I am experimenting with using NativeScript to speed up the process of porting an existing Android app to iOS. The app in question uses a great deal of SVG manipulation in a Cordova webview. To keep things simple I want to port all of my existing Webview side code - in essence the entire existing Cordova www folder and its contents - over to the new NativeScript app. The WebView talks to a custom Cordova plugin which I use to talk with my servers to do such things as get new SVGs to show, keep track of user actions etc.
If I an get through these teething issues I am considering using this component to implement bi-direction communications between by current webview JS code and the, new, NativeScript backend that will replace my current Cordova plugin. Someone here is bound to tell me that I don't need to do that... . However, doing so would mean throwing out the baby with the bathwater and rewriting all of my current Webview ES6/JS/CSS code.
This is pretty much Day 1 for me with NativeScript and I have run into a few issues.
I find that I cannot get rid of the ActionBar even though I have followed the instructions here and set the action bar to hidden.
I can use the following markup in home.component.html
to show external web content. However, what I want to really do is to show the local HTML file that is in the www folder in the following folder hierarchy
app
|
____home
|
____www
|
______ index.html
|
______css
|
______ tpl
|
.....
However, when I use the markup
<Page actionBarHidden="true" >
<WebView src="~/www/index.html"></WebView>
</Page>
I am shown the error message
The webpage at file:///data/data/com.example.myapp/files/app/www/index.html is not available.
I'd be most grateful to anyone who might be able to tell me what I am doing wrong here - and also, how I can get rid of that action bar which is currently showing the app title.
About using local HTML file
Is your local HTML file recognized by Webpack (which is enabled by default in NativeScript)? Try to explicitly add the local HTML file to your webpack.config.js file. This way Webpack will "know" that it will have to bundle this file as well.
new CopyWebpackPlugin([
{ from: { glob: "<path-to-your-custom-file-here>/index.html" } }, // HERE
{ from: { glob: "fonts/**" } },
{ from: { glob: "**/*.jpg" } },
{ from: { glob: "**/*.png" } },
]

About hiding the ActionBar
NativeScript Core only: Try hiding the action bar directly for the frame that holds the page. See the related documentation here
NativeScript Angular: The page-router-outlet will have an action bar by default (you can hide it by using the Page DI as done here). Otherwise, you could create a router-outlet (instead of page-router-outlet). The router-outler won't have the mobile-specific ActionBar.
I want to get a value (content) from the CSS of a pseudo element (::before) while inside a test made using WDIO and Appium for an Android hybrid app because the designer has stored the current responsive-design state there. So my tests would know which layout (elements) to expect.
Multiple answers to related questions (1; 2; 3) indicated that using .getComputedStyle() might be the only solution. But this does not seem to work in my tests. The error is window is not defined for window.getComputedStyle(...) or document is not defined if I use document.defaultView.getComputedStyle(...). Also selectors themselves can't address pseudo-elements it seems.
Example of one of my many attempts:
document.defaultView.getComputedStyle($('body'),'::before').getPropertyValue('content')
Question: Do I need to somehow import window or document to my test? Is there some other way to get window or document from inside the test?
Ultimately: how can I get the content value of ::before of the <body> of a hybrid Android app?
Thanks to Jeremy Schneider (#YmerejRedienhcs) & Erwin Heitzman (#erwinheitzman) for help!
One solution is to use the execute function:
let contentMode = browser.execute(() => {
let style = document.defaultView.getComputedStyle(document.querySelector('body'),'::before');
return style.getPropertyValue('content')
});
Alternatively maybe something could also be done with getHTML.
I use this library in my ionic project (Cross platform mobile application), And I try to set minLength : 1 but it takes default value (i.e. 3). How can i achieve this?
Set the min-length="1" property to the <auto-complete> instead of <tags-input> to get suggestions for every character.
like this:
<tags-input ng-model="vm.tags">
<auto-complete source="vm.loadTags($query)"
min-length="1"
highlightMatchedText="true">
</auto-complete>
</tags-input>
Even I spent a few hours figuring out how to do it, it later flashed me when I read the documentation of autoComplete again.

I'm attempting to use a JSON object living in a data.json file to be the dataset for a quick prototype I'm working on. This lives in a my_project/www/data/ directory. I have an Angular service that goes and grabs the data within this file using $http, does some stuff to it, and then it's used throughout my app.
