I cannot figure out why my ng-click inside of my directive will not fire the fooControls clickTest. Why is clickTest not firing and logging to the console? is there a better way of doing this?
Directive
app.directive('fooList', function () {
return {
restrict: 'E',
templateUrl: './app/views/fooList.html',
scope: { obj: "=" },
controller: 'fooController',
controllerAs: 'b'
};
});
Controler
app.controller('fooController', ['$scope', function ($scope) {
$scope.obj = [];
$scope.ClickTest = function (num) {console.log(num);};
}]);
HTML
<div ng-repeat="book in obj" class="container">
<div class="row">
<h4 class="pull-right"><button class="btn btn-small" ng-click="b.ClickTest(1)">ClickTest</button></h4>
</div>
<br />
</div>
EDIT
The above html is a copy paste of foo-list. The full html is
<html>
<head>
</head>
<body>
<foo-list obj="searchResults"></foo-list>
</body>
<html
Your html should be changed to have the ClickTest function applied directly to the scope, not a variable in the scope. You also need to include a <foo-list /> tag for your directive.
<div ng-repeat="book in obj" class="container">
<div class="row">
<!-- Change b.ClickTest(1) to ClickTest(1)-->
<h4 class="pull-right"><button class="btn btn-small" ng-click="ClickTest(1)">ClickTest</button></h4>
</div>
<br />
<!-- Insert a foo-list tag -->
<foo-list obj="searchResults"></foo-list>
</div>

I recently had a coding challenge that I got rejected for because it was garbage. Didn't have a lot of time so I threw everything together in one giant HTML file/angular controller, so I'm in the middle of rewriting it in templates to try to make it more reusable. So far it's going well, but I'm having some trouble with an html template not being able to access ng-model. Whenever I console.log the ng-model, I get undefined.
Here's the top layer HTML:
<div class="col-md-8 box">
<div class="panel panel-default">
<div class="panel-heading">Companies</div>
<div class="panel-body">
<div ng-repeat="company in companies">
<div class="panel panel-default">
<div class="panel-heading">Name: {{company.name}} <button ng-click="companies[$index].editCompany = !companies[$index].editCompany" class="pull-right">EDIT COMPANY</button></div>
<div class="panel-body" ng-if="!companies[$index].editCompany">
<p>Address: {{company.address}}</p>
<p>Revenue: {{company.revenue}}</p>
<p>Phone Number: {{company.phone}}</p>
<button ng-click="getPeople(companies[$index]._id, $index); companies[$index].viewEmployees = !companies[$index].viewEmployees">People Who Work Here</button>
<div ng-if="companies[$index].viewEmployees">
<show-employees-list></show-employees-list>
</div>
</div>
</div>
<div ng-if="companies[$index].editCompany">
<edit-company-directive></edit-company-directive>
</div>
</div>
</div>
</div>
</div>
And here's the HTML for the directive:
<div class="employee-box" ng-repeat="employee in companies[$index].employees">
<span class="glyphicon glyphicon-edit pull-right" ng-click="companies[$index].editEmployee = !companies[$index].editEmployee; clickEdit()"></span>
<span class="glyphicon glyphicon-remove pull-right" ng-click="deletePerson(employee._id, $index, companies[$parent.$index].employees)"></span>
<div ng-if="!companies[$index].editEmployee">
<div>
<p><b>Name:</b> {{employee.name}}</p>
<p><b>Email:</b> {{employee.email}}</p>
</div>
</div>
<div ng-if="companies[$index].editEmployee" class="form-body">
<form name="editPersonForm" ng-submit="editPerson(employee._id, $parent.$parent.index, $parent.index)">
<input type="text" ng-model="nameEdit" id="nameEdit" placeholder="Employee" class="form-control" required></input>
<input type="text" ng-model="emailEdit" id="emailEdit" placeholder="Email" class="form-control" required></input>
<button type="submit" id="submitButton" class="btn btn-success form-actions">Submit</button>
</form>
</div>
</div>
And here's the directive code:
'use strict';
(function() {
angular
.module('sigFig')
.directive('showEmployeesList', showEmployeesList);
function showEmployeesList(sigFigFactory) {
var directive = {
restrict: 'E',
templateUrl: 'Directives/showEmployeesList/showEmployeesList.html',
scope: '=',
require: '^parentDirective',
link: link
};
return directive;
function link(scope, element, attra, controller) {
scope.deletePerson = function(id, index, employees) {
sigFigFactory.deletePerson(id).then(function(response) {
employees.splice(index, 1);
return response;
})
};
scope.editPerson = function(personId, index1, index2) {
scope.person = {
name: scope.nameEdit,
email: scope.emailEdit
};
console.log('person ', scope.person);
};
}
}
})();
I'm thinking it's some sort of scoping issue that I just don't see, and hoping someone can help. When I console.log that person object I get undefined for both properties.
