I have following simple code that tests Dropbox datastore API:
<!doctype html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript" src="https://www.dropbox.com/static/api/dropbox-datastores-1.1-latest.js"/></script>
<script type="text/javascript" charset="utf-8">
window.addEventListener('load', function() {
client = new Dropbox.Client({key: 'mykey', token: 'mytoken'});
var manager = client.getDatastoreManager();
manager.openDefaultDatastore(function(err, store) {
if (!err) {
setInterval(function() {
var table = store.getTable('foo');
var record = table.get('bar');
record.update({baz: 0});
console.log(record.getSize());
}, 1000);
}
});
});
</script>
</head>
<body>
</body>
</html>
If i execute it, the reported record size will start increasing by 100 bytes on each update. Upon reaching 100kb code will fail with internal "record too big" error. Is it any way to update single Dropbox Datastore record in a loop without memory leaks? Maybe i'm doing something wrong?
Bug in the library, need to wait for a fix: https://forums.dropbox.com/topic.php?id=119469

I can't figure out how to get access to the full source of the HTML page including iframes. It should be similar to what we see in DevTools > Elements, but via Electron.
By source I mean either text representation of the DOM (including content of all iframes on the page), or the list of all elements and having a way to get access to their text-representations.
Any help is highly appreciated! Thanks.
If you're just looking to get a string of all the HTML, you can do so via the executeJavaScript API:
const {app, BrowserWindow, dialog} = require('electron')
async function createWindow () {
const mainWindow = new BrowserWindow()
await mainWindow.loadFile('index.html')
const result = await mainWindow.webContents.executeJavaScript("document.documentElement.outerHTML");
dialog.showMessageBox(mainWindow, {
message: result
});
}
app.whenReady().then(() => {
createWindow()
app.on('activate', function () {
if (BrowserWindow.getAllWindows().length === 0) createWindow()
})
})
app.on('window-all-closed', function () {
if (process.platform !== 'darwin') app.quit()
})
For an HTML page like:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link href="./styles.css" rel="stylesheet">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
We are using Node.js <span id="node-version"></span>,
Chromium <span id="chrome-version"></span>,
and Electron <span id="electron-version"></span>.
<iframe src="https://google.com/chrome"></iframe>
</body>
</html>
You'll get a dialog like this:
It is not however possible to just grab DOM elements in the main process that you can manipulate.
I have a little NodeJS server, which an index.html invites me over serve-static.
Is it somehow possible that are contained in the index.html functions of NodeJS?
Theoretically, I could of course solve the whole problem with express routes, but possibly there is also another solution
var serve = serveStatic(__dirname+"/../Websites", {'index': ['index.html']});
// Create server
var server = https.createServer(options,function onRequest (req, res) {
serve(req, res,finalhandler(req, res));
})
// Listen
server.listen(443, function(){
console.log('WebServer running on 443...');
});

I have tried so many URL variations for Flickr and all attempts have failed to load my image gallery into my own webpage.
I am pretty sure its the URL. If I replace the URL with:
"api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?"
all works fine to load public photos from Flickr, but to load my own album (URL below), it won't work.
Yes I have a valid API from Flickr. I also checked the script syntax in "jsbin.com" and all of that is good.
Can anyone help resolve this?
Here is the jQuery script:
(function() {
var flickerUrl = "https://api.flickr.com/services/rest/?&method=flickr.people.getPublicPhotos&api_key=<removed by edit>&user_id=135938131#N02&format=json&jsoncallback=?";
$.getJSON(flickerUrl)
.done(function(data) {
$.each(data.items, function(i, item) {
var image = $("<img>")
.attr("src", item.media.m)
.attr("title", item.title);
$("<a>")
.attr("href", item.link)
.attr("target", "_blank")
.html(image)
.appendTo("#images");
if ( i === 8 ) {
return false;
}
});
});
})
();

