Call a callback function after rendering the anchor in angularjs - angularjs

I've the following HTML in my layout:
<div class="icon-grid">
<a ng-if="udtTable.config.moreActionIcons" ng-repeat="mai in udtTable.config.moreActionIcons"
ng-attr-data-toggle="{{(mai.modal) ? \'modal\' : undefined}}"
ng-attr-data-target="{{(mai.modalName && mai.modal) ? mai.modalName : undefined}}"
after-render="{{mai.callback}}"
href="{{mai.action}}/{{value.data.id}}"
title="{{mai.tooltip}}">
<span class="{{mai.icon}}"></span>
</a>
</div>
Here is my after-render directive:
angular.module('neogetDataTableServices').directive('afterRender', ['$timeout', function ($timeout) {
var def = {
restrict: 'A',
terminal: true,
transclude: false,
link: function (scope, element, attrs) {
console.log(attrs.afterRender);
}
};
return def;
}]);
Here is my object to repeat
var udtTable = {
config: {
"moreActionIcons" : [
{
"action": 'myaction.php',
"icon": "icomoon-lock-open",
"modal": true,
"modalName": "#mkjax-modal",
"tooltip":"Authorize",
"callback": function() {
alert('hey rendered');
}
},
]
}
}
Now the problem is if I write this line
after-render="helloworld"
Then my directive after-render logs it properly through console.log(attrs.afterRender);
But if I write this like below:
after-render="{{mai.callback}}"
Then the directive doesn't logs function() { alert('hey rendered'); } It says that it is an empty string.
Anybody has the solution?

Try like this:
angular.module('neogetDataTableServices').directive('afterRender', ['$timeout', function ($timeout) {
var def = {
restrict: 'A',
terminal: true,
transclude: false,
link: function (scope, element, attrs) {
scope.$eval(attrs.afterRender);
}
};
return def;
}]);
In html:
after-render="mai.callback()"

It would be better to use an isolated scope.
angular.module('neogetDataTableServices').directive('afterRender', ['$timeout', function ($timeout) {
var def = {
restrict: 'A',
terminal: true,
transclude: false,
scope:{
afterRender:"&"
},
link: function (scope, element, attrs) {
console.log(scope.afterRender);
}
};
return def;}]);
In this case, angular will interpret attribute as a function.
in html
after-render="mai.callback()"

How to make a template repeat

I have a directive, I want that template to show all the rows from data set
app.directive('exampleDirective', [ 'TestProvider', 'TestFactory', function (TestProvider, TestFactory) {
return {
restrict: 'E',
template: '<tr><td>{{Name}} </td><td>{{Surname}}</td></tr>',
replace: true,
link: function(scope, elm, attrs) {
var dat= TestFactory.dataReturn();
for (var i = 0; i < dat.length; i++) {
scope.Name = dat[i].Name;
scope.Surname = dat[i].Surname;
console.log(dat[i]);
}
// alert("hah");
}
};
}]);
How can I make it repeat like ng-repeat ?
Assuming your service returning a promise. Here is the simple code to repeat your data in table.
app.directive('exampleDirective', [ 'TestProvider', 'TestFactory', function (TestProvider, TestFactory) {
return {
restrict: 'E',
template: '<table ng-repeat="person in persons"><tr><td>{{person.Name }} </td><td>{{person.Surname}}</td></tr></table>',
replace: true,
link: function(scope, elm, attrs) {
TestFactory.dataReturn().then(function(resp){
scope.persons = resp.data;
});
}
};
}]);
Alternatively, you could redefine your element directive to represent a single object, and then ng-repeat the directive itself. Obviously, this would require moving the location where you use the factory. Your application architecture may or may not be able to accommodate this change.
directive:
app.directive('exampleDirective', [function () {
return {
restrict: 'E',
template: '<tr><td>{{person.Name}} </td><td>{{person.Surname}}</td></tr>',
replace: true,
scope: {
person: '='
}
};
}]);
And usage:
<example-directive ng-repeat="data in dataFromFactory" person="data"></example-directive>

