I have having some trouble utilizing the angular bootstrap-ui btn-checkbox directive and its interaction with a ng-repeat directive. The way the directive appears to be setup is that you have to manually name each individual model for a multi checkbox scenario, which is either not possible within an ng-repeat or I haven't found how to accomplish this.
I found an answer somewhat similar to this issue:
Setting and getting bootstrap radio button inside angular repeat loop
and forked the plunker to better explain exactly what I am seeing as a problem.
The plunker can be viewed:

The answer you linked is the same solution for this problem. Each button within the repeat needs it's own unique property of the model. If they are all set to the same model, as in the plunk $scope.checkboxModel = {id: 0}, when one button is checked, they will all be checked.
So to give each button uniqueness, you could set another property onto the objects within the ng-repeat. This property would hold a boolean value that changes on check. So your model would look like:
$scope.companies = [{"id":2,"name":"A", truthy:false}] // and so on
You would not need to explicitly set this in the controller - just declare the new property right in the button element's model:
<companies ng-repeat="company in companies">
<button type="button" class="btn" ng-model="company.truthy"
btn-checkbox>{{company.name}}</button>
</companies>

I am transitioning from jquery to angularjs. I am trying to develop a small app in SPA style. Left side is the menu that controls the content on the right side. Left side menu has its own controller. When the user selects a checkbox and clicks on 'Go', the checkbox value should be passed to the controller that controls the right side content. Here is the link to the app. Below are the issues I have.
1)I am stumped on a simple problem of accessing checked values of a checkbox. How do I access values of checked checkboxes. The checboxes are on left side menu, and I am using ng-model to currently access the values as below
index.html
<div id="searchOne">
<ul>
<li ng-repeat="searchOneCB in main.checkBoxOneData">
<input type="checkbox" name="firstSearch" id="firstSearch_{{searchOneCB.code}}" ng-model="main.selected[searchOneCB.code]" />
{{searchOneCB.description}}
</li>
</ul>
<button class="btn btn-primary" style="width:80px;margin-right: 10px" ng-click="main.submit()">
Go
</button>
</div>
MainCtrl.js to access the checkbox value.
main.submit = function() {
console.log(main.selected);
}
The values are now in the form of an array as below
[BBBB: true, AAAA: true].
Is this the right way to access the values? What is the best way to retrieve only the checked checbox values?
2) Another question is, once I get the list of checked checkboxes values, how can I pass them to the contentCtrl.js that controls the content on right side?
You should inject the controller into the controller you want to use. The answer has already been answered here is the link.

I have a checkbox that is updated from the model, but then the model is not updated clicking the checkbox.
Within a form I have:
<input type="checkbox" ng-model="acceptEula"> I have read the EULA and I agree
<button type="submit" ng-click="pay()" translate>Proceed to Pay</button>
{{acceptEula}}
Clicking the checkbox, I can see how {{acceptEula}} shows true or false, it works.
When I click the button, I put a breakdown in pay() function. $scope.acceptEula is always false. What could be the problem?
Sorry, the question was not detailed in order to simplify the problem. In reality, I used "ng-switch" in the form.
Finally I have found the problem: "This is a scope inheritance problem due to ng-switch creating it's own scope.". It is well explained at angularjs - ng-switch does not bind ng-model
The solution is to use dot in the model, for example $scope.form.acceptEula
Hi I would like to customize behavior of the ui-select little bit. I use two bootstap themed ui-select controls on my page with the help of templatecaches. In the template, I wired up arrow button click event using ng-click tag. That way I can easily catch the click event on the arrow button, and in my controller I can open a popup using function, for instance:
<button ng-click = "someFunctionInTheScope()">
For instance if I have two of those ui-select elements in my view, I need to differentiate which arrow button is clicked to display the correct popup. Since I am using the same template for two ui-select controls and since theoretically I can have any number of these controls on my page, I can not easily add a parameter to the method in the template to differentiate which arrow image of which ui-select control is clicked:
<button ng-click= "someFunctionInTheScope(1)">
Because both ui-select control would be using the same template code and 1 would be passed to the controller function for both of them.
Therefore I need to find a more clever way of changing the template dynamically once and for each control.
So I thought about having something like
<button ng-click= "someFunctionInTheScope($select.id)">
but when I debug it I see that functions parameter is undefined, every time it is clicked.
Can somebody please show me how to hack this?
There is no id property on the $select object. You're best bet is to pass something through the scope of the element containing the ui-select boxes. In other words, your code needs to generate a unique identifier for each ui-select box you have. This could be the $index property of an ng-repeat block, a timestamp, or something dependent on other context.
A little more context and I can provide a more specific answer.
I'm trying to do a column edit using angularjs & x-editable, with the form defined in the thead attribute. This works when I do the markup for each column individually, but I'm looking to define the columns using ng-repeat, which doesn't work.
It seems like the form controller doesn't get added to the scope, so the x-editable fields can't reference it using $parse(attrs.eForm)(scope); from xeditable.js
My guess is that its some kind of scope issue with the form being defined in an ng-repeat, but I'm new to angular so don't know much more than that.
jsfiddle showing the problem. using an ng-repeat with only one item in it, and the html is not even referencing those properties for testing purposes.
<td style="width: 40%">
<td ng-repeat="header in headers" style="width:40%">
thanks for the help!
It's a bit late but here is the jsFiddle. The trick is to use table form instead of normal form when you create dynamic forms using angular xeditable :)
e-form="rowform"
Link to the documentation on table form (or row editable) is here
use div ng-form="myngformname" editable-form
Quick questions. Im generating part of a form dynamically, namely the radio buttons part and I am using an ng-repeat. To do this I have the following code to loop through and list the radio button options:
<div ng-repeat="choice in question.choices">
<input name="{{q.name}}" type="radio" value={{choice.id}} ng-model="choice_[q.answer]" required /> {{choice.choice}}
</div>
I have two issues with this, firstly, im not sure if I am correctly assigning my ng-model dynamically.
Secondly once the model is created it seems to be in its own scope and unusable outside of the repeat due to it being encapsulated within the repeat div.
Is there a way I would be able to access this model? perhaps just passing it through the parent scope using $parent or so?
Any help would be appreciated.
Thanks
I created a plunker to show how to access your model:
Model access demo
<input type="radio" value={{choice.id}} ng-model="$parent.choice" required /> {{choice.choice}}
I used the same model name for every input in the repeat. This way whichever input is selected becomes the active model. That should solve your model naming issue.
Secondly, ng-repeat creates a scope for every template it produces, so you do want to use $parent to access the model on your controllers scope.
