In a React component, I tried rendering
<a id="help" onClick={this.handleHelp}>{_('Help')}</a>
and I put
this.handleHelp = this.handleHelp.bind(this);
in the constructor. So I want to bind that click to our legacy javascript Help library.
I tried
handleHelp(e) {
e.preventDefault();
window.Help.init('some_value');
}
When clicked, absolutely nothing happens, including no messages nor errors in developer console. The Help jquery script is loaded at the time. On init, that binds $("#help").on("click", showHelp); so I was hoping I could somehow trigger that click in the handleHelp handler, but I've not been able to figure out how.
UPDATE: Thanks to responders, I figured out to just add a call to the window.Help.showHelp() function into my handleHelp, after window.Help.init(). (Obvious, in hindsight.)

I have a protractor test looking for a record in my infinite scroller component like this.
searchPage.searchEntitlement('search criteria');
var myHiddenElementInScroller = element(by.repeater('result in ctrl.results track by $index').row(12));
browser.driver.executeScript(function () { arguments[0].scrollIntoView(); }, myHiddenElementInScroller .getWebElement());
myHiddenElementInScroller.click();
This is supposed to scroll to the element and click it. Instead its throwing me element not visible error.
Has anyone come across this situation? Any help greatly appreciated.
You might need to explicitly wait for the scrolling into view actually happen:
browser.driver.executeScript("arguments[0].scrollIntoView()", myHiddenElementInScroller.getWebElement()).then(function () {
myHiddenElementInScroller.click();
});
Or, with browser.actions():
browser.actions().mouseMove(myHiddenElementInScroller).click().perform();
In few scenarios the element which we are looking for will be covered with some other element from DOM.when protractor tries to click it,the click will be received by the element that covers the actual element. So in such situation you need to use native javascript click event. Look at the below code.
browser.executeScript("arguments[0].click()", myHiddenElementInScroller.getWebElement())
The above code will send a click event directly to the mentioned webElement even if it is visible or not.
NOTE: this is not the recommended way for clicking an element. but you can you this in scenarios where you have no other workaround to achieve the click event.
Thanks for all the responses. I was able to resolve this issue by using element(by.CssContainingText(cssSelector, searchText)) locator.
I don't know if i titled my question correctly but here is what i want to achieve and what i have so far (simplified as much as possible):
What I have so far:
For each Visitor I create a "Visitor" Object:
{
name:"Bob",
mouseX:"31", // The mouseposition is constantly updated
mouseY:"400",
messages:[
{text:"Message Text",prop:"other property"},
{text:"Another Message"}
]
}
After that I bind the Object to the scope:
$scope.helpers({
visitor: () => Visitors.findOne({"_id":id})
});
The Messages are shown inside a ng-repeat over the visitor.messages model:
<div ng-repeat="msg in visitor.messages">
<span class="text {{msg.class}}"> {{msg.text}} </span>
</div>
Another Visitor can send a new Message with:
Visitors.update(
{_id: visitor._id},
{$push: {messages: {"text":"New Message"}}}
);
What I want to do
When Bob receives a new message i want to trigger the function newMessageArrived() and to animate the new Message in.
The Problem and what i tried so far
First i tried to use angular:angular-animate package and animate new messages with css-classes but ng-enter triggered for alle messages each time visitor.mouseX was updated and even if nothing other than the messages in the Visitors-Object where pushed still ng-enter triggered for all messages instead only for the new ones.
Thats ok because i guess that the whole DOM is rebuild when the Visitor-Object changes. Now i tried to simply watch the messages prop of the Visitors-Object like:
scope.$watch("visitor.messages", function ( newValue, oldValue ) {
newMessageArrived()
});
Again newMessageArrived() is triggering with each update to the Visitors-Object. Of course i could catch this stupidly with something like checking the length of the messages array but in my understanding even using $watch without this is wrong already.
The Question
So what is the Angular-Meteor way of reacting on changes in a property of a MongoDB Cursor (Object)?
Please consider my examples are extremly simplified to focus on my problem but also i am new to Meteor and not even very experienced in Angular. Also this is for a "proof of concept" project and not for any commercial or professional context, so security, performance and maintainability are not as crucial as usual.