it's good idea to use angular directive, and also you need to read more about it:
you just define scope as variable but it's object, and there isn't scope.nameEdit to console
app.directive("name", function() {
return {
templateUrl: "your.html", //it's string
restrict: 'E',
scope: { //it's object
param1: "=" //var
param2: "#" //string
param3: "&" //method and etc
},
link: function(scope){ //it's function
//scope.param1
//scope.param2
//scope.param3
}
}
})
<name param1="{foo: 'test'}" param2="hello" param3="callback"></name>
with directive you can pass everything from your basic view (controller) to the directive, you can $watch value on change in your controller and more options.
I need to execute a javascript function that resides inside a controller. I need to call the function from within a directive.
The arguments I'm passing are fine. My method name in the controller is "GetAttachments".
When I'm debugging, and using scope, the method name GetAttachments doesn't appear.
Can someone please help me to be able to execute the named function?
Here is my directive. I need to know the proper syntax of the line: scope.GetAttachments(attrs.downloadType, attrs.downloadId). Note that my arguments are fine...
.directive('download', ['$modal', function ($modal)
{
return {
restrict: 'E',
transclude: false,
replace: true,
template: '<a style="padding-right: 5px; color:#fff !important;" class="pull-right" href="#" ng-click="opendownload()"><i class="fa fa-files-o fa-lg" style="padding-right: 5px"></i>Download</a>',
link: function (scope, elem, attrs, controller)
{
scope.opendownload = function ()
{
$modal.open({
templateUrl: root + 'AccountingModule/modal/attachment/download-modal.html',
size: 'md',
backdrop: true,
controller: 'downloadSPDocumentsController as downloadCtrl',
resolve: {
attributes: function () { return attrs; },
}
});
scope.GetAttachments(attrs.downloadType, attrs.downloadId)
}
}
}
}])
Here is my JS function inside the controller:
module.controller('downloadSPDocumentsController', ['$scope', '$http', '$modalInstance', '$location', '$window', 'attributes',
function ($scope, $http, $modalInstance, $location, $window, attributes)
{
var viewModel = this;
viewModel.attributes = attributes;
var DocumentDownloadarr;
viewModel.GetAttachments = function (CheckID, FileID)
{
Here is the HTML
<!--<p>For Testing Purpose: Download Type: {{downloadCtrl.attributes.downloadType}}</p>
<p>For Testing Purpose: ID: {{downloadCtrl.attributes.downloadId}}</p>-->
<div class="modal-header">
<h3 class="modal-title">File Download</h3>
</div>
<div class="modal-body" cg-busy="{promise:downloadCtrl.promise}">
<ul ng-init="downloadCtrl.Init()" class="list-unstyled">
<li ng-repeat="item in downloadCtrl.DocumentDownloadarr">
<div class="col-sm-12">
<div class="form-group">
<div class="col-sm-10">
<input type="text" class="form-control" ng-value="item.FileDescription" ng-readonly="true" />{{item.ExternalDocumentId}}
</div>
<div class="col-sm-2">
<button type="button" class="btn btn-default" ng-click="downloadCtrl.DownLoadAttachment(item.ExternalDocumentId, item.FileDescription)">Download</button>
</div>
</div>
</div>
</li>
</ul>
</div>
<div class="modal-footer">
<div class=" btn-toolbar pull-right" role="toolbar">
<!--<div class="btn-group" role="group">
<button type="button" class="btn btn-default" ng-click="downloadCtrl.GetAttachments(downloadCtrl.attributes.downloadType, downloadCtrl.attributes.downloadId)">List Attachments</button>
</div>-->
<div class="btn-group" role="group">
<button type="button" class="btn btn-default" ng-click="$close()">Close</button>
</div>
</div>
</div>
You need to expose your function GetAttachments in the controller via the scope.
Instead of
viewModel.GetAttachments = function (CheckID, FileID)
try this:
$scope.GetAttachments = function (CheckID, FileID)
However please note that this will work only if the directive and the controller is sharing the scope (which I think is the case on your code). However if you want to use isolated scope (for better modularity and re-usability) of the directive , then you will have to pass a reference of the method (in your controller) to the directive's scope using '&' binding.
