First of all I know I am going to have to change the title, hopefully I can better form my question based on the answers.
I am working on a breadcrumb using angular (let me know if the link fails) but for some reason it isn't working as I would expect. Everything seems fine but when I click the link to go to the next page (sorry in advance for the annoying alert). I get the following error...
Uncaught TypeError: Cannot read property 'addCrumbs' of undefined
The directive is clearly working so I am guessing it is this line that is causing the issue...
angular.element('#crumb').scope().addCrumbs(crumbs);
Can someone explain why this is not working?
Why you'r doing it wrong :)
First of all, Angular is designed for single page applications and can simulate navigation between pages through modules like ngRoute (official) or ui-router (from Angular UI Team, more powerful, more complicated).
Your example doesn't follow the "Angular way" cause you have two "index" page, I mean, Angular (and your app) is re-loaded each time you click on an internal link so you can't share variables between pages (in your case you want a "breadcrumb" shared between pages).
Your breadcrumb directive should share the breadcrumb array via data binding instead of using an external controller explicitly. See here for more infos.
The ng-repeat directive should be applied to the li element instead of the ol element.
Updated Plunkr
See the updated version of your Plunkr.
I added ngRoute module and separated pages. BUT I think it's not a very reusable and clean way for breadcrumbs.
Conclusion
I recommend you to use a dedicated module to handle your breadcrumb, like ng-breadcrumb (see the demo here)

I am trying to create two tabs using Angular UI (Bootstrap), in which one tab lets the user input HTML, and the other tab serves as a "Preview", rendering the HTML provided.
To handle the preview, I am using the contenteditable directive demonstrated here.
However, this directive does not seem to be working using Angular UI tabs. I believe there may be a scope issue at play, but I haven't been able to track it down. I have already found examples of "gotchas" here, but this doesn't seem to be the issue in my case.
A Plunker of non-working code can be found here. In this example, not only is the HTML not getting rendered, but the scope updates seem to be sporadic.
Any help is greatly appreciated!
You can do this without that directive at all. You just need to use the $sce service in angular. See this plunk
I read about angularJS routing. I want to implement it in my web app, but unfortunately I have a rather difficult situation changing to routing now I think. This is how my app works now (and I know it's probably not the way it should, but it does work):
I have one controller for the whole app.
The view is built with some divs, one of which is a menu div. The others are 'partial' views as angularjs calls them I guess. But the problem I see here is that two of my partial views can be shown at the same time (page is built like this, partial view only takes a portion of the page for itself).
So what I am doing is: I click the button on the menu -> one partial view shows up (ng-show), then I can click something on this partial view to get the second partial view opened on the same page (menu and first partial must stay the way they are).
At the moment I include partials within some divs with php include (which is I am sure the wrong way) and the divs have ng-show on them so that nothing is shown on the beginning. Then I manipulate all the clicks in the menu with setting ng-show parameters of all my partials (views). So if one button is clicked I hide all the others (with ng-click and a function inside controller). But this is tedious work and not the angularJS way and that is why I am asking this question here.
Example of my included partial (stripped of all unnecessary css classes etc):
<div ng-show="showNames">
<?php include_once("views/AREA1/names.php") ?>
</div>
And names.php has for instance just some few elements with ng-repeat and other angularJS directives… I have many includes like that and they work with just ng-show manipulation very well. But now that I grasped some of the AngularJS concepts I see that I made a mistake…
To sum up: how can I use angularJS routes (with ng-view perhaps?-not necessary) to show views within my web app? (taking into account the situation that I have described above). I just want user to be able to know on what "part of page" he is at any given moment.
EDIT: I went trough this and I reckon I could work it out: I need a structure similar to the one in this example 2.1 Online Demo, but furthermore I need to be able to click something on ng-view which should open another view (first one should stay in place). Any idea how to accomplish this?
By using routing feature in AngularJS, the html content of ng-view will be totally replaced by the new partial. You should not use ng-view for such a purpose like showing multiple partials at the same time.
But you can think about mix the ng-view and ng-include.
Let's say, we click each item on the menu, ng-view changes the sub-partial, you can have ng-include in your sub-partials which we can all it here like sub-sub-partial.
Try reading ng-include
AngularJS has ng-view which would contain the main theme of current context, rest of the UI elements are all managed by ng-include. Routes also work in sync with nv-view.
If your view requirement are complex look at ui-router component that supports various combinations.
I updated angularjs to 1.2.0-rc1 and added in ng-route as a dependency and added the angular-route.js file. In this build it is now separate.
Clicking on a link for example that has a bookmark href assigned which i used for bootstrap..
href="#collapse1"
Now angularjs is actually trying to change the route to #/collapse1
Is this a bug or am i missing something
Can anyone help?
Is there some additional configuration that i need to do to stop this from happening ?
Expected behavior
The expected behavior is what happens in angular before (i think i was using 1.0.8) ... the link does nothing as far as angularjs is concerned i.e. NO ROUTE CHANGE, of course bootstrap picks does its own thing and shows an accordion in this example.
This angularjs feature.
Use
href="#/#collapse1"
for correct location change.
because i had the same problem. At my point Bootstrap wasn't loaded and so he tried to route this collaps as an route. After i loaded bootstrap manuel to this view, it works fine.
Hope you understand my bad english ;)
I'm fairly new to Angular but I've been using it the past few weeks and have managed to work out most of the problems I've come across. This one however has me stumped.
I have an app that pulls in tweets from Twitter then - using an angular filter - pulls out all the urls and styles them as links. This part works fine but the client decided that links from Twitter were't safe so they wanted a disclaimer to fire every time a link was clicked. Simple enough - I hijacked the link and swapped the href for an ng-click="openLink('url')". This is where the problem occurred - the ng-click doesn't work.
I'm pretty sure the problem has something to do with $compile() - I've had similar issues before - but I have no idea when or where to call it.
I've created a Plunkr that is a lite version of what I'm after. The link at the top isn't loaded in dynamically and fires the alertUrl() function fine, but all the links generated by the filter fail.
I'm probably missing something really simple but it's been bugging me a while now so any help will be massively appreciated.
Thanks,
Sam
Well you are correct that the html\content that you emit needs to be compiled for angularjs to resolve the alert function.
I have changed your plunker, and inject a compile directive (from here)
See it in action here
The basic idea here is to compile the content produced from twitter feed dynamically.
<p compile="tweet.text | convertLinks"></p>
My full code is at:
http://plnkr.co/edit/6EQFXL?p=preview
The "delete row" and "delete column" buttons are dynamically created. Right now when I click on them nothing happens. How can I get them to run the corresponding handlers? Is there a better way to do what I am trying to do (make a resizable and editable grid)?
Main Issue
The problem is that your creating the html for the button without compiling it through angularjs. You could just send this through the $compile service to get it to work but that's not the angular way. The better option would be to create a directive for tbody and put code there either as a template or in the compile phase of the directive. There's a great video by Misko Henvrey (lead engineer from angular) about creating directives at http://www.youtube.com/watch?v=WqmeI5fZcho. Also you might want to check out the ng-grid created by the angular-ui team at https://github.com/angular-ui/ng-grid to get an idea of how to put together a semantic grid component.
Side Issue
When trying to think in angular you really need to start thinking of the functionality you need and architecting a solution for the functionality (e.g. the directive (s)). What you've done in this question instead is thinking the traditional javascript way (nothing wrong with that in general), which is to say ok I'm limited by what html gives me and I need to tie my javascript in to the stuff I'm given through hooks on classes and ID's. I highly recommend taking a look at "Thinking in AngularJS" if I have a jQuery background? to get a more complete view of angular vs jquery/traditional javascript.