Thanks for your time and hopefully for any help
I found a solution I guess.
Uringo from Angular-Meteor explained in another similar question on Github:
#gooor this is how Meteor's autorun works. it executes on every change
on any reactive thing inside it and a Meteor cursor is a reactive
object. If you want to re-run something only when field is changing
you can use Angular's $watch:
$scope.$watch('field', function(){ console.log('calling');
this.foos = Foos.find({field: this.field}); });
In my particular case I needed to add true as the third parameter to the $watch function. Therefore newMessageArrived() is only called when the property messages is changed.
So my initial concerns where wrong but when someone has a better, more meteorish solution i would appreciate.
As my question asks, I want to know if that is possible. Why I want this? I am required to keep the link when the request fails so I use states in my bootstrap template instead of templates for the error pages. Now I need to catch everything that isn't registered and I need to tell my main controller to change the state if the route is not found. I checked the documentation, of course but it hasn't enlightened me so please help me out here if you can.
$httpProvider.otherwise(function () {
// code here
});
Is something like this possible?
I want to be able to set a keyboard shortcuts for buttons in an application I'm building. I'd like to be able to pass in the keyboard button code as a parameter to make it configurable. Here's what I have so far using the documentation before I got stuck. HTML:
<div ng-controller="BtnCtrl">
<button class="primary-btn" type="submit" ng-keypress="press($event, '12')">Button</button>
</div>
JavaScript:
angular.module('App')
.controller('BtnCtrl', function ($scope) {
$scope.press = function($event, hotKeyRef) {
if ($event.keyCode==hotKeyRef) {
//need some code here to trigger the button press
}
}
});
So using my approach, I'm unsure of a) how to trigger the button press from inside the function and b) whether this is the correct way of passing in the keyCode data.
I might also be taking completely the wrong approach, so any other guidance would be appreciated.
Thanks
For the question a).
The main uses of a < button > html element is to fire an event on a click.
So if you want to use a keypress, why use this element ? I don't really see what you want to achieve. that seems controversal.
for b) :
By default, ng-keypress is intended to be used in an input element.
Otherwise, it seems that some posts, where I inquired, manage to make it work out.
You can see what it can look like, for example on this post (Is it possible to listen for arrow keyspress using ng-keypress?)
in which the person trying to setup the konami code.
Moreover, it seems that you can have trouble depending on which browser (Chrome, Firefox, Safari, IE) you uses. Be careful.
I hope this could help you.
hi there is an excellent plugin for your scenario u can check the below link

What is AngularJS way to create global keyboard shortcuts?
I'm converting a page in a mvc application with a lot of inline jquery javascript to angular using typescript.
The first calls works fine but I have a problem: based on a selection in a dropdown, the event updates several controls in the view, make a few ajax calls and finally update the view with the data from the calls.
Seems the conversion is working fine, but at the end of the call the page isn't updated.
I tried to remove all the old jquery code to avoid problems.
batarang and java console reports no errors.
the final ajax call is done and the result shown in a debug.
All seems to work fine, but the page isn't updated.
How can I find the problem?
thanks
Without seeing any code, it's difficult to answer but if you bind an event to an element and want to update something in the callback, you will have to use $apply
scope.$apply(function () {
// your code
});
$apply will trigger a $digest cycle, and should be used when you want to update something while being outside angular's context.
Most likely you are not handling your asynchronous calls correctly. It's impossible to tell from your question but it is a very common mistake with symptoms as you describe.
Make sure you are updating your model within the .then() method of a promise returned from an $http request. For example
someFnDoingHttpRequest().then(function(data){
// updated the model with the data
})
Also (another common mistake) make sure someFnDoingHttpRequest() returns a promise.
If you want to "find the problem" then you can use the following option.
Go to Internet Explorer (10 or 11).
Select "Internet Options" from the settings menu.
Go to the "Advanced" tab (the last tab)
Settings are listed and select "Display a notification about every script error"
Deselect the "Disable Script debugging (Internet Explorer)" and "Disable script debugging (Other)"
Run the program again, you will get notification about the real issue that happens while displaying actual result.