I'm using Cordova and Ionic. When using ionic serve on my computer, everything looks perfect in the browser. However, when using ionic view (http://view.ionic.io/) and opening the app on my iPad, I see a:
{"data":null,"status":0,"config":{"method":"GET","transformRequest":[null],"transformResponse":[null],"url":"../data/items.json","headers":{"Accept":"application/json,test/plain,*/*}},"statusText":""}
for a response. I would think that if it were a relative URL issue, that it would also not work in the browser, but that is not the case.
Here's what I'm doing:
config.xml has this line:
<access origin="*" subdomains="true"/>
My service that preforms the simple request is doing:
return $http.get("../data/data.json").then(function (response) {
return response.data;
});
And finally, in my controller, I ask for the service to preform the request:
myService.goGetData().then(onComplete, onError);
In my browser, onComplete() is invoked and on the iPad, onError() is invoked.
Any guidance?
On your local developer machine you're actually running a webserver when you run ionic serve. So a path like ../../data.json will work because it is totally valid in the context of the webserver that has complete filesystem access.
If, however, you try to do the same thing on your device, you're probably going to run into an issue because the device has security policies in place that don't allow ajax to traverse up outside of the root. It is not a dynamic webserver so it can't load files up the tree. Instead you'd use something like the cordova file plugin to grab the file contents from the filesystem. If you prefer, you can use ngCordova to make interacting with the plugin a bit less painful.
I am 99% sure this is what is happening but you can test my theory by pointing your $http call to some dummy .json data hosted on a publicly available server to see if it works. Here is some dummy json data.
Just gonna leave this here because I had the same problem as the original question author. Simply removing any starting slashes from the json file path in the $http.get function solved this problem for me, now loading the json data works both in the browser emulator and on my android device. The root of the $http call url seems to always be the index.html folder no matter where your controller or service is located. So use a path relative from that folder and it should work. like $http.get("data/data.json")
So this is an example json file. save it as data.json
[
{
"Name" : "Sabba",
"City" : "London",
"Country" : "UK"
},
{
"Name" : "Tom",
"City" : "NY",
"Country" : "USA"
}
]
And this this is what a example controller looks like
var app = angular.module('myApp', ['ionic']);
app.controller('ExhibitionTabCtrl', ['$scope', '$http', function($scope,$http) {
$http.get("your/path/from/index/data.json")
.success(function (response)
{
$scope.names = response;
});
}]);
Then in your template make sure you are you are referencing your controller.
<ion-content class="padding" ng-controller="ExhibitionTabCtrl">
You should then be able to use the a expression to get the data
{{ names }}
Hope this helps :)
I was also looking for this and found this question, since there is no real answer to the problem I kept my search on the Internet and found this answer at the Ionic Forum from ozexpert:
var url = "";
if(ionic.Platform.isAndroid()){
url = "/android_asset/www/";
}
I've used it to load a 3D model and its textures.
update: ionic 2 beta (version date 10 Aug 2016)
You must add prefix to local url like this: prefix + 'your/local/resource'.
prefix by platform:
ios = '../www/'
android = '../www/'
browser = ''
we can create an urlResolver provider to do this job.
notice: only change url in *.ts code to access local resource, don's do this with remote url or in html code.
Have fun and good luck with beta version.
An Starter Ioner
It is possible to access local resources using $http.get.
If the json file is located in www/js/data.json. You can access using
js/data.json
Do not use ../js/data.json. Using that only works in the local browser. Use js/data.json will work on both local browser and iOS device for Cordova.
I am encountering a very stragne bug, i am trying to call javascript from AIR like this
this.webView.loadURL( 'javascript:alert(5)' ); -- This works
this.webView.loadURL( 'javascript:alert("hello there")' ); -- This is not working
I am not able to pass strings, in any function. I am not sure why this is happening and it is driving me insane. It works correctly in Android though.
Any help would be greatly appreciated.
Thanks
EDIT: after spending sometime tweaking it seems to be the space. alert("hello") works fine alert("hello there") doesnot.
Ok I think I found it.
You cannot pass whitespaces. You can in Android and Desktop - but no, the glorious iOs refuses to digest such an advanced entity.
So you must encode your whitespaces in strings and make sure that there will be no stray whitespace in your functiond declration
for example
this.webView.loadURL("javascript:test('hey__there')"); //will work
while
this.webView.loadURL("javascript: test('hey__there')"); //this won't
this.webView.loadURL("javascript:test( 'hey__there' )"); //this won't
Good luck