Take a look at this fiddler here for a demo of isolated scope and calling function in controller from directives
You might want to consider raising an event in your directive using something like:
$rootScope.$broadcast('myEventHappened');
And then in your controller listen for it with something like:
$scope.$on('myEventHappened', function() {});
This approach will keep you from tightly coupling your directive to your controller.
I'm trying really hard, but I can't find where is my problem.
I created a custom directive and it should iterate some HTML to draw the right content on the screen.
The problem is that my ng-repeat does not iterate my array. I search on stackoverflow but what I found didn't help me.
Here is my directive (it's in an external file):
app.directive('logtab', function(){
return {
restrict: 'E',
templateUrl: 'view/templates/log-tab.html',
replace: true,
controller: ['$scope', 'api', function($scope, api) {
$scope.logState = false;
$scope.logData = [1,2,3,4];
$scope.loadLog = function() {
api.doRequest({
path : $scope.path,
method : "GET",
broadcast : BK_LOG
});
};
var bk = $scope.$on(BK_LOG, function(key, value){
$scope.logState = true;
console.log($scope.logData);
bk();
});
}]
};
});
And here is the directive HTML that will be rendered:
<md-tab ng-click="loadLog()" label="{{i18n['REVISIONS']}}">
<div layout="row" layout-align="center" layout-padding ng-show="!logState">
<div layout="column">
<div>
<md-progress-circular md-mode="indeterminate" md-diameter="130"></md-progress-circular>
</div>
<div>
{{i18n['LOG_LOAD']}}
</div>
</div>
</div>
<div layout="row" ng-show="logState" layout-padding>
<div layout="column">
<div ng-repeat="xyz in logData">
{{xyz}}
SOME CONTENT HERE
</div>
</div>
</div>
</md-tab>
Thanks in advance!
I removed other components from your directive code and kept it at bare minimum. The code is working fine as expected. Please see below.
Index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Index</title>
</head>
<body ng-app="myApp" >
<logtab></logtab>
<script src="angular.js" type="text/javascript "></script>
<script src="app.js" type="text/javascript "></script>
</body>
</html>
app.js
var myApp = angular.module('myApp', []);
myApp.directive('logtab', function(){
return {
restrict: 'E',
templateUrl: 'log-tab.html',
replace: true,
controller: ['$scope', function($scope) {
$scope.logState = false;
$scope.logData = [1,2,3,4];
console.log('hi');
}]
};
});
log-tab.html
<div>
{{logData}}
<div layout="row">
<div layout="column">
<div ng-repeat="xyz in logData">
{{xyz}}
</div>
</div>
</div>
</div>
Please use a couple of console.log's to identify the exact location. I suspect that there must be some thing wrong with the other parts of the directive or may be logState is set to false??
You can always separate the controller from the directive:
app.directive('logtab', function(){
return {
restrict: 'E',
templateUrl: 'view/templates/log-tab.html',
replace: true,
scope: {
log: '='
}
};
});
Then in your controller
app.controller('MyController', ['$scope', 'api', function($scope, api) {
$scope.logTab = {
state: false,
data: [1, 2, 3, 4],
loadLog: function() {
api.doRequest({
path : $scope.path,
method : "GET",
broadcast : BK_LOG
});
}
};
var bk = $scope.$on(BK_LOG, function(key, value){
$scope.logTab.state = true;
console.log($scope.logTab.data);
bk();
});
}]);
Then change your HTML to:
<md-tab ng-click="log.loadLog()" label="{{i18n['REVISIONS']}}">
<div layout="row" layout-align="center" layout-padding ng-show="!log.state">
<div layout="column">
<div>
<md-progress-circular md-mode="indeterminate" md-diameter="130"></md-progress-circular>
</div>
<div>
{{i18n['LOG_LOAD']}}
</div>
</div>
</div>
<div layout="row" ng-show="log.state" layout-padding>
<div layout="column">
<div ng-repeat="xyz in log.data">
{{xyz}}
SOME CONTENT HERE
</div>
</div>
</div>
</md-tab>
And call it with
<logtab log="logTab"></logtab>
Updated my answer based on OP's explanation.
Created a fiddle here: https://jsfiddle.net/frishi/bzbbo5da/14/
I simplified the directive definition a little, removed the api part of it.
I also changed the directive's template to include the ng-repeat part of it.
//....
restrict: 'E',
template: `<p><div ng-repeat="xyz in logData">
{{xyz}}
SOME CONTENT HERE
</div></p>`,
replace: false,
scope: true, // <- needs to be set
//....
