I've embedded data studio report on a html page. I refresh the iframes' after an interval, but the reports do not update. The report on the embedded page gets updated only by going to the report on data studio's website and clicking "Refresh data" icon.
How can the report on html page be refreshed without manually clicking Refresh data icon on data studio website?
HTML page:
<!DOCTYPE html>
<html lang="en">
<head>
<title></title>
</head>
<body>
<div>
<iframe id="TODOcombined" width="800" height="600" src="https://datastudio.google.com/embed/reporting/1L5PqnHOl0kv3-bwMMVGcNgBi0cdaSMUN/page/Kj0j" frameborder="0" style="border:0" allowfullscreen></iframe>
</div>
<div>
<iframe id="TODOmultipage" width="800" height="600" src="https://datastudio.google.com/embed/reporting/19ErM9ElRIHD18oBKo0gGTdrmU5ayXn3H/page/Kj0j" frameborder="0" style="border:0" allowfullscreen></iframe>
</div>
<script>
function refreshFrames() {
console.log("Refreshing frames at:" + new Date);
document.getElementById('TODOcombined').src = document.getElementById('TODOcombined').src;
document.getElementById('TODOmultipage').src = document.getElementById('TODOmultipage').src;
}
setInterval(refreshFrames, 20000);
</script>
</body>
</html>
When you create a datastudio report you can control whether you use caching (at the report settings level) and how fresh you want your data to be (at the connection level, with options ranging between 1, 4 and 12 hours).
Simply refreshing the page does not override these so you will need to change them to meet your needs.
See Manage Data Studio data freshness for details.
Hello, the first solution could be install a plugin in the chrome extensions called "Data Studio Auto Refresh" site here and set it up. (PD:For use this plugin its necessary to keep your page the chrome available, you could use one server for that or whatever you decide)
The second solution is create a script in jquery, ajax etc to reload the mark element without refresh the whole page.
Hope it works!

I am using default cache setting which is 24hours.
However, when I refresh the page, I see updated html page every time. Why the file is not cached for 24hrs. I didn't set any invalidation mechanism.
Here's the URL: https://dhr5io29ip73w.cloudfront.net/
html file content:
<html>
<h1>Test</h1>
<p id='myTime'></p>
<script>
var d = new Date().toLocaleTimeString();
document.getElementById('myTime').innerHTML = d;
</script>
</html>
Your page includes JavaScript. The JavaScript code runs in the web browser. That means each time you load the page, your web browser executes those JavaScript statements in the <script> tag which includes updating the page with the current time.
CloudFront just caches the raw HTML of the page. It doesn't cache the rendered result.
I Want to develop a flask navigation bar like Google Contacts.
I Want to Render a particular HTML page inside the red box (as in the picture) when I click each of the navigation buttons (the green box as in picture) without refreshing the page.

As #Klaus D. mentioned in the comments section, what you want to achieve can be done using Javascript only. Maybe your question were
How can I send a request to my server-side (to get or fetch some information) and receive back a response on the client-side without having to refresh the page unlike the POST method usually does?
I will try to address the aforementioned question because that's probably your case.
A potential solution
Use Ajax for this. Build a function that sends a payload with certain information to the server and once you receive back the response you use that data to dynamically modify the part of the web-page you desire to modify.
Let's first build the right context for the problem. Let's assume you want to filter some projects by their category and you let the user decide. That's the idea of AJAX, the user can send and retrieve data from a server asynchronously.
HTML (div to be modified)
<div class="row" id="construction-projects"></div>
Javascript (Client-side)
$.post('/search_pill', {
category: category, // <---- This is the info payload you send to the server.
}).done(function(data){ // <!--- This is a callback that is being called after the server finished with the request.
// Here you dynamically change parts of your content, in this case we modify the construction-projects container.
$('#construction-projects').html(data.result.map(item => `
<div class="col-md-4">
<div class="card card-plain card-blog">
<div class="card-body">
<h6 class="card-category text-info">${category}</h6>
<h4 class="card-title">
${item.title_intro.substring(0, 40)}...
</h4>
<p class="card-description">
${item.description_intro.substring(0, 80)}... <br>
Read More
</p>
</div>
</div>
</div>
`))
}).fail(function(){
console.log('error') // <!---- This is the callback being called if there are Internal Server problems.
});
}
Build a function that will fetch the current page via ajax, but not the whole page, just the div in question from the server. The data will then (again via jQuery) be put inside the same div in question and replace old content with new one.
Flask (Server-side)
''' Ajax path for filtering between project Categories. '''
#bp.route('/search_pill', methods=['POST'])
def search_pill():
category = request.form['category']
current_page = int(request.form['current_page'])
## Search in your database and send back the serialized object.
return jsonify(result = [p.serialize() for p in project_list])
Thank you #CaffeinatedCod3r,#Klaus D and #newbie99 for your answers.
