I trying add in animation slide right to left when modal page show, but when I adding will get error, isn't can add animation when open modal page?
exports.onModalClick = function(args){
var btn = args.object;
page.showModal("views/abc/Modal/Modal", "abc", function (List) {
if(List.length != 0){
}
}, false).animation({ translate: { x: 0, y: 0 }, opacity: 1 });
};
I would like to point out a few things.
The method for animating a view is
public animate(options: animation.AnimationDefinition): Promise<void>;
and it is an instance function of the View class. Thus your scenario will not work, since the showModal method does not return an instance of the class View. More information about it could be found in the documentation and in the NativeScript GitHub repository.
In order to attach several animations you will have to chain them and not include them in one object. You can read more about this in the Animation article in the documentation.
I hope this will give you some directions of how to use the animation in NativeScript.

I need to add back navigation on swipe. I can do that fairly easily by just adding a swipe listener to the page view and calling goBack. But I really would like the animation that goes with it (in Instagram or FB) where as soon as you start dragging your thumb, the page translates to the right and the previous page starts to translate into view. And then once you get to a certain point it actually performs the navigation.
I tried animating the page, as well as the frame to the right figuring since the view isn't being destroyed it might work. But it doesn't display the page Im navigating back to.
Looking for help on how to accomplish this!
I guess you might have come across the other SO thread answering this question natively.
All you have to do is modify the default gesture recogniser on iOS frame.
export function onNavigatedFrom(args: EventData) {
console.log("Adding gesture...");
const frame = (<Page>args.object).frame;
if (frame.ios && !(<any>frame)._gestureRecognizer) {
const controller = frame.ios.controller;
const popGestureRecognizer = controller.interactivePopGestureRecognizer;
const targets = popGestureRecognizer.valueForKey("targets");
if (targets) {
let gestureRecognizer = UIPanGestureRecognizer.alloc().init();
gestureRecognizer.setValueForKey(targets, "targets");
frame.nativeView.addGestureRecognizer(gestureRecognizer);
(<any>frame)._gestureRecognizer = gestureRecognizer;
}
}
}
export function onNavigatedTo(args: EventData) {
console.log("Back to root page, removing gesture...");
const frame = (<Page>args.object).frame;
if (frame.ios && (<any>frame)._gestureRecognizer) {
frame.nativeView.removeGestureRecognizer((<any>frame)._gestureRecognizer);
(<any>frame)._gestureRecognizer = null;
}
}
Playground Sample
I extend a Control to create a new custom control in UI5 and this control renders a tree as UL items nicely. Now I need to implement a collapse/expand within that tree. Hence my renderer writes a tag like
<a class="json-toggle" onclick="_ontoggle"></a>
and within that _ontoggle function I will handle the collapse/expand logic.
No matter where I place the _ontoggle function in the control, I get the error "Uncaught ReferenceError: _ontoggle is not defined"
I am missing something obvious but I can't find what it is.
At the moment I have placed a function inside the
return Control.extend("mycontrol",
{_onToggle: function(event) {},
...
Please note that this event is not one the control should expose as new event. It is purely for the internals of how the control reacts to a click event.
I read things about bind and the such but nothing that made sense for this use case.
Took me a few days to crack that, hence would like to provide you with a few pointers.
There are obviously many ways to do that, but I wanted to make that as standard as possible.
The best suggestion I found was to use the ui5 Dialog control as sample. It consists of internal buttons and hence is similar to my requirement: Render something that does something on click.
https://github.com/SAP/openui5/blob/master/src/sap.ui.commons/src/sap/ui/commons/Dialog.js
In short, the solution is
1) The
<a class="json-toggle" href></a>
should not have an onclick. Neither in the tag nor by adding such via jQuery.
2) The control's javascript code should look like:
sap.ui.define(
[ 'sap/ui/core/Control' ],
function(Control) {
var control = Control.extend(
"com.controlname",
{
metadata : {
...
},
renderer : function(oRm, oControl) {
...
},
init : function() {
var libraryPath = jQuery.sap.getModulePath("mylib");
jQuery.sap.includeStyleSheet(libraryPath + "/MyControl.css");
},
onAfterRendering : function(arguments) {
if (sap.ui.core.Control.prototype.onAfterRendering) {
sap.ui.core.Control.prototype.onAfterRendering.apply(this, arguments);
}
},
});
control.prototype.onclick = function (oEvent) {
var target = oEvent.target;
return false;
};
return control;
});
Nothing in the init(), nothing in the onAfterRendering(), renderer() outputs the html. So far there is nothing special.
The only thing related with the onClick is the control.prototype.onclick. The variable "target" is the html tag that was clicked.
I have the new invisible recaptcha working fine, but it puts the badge in bottom left or right corner. You can override this with "data-badge='inline'" and that pulls it into the form. Google is extremely vague on how to actually move it. You cannot hide it as google will not validate your form anymore. Soo...
THE ISSUE is I cannot seem to move it anywhere else on the page. I want to move it to the bottom of the page inside a div I created. Has anyone successfully done this? I tried appendTo but that does not work.
$('.grecaptcha-badge').appendTo("#g-badge-newlocation");
Any help would be great!!!
Thank you.
