First of all, the way i am doing may not be correct. But i will explain the problem:
1) I am creating directive called as < firstDirective >
2) when the clicks on a button in the first directive, then I am trying to insert the second directive dynamically at runtime
As follows:
<!DOCTYPE html>
<html>
<script src="lib/angular/angular.js"></script>
<body ng-app="myApp">
<first-directive></first-directive>
<script>
var app = angular.module("myApp", []);
app.directive("firstDirective", function() {
return {
template : '<h1>This is first directive!</h1> <br / ><br / ><button type="button" ng-click="firstCtrl()">Click Me to second directive!</button> <div id="insertSecond"></div> ',
controller: function ($scope) {
$scope.firstCtrl = function($scope) {
angular.element(document.querySelector('#insertSecond')).append('<second-directive></second-directive>');
}
}
}
});
app.directive("secondDirective", function() {
return {
template : '<h1>This is second directive!</h1> <br / ><br / >',
controller: function ($scope) {
}
}
});
</body>
</html>
But it is not working, i mean, it is inserting the "< second-directive > < / second-directive >" text but not the content as per the directive above.
I am new to angular js, I think we can do this in a different way or my approach itself is not correct. But all i want to insert the second directive dynamically.
EDIT:: I got the solution for this, thanks to the George Lee:
Solution is we have to compile as follows, but didn’t pass scope object to the function:
<!DOCTYPE html>
<html>
<script src="lib/angular/angular.js"></script>
<body ng-app="myApp">
<first-directive></first-directive>
<script>
var app = angular.module("myApp", []);
app.directive("firstDirective", function($compile) {
return {
templateUrl : '<h1>This is first directive!</h1> <br / ><br / ><button type="button" ng-click="firstCtrl()">Click Me to second directive!</button> <div id="insertSecond"></div> ',
controller: function ($scope) {
$scope.firstCtrl = function() {
var ele = $compile('<second-directive></second-directive>')($scope);
angular.element(document.querySelector('#insertSecond')).append(ele);
}
}
}
});
app.directive("firstDirective", function() {
return {
templateUrl : '<h1>This is second directive!</h1> <br / ><br / >',
controller: function ($scope) {
}
}
});
Also, this link , gives very good explanation of how to dynamically compile and inject the templates.
You can use the $compile service in Angular, make sure you include it in the dependency injection.
app.directive("firstDirective", ['$compile', function($compile) {
...
controller: function ($scope) {
$scope.firstCtrl = function() {
var ele = $compile('<second-directive></second-directive>')($scope);
angular.element(document.querySelector('#insertSecond')).append(ele);
}
}
There is one more problem instead of templateUrl, template should be there
<!DOCTYPE html>
<html>
<script data-require="angular.js@1.0.x" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js" data-semver="1.0.8"></script>
<first-directive></first-directive>
<script>
var app = angular.module("myApp", []);
app.directive("firstDirective", function($compile) {
return {
template : '<h1>This is first directive!</h1> <br / ><br / ><button type="button" ng-click="firstCtrl()">Click Me to second directive!</button> <div id="insertSecond"></div> ',
controller: function ($scope) {
$scope.firstCtrl = function() {
var ele = $compile('<second-directive></second-directive>')($scope);
angular.element(document.querySelector('#insertSecond')).append(ele);
}
},
restrict: "EAC"
}
});
app.directive("secondDirective", function() {
return {
template : '<h1>This is second directive!</h1> <br / ><br / >',
controller: function ($scope) {
},
restrict: "EAC"
}
});
</script>
</body>
</html>