I Figured it out. instead of using Flask we can use Angular JS Routing for navigation.
Here is the example that i referred:
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular-route.js"></script>
<head>
<base href="/">
</head>
<body ng-app="myApp">
<p>Main</p>
Banana
Tomato
<p>Click on the links to change the content.</p>
<p>Use the "otherwise" method to define what to display when none of the links are clicked.</p>
<div ng-view></div>
<script>
var app = angular.module("myApp", ["ngRoute"]);
app.config(function($routeProvider, $locationProvider) {
$routeProvider
.when("/banana", {
template : "<h1>Banana</h1><p>Bananas contain around 75% water.</p>"
})
.when("/tomato", {
template : "<h1>Tomato</h1><p>Tomatoes contain around 95% water.</p>"
})
.otherwise({
template : "<h1>Nothing</h1><p>Nothing has been selected</p>"
});
$locationProvider.html5Mode(true);
});
</script>
</body>
</html>
By Using $locationProvider.html5Mode(true) i was able to remove the # from the URL.
I have my own web applications and need to implement reporting in it.
So I want to know how can we embed the graph generated by apache superset in my web application/project ?
Quick Answer:
You can insert it with an HTML IFrame tag.
For example if the Url of your dashborad is
http://52.59.247.208:8088/superset/dashboard/1/
Add simply the following suffix "?standalone=true" and add it in your HTML code like:
<html>
<head>
<title>Testing Charts</title>
</head>
<body>
<h1>Testing IFrame</h1>
<iframe
width=100%
height=100%
frameBorder="0"
src="http://52.59.247.208:8088/superset/dashboard/1/?standalone=true"
>
</iframe>
</body>
But first you have to edit your superset_config.py file by adding following line, if you want to use it without any problems:
SESSION_COOKIE_SAMESITE="None"
I am trying to get cloudflare stream to work in angular. I have tried the solution given here: Angular attribute for HTML stream.
However, it is always a hit or a miss:
Out of 10 reloads, one loads the player.
But anytime I make a
change to the <stream> tag, and angular re-compiles, the player is
loaded. After this if I refresh the browser, it is a blank screen
again.
The component which shows the video is deep in the tree and the component belongs to a module that is lazy loaded:
In the index.html file:
<!doctype html>
<html lang="en">
<head>
...............
</head>
<body>
<app-root></app-root>
</body>
<script src="https://embed.cloudflarestream.com/embed/r4xu.fla9.latest.js" id="video_embed" defer="" async=""></script>
</html>
In the videoFile.component.ts:
<stream src="5d5bc37ffcf54c9b82e996823bffbb81" height="480px" width="240px" controls></stream>
Found a solution here: https://github.com/angular/angular/issues/13965
So everytime the component loads, the script is removed and reattached using ngOninit, like so:
document.getElementById("video_embed").remove();
let testScript = document.createElement("script");
testScript.setAttribute("id", "video_embed");
testScript.setAttribute("src", "https://embed.cloudflarestream.com/embed/r4xu.fla9.latest.js");
document.body.appendChild(testScript);
If anyone has any other solutions, please do let me know.
I have the following HTML page which works perfectly fine as a HTML page; however when I try put it into APEX by entering the code into a Region it just goes all wrong.
When the submit button is pressed, it takes the user to a new page with the IFRAME on rather than just refreshing the page as it does in a HTML page. The other issue is the aesthetics, it looks perfect in Firefox but in IE the IFRAME is half way down the page. When investigating in Firebug I see no attributes which would cause this.
Is there a method of embedding a HTML page into an APEX form page?
<!DOCTYPE html>
<html>
<body>
<head>
</head>
<form action="http://ukserver/orderlist.asp" target="orderResults">
Enter Order Number: <input id="ord" type="text" name="ord" maxlength="50" size="20"/>
<input type="submit" value="Submit"/>
</form>
<iframe id="orderResults" name="orderResults" src="blank.html" width="100%" height="50%">
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
This is the page in FireFox which as you can see looks ok.
This is the page in IE which is incorrect
Update:
The HTML page seems to work perfectly in the HTML header of the APEX page but its above my tabs and region which isnt the place where i want it. I tried to find an order (1112) and it returned the following 'File not found' which is correct.
Hi Tony, I created another IFRAME and i guess I'm half way there. I now just have to get the HTML form working, please see below:
It sounds like you have a PDF file in a folder on a server somewhere for each order. If the names of the files are predictable given the order number then you should be able to generate a link something like this:
1) Create an item to accept the order number e.g. P12_ORDER_NUMBER.
2) Create a button to submit the page
3) Create a report that displays when P12_ORDER_NUMBER is not null and selects:
select '//server/path/fileprefix' || :P12_ORDER_NUMBER || '.pdf' as url
from dual;
4) Convert the report column into a link via the column attributes so that clicking on it launches the file.
