generaly i ask exactly the same question as here:
Safari extension: Event for a completely new tab?
in this answer (case 3) he guide to listen click event inside inject.js.
can someone show this implementation?
Here's an implementation I used for one of my previous extensions:
Create a global.html file, and inside the Extension Builder, select that file under the Extension Global Page section:
Source for global.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>My Extension</title>
</head>
<body>
<script>
function messageHandler(event) {
var newTab = null;
var url = null;
if (event.name === "open_new_tab") {
url = event.message;
newTab = safari.application.activeBrowserWindow.openTab();
newTab.url = url;
}
}
safari.application.addEventListener("message", messageHandler, false);
</script>
</body>
</html>
Create an extension.js file, and add it to the Injected Extension Content -> End Scripts section:
Source for extension.js:
(function() {
// ... rest of you extension code
openNewTabWithUrl("http://google.com")
function openNewTabWithUrl(url) {
safari.self.tab.dispatchMessage("open_new_tab", url);
}
}());
This will send a message containing a URL from your extension.js to global.html, which will pick up the message and open the new tab.

I have a html page with images, tables and some styling with Bootstrap 4. I tried to convert the pages to pdf using the JsReportMVCService, the pdf doesnot load with the proper css class from bootstrap.
HTML CONTENT
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>WeekelyReport</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
</head>
<body>
<div class="jumbotron">
<h1> Hello John Doe,</h1>
<p>
This is a generic email about something.<br />
<br />
</p>
</div>
</body>
</html>
ASP.NET CORE IMPLEMENTATION
var generatedFile = await GeneratePDFAsync(htmlContent);
File.WriteAllBytes(#"C:\temp\hello.pdf", generatedFile);
async Task<byte[]> GeneratePDFAsync(string htmlContent)
{
var report = await JsReportMVCService.RenderAsync(new RenderRequest()
{
Template = new Template
{
Content = htmlContent,
Engine = Engine.None,
Recipe = Recipe.ChromePdf
}
});
using (var memoryStream = new MemoryStream())
{
await report.Content.CopyToAsync(memoryStream);
return memoryStream.ToArray();
}
}
How my Pdf Looks after the conversion to PDF.
It is possible to convert to pdf with the same bootstrap 4 layout? or am i missing something during the conversion here?
The pdf printing uses print media type and the bootstrap has quite different styles for printing. This causes that the pdf looks different than html, but it looks the same as you would print it. I would generally not recommend using responsive css framework as bootstrap for printing static pdf, but it is of course your choice.
To make your example looking the same on pdf you just need to change the media type on the chrome settings.
var report = await JsReportMVCService.RenderAsync(new RenderRequest()
{
Template = new Template
{
Content = htmlContent,
Engine = Engine.None,
Recipe = Recipe.ChromePdf,
Chrome = new Chrome {
MediaType = MediaType.Screen,
PrintBackground = true
}
}
});
make sure you have the latest jsreport.Types#2.2.2
I am trying to embed "HelloWorld" module into existing HTML page.
I found that module is rendered asynchronously (i don't get rendered element
immediately after calling "embed").
I want to use Elm in an existing project and rewrite some parts of JavaScript
in Elm. But asynchronous rendering makes things difficult.
Is there a way to render it synchronously?
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="app.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
var appContainer = document.createElement('div');
Elm.HelloWorld.embed(appContainer);
console.log('Html: ' + appContainer.innerHTML); // Will print an empty string
setTimeout(function() {
console.log('Html: ' + appContainer.innerHTML); // Will print "Hello, World!"
}, 0);
</script>
</body>
</html>
HelloWorld.elm
module HelloWorld exposing (main)
import Html exposing (text)
main =
text "Hello, World!"
UPD: Removed redundant code.
Nowadays, Elm doesn't expose this kind of hook.
You have basically two different approaches, one based on events and the other based on timing (the setTimeout() method you are already using).
The event-driven approach involves the MutationObserver Api.
Creating a new MutationObserver, you can observe the HTML Node onto which you run the Elm module: this way, you have a hook on the DOM update.
A naive check would be checking against the children's list of the appContainer:
<body>
<div id="myDiv"></div>
<script type="text/javascript">
var appContainer = document.getElementById('myDiv');
var mo = new MutationObserver(function(mutationRecords, instance) {
for (var i = 0; i < mutationRecords.length; i += 1) {
if (mutationRecords[i].addedNodes.length > 0) {
// a trivial check
console.log('Html: ' + appContainer.innerHTML);
// stop observing, if not needed anymore
mo.disconnect();
}
}
});
mo.observe(appContainer, { childList: true });
Elm.HelloWorld.embed(appContainer);
</script>
</body>
Note that the above code is assuming that your HelloWorld module is adding children to the appContainer, so you should modify it conveniently:
module HelloWorld exposing (main)
import Html exposing (p, text)
main =
p [] [ text "Hello, World!" ]
Sencha Touch application has requires:[] option to specify the list of controllers and models and stores etc that are loaded that we need for the application to work but is there a way to execute something that we need even before the loading of the dependencies. FOr e.g. I need the Browsers Language even before the loading of all dependencies. So is it possible to do?
Keep in mind: Sencha Touch is nothing but JavaScript.
You can add some script in your index.html in front of the script tag that loads the sencha microloader.
<!DOCTYPE HTML>
<html manifest="" lang="en-US">
<head>
<meta charset="UTF-8">
<title>FNL</title>
<style type="text/css">
<!-- sencha stuff -->
</style>
<script id="myScript" type="text/javascript" src="myScript.js"></script>
<!-- The line below must be kept intact for Sencha Command to build your application -->
<script id="microloader" type="text/javascript" src=".sencha/app/microloader/development.js"></script>
</head>
<body>
<div id="appLoadingIndicator">
<div></div>
<div></div>
<div></div>
</div>
</body>
</html>
I added some lines to the ST Microloader:
this.css = processAssets(manifest.css, 'css');
// Load language strings
var xhr = new XMLHttpRequest();
xhr.open('GET', 'api/Settings', false);
xhr.send(null);
var settings = eval("(" + xhr.responseText + ")");
Lang = settings.Translations[0];
Options = settings.Options[0];
// End Load Language Strings
this.js = processAssets(manifest.js, 'js');
In ExtJS i accomplished this by loading a Dependency class first
Ext.require([
'MyApp.Dependencies',
..
]);
so the Dependecies class is loaded before all controllers which looks like this
Dependencies.js:
Ext.define('MyApp.Dependencies', {
singleton: true,
init: function() {
// load translation data
}
});
MyApp.Dependecies.init();
and for completition my init function looks something like this:
inti: function(){
function loadScriptSync(url) {
var xhrObj = new XMLHttpRequest();
// open and send a synchronous request
xhrObj.open('GET', url, false);
xhrObj.send('');
// add the returned content to a newly created script tag
var se = document.createElement('script');
se.type = "text/javascript";
se.text = xhrObj.responseText;
document.getElementsByTagName('head')[0].appendChild(se);
}
var language = this.getLanguage();
loadScriptSync("resources/locale/locale." + language + ".js");
}
I'm trying to create a very basic photo upload feature. I've followed a lot of tutorials and examples online but I'm having some issues in actually getting it to work.
Currently I receive the following errors:
2012-03-26 17:37:02.107 Upload[84710:13403] fileData length: 72154
2012-03-26 17:37:02.119 Upload[84710:13403] File Transfer Error: unsupported URL

