I have a NativeScript 8.1 JavaScript project that uses the tabs template, so that the app-root.xml file looks like this:
<TabView tabTextFontSize="16" androidOffscreenTabLimit="0" androidTabsPosition="bottom"
id="tabview" class="ns-light" loaded="onLoaded" >
<TabViewItem title="Riders" iconSource="res://biking_solid" >
<Frame id="main" defaultPage="views/main-page" />
</TabViewItem>
<TabViewItem title="Volunteers" iconSource="res://hands_helping_solid" >
<Frame id="vol" defaultPage="views/volunteers-page" />
</TabViewItem>
<TabViewItem title="Director" iconSource="res://user_ninja_solid" >
<Frame id="director" defaultPage="views/director-page" />
</TabViewItem>
</TabView>
The catch here is that the third tab needs to be conditional and only visible if the user is authorized. I've tried pop'ing the TabView's item's array. I've tried creating a new TabViewItem and pushing it onto the items array. I've tried using the visibility property, and none of these work.
I'll know at startup time whether the third tab should be displayed, so handling this in app-root.js is fine. I'm OK with creating all of the tabs dynamically but I can't get that to work either. I could live with disabling the third tab but the enabled property on TabViewItem is ignored.
In short, I've tried everything I can think of and I'm unable to change the TabViewItem's in any way. I realize the underlying implementations are likely imposing some restrictions, but still, is there any way I can control whether the third tab is visible?
This doesn't really answer the question, but it does solve my problem. I can have two separate app-root files, say app-root2 and app-root3, then in app.js I can apply logic and start the appropriate one:
if (<condition>)
application.run({ moduleName: "app-root2" });
else
application.run({ moduleName: "app-root3" });
Edit 4/10/2022: I ended up switching to the BottomNavigation component and dealt with the same issue. That, and the accompanying solution, is described in this post.

If you forget to close a HTML-Tag, Chrome will validate your code and try to fix problems like this.
I had a major problem because I forgot a closing Form-Tag, and instead of closing it correctly, Chrome deleted a following form, not the inputs, simply the Form-Tags.
When I looked at the Source Code itself, the Form-Tag was there, but not in the Elements-Tab in the console.
So at first, I thought it must have something to do with some JS deleting this DOM-Node and set a DOM-Breakpoint to find the script.
To cut a long story short, it took me hours to find out, that no JS deleted my form, but Chrome itself thought: There is a missing so I delete some other to fix that...
Is there any possibilty to see if Chrome automatically changes your DOM?
Thank You!
The browser Engine does indeed. They use string replace methods, although it happens internally.
<div>
</div>> // mistake
<div> //missing end tag
<div></div>
---------------------------------------------------
Methods
file=file.stringreplace('>>', '>')
an uneven count will add the missing div just after the next beginning div and conditionally if the missing is not found by the end of the file:
file=file.stringreplace('
<div>', '</div>
<div>')
The Parsing Engine after the missing and broken tags are repaired then parses the file and can then with a positive count set the screens GUI widgets by opening and closing tags as GUI Frames. It does this by adding tokens delimiters to the actual div tags making them easily distinguished from each other.
<div1s>
</div1e>
<div1s>//section columns
<div2s></div2e>
<div2s></div2e>
<div2s></div2e>
</div1e>
<div1s>Footer</div1e>
-----------------------------------------------------
The GUI Frame Tokens
for each "<dive1>"{
FrameCreate(CSS--ATTRIBUTES FROM ASSOCIATIVE ARRAYS--)
//the GUI Frame Widgets VERTICAL SECTIONS
}
//Next it finds the nested divs2 and embeds these into the thir parents above but with embedded Text Widgets also.
FrameTextBoxCreate(--CSS MATED ATTRIBUTES RULES--)
div3 etc------and so on.
In fact it is in the WebView GUI Widget Sets in its customized Mosaic Canvas Widget Sets in Chrome would be where they are repaired.
Im trying to install tinymce to use with my text editor to allow the user to have a text box just like the stack overflow one. I cant get it to display though
ive put this in the head of my index file
<script src='https://cloud.tinymce.com/stable/tinymce.min.js'></script>
<script src='https:https://cloud.tinymce.com/stable/tinymce.min.js'>
</script>
<script src="//tinymce.cachefly.net/4.1/tinymce.min.js"></script>
<script>
tinymce.init({selector:'infotextarea'});
</script>
then in my info page ive put
<textarea id="infotextarea">Your content here.
</textarea>
can anyone explain why its not displaying
It may be that at the time you run the tinymce.init function, it is not yet rendered and there is no textarea in the DOM.
Try debugging your code on the following line:
<script>
debugger;
tinymce.init({selector:'infotextarea'});
</script>
When the web's execution has stopped on that line, in the development console of your browser type the following:
$('#infotextarea').length
If the size is greater than 0, textarea exists at that moment and it is another problem, but if it shows 0 is that you have not yet created that view, this will help us get more information about your problem.
If you want to target a <textarea> by ID you need to use a valid CSS selector.
selector: "#infotextarea"
(note the # at the beginning of the string)
I would also note you appear to be loading TinyMCE 3 separate times - I have no idea why you would need to do that - loading it once should be sufficient
Its not a perfect answer to my question, but i used ckeditor and it worked perfectly.
I must have a mistake somewhere that i or my team could not find with tinymce
The below screenshot shows how my iron-data-table element looks when it first loads. Notice the data is missing and the headers are not fully formatted (the width seems to be too small to show the column header labels).
However, if I enter a character in the filter fields or click one of the sort buttons, the iron-data-table seems to re-draw itself and it looks fine. The columns and headers render properly and the data populates the table as expected.
