I am having a problem connecting to a java application using my opera extension
I already did this extension in chrome a it work.
this is the code in javascritp in the popup.html
function AtribuirID(){
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var texto = xmlhttp.responseText;
var splitagem=texto.split("(user)");
localStorage.setItem('ID',splitagem[0]);
localStorage.setItem('Auxiliar',splitagem[1]);
}
}
xmlhttp.open("GET","http://localhost:10002?z=AtribuirID",true);
xmlhttp.send();
}
The problem is that i am getting a error Uncaught exception: DOMException: NETWORK_ERR in xmlhttp.send() and i cant access my application in java that suppose to be the server part.
I have already put the network="public private" in the config.xml but it didnt work
in config.xml file add this line: <access origin="*" subdomains="true"/> to allow any domain httprequest before </widget> tab, this solve the problem, if problems persist, open in opera browser tab "opera:config" and select "Users Prefs" and check "Allow File XMLHttpRequest" and restart. if have problem i can send you my opera extension working fine...

My script has some syntax error but instead of showing the error, PhantomJS doesn't display anything. Why Phantom JS isn't showing parse error if he script has errors?
In the following PhantomJS script (running via windows CMD), phantomJs hangs instead of showing error if there is a parsing error in the script.
var system = require('system');
var webpage = require('webpage').create();
console.log('starting script');
if (system.args.length === 0) {
console.log('no args');
} else {
system.args.forEach(function(arg,index){
console.log('arg is '+arg+' at '+index);
});
}
webpage.open('http://localhost:3000/cookie-demo',function(status){
if (status === 'success'){
console.log('success in opening page');
phantom.cookies.forEach(function(cookie,index){
for ( var key in cookie){
/*if instead of index, I use i as variable (undefined), the script just hangs!*/
console.log('[cookie:'+index+']'+key+'='+'cookie[key]');
}
});
phantom.exit(0);
}
else{
console.log('could not open the page');
phantom.exit(1);
}
});
If there is no syntax error in the script, I get following output
C:\Users\Manu\Documents\manu\programs\random>phantomjs --cookies-file=cookie-jar.txt phantomTest.js
starting script
arg is phantomTest.js at 0
success in opening page
[cookie:0]domain=cookie[key]
[cookie:0]expires=cookie[key]
[cookie:0]expiry=cookie[key]
[cookie:0]httponly=cookie[key]
[cookie:0]name=cookie[key]
[cookie:0]path=cookie[key]
[cookie:0]secure=cookie[key]
[cookie:0]value=cookie[key]
[cookie:1]domain=cookie[key]
[cookie:1]expires=cookie[key]
[cookie:1]expiry=cookie[key]
[cookie:1]httponly=cookie[key]
[cookie:1]name=cookie[key]
[cookie:1]path=cookie[key]
[cookie:1]secure=cookie[key]
[cookie:1]value=cookie[key]
But if there is a syntax error, I see nothing on the console and it doesnt exit
C:\Users\Manu\Documents\manu\programs\random>phantomjs --cookies-file=cookie-jar.txt phantomTest.js
PhantomJS version 2.0 and 2.1 will silently fail and hang if there are syntax errors. Use versions 1.9.8 or 2.5 betas. All downloads are here: https://bitbucket.org/ariya/phantomjs/downloads/
Better still migrate to Puppeteer which is a project with very similar API that uses headless Google Chrome underneath.
I am using the below code to open a local text file.It works fine in firefox but in safari i get the error as
'[object BlobConstructor]' is not a constructor (evaluating 'new Blob([xhr.response])').please help me by providing links.
var xhr = new XMLHttpRequest(),blob;
xhr.open('GET', 'example.txt');
xhr.responseType = 'arraybuffer';
xhr.onload = function(e) {
blob = new Blob([xhr.response]);
console.log(blob);
}
It's a bug in the older Safari/WebKits. Upgrade your browser or operating system.
Note: It still does not appear to accept ArrayBufferView's as arguments, but should be fine for normal arrays.
I have the following code to load a file after creating a web page which displays a WebGL canvas:
// Load ccconnect.js file
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if(xmlhttp.readyState == 4){
eval.call( Window, xmlhttp.response );
}
};
xmlhttp.open("GET","../ccconnect.js",true);
xmlhttp.send(null);
It works fine in Chrome but Safari brings up an error saying:
ReferenceError: Can't find variable: Window
on the line eval.call(...). The ccconnect.js code is displayed when I hover the mouse over 'response' on that same line when debugging so it seems to have retrieved it. Any idea what is wrong? I'm using Safari 5.1.5.
both window and Window is the global object both are understand by other browsers.
but when I checked in safari, it don't understand the variable Window. So my suggestion is replace Window with window.