If you want to comply with Google Terms, then you can use a timer to detect the badge and then move it down at the bottom. You have to set the badge property to inline. jQuery appendTo worked for me:
Recaptcha code
var onSubmit = function(token) {
console.log('success!');
};
var onloadCallback = function() {
grecaptcha.render('submit', {
'sitekey' : '<your_site_key>',
'callback' : onSubmit,
'badge': 'inline'
});
};
The code to setup a timer to check and move grecaptcha-badge element
jQuery(function($) {
var checkTimer = setInterval(function() {
if($('.grecaptcha-badge').length > 0) {
$('.grecaptcha-badge').appendTo("#g-badge-newlocation");
clearInterval(checkTimer);
}
}, 50);
});
Please check my live example here (http://zikro.gr/dbg/google/recaptcha/). You can see that the badge goes at the bottom inside #g-badge-newlocation element and that it works because when you hit submit, recaptcha triggers the callback function which logs the word "success~".
Anyone got a tip how to add a View over the current view (modal)? I'm creating an app with a video recorder, and the video screen is presented modally on the screen. I want some text to show up above the video modal, and I think I've tried any approach I can think of atm.
Currently im stuck with something like:
var topMost = frameModule.topmost();
var View = new ViewModule.View(questionHolder);
topMost.currentPage._addView(View, 0);
But with no success. questionHolder is a view I fetch with
currentpage.getViewById
Edit:
From the answer of #davecoffin where I understood you could not mix native views and nativescripts views, I was able to solve this in my case by accessing the native view directly and adding a subview to it. In my case:
var sharedApplication = utils.ios.getter(UIApplication, UIApplication.sharedApplication);
var overlay = UIView.alloc().initWithFrame({
origin : {
x: 0,
y: 44,
},
size: {
height: 100,
width: platform.screen.mainScreen.widthPixels
}
});
overlay.backgroundColor = UIColor.blackColor;
overlay.alpha = .6;
sharedApplication.keyWindow.rootViewController.presentedViewController.cameraOverlayView = overlay;
You can directly create and use modal pages as described in this article.
If I am understanding your approach correctly...
You cant add Nativescript views on top of native views.
Check out this forum question: https://discourse.nativescript.org/t/appending-nativescript-views-to-a-native-ui-view/1412
Basically once you have appended a native view (not a nativescript layout or ui view), then every view you append after that must be a native view. For iOS you use addSubview, not sure about android atm.
I'm using Hammer.js to look for horizontal pan gestures, I've devised a simple function to clicks a button when panned left or right. It works okay, except the vertical scroll doesn't do anything on a touch device, or it's really glitchy and weird.
Here's the function:
var panelSliderPan = function() {
// Pan options
myOptions = {
// possible option
};
var myElement = document.querySelector('.scroll__inner'),
mc = new Hammer.Manager(myElement);
mc.add(new Hammer.Pan(myOptions));
// Pan control
var panIt = function(e) {
// I'm checking the direction here, my common sense says it shouldn't
// affect the vertical gestures, but it blocks them somehow
// 2 means it's left pan
if (e.direction === 2) {
$('.controls__btn--next').click();
// 4 == right
} else if (e.direction === 4) {
$('.controls__btn--prev').click();
}
};
// Call it
mc.on("panstart", function(e) {
panIt(e);
});
};
I've tried to add a horizontal direction to the recognizer but it didn't really help (not sure if I did it even right):
mc = new Hammer.Manager(myElement, {
recognizers: [
[Hammer.Pan,{ direction: Hammer.DIRECTION_HORIZONTAL }],
]
});
Thanks!
Try setting the touch-action property to auto.
mc = new Hammer.Manager(myElement, {
touchAction: 'auto',
recognizers: [
[Hammer.Pan,{ direction: Hammer.DIRECTION_HORIZONTAL }],
]
});
From the hammer.js docs:
When you set the touchAction to auto it doesnt prevent any defaults, and Hammer would probably break. You have to call preventDefault manually to fix this. You should only use this if you know what you're doing.
User patforna is correct. You need to adjust the touch-action property. This will fix scrolling not working when you have hammer bound on a big element in mobile.
You create a Hammer instance like so
var h = new Hammer(options.contentEl, {
touchAction : 'auto'
});
I was working on a pull to refresh feature, so I need the pan event.
Add the recognizers.
h.get( 'pan' ).set({
direction : Hammer.DIRECTION_VERTICAL,
});
h.on('panstart pandown panup panend', eventHandler);
Inside the eventhandler, you'd look at the event that was triggered and manually call on event.preventDefault() when you require it. This is applicable for hammer 2.0.6.
For anyone who's looking the pull to refresh code was taken from - https://github.com/apeatling/web-pull-to-refresh
My problem was that vertical scroll was toggling a sidebar that was supposed to show/hide on horizontal pan/swipe. After looking at the event details, I realized that Hammer probably triggers panleft and panright event based on X delta and doesn't consider Y delta, so my quick solution was to check the pan direction in my handler:
this.$data.$hammer.on('panleft', (e) => {
if (Math.abs(e.deltaY) > Math.abs(e.deltaX)) {
return;
}
this.isVisible = true;
});
I was stuck on this for several days. Hope this will fix your problem.
mc = new Hammer(myElement, {
inputClass: Hammer.SUPPORT_POINTER_EVENTS ? Hammer.PointerEventInput : Hammer.TouchInput,
touchAction: 'auto',
});
When the relevant gesture is triggered, we applied a css class to the element, that would set the touch-action to none.
mc.on('panmove panstart', event => {
mc.addClass('is-dragging');
}
);
.is-dragging {
touch-action: none !important;
}
Hammer 2.x does not support vertical swipe/pan. Documentation says:
Notes:
When calling Hammer() to create a simple instance, the pan and swipe recognizers are configured to only detect horizontal gestures
You can however use older 1.1.x version, which supports vertical gestures
——
Clarification: this refers to a ‘simple instance’ which is when you don’t pass in any recognizer configuration as the second parameter. In other words these are the defaults but can (and usually should) be overridden.