I want to make a redirection with jQuery mobile right just after the page loads.
Something like this
<?php
... some php stuff here
?>
<html>
<head>
<link rel="stylesheet" href="css/jquery.mobile-1.1.1.min.css" />
<script src="js/jquery-1.7.2.min.js"></script>
<script src="js/jquery.mobile-1.1.1.min.js"></script>
</head>
<script>
$.mobile.changePage("index.php");
</script>
But nothing happens...
Thanks!
Nothing happens because jQueryMobile hasn't done it's magic yet.
Try:
$(document).bind('pageinit', function() {
$.mobile.changePage("index.php");
});
You could also try some of the events listed at http://jquerymobile.com/demos/1.1.1/docs/api/events.html
Edited following comment:
The following works as expected for me:
<html>
<head>
<title>My Page</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>
<script>
$(document).bind('pageinit', function() {
$.mobile.changePage("#pageTwo");
});
</script>
</head>
<body>
<div id="firstPageId" data-role="page">
Page One
</div>
<div id="pageTwo" data-role="page">
Page Two
</div>
</body>
</html>
You can use plain ol' JavaScript for this, you don't need jQuery:
window.location = "index.php";
To do it after the page loads, add a $(document).ready() handler:
$(document).ready(function () {
window.location = "index.php";
});
Try, adding your page-id in the script with .live, something like this:
$('#mainpage').live('pageinit', function (event) {
alert("hi");
//$.mobile.changePage("index.php");
});
Here is the full example: http://jsfiddle.net/KyKFE/
On the other hand, you can also use just plain javascript function or php (if .php page) to do the redirection. They are many different ways to do this.
Please try this to end of your page and before </body> tag,
<script>
$(window).load("index.php", function() {
// stuff or not
});
</script>
I hope help you. :)
I'm working on installing a PhoneGap plugin on an iPhone. The page for the plugin I am attempting to install can be seen here: https://github.com/phonegap/phonegap-plugins/tree/master/iPhone/MessageBox.
I believe I have narrowed down my problem to incorrectly working with the JavaScript file. I am including it on my HTML page like so:
<script language="javascript" type="text/javascript" src="MessageBox.js"></script>
The rest of my HTML page is this:
<script type="text/javascript">
alert("test1");
var messageBox = window.plugins.messageBox;
alert("test2");
messageBox.alert('Title', 'Message', function(button) { console.warn('alert', [this, arguments]); });
</script>
I see an alert saying test1, but not the second alert. This makes me think that the error is on the line:
var messageBox = window.plugins.messageBox;
However, I'm not quite sure what I should be doing differently. From what I can tell, I've done all the necessary steps as described on the plugin's documentation page, seen here:
https://github.com/phonegap/phonegap-plugins/blob/master/iPhone/MessageBox/README.md
(As expected, I also do not see the output of the messageBox.alert... line when viewing this through the iOS simulator.)
I would appreciate any help with this issue, thanks!
NOTE: my initial thread regarding this topic can be seen here: Trouble Installing PhoneGap Plugin
EDIT: I should also add that I have the exact same problem when trying to install a different (but similar) plugin, known as "Prompt"
EDIT2: Here's my index.html:
<script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script>
<script type="text/javascript" src="MessageBox.js"></script>
<script type="text/javascript">
function onBodyLoad()
{
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady()
{
navigator.notification.alert("PhoneGap is working");
window.location.href="otherpage.html";
}
</script>
The problem is that when you try to create your MessageBox, PhoneGap is not ready yet.
You just need to wait for PhoneGap to be ready before you execute your code :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
window.location="otherpage.html";
}
</script>
</head>
<body>
</body>
</html>
Then, on otherpage.html :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script>
<script type="text/javascript" charset="utf-8" src="MessageBox.js"></script>
</head>
<body onload="onLoad()">
<script type="text/javascript" charset="utf-8">
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// PhoneGap is loaded and it is now safe to make calls PhoneGap methods
//
function onDeviceReady() {
console.log("onLoad");
var messageBox = window.plugins.messageBox;
messageBox.alert('Title', 'Message', function(button) { console.warn('alert', [this, arguments]); });
}
</script>
</body>
</html>
I tested it on PhoneGap 1.4.1