AngularJS : Change parent scope value from custom directive

For some reason I can't make this work based on the other examples I've seen here on SO.
Here's my directive:
(function () {
angular.module('materialDesign')
.directive('aSwitch', directive);
function directive() {
return {
templateUrl: 'elements/material/switch/switch.html',
transclude: false, // I've tried true here
restrict: 'E',
scope: {
enabled: '=',
toggleState: '=',
},
link: function(scope, element) {
element.on('click touchstart', function() {
scope.toggleState = !scope.toggleState;
});
}
};
}
})();
And the controller scope value that I want to change when toggling the switch/checkbox:
$scope.hideInactive = true;
The html:
<a-switch toggle-state="hideInactive"></a-switch>
and further down in my html page, I have this:
<div ng-show="!hideInactive">
<!-- stuff -->
</div>
EDIT:
This version is "working now", but as soon as I click my switch/checkbox a second time, the element.on fires twice, this flipping my scope value back to what it was.....basically, it's not letting me "un-check" my toggle.
angular.module('material')
.directive('aSwitch', [
'$timeout', function($timeout) {
return {
templateUrl: 'elements/material/switch/switch.html',
transclude: false,
restrict: 'E',
scope: {
enabled: '=',
toggleState: '=',
},
link: function (scope, element) {
element.on('click touchstart', function () {
$timeout(function () {
scope.toggleState.state = !scope.toggleState.state;
scope.$apply();
});
});
}
};
}
]);
EDIT and FINAL SOLUTION:
Here's the updated directive link property that fixed everything. I'd like to add that Oleg Yudovich's answer was also used (passing an object as the property instead of a true/false by itself)
link: function (scope, element) {
element.on('click touchstart', function (event) {
if (event.srcElement && event.srcElement.id && event.srcElement.id === "switch") {
event.stopPropagation();
$timeout(function() {
scope.toggleState.state = !scope.toggleState.state;
});
}
});
}
Try to pass object instead of primitive variable like this:
$scope.hideInactive = {
state: false;
}
html without changes:
<a-switch toggle-state="hideInactive"></a-switch>
in your directive:
scope.toggleState.state = !scope.toggleState.state;
Reed this awesome article: https://github.com/angular/angular.js/wiki/Understanding-Scopes
You need to run digest cycle after changes in scope, because changing scope binding from event will not run angular digest cycle, you need to run it manually by doing scope.$apply()
Directive
(function () {
angular.module('materialDesign')
.directive('aSwitch', directive);
function directive($timeout) {
return {
templateUrl: 'elements/material/switch/switch.html',
transclude: false, // I've tried true here
restrict: 'E',
scope: {
enabled: '=',
toggleState: '=',
},
link: function(scope, element) {
element.on('click touchstart', function() {
$timeout(function(){
scope.toggleState = !scope.toggleState;
});
});
}
};
}
})();
Try below code:
angular.module('material').directive('aSwitch', ['$timeout', function($timeout) {
return {
templateUrl: 'elements/material/switch/switch.html',
transclude: false,
restrict: 'E',
scope: {
enabled: '=',
toggleState: '=',
},
link: function(scope, element) {
element.on('click touchstart', function() {
$timeout(function() {
scope.toggleState.state = !scope.toggleState.state;
scope.$apply();
});
});
}
};
}]);

Passing id and as a parameter to directive

http://jsfiddle.net/mato75/t48qn/
I have a directive, that if id is not passed, then it should generate one, but it looks like that the generation is to slow and the id is not present in the directive.
(function (angular) {
'use strict';
angular.module('Widgets.Module')
.directive('myDirective', [
function () {
function postLink(scope, jqElm, attr) { }
function postCompile(tElement, tAttrs) {
return function postLink(scope, jqElm, attr) {
attr.$observe("id", function (id) { // called on on init
scope.id = id !== undefined ? id : 'something 1';
});
}
}
function Ctrl(scope) {
}
return {
template:
'<div id="{{ id }}">' +
'</div>',
controller: [
'$scope', Ctrl
],
replace: true,
scope: {
id: '#'
},
restrict: 'AC',
link: postLink,
compile: postCompile
};
}
])
;
})(window.angular)
I think using id is special since its a valid DOM attribute. In my case id was also getting added as an attribute to the directive html, not the inner child where I was using it.
I created a new attribute called input-id that doesn't suffer from this name collision.
<autosuggest input-id="country"></autosuggest>
The produced markup is:
<div class="autosuggest"><input id="country"></div>
...which is what I think you are after.
The scope block for the directive looks like this:
scope: {
inputId: '#'
}
One possible solution is to disable the automatic data binding (scope: {}) and do it manually in your link function.
Check this fiddle.
module.directive('myDialog', function () {
return {
replace: true,
restrict: 'E',
scope: {},
template: '<div>Test {{a1}}</div>',
link: function (scope, element, attrs) {
if (!attrs.a1) {
scope.a1 = "default";
} else {
scope.a1 = attrs.a1;
}
}
}
});

