response data when tried to get access token from azure using JavaScript
I have a site with the following html code:
<div id="captchaDiv"></div>
<script src="https://www.google.com/recaptcha/api.js?onload=getCaptcha&render=explicit&sitekey=My_SITE_KEY"></script>
<script>
window.sd = function(token){
document.writeln(token);
}
getCaptcha = function(){
window.captcha = grecaptcha.render('captchaDiv',{
'sitekey' : My_SITE-KEY,
'callback': windows.sd,
'size':'invisible'
})
}
function onPageLoad(){
grecaptcha.ready(function(){
grecaptcha.execute();
});
}
window.onLoad(onPageLoad());
</script>
Now, when I browse and refresh this page, Google will provide a new token.
I have a test script as follow:
logger.info(RestAssured.get(page_url).then().extract().response().asString())
But instead of getting token, I am getting the page source code. Is there a way to this without creating a page to get the token?
I have the following code below :
<!DOCTYPE html>
<html>
<head>
<script src="http://connect.soundcloud.com/sdk.js"></script>
<script>
SC.initialize({
client_id: "f520d2d8f80c87079a0dc7d90db9afa9"
});
SC.get("/users/3207",{}, function(user){
console.log("in the function w/ " + user);
});
</script>
</head>
</html>
The code should print the user name to the console however whenever I run this, my console gives the error of :
Failed to load resource: The requested URL was not found on this server:
file://api.soundcloud.com/users/3207?client_id=f520d2d8f80c87079a0dc7d90db9afa9&format=json&_status_code_map%5B302%5D=200
However if I were to directly http://api.soundcloud.com/users/3207.json?client_id=f520d2d8f80c87079a0dc7d90db9afa9, then I get a valid JSON result.
Is there something incorrect with my how I am using the SC.get function?
Thanks
Well, you should test your index.html locally on a web-server like Apache and not by opening it as a file.
Working example
SC.initialize({
client_id: "f520d2d8f80c87079a0dc7d90db9afa9"
});
SC.get("/users/3207", {}, function(user) {
console.log("in the function w/ " + JSON.stringify(user));
var res = document.getElementById("result");
res.innerHTML = JSON.stringify(user);
});
<script src="http://connect.soundcloud.com/sdk.js"></script>
<div id="result"></div>
I'm building a phone app with Phonegap well, actually with Steroids.js which is built on top of Phonegap. Right now, all I want to do is retrieve the list of contact names and numbers from my phone upon the launching of my app. I took a look at the Contacts api here and I thought I was using it correctly. Below is the script I have inside of my head tags. What have I done wrong?
<script src="http://localhost/cordova.js"></script>
<script src="components/steroids-js/steroids.js"></script>
<script src="javascripts/application.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for device API libraries to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// device APIs are available
//
function onDeviceReady() {
var options = new ContactFindOptions();
options.filter = "";
var fields = ["displayName", "name"];
navigator.contacts.find(fields, onSuccess, onError, options);
}
function onSuccess(contacts) {
alert('ons');
for (var i = 0; i < contacts.length; i++) {
//trying to display contacts in an alert message when I launch my app
alert("Display Name = " + contacts[i].displayName);
}
}
// onError: Failed to get the contacts
function onError(contactError) {
alert('onError!');
}
</script>
In your above code your cordova.js file is misplaced somewhere.
like
<script src="http://localhost/cordova.js"></script>
You need to copy that cordova.js file into assest/www/ folder (like assest/www/cordova.js)
so it becomes like below in your html file
<script src="cordova.js"></script>
I was following along the tutorial at http://nowjs.com/doc when I encountered some errors.
<html>
<head>
<title>index.html</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"/>
<script src="http://localhost:8080/NowJS/now.js"></script>
<script>
$(document).ready(function(){
var name = prompt("what is your name?","");
now.receiveMessage = function(name,message){
alert(name+" "+message);
};
$('.butt').click(function(){
alert($('#put').val());
now.distributeMessage(name,$('#put').val());
$('#put').val('');
});
});
</script>
and for the server:
var fs = require('fs');
var sys = require('sys');
var server = require('http').createServer(function(req,response){
fs.readFile('index.html',function(err,data){
response.writeHead(200);
response.write(data);
response.end();
});
});
server.listen(8080);
sys.print('woot');
var everyone = require('now').initialize(server);
everyone.now.distributeMessage = function(name, message){
sys.print(name+" "+message);
everyone.now.receiveMessage(name,message);
};
I highly suspect it has something to do with my tag since there isnt anything at /NowJS/now.js.
Can someone enlighten me on this part:
On pages that you would like to use NowJS on, simply include this script tag in your HTML head: NowJS only works on pages that are served through the same http server instance that was passed into the initialize function above.
Thanks for your time.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"/>
script tags can't be self-closed.
In the docs the path in the script tag is lower-case, /nowjs/now.js, whereas in your snippet it is /NowJS/now.js, and so I guess this is the reason it doesn't work.