This is my Phonegap HTML file:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>File Transfer Example</title>
<script type="text/javascript" charset="utf-8" src="cordova-1.5.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
function onDeviceReady() {
// Do cool things here...
}
function getImage() {
// Retrieve image file location from specified source
navigator.camera.getPicture(uploadPhoto, function(message) {
alert('get picture failed');
},{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
options.chunkedMode = false;
var ft = new FileTransfer();
ft.upload(imageURI, "hosting.domain.co.uk/ios/upload.php", win, fail, options);
}
function win(r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
alert(r.response);
}
function fail(error) {
alert("An error has occurred: Code = " = error.code);
}
</script>
</head>
<body>
<button onclick="getImage();">Upload a Photo</button>
</body>
</html>
And this is my upload.php file:
<?php
print_r($_FILES);
$new_image_name = "namethisimage.jpg";
move_uploaded_file($_FILES["file"]["tmp_name"], "/var/www/vhosts/domain.co.uk/subdomains/hosting/httpdocs/ios/uploads".$new_image_name);
?>
Is there anything obvious that I'm doing wrong?
Thanks a lot
Jon
You are using fileURI to upload the photo that is why you are getting the unsupported file format error. This is because the fileURI will be something of the format file://localhost/xx1.jpg. This will be unsupported by the uploader function on the server side.
Javascript can't access the native file system
Javascript does not have direct access to the underlying file system therefore it cannot upload via file transfer in case of phonegap.
The Solution
Your best bet is to instead upload the base64 encoded string for the image. You can obtain the base64 encoded image by using the option navigator.camera.DestinationType.DATA_URL for destinationType. This will return the base64 encoded string. And this can be easily sent over json to the server with the associated metadata like jpg or png format and filename etc.
Take a look here of a successful use of phonegap and an online image hosting facility provided by imgur.
Good Luck and Cheers
I see many references to this error on the web, but they are not helping me. I guess i am new enough to this that i need a specific answer for my problem.
I am attaching the first portion of code on a page that i am running. the last line i show is the line that is creating the error stating in the title. Please let me know if you have any suggestions.
Thank you!

From your comment, you used declarative syntax to create the dijit, i.e. <button id="load-button" dojoType="dijit.form.Button" onclick="loadKml();">. If the declarative syntax is used, the dijit is actually created after the page is loaded. So you should put the code to use the dijit in the Dojo's load callback, i.e. inside of dojo.addOnLoad callback.
But your code is bad formatted and mingled with Google Maps load callback, it's not easy to inspect the code. My suggestion would be to wrap the dijit.byId('load-button').setDisabled(true); with dojo.addOnLoad, like below:
dojo.addOnLoad(function() {
dijit.byId('load-button').setDisabled(true);
});
It means that you've got a dojo object rather than a dijit object -- or possibly no object named load-button at all, since it's not clear from this where load-button is being created. Make sure there is an object with id="load-button" that was created with dijit.
