im creating a platform to user automated tests to verify if a widget is functional. I already made the tutorials and the saw the examples but still i can figure out what's happening.
the widget that im trying to test is made with iframes without src attribute and with im trying to find a element inside of that iframe without src attribute.`define(function (require) {
var registerSuite = require('intern!object');
var assert = require('intern/chai!assert');
registerSuite({
name: 'index',
'greeting form': function () {
return this.remote
.get(require.toUrl('localhost:3000'))
.findById('iframeId')
.switchToFrame('iframeId')
.findById('buttonID');
}
});
});`
With this code it happens that the intern runner returns a error saying that it wasn't unable to find the element. But when i try to run the same code on a iframe with a "src" attribute it finds the correct element and doesn't returns any error.
anyone could help ??
In the above code, you should clear the search context before trying to find an element in the iframe, like:
return this.remote
.get(require.toUrl('localhost:3000'))
.findById('iframeId')
.end()
.switchToFrame('iframeId')
.findById('buttonID')
This is assuming the findById call is to wait for the iframe to be added to the page. If you don't need to do that, just leave out the findById('iframeId') call and you should be good.

I am learning about writing custom JavaScript for my Odoo 10 addons.
I've written the following piece of code:
odoo.define('ioio.io', function(require) {
'use strict'
const e = $('div.o_sub_menu_footer')
console.log('--testing--'.repeat(7))
console.log(e)
// the "Powered by Odoo" down the secondary menu
e.remove()
})
The code is well loaded and I can see my testing string in the console.
However when this code is being loaded before the target div, so e empty/not yet filled and thus its content is not removed.
Doing it manually from the console works.
My question is what is the right way to do that? And how to know exactly when the code gets executed?
You can
put your html code before the script tag in your file
use jQuery $(document).ready(...);
Place your script at the bottom of the <body> tag to make sure the DOM renders before trying to manipulate it.
This is an Odoo specific question, so you should use the Odoo standard way, which is via its base JS class. That class contains a ready() method which does exactly what you need.
In your case, to use that function, you need to require the class first. Then you can use ready().
Updating your code, it should look like this:
odoo.define('ioio.io', function(require) {
'use strict'
// require base class
var base = require('web_editor.base');
//use its ready method
base.ready().done(function () {
// put all the code you want to get loaded
// once the DOM is loaded within this block
const e = $('div.o_sub_menu_footer')
console.log('--testing--'.repeat(7))
console.log(e)
// the "Powered by Odoo" down the secondary menu
e.remove()
});
})
While your accepted answer leads to the same outcome, you might want to update it to this one since this is the Odoo way. It's generally advised to work within the Odoo framework as much as possible and customise only if really needed. (Though it can be tough to learn what features Odoo already provides because of its poor documentation.)
I am using protractor. I understand that protractor has Jquery like syntax but I need something that can
create conditions, variables and loops based on DOM elements in some of my testing. I want to be able to use querySelector. Using just promises won't let me do the kind of testing I need to do.
When I run it, it says:
Failed: Cannot read property 'querySelector' of undefined
or
Failed: document is not defined
or
Failed: window is not defined
I've set up a test to test this issue. It runs off a random web page that I was looking at it. It selects the footer using protractor and then attempts it using querySelector. If I enter the querySelector portion in the console, it runs the code correctly. I've also tried variations of querySelector, using window.document; this also works in the browser but not in protractor.
describe("Test", function()
{
it('This is a test to test protractor' , function()
{
browser.waitForAngularEnabled(false);
browser.get("https://facebook.github.io/jest/");
$("#footer").getAttribute("innerHTML").then( function(value)
{
console.log("inside value then");
console.log(value);
});
var queryse = document.querySelector("#footer").innerHTML;
// var queryse = browser.document.querySelector("#footer").innerHTML;
// var queryse = window.document.querySelector("#footer").innerHTML;
console.log('query selector');
console.log(queryse);
});
});
The code you're running in Protractor test case doesn't really run in browser, in fact it's executed in Node.js. You should think of it as an API that will afterwards communicate with the browser through WebDriver. That means that you cannot use browser specific JavaScript API in the code. The $ helper is just there to make the syntax easy and understandable without knowing anything about Selenium. That's why document and window are inaccessible for you. If you want to read more about that: https://github.com/angular/protractor/blob/master/docs/locators.md
#Nhor's answer is mostly correct in terms of the environments and why you cannot use document and window directly. However, for what it's worth, you can definitely find elements in the DOM through executeScript. The only question is, why do you need to do this?