This problem started when I added some directories to my file structure nested my iron-data-table inside neon-animated-pages. I double checked and all my imports are loading correctly. But I suspect that, somehow, there is a slight delay in fetching the data and somehow the table might be trying to render before the data arrives and not refreshing after the data arrives.
So I tried to add the following function. But to no avail. There is no render() method for iron-data-table.
<iron-data-table id="grid" ...
....
attached: function() {
this.async(function() {
this.$$('#grid').render();
}.bind(this), 500);
},
What could be causing this behavior? And what should I try next?
Edit
This plunk demonstrates the desired iron-data-table behavior.
This plunk demonstrates my problem behavior. (Not finished yet. Currently in progress.)
The configuration is approximately as follows.
parent-el.html
<neon-animated-pages>
...
<container-el...>...</container-el>
</neon-animated-pages>
container-el.html
<child-el ...>...</child-el>
child-el.html
<iron-data-table ...></iron-data-table>
Edit 2
Based on #SauliTähkäpää's comment, I tried the following fix unsuccessfully.
parent-el.html
<neon-animated-pages id="animator" ...>
...
<container-el...>...</container-el>
</neon-animated-pages>
...
attached: function() {
this.async(function() {
this.$.animator.notifyResize();
}.bind(this), 50);
},
Not that familiar with neon-animated-pages but by looking at the docs, it should call notifyResize() on selected pages as long as they extend iron-resizable-behavior.
So I think your options are either to make sure <container-element> and other elements in the tree are extending iron-resizable-behavior OR override the resizerShouldNotify to notify the grid directly. See more here: https://elements.polymer-project.org/elements/neon-animation?active=neon-animated-pages#method-resizerShouldNotify
To explicate for anyone who follows this question later...
Per #SauliTähkäpää's accepted answer, I successfully added the following code to each element in the chain (i.e., beginning with the element containing neon-animated-pages and ending with the element containing iron-data-table — in this example, that would be parent-el, container-el, and child-el).
parent-el.html, container-el.html, child-el.html.

I have a simple image viewer webpage on gitpages but before I push the next group of images I want to condense all of my images into an array using angular.
The test I have made here uses only 4 photos that are in the same folder as every other file.(they are jpegs)
my js file is set up like this with a factory for the array and a controller.
angular.module('beamModule',[])
.factory('imageFactory', function(){
return {
getImages: function(){
return ['beam1.jpg','beam2.jpg','beam3.jpg','beam4.jpg'];
}
}
})
.controller('Photos', function(imageFactory){
this.images = imageFactory.getImages();
});
I don't think anything is wrong with this array but maybe I am overlooking something?
The HTML that I am using and the section that is giving me trouble when I check the developer tools is below.
<div class="imgcontainer" ng-controller="Photos as photosController">
<img ng-repeat="src in photosController.images"
ng-src="beamModule.js/{{images}}">
</div>
I am not sure if I am supposed to be using an ng-class attribute in the css or if there is something else that needs removed?
The developer tools are returning this value for each of the images (they are repeating just not showing)
<img ng-repeat="src in photosController.images" class="ng-scope">
Why is the ng-scope class being put in here and the ng-src is being removed?
EDIT FIXED
Ok to the person who answered so quickly and simply you are the real mvp here.
You said to change the ng-src="beamModule.js/{{images}}" to read {{src}} instead.
Once I tried this it still didnt work but then I checked the dev tools and noticed it was attempting to pull the files from the js file and not the actual file so I just changed it to this and now it works great! Thank you.
ng-src="{{src}}"
The ng-src attribute needed to point to the repeat instead of the js file.
ng-src="{{src}}"
Is it possible to force the sitemap control to render the menu when the current action is not listed in the MVC.sitemap file?
I have a simple top nav. When the current action is in the sitemap, the call to .Menu() will render the correct <ul><li>.. data. However, if I got to a page that is not in the sitemap such as /Home/Login, then it will not render any html at all (not even a comment, just empty space). This isn't an [authorize] issue; the menu is fine when i'm in '/Home/Index'.
It seems like it should render what was requested, but just not set the IsCurrentNode and IsNodeInPath properties. Here is the call I am making
<div id="main-nav">
#Html.MvcSiteMap().Menu(0, true, true, 1)
</div>
The Mvc.sitemap file:
<mvcSiteMapNode title="Home" controller="Home" action="Index">
<mvcSiteMapNode title="Form New Human" controller="Person" action="Create"/>
<!-- there is no mvcSiteMapNode for "Home" "Login" -->
</mvcSiteMapNode>
Found the way around it. It apparently isn't a built in extension method, or at least I couldn't find one. You could call Html.MvcSitemap().Menu(Html.MvcSiteMap.Provider.RootNode,...) but I didn't want to instantiate the helper twice.
<div id="main-nav">
#{
var sm = Html.MvcSiteMap();
#sm.Menu(sm.Provider.RootNode, true, true, 2); // 2 levels (home, plus main nav)
}
</div>
Looking around in the disassembly seems to show that it works a little like this:
You really need a starting node
If you don't give it one, it tries to find one based on the current node
plus restrictions (forward searching, depth restrictions, etc)
if you want nodes from level 1, you have to know what level you are on
Since that returns null, starting node is null, which means the helper writes an empty string
There may be a combination of tricks, or an overload or two, which can be finagled into doing this, but I can't find it right now. This works for my needs (simple top menu). There has to be a simpler way to do this, something with wild cards, or route based, with a closest match thing going on. I figured menus were a fairly standard part of a web app, and this would be covered :)