AngularJS - accessing parent directive properties from child directives

This should not be too hard a thing to do but I cannot figure out how best to do it.
I have a parent directive, like so:
directive('editableFieldset', function () {
return {
restrict: 'E',
scope: {
model: '='
},
replace: true,
transclude: true,
template: '
<div class="editable-fieldset" ng-click="edit()">
<div ng-transclude></div>
...
</div>',
controller: ['$scope', function ($scope) {
$scope.edit = ->
$scope.editing = true
// ...
]
};
});
And a child directive:
.directive('editableString', function () {
return {
restrict: 'E',
replace: true,
template: function (element, attrs) {
'<div>
<label>' + attrs.label + '</label>
<p>{{ model.' + attrs.field + ' }}</p>
...
</div>'
},
require: '^editableFieldset'
};
});
How can I easily access the model and editing properties of the parent directive from the child directive? In my link function I have access to the parent scope - should I use $watch to watch these properties?
Put together, what I'd like to have is:
<editable-fieldset model="myModel">
<editable-string label="Some Property" field="property"></editable-string>
<editable-string label="Some Property" field="property"></editable-string>
</editable-fieldset>
The idea is to have a set of fields displayed by default. If clicked on, they become inputs and can be edited.
Taking inspiration from this SO post, I've got a working solution here in this plunker.
I had to change quite a bit. I opted to have an isolated scope on the editableString as well because it was easier to bind in the correct values to the template. Otherwise, you are going to have to use compile or another method (like $transclude service).
Here is the result:
JS:
var myApp = angular.module('myApp', []);
myApp.controller('Ctrl', function($scope) {
$scope.myModel = { property1: 'hello1', property2: 'hello2' }
});
myApp.directive('editableFieldset', function () {
return {
restrict: 'E',
scope: {
model: '='
},
transclude: true,
replace: true,
template: '<div class="editable-fieldset" ng-click="edit()"><div ng-transclude></div></div>',
link: function(scope, element) {
scope.edit = function() {
scope.editing = true;
}
},
controller: ['$scope', function($scope) {
this.getModel = function() {
return $scope.model;
}
}]
};
});
myApp.directive('editableString', function () {
return {
restrict: 'E',
replace: true,
scope: {
label: '#',
field: '#'
},
template: '<div><label>{{ label }}</label><p>{{ model[field] }}</p></div>',
require: '^editableFieldset',
link: function(scope, element, attrs, ctrl) {
scope.model = ctrl.getModel();
}
};
});
HTML:
<body ng-controller="Ctrl">
<h1>Hello Plunker!</h1>
<editable-fieldset model="myModel">
<editable-string label="Some Property1:" field="property1"></editable-string>
<editable-string label="Some Property2:" field="property2"></editable-string>
</editable-fieldset>
</body>
You can get access to parent controller by passing attribute in child directive link function
link: function (scope, element, attrs, parentCtrl) {
parentCtrl.$scope.editing = true;
}

How to add ngshow directive inside compile/link?

I want to add ngshow in the following custom element in a dynamic way... How to do that?
<toggler on-enable="main.enable()" on-disable="main.disable()">
<div style="width:100px;height:100px;background-color:#2fa">
<on>On state</on>
<off>Off state</off>
</div>
</toggler>
cf.directive('toggler', function () {
return {
restrict: 'AE',
scope: {
state: true,
onEnable: '&',
onDisable: '&'
},
compile: function (elem, attrs) {
var onElem = elem.find('on');
var offElem = elem.find('off');
// WANT TO DO THIS
// onElem.ngShow = 'state';
// offElem.ngShow = '!state';
}
};
});
You're doing it in the wrong way. Don't forget a rule of thumb in AngularJS: avoid DOM manipulation when it's not mandatory.
I guess that <on> and <off> are also custom directives, because you can't simply add tags without any defined behaviour. So, why don't put the ngShow attribute directly in this directives? Then, a directive's controller (see the documentation) will handle the communication between <on>/<off> and <toggler>:
myApp.directive('toggler', function () {
return {
restrict: 'AE',
scope: {
state: '=',
},
controller : [
'$scope',
function ($scope) {
this.isOn = function () {
return $scope.state;
};
},
],
};
});
myApp.directive('on', function () {
return {
restrict: 'AE',
require: '^toggler',
template: '<div ng-show="isOn()" ng-transclude />',
replace: true,
scope: true,
transclude: true,
link : function ($scope, element, attributes, togglerController) {
$scope.isOn = togglerController.isOn;
},
};
});
myApp.directive('off', function () {
return {
restrict: 'AE',
require: '^toggler',
template: '<div ng-hide="isOn()" ng-transclude />',
replace: true,
scope: true,
transclude: true,
link : function ($scope, element, attributes, togglerController) {
$scope.isOn = togglerController.isOn;
},
};
});
Fiddle
This way, you will be able to simply unit test your toggler, and extend his behaviour when needed.
