How would one use the method="post" with nested forms like are found in this example: http://jsbin.com/gohefojiqa/1/edit?html,js,output ?
I'm guessing it has something to do with this: https://scotch.io/tutorials/submitting-ajax-forms-the-angularjs-way but I'm not sure how to implement it in a multistep/nested form like are present in the angular-wizard form.
Turns out my HTML was messed up...
Also, an alert in the example was also throwing it off a bit too. Fixed those two things and now we're good.

I am trying to use Angular Bootstrap Confirm by Matt.
In his demo (click here), it is mentioned that html can be used in the message. His code:
Are you really <b>sure</b> you want to do this?
I changed that to
Are you really <b>sure</b><br> you want to do this?
and it still worked. But if I try to add any complex element like input or button, it does not work.
Enter <b>Yes</b><br> <input type='text'> <br>and click 'Yes'
Is there a way to add input or textarea to the message?
You would have to fork their code, based on the source, it is using a class, so you could not do this through the interface.

I was doing code review and found custom directive with html tags inside attribute:
<form-field help="Use <b>foo</b> option to blah blah"></form-field>
I find it very unusual, and thought that it will not work in older browsers. But when I and author of this code checked - it turned out that it works in every version of IE we had (10+) and in Chrome/FF without any troubles.
Moreover I checked it in W3C validator (validator.w3.org) and it looks like HTML allows to have unescaped tags inside attributes. This SO answers Can data-* attribute contain HTML tags? confirms that too.
So my question is: Can this make troubles when used with AngularJS? Will this behavior change in Angular 2.0? And finally is this accepted usage of attributes?
I personally would like something like this:
<form-field>
<help>
Use <b>foo</b> option to blah blah
</help>
</form-fild>
Yes, you can do that with ng-bind-html directive. Take a look at this: https://docs.angularjs.org/api/ng/directive/ngBindHtml
I'm having trouble with a task that seems trivial to me, but I just haven't got it right yet. I have a form and in that form I use a home-cooked directive called time-range. This directive has two input fields for start-date and end-date. Later on, in the view where the form is defined I want to validate each field using code similar to this:
<li ng-show="form.createAssignment.fromDateField.$error.dateinput">{{::$parent.lang.from_date | capitalize}} {{::$parent.lang.has_to_be_on_format}} {{::$parent.lang.yyyy_mm_dd}}</li>
Well, this works just fine, BUT only for validating the input field in the last directive in the form. If I enter something wrong in the first directive, the form is invalid (and thus the error list is shown) but the text that specifies what is wrong does not show up, presumably because the input in the last directive is correct.
So, somehow I would like to be able to qualify which directive I refer to, maybe something like:
<li ng-show="form.createAssignment.directive1.fromDateField.$error.dateinput">{{::$parent.lang.from_date | capitalize}} {{::$parent.lang.has_to_be_on_format}} {{::$parent.lang.yyyy_mm_dd}}</li>
However, I haven't yet succeeded with this. Does anyone have a suggestion how this can be done?
ng-form uses input name for validation, so it's hard to target specific input if you are using ng-repeat or repeated directives.
One option would be using ng-form directive, which means creating an inner form inside the form. There are plenty of guides on how to do this.
Another option would be passing a unique name (prefix/suffix) via your directive parameter. But unfortunately the variable name won't work automatically, you'll have to compile the template again after the name is passed in.
I am using angularjs from 2 months but never comes to problem like this, so thought of sharing with you people and getting some good suggestion on that. Here I am trying to apply ul/nav-group element dynamic values. Everything is working fine means, if I see developer tools on browser it gets value and everything, but not the +/- sign. I search on google its saying that it loads after DOM creation so it is not showing that. But no buddy tells the solution for that.
Consider my code:
<nav:group ng-repeat="parentChild in parentChildList" title="{{parentChild.filterText}}">
<nav:item data-view="/ui/icons/fa" ng-repeat="childs in parentChild.childList" data-icon="fa fa-lg fa-fw fa-plane" title="{{childs.filterText}}" />
</nav:group>
The value for particular fields are straight forward means its simple list.How the directive can solve this problem.
Appreciate any suggestions . Thanks.
Add an ng-cloak directive on the body tag of your app to prevent loading the element until angular has finished loading.
Your body tag would look like this:
<body ng-cloak>
...
</body>
You could also fix this by using promises in your services, that is definitely the best practice regardless, but ng-cloak is a quick and easy fix.
Hope that helps! If ng-cloak doesnt work for you post snippets of your controller and service and I will help you add promises.
Good Luck!

I am starting with angular and I often see two different approaches of using a module:
<input autocomplete options="..."/>
And:
<autocomplete options="..."/>
I think the first one is a better options since it uses the native HTML tags.
Is there a reason, or advantage of using the second approach?
In my opinion the HTML code becomes quite strange ...