Any locator you can use in the DOM, you can use in Protractor (though the syntax might be different). Here's an example, I used innerHTML because that's what you were trying in your case:
describe('Protractor Demo App', function() {
it('element test', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
var el = browser.executeScript('return document.querySelector("h3").innerHTML');
el.then(function (text) {
console.log(text); // logs "Super Calculator"
});
});
});
Finally, it's important to note that this el is restricted to javascript functions from within that executeScript call. It is not a version of Protractor's ElementFinder, you cannot perform actions like getText() on it (though it is still a Promise, so you need to call .then()). You can do a console log on the el to see what's in that object.
This probably has been answered before but I have tried for 48 hours now to find an answer with now luck. Posting this is a last resort.
So I have this Tetris clone and it works as seen here: http://www.crawfordcomputing.com/portfolio/Jetris.php
But it does not work in this single page angular app:
http://www.crawfordcomputing.com/AkadineWebOS/
I am re-coding the whole site to be a AngularJS single page app. To this end, I load the html via ng-bind-html and the compile directive found here: AngularJS directive in ng-bind-html.
The html string I am binding is exactly: EDIT: tried making canvas a childnode, did not work.<div><canvas id='gamewindow' width='780px' height='560px'></canvas></div>
The necessary scripts are loaded via the function found here: Single page application - load js file dynamically based on partial view
Note: html5jetris.js is actually an object: var jetris = { startgame: function(), ...};
Using firebug, I can see all added elements and the scripts in the DOM. I also am assuming that being a single page already loaded that I cannot use window.onload = jetris.startGame; after the closing ";" of var jetris = {};
1) I tried putting an alert("hello"); as second to last line (just before the call to startGame) and tried stepping through with firebug. It appears that html5jetris.js, while loaded, is not running.
2) I tried to access the canvas by id directly from address bar with javascript:getElementByID("gamewindow").innerHTML = "hello";
no success; this was several seconds after the ng-bind-html executed well past the 1-1.5 seconds it takes angular to load it.
3) if I pre-emptivly load all the js in my index.php, then firefox will step through it. But I only want to load the javascript when needed. This does not fix not being able to access the canvas by id.
4) by it self, Jetris works, just not loaded dynamically by AngularJS.
Note: Jetris does not require jQuery, even though it's there for Angular. It depends on my own utitlty.js (made as part of a javascript class, converted to object: var U = {};) and my own html5canvas.js (again, var canvas = {};) Since these are objects, the variables in them should not bump heads with anything jQuery or Angular.
Any ideas?
here is the directive:
.directive('compile', ['$compile', function ($compile) {
return function(scope, element, attrs) { //taken from Joël (Thank you!) source: https://stackoverflow.com/questions/26594153/angularjs-directive-in-ng-bind-html
scope.$watch(
function(scope) {
// watch the 'compile' expression for changes
return scope.$eval(attrs.compile);
},
function(value) {
// when the 'compile' expression changes
// assign it into the current DOM
element.html(value);
// compile the new DOM and link it to the current
// scope.
// NOTE: we only compile .childNodes so that
// we don't get into infinite loop compiling ourselves
$compile(element.contents())(scope);
}
);
};
}])
Jetris.php:
<?php //Jon Crawford AkadineWebOS pages/jetris.php
//describe window
$window = array();
$window['content'] = "<canvas id='gamewindow' width='780px' height='560px'></canvas>";
$window['title'] = "Jetris";
$window['x'] = 20;
$window['y'] = 250;
$window['id'] = 900;
$window['requireJS'] = array();
$window['requireJS'][0] = "scripts/html5Jetris.js";
$window['requireJS'][1] = "scripts/html5Canvas.js";
$window['requireJS'][2] = "scripts/utilities.js";
echo json_encode($window);
?>
This gets loaded to a div with title bar and exit button that is draggable. My menu system is icon like. My AkadineWebOS looks like a regular desktop. I have an about.php and a welcome.php that work just fine in my div-windows.
Ok so this is a special case I probably did not clarify my question. Here are the steps I used to accomplish my goal.
To load an HTML formated string to the DOM I used a $compile directive by Joël (Thank you!) source: AngularJS directive in ng-bind-html
To load external dependency script files, I used a load script function by Ben Thielker (Thank you!) source: Single page application - load js file dynamically based on partial view
Then I change the onload in my java game Jetris to: var externalJS = { run: function() { window.jetris.startGame(); } };
So that I will not have to re-code my angular app whenever I want to add a new game or other javascript app, this allows my app to check if var externalJS is undefined and if is is defined, it executes externalJS.run();. If the app's div-window is closed, this will effectively restart it when reopened.