I'm setting up a rails app and trying to implement login via Facebook JS SDK. Missing Omniauth already... :(
Anyway, what happens is that the dialog pops up, the user provides the login info, but then it redirects to https://www.facebook.com/connect/window_comm.php?_id=some-string&_relation=opener&auth_token=some-big-string, a blank screen. The pop-up doesn't close.
If I close it manually, though, and then refresh my page, I can see the login happened.
A curious thing is that on the first login, when permissions are asked for, everything works as expected, with the pop-up closing after permissions are granted or denied.
Tested on Chrome, FF, Safari and Opera. Consistent behaviour.
If I debug the blank redirect page on Chrome, there are two errors:
1) Unsafe JavaScript attempt to access frame with URL http://something from frame with URL https://something. Domains, protocols and ports must match. (note http x https...)
2) window_comm.php:7Uncaught TypeError: Cannot call method '_recv' of undefined
Here's the relevant code:
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'my-app-id',
status : true,
channelURL : 'http://localhost:3000/channel.html',
cookie : true,
oauth : true,
xfbml : true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
};
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/pt_BR/all.js"
fjs.parentNode.insertBefore(js, fjs);
}
(document, 'script', 'facebook-jssdk'));
</script>
<div class="fb-login-button" data-show-faces="true" data-width="400" data-max-rows="1" perms="offline_access"></div>
Thanks a lot for any light on this... Driving me nuts! =(
Edit: Can it be a bug on Facebook, since it is redirecting from http to https?
This answers Q.1) only. Facebook new requirements:-
switching to Oauth2.0 to fetch token_access
using SSL (ie: https://) to authenticate (hence the cross domain issues)
Also, I'd generally start with the code below to figure out the possible user state during the login process. That means clicking on anything and everything during testing phase.
FB.Event.subscribe('auth.authResponseChange', function(response) {
alert('The status of the session is: ' + response.status);
});
Right now I'm in the process of creating a Chrome extension. For it, I need to use Google's Calendar Data API. Here is my manifest.json file:
{
"name": "Test",
"version": "1.0",
"background_page": "background.html",
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["jquery.js", "content_script.js"]
}
],
"permissions": [
"tabs", "http://*/*"
]
}
I've tried adding the following to the js part of the manifest file but that throws an error when loading the extension.
http://www.google.com/jsapi?key=keyhere
I've also tried adding
document.write('<script type="text/javascript" src="http://www.google.com/jsapi?key=keyhere"></script>');
to my background.html file. However, whenever I call
google.load("gdata", "1");
I get an error that says Uncaught ReferenceError: google is not defined. Why is my extension not loading this api when it loads the other ones fine?
You can't include external script into content_scripts.
If you want to inject <script> tag using document.write then you need to mask slash in a closing tag:
document.write('...<\/script>');
You can include your external api js into background page just as usual though:
<script type="text/javascript" src="http://www.google.com/jsapi?key=keyhere"></script>
If you need this api in content scripts then you can send a request to your background page and ask it to do API-dependent stuff there, and then send a result back to your content script.
Thanks for that link, it helped a lot. However, now I've run into another interesting problem.
for (var i = rangeArray.length - 1; i >= 0; i--) {
var myLink = document.createElement('a');
myLink.setAttribute('onclick','helloThere();');
myLink.innerText ="GO";
rangeArray[i].insertNode(myLink);
}
Now I get the error, "helloThere is not defined" even though I placed that function about ten lines above the current function that has the above loop in the same file. Why might this be happening? And if I do:
for (var i = rangeArray.length - 1; i >= 0; i--) {
var myLink = document.createElement('a');
myLink.setAttribute('onclick','chrome.extension.sendRequest({greeting: "hello"}, function(response) { });');
myLink.innerText ="GO";
rangeArray[i].insertNode(myLink);
}
I get Uncaught TypeError: Cannot call method 'sendRequest' of undefined
This is because there is some syntax error in your code. I had same problem. I opened my background.html page in fire fox with fire-bug plug-in enabled. Fire-bug console should me the error, I fixed and it is working now.