You are missing the scope parameter in the directive definition object. You have to set it to scope: true for your directive's template to be able to access a variable defined on the directive controller's scope.
Question: Why doesn't my simple directive have access to its controller when the element is used on certain pages?
Additional Info: The directive works on the main page. The HTML I could not use my directive on is called using ui-view and is included below.
<div ui-view></div>
Directive:
var postcardAppDirectives = angular.module('postcards.directives', ['postcards.controllers']);
postcardAppDirectives.directive('postcardLink', function () {
return {
restrict: "AE",
template: '<div class="well">{{ ctrl.ownerObj.user }}</div>',
controller: 'postcardLinkController as ctrl'
}
});
Controller:
var PostcardsControllers = angular.module('postcards.controllers', ['postcards.factories', 'postcards.services']);
PostcardsControllers.controller('postcardLinkController', [function ()
this.ownerObj = {
"user": 'test_owner',
"pointofthis": 'inane testing'
}
}]);
HTML (Does Not Work):
<div ng-controller="DashboardAccountController as infoCtrl" class="container full-container">
<!------------------ DIRECTIVE REFERENCE HERE -------->
<postcard-link></postcard-link>
<h1>
<small>Welcome</small>
<username-text></username-text>
</h1>
<img ng-show="infoCtrl.user.member_profile.profile_image" ng-src="{{ infoCtrl.user.member_profile.profile_image }}"
style="min-height:100px;height:100px;" alt='profileImage'/>
<button type="button" class="btn btn-link col-md-offset-2" ng-click="infoCtrl.loadPage()">Modify Account</button>
<div class="row">
...
HTML (Working Fine)
<ng-include src="'static/app/carousel/_carousel.html'"></ng-include>
<postcard-link></postcard-link>
<div class="container">
<section style="text-align: center">
<h1>How It Works</h1>
I see you used different module that's why one module don't know another module directive. you should use same module.
Like:
js:
var app = angular.module('postcards', []);//add dependencies in []
app.directive('postcardLink', function () {
return {
restrict: "AE",
template: '<div class="well">{{ ctrl.ownerObj.user }}</div>',
controller: 'postcardLinkController as ctrl'
}
});
app.controller('postcardLinkController', [function () {
this.ownerObj = {
"user": 'test_owner',
"pointofthis": 'inane testing'
}
}]);
use as usual html:
<postcard-link></postcard-link>
I have a directive which, when called, passes in a controller and an array.
In the controller I pass in, there is an object I want to loop over.
my html looks like this:
<div class="row">
<div class="col-md-6">
<div class="jumbotron" ng-controller="protocolCtrl as pctrl">
<button type="button" id="protocol" class="btn btn-primary btn-lg" ng-click="pctrl.getUpdatedList()"
data-toggle="modal" data-target="#modal">Modify Current Protocols</button>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive list="pctrl" headers="['ID', 'Protocol']"></modal-directive>
</div>
</div>
<div class="col-md-6">
<div class="jumbotron" ng-controller="categoryCtrl as cctrl">
<button type="button" id="category" class="btn btn-primary btn-lg" ng-click="cctrl.getUpdatedList()"
data-toggle="modal" data-target="#modal">Modify Current Categories</button>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive list="cctrl" headers="['ID', 'Category']"></modal-directive>
</div>
</div>
</div>
My problem is that no matter what I do, it's always the FIRST directive in the html that showes up, no matter what button I press.
My directive looks like this:
.directive('modalDirective', function(){
return {
restrict: 'E',
templateUrl: '/directives/modal-directive.html',
scope: {
list: '=',
headers: '='
},
link: function(scope, element, attrs){
console.log(attrs.list + ' | ' + attrs.headers);
}
};
});
My modal-directive.html looks like this:
<table class="table table-striped">
<thead>
<tr>
<th ng-repeat="h in headers"> {{ h }} </th>
</tr>
</thead>
<tbody>
<!-- Loop through -->
<tr ng-repeat="l in list.list">
<!--Access the actual values inside each of the objects in the array-->
<td ng-repeat="data in l"> {{ data }} </td>
<td>
<button type="button" class="btn btn-primary btn-sm"
data-toggle="modal">Edit</button>
</td>
<td>
<button type="button" class="btn btn-danger btn-sm" ng-click="list.removeData(l)"
data-dismiss="modal">Remove</button>
</td>
</tr>
</tbody>
</table>
Am I using isolated scopes wrong, or is it something else I need to change in order to make this work?