Now since everything is loaded using Angular's HTTP module, you have to wait for Angulars promise to finish for everything to be loaded. If I try to run it to soon, I get a blank window and no game. To that end, I use
setTimeout(function() {
if (typeof externalJS != 'undefined'){
externalJS.run();
}},750);
in the HTTP module's successCallback to give it some time.
Here is a link to a working Alpha of the project, with all issues questioned here ironed out. You can drag the windows and icons, open more than one of the same window like a normal desktop unless a oneInstance flag is set like with Jetris, and you can play Jetris! Check it out! AkadineWebOS

Previously I've put working webcam code into my application, but now it's not working when I updated to AngularJS v1.5.0. I am using webcam-directive which was working perfectly with v1.3.0.
Here is my code:
<webcam placeholder="selfiePlaceHolder"
on-stream="onStream(stream)"
on-access-denied="onError(err)" on-streaming="onSuccess(video)">
</webcam>
But now it's giving following error with AngularJS v1.5.0:
Uncaught Error: [$parse:isecdom] Referencing DOM nodes in Angular expressions is disallowed! Expression: onSuccess(video)
http://errors.angularjs.org/1.5.0/$parse/isecdom?p0=onSuccess(video)
I also tried to use a different solution with AngularJS ng-Camera but even its demo page is not working for me.
Note: I know the issue is that we can't access the DOM from the newer version of AngularJS, but the same code works with the older version. I need to know how to pass the "Video" DOM object to the controller.
I've found the solution to the problem. Two things need to be done:
First In HTML:
<webcam channel="channel"
on-streaming="onSuccess()"
on-error="onError(err)"
on-stream="onStream(stream)"></webcam>
Secondly, in the controller, you can access the DOM video with the following code:
$scope.onSuccess = function () {
// The video element contains the captured camera data
_video = $scope.channel.video;
$scope.$apply(function() {
$scope.patOpts.w = _video.width;
$scope.patOpts.h = _video.height;
//$scope.showDemos = true;
});
};
Here is a working example.
It is a potential error generally occurs when an expression tries to access a DOM node since it is restricted accessing to DOM nodes via expressions by AngularJS because it might cause to execute arbitrary Javascript code.
The $parse:isecdom error is related to an invoke to a function by event handler when an event handler which returns a DOM node, like below:
<button ng-click="myFunction()">Click</button>
$scope.myFunction = function() {
return DOM;
}
To fix this issue, avoid access to DOM nodes and avoid returning DOM nodes from event handlers. (Reference: https://docs.angularjs.org/error/$parse/isecdom)
Adding an explicit return might solve this issue as detailed here: CoffeeScript - Referencing DOM nodes in Angular expressions is disallowed
I was able to get webcam-directive working using the channel suggestion from the comment above, based on the example on the github page.
function MyController($scope) {
$scope.myChannel = {
// the fields below are all optional
videoHeight: 800,
videoWidth: 600,
video: null // Will reference the video element on success
};
}
In the onSuccess(on-streaming attr) and onStream(on-stream attr) callback the video property of myChannel was filled in with the video DOM element (and then it would obviously be available to everything else in the controller too). According to the comment in the example code though, you should wait to access it at least until onSuccess. Here is a working example
I am using webdriverjs for some testing and I am loving it so far. I am just running into an issue where I cant seem to run more broad tests. I am curious if there is any way to see if a page has specific content, but not have to pass it a particular css-selector?
I.e. I have a webpage with a bunch of text all over the place, and I specifically want to run a test to see if my page has the string "Hello World!" somewhere on the page. It doesnt matter where the string is, just that it is there.
If this isn't possible with webdriverjs, is there some other way to run this kind of test?
It is possible with webdriverjs. There is no hasContent method by default, but it's easy to create one on your own using the getText() method. getText() obtains the visible text of a given element and its subelements. So to get the whole text of a webpage you can just call in on the <html> element. Like this:
var selenium = require('selenium-webdriver');
var By = selenium.By;
var driver = new selenium.Builder().withCapabilities(selenium.Capabilities.chrome()).build();
function hasContent(content) {
driver.findElement(By.tagName('html')).getText().then(function(entireVisibleText) {
if (entireVisibleText.indexOf(content) > - 1) {
// text found
}
else {
// text not found
}
});
}
