will return a NodeList which is a HTMLCollection. So if there is no element with given class, you will still get an empty Node List.
However, when you try to access oth element, since its an empty list, you get undefined
(as rightly suggested by kaiido). Hence you get false
.
Following is a sample representation:

How can you launch Browser Console for firefox:
1. open firefox (and give any URL )
2. Press Ctrl+Shift+J (or Cmd+Shift+J on a Mac)
Link : https://developer.mozilla.org/en-US/docs/Tools/Browser_Console
else if (browser.Equals(Constant.Firefox))
{
var profileManager = new FirefoxProfileManager();
FirefoxProfile profile = profileManager.GetProfile("ConsoleLogs");
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(DrivePath);
service.FirefoxBinaryPath = DrivePath;
profile.SetPreference("security.sandbox.content.level", 5);
profile.SetPreference("dom.webnotifications.enabled", false);
profile.AcceptUntrustedCertificates = true;
FirefoxOptions options = new FirefoxOptions();
options.AcceptInsecureCertificates = true;
options.Profile = profile;
options.SetPreference("browser.popups.showPopupBlocker", false);
driver = new FirefoxDriver(service.FirefoxBinaryPath, options, TimeSpan.FromSeconds(100));
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
}

QUESTION
QScriptEngine eng;
QScriptEngineDebugger debugger;
debugger.attachTo(&eng);
QScriptValue consoleObj = eng.newQObject(this);
eng.globalObject().setProperty("asd", consoleObj);
QScriptValue handler= eng.evaluate("(function(text) { asd.log('text was changed to '+text); })");
QLineEdit *edit = new QLineEdit(this);
qScriptConnect(edit, SIGNAL(textChanged(QString)), QScriptValue(), handler);
edit->show();
...ANSWER
Answered 2018-May-26 at 01:54A variable created in a method that is not created in the heap is deleted when it finishes executing the method, in your case the QScriptEngine
is created in the constructor reason why it is eliminated, and all the script depends on it. The solution is simple, make the QScriptEngine
member of the class:
mainwindow.h
QUESTION
I want to use jsconsole, I open website, write ':listen' in the console and nothing happens. I was not able to find instruction. How should I use it to debug my application in Lumia phone?
...ANSWER
Answered 2017-Dec-02 at 17:33Bad news, remote debugging has been depreciated as shown here: https://github.com/remy/jsconsole/issues/101
Edit: If you are working with node there is nodejs --inspect https://nodejs.org/en/docs/inspector/ if that is help, there is also is an emulation tool in IE11 for debugging websites on window phone if you are on window 8.1+ https://msdn.microsoft.com/library/dn255001%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
QUESTION
In Polymer 2 docs, they show using the constructor to set this.owner = "daniel" and then later they show how to set properties using static get properties().
In JSConsole, I can use myelement.owner and myelement.prop1, and if I dir(myelement) I can see both owner and prop1 there... so what's the difference?
...ANSWER
Answered 2017-Jul-31 at 19:06Well, As regards to functionality, both achieve the same.
- Initialize a class variable
The timeline favors the constructor initialized variable really.
However, since you initialize owner in the CTOR, you can not fetch it via myElement.properties
.
the advantage of using the static method may be that, you need not create an element from class
myElement
to fetch any property you defined inside the static method.
Try logging
myElement.properties
- and see that you can not find owner listed. you will however find prop1 there.
However, for you to get the value of owner, you essentially need to instantiate the class myElement
or connect an element to the DOM
Try logging
myElement.owner
- this should return undefinedTry logging
new myElement().owner
- this should fetch daniel
QUESTION
As good practice, I usually scan already asked questions to find a solution to my issues but I have exhausted all search on this one.
In a nutshell:
I have developed my website from scratch and then converted to a wordpress theme. Everything works fine on desktop, resized browser shows website responds and adjusts style to be mobile friendly (have also tested on mobile devices and so there's nothing wrong with the style). There are no errors that I could find on a console, not on desktop nor on mobile.
However none of the javascript functions work on the following devices I have and tested my website on:
- Samsung Galaxy Note 3: native browser
- Ipad (iOS 8.3): tested on browsers: Safari and Atomic Lite
Funnily enough, on my Samsung Galaxy, I downloaded a couple of other browsers just to check:
- Adblock Browser
- DebugBrowser (this has a javascript console and I checked for errors: there are none).
I have uploaded my website for testing and you can see it at: http://efcotest.web-merchant.co.nz/
Yes, I know having a slideshow on mobile view isn't great practice, but I intend to remove it, just that when I started testing for basic functionality (mainly the site menu) I discovered that javascript isn't working at all as per above brief.
Any help people?
EDIT: Alright so I remotely debugged with jsconsole.com and found that my javascript functions are called with unresolved reference errors. I've checked this both on my Galaxy Note's native browser and on the Ipad. The same reference errors.
This was my suspicion, and now here's confirmation that my script file isn't loading on these specific devices ad browsers.
I really can use some help here as I am absolutely at a loss to understand why the script doesn't load, I have properly registered and enqueued the script in functions.php as per wordpress requirements so I can't see what the problem is. Help anyone?
Note: I should add that they are as per jsconsole, for example ->
Uncaught ReferenceError: ShowMobileMenu is not defined
Hi Esha, thanks for your response. Here is my functions.php, as you'll see I am enqueuing my script:
...ANSWER
Answered 2017-May-21 at 10:17The page source of link you shared above has below code. It calls for function ShowMobileMenu. But there is no script file which has this function defined.This is the reason you have referenced error.
In fact I had reference error on desktop chrome browser. Please check if you are enqueuing your JS file in which these functions are defined. Your theme is enqueues only CSS file no JS file.
QUESTION
API results render to desktop but not to my iPhone. So I have a simple rest API that I'm making the calls from a ReactJS front end. I'm using axios after having a LOT of troubles with superagent. I'm not getting any errors in any browser console, desktop or mobile(been using jsconsole to debug my iphone 5). Yet on my Python Tornado back end it's throwing a few errors for both desktop and mobile:
1st:
tornado.application:Uncaught exception GET
2nd:
ERROR:tornado.general:Cannot send error response after headers written ERROR:tornado.general:Failed to flush partial response
3rd:
During handling of the above exception, another exception occurred:
and this can be found as the error happening in my Python env files
TypeError: 'str' object is not callable
none of this crashes the script/app... Here's my ReactJS/Javascript using axios:
...ANSWER
Answered 2017-Mar-03 at 02:10I'm marking this as solved as there aren't any errors to work off of so it's just down to debugging whatever is causing the issue of not rendering to mobile.