Update
Here is a fiddle, that demonstrates the problem.
No matter which button i click, it displays the same text in the modal body.
You don't really need two controllers and two directives to achieve this. Below is an example of how you can do this. Notice I moved the controller to the row instead of having separate controllers for each column. The controller myCtrl now handles the click functions which are bound to the buttons using the ng-click attribute. This then determines the which text should be placed where by calling there respective functions. IE proto() and cat()
Now this may not be ideal for your situation depending on how you plan on the architecture of your application. But it works for your current problem in terms of what you have provided.
HTML
<body ng-app="TM">
<div class="row" ng-controller="myCtrl as modalControl">
<div class="col-md-6">
<div class="jumbotron" >
<button
ng-click='proto()'
type="button" id="protocol"
class="btn btn-primary btn-lg"
data-toggle="modal"
data-target="#modal">Modify Current Protocols
</button>
</div>
</div>
<div class="col-md-6">
<div class="jumbotron">
<button
ng-click='cat()'
type="button"
id="category"
class="btn btn-primary btn-lg"
data-toggle="modal"
data-target="#modal">Modify Current Categories
</button>
</div>
</div>
<!--IN THIS MODAL YOU CAN ADD/CHANGE/DELETE DATA-->
<modal-directive ctrl="modalControl"></modal-directive>
</div>
</body>
Angular JS
angular.module('TM', [])
.controller('myCtrl', function($scope){
$scope.text ='default';
$scope.proto = function() {
this.text = 'Now looking at the protocol part'
}
$scope.cat = function() {
this.text = 'Now looking at the category part'
}
})
.directive('modalDirective', function(){
return {
restrict: 'E',
scope: true,
template: ['<div id="modal" class="modal fade" role="dialog">',
'<div class="modal-dialog">',
'<div class="modal-content">',
'<div class="modal-header">',
'<h4 class="modal-title">Modal Header</h4>',
'</div>',
'<div class="modal-body">',
'<p> {{ text }} </p>',
'</div>',
'<div class="modal-footer">',
'<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>',
'</div>',
'</div>',
'</div>',
'</div>'].join('')
}
});
Demo:
https://jsfiddle.net/DTcHh/10193/
UPDATE:
Okay, I took another look. And even though the above example works. I noticed that I have a few extra things that I didn't necessarily need. For example myCtrl as modalControl doesn't need the as modalControl part. Below is an updated example. I did this one with some different simplified markup.
HTML:
<body ng-app="TestApp">
<div ng-controller="myCtrl">
<button ng-click="one()">One</button>
<button ng-click="two()">Two</button>
<test-directive></test-directive>
</div>
</body>
Angular Example (without Isolated Scope)
angular.module('TestApp', [])
.controller('myCtrl', function($scope){
$scope.text ='default';
$scope.one = function() {
this.text = 'this is one'
}
$scope.two = function() {
this.text = 'this is two'
}
})
.directive('testDirective', function(){
return {
template: "<div id='test'>{{text}}</div>"
}
});
Demo 2:
https://jsfiddle.net/krishollenbeck/v8tczaea/12/
Note this..
restrict: 'E',
scope: true
Was also not needed because I am not using Isolated scope in this example. More info here https://docs.angularjs.org/guide/directive
Please check this JSFiddle.
The reason is that data-target value points to the DOM element id of the modal. If you fixed this id in the directive template, clicking on the button will always initiate the modal with id modal. So you need to make the modalId as another parameter of the directive.
By the way, you can pass a controller to a directive. Just like this JSFiddle:
angular.module('Joy', [])
.controller('MyCtrl', ['$scope', function ($scope) {
this.value = 'Joy';
}])
.directive('passMeContrller', [function () {
return {
restrict: 'A',
scope: {
ctrl: '=',
},
template: '<div>Value: {{ctrl.value}}</div>'
};
}]);
The HTML:
<div ng-app="Joy" ng-controller="MyCtrl as c">
<div pass-me-contrller ctrl="c"></div>
<hr>
<div ng-bind="c.value"></div>
</div>
Because the controller itself is just a JavaScript object.
Just a reminder: you are using protocolCtrl as pctrl, so you need to specify like this.list=....
If you want to pass in a function to the isolated scope, use &.
However, I suggest not to pass in the whole controller to a directive. A controller is designed to:
Set up the initial state of the $scope object.
Add behavior to the $scope object.
Controllers are not supposed to be reused. Usually there are many properties on the $scope, while some of them passed to the directive will not be used by it.
