I'm building my first AngularJS dynamic form, built based on information received from a JSON file using AngularJS directive.
Everything works, my issue is that the JSON code is getting displayed while the page is loaded - once the page is loaded the JSON code disappears.
Am I doing something wrong?
Check http://plnkr.co/edit/v4jOwuF6jmZfORlNbvIB?p=preview to see the behavior, click on "Stop"/"Start" multiple times to see the behavior.

Basically instead of adding the loaded template into the element then compiling it in place I just compile the string then insert the compiled element directly
element.append($compile(data)(scope));
Seems you can still see a delay but this might be the async loading of the template causing that, would need to debug in the network panel and do some profiling or logging to see exactly what's going on.
Edit
Made a fork of the plnkr to show one with the template inlined so there's no delay fetching it with $http http://plnkr.co/edit/Tnc3VOeI8cELDJDHYPTO?p=preview instead just grabbing it synchronously from the template cache and using ng-template in a script block to have it loaded in advance.

I have an angular.js app where the index.html looks something like with ng-app in the <html> tag
<html lang="en" ng-app="app">
<head></head>
<body>
<custom-navbar-directive></custom-navbar-directive> //angular js directive
<custom-loader></custom-loader>
<!-- To render components -->
<div ui-view ng-cloak></div>
</body>
</html>
I was following the steps in the single-spa angular.js guide. I removed the ng-app from <html> tag and added the following in my app.js
System.register([], function (_export) {
return {
execute: function () {
_export(
window.singleSpaAngularjs.default({
angular: angular,
mainAngularModule: "app",
uiRouter: true,
preserveGlobal: false,
})
);
},
};
});
Also I did the import map and singleSpa.registerApplication steps in the index.html
My issue is now the content is rendering but the <custom-navbar-directive> and <custom-loader> are missing. I added them inside the index.html since they are commonly used in each html template.
When I inspect and checked the rendered html I noticed that they are outside the loaded single spa angularjs app
<custom-navbar-directive></custom-navbar-directive>
<custom-loader></custom-loader>
<div id="single-spa-application:legacyAngularApp">
<div id="__single_spa_angular_1" class="ng-scope">
<!-- content -->
</div>
</div>
I guess since they are directives if those are inside the <div id="__single_spa_angular_1" class="ng-scope"> then it should render.
Any idea how to solve this?
Firstly, thanks to Stack Overflow community for continued support for both experts and newbie's like me. I have recently started with Full Stack Dev on Mean Stack.
Currently, I am trying to create a mock-up for required UI before I dive into backed development.
I am using an AngularJS controller to display the required contents in an accordion. The accordion body includes some text values, and angular materialistic switch buttons to change value of 3 different parameters in data values.
I referred here for switch buttons config: https://www.tutorialspoint.com/angular_material/angular_material_switches.htm, and was successfully able to replicate the same. Now that I am trying to integrate this into my original view, it seems like switch buttons are created without any errors but aren't visible. I probably have some angular controller issue, which maybe causing the problem.
Here is Codepen: https://codepen.io/shubhammakharia/pen/Ngpgje
HTML:
<div class="mycontainer" ng-controller="MainController" ng-cloak>
<div class="col-xs-12 col-sm-6">
....
<div layout="column" ng-cloak >
<md-switch ng-model="item.sfs" aria-label="SFS Switch">
SFS {{ data.switch1 }}
</md-switch>
<md-switch ng-model="item.BOPIS" aria-label="SBOPIS Switch" ng-true-value="'true'" ng-false-value="'false'" class="md-warn">
BOPIS (md-warn): {{ data.switch2 }}
</md-switch>
<md-switch ng-disabled="true" aria-label="BOSTS Switch" ng-model="item.BOSTS">
BOSTS (Disabled)
</md-switch>
</div>
</div>
var app = angular.module('ksStore', ['ui.bootstrap']);
app.controller('MainController',
function ($scope) {
$scope.items = [
{
name: "item1",
storeid:'1',
desc: "DSW Easton",
phone:'+1-123-456-7890',
address:'Easton, Columbus, OH',
SFS: true,
BOPIS: false,
BOSTS: true
}
];
$scope.default = $scope.items[0];
$scope.message = 'false';
$scope.onChange = function(state) {
$scope.message = state;
};
});
app.controller('ItemController', ['$scope', function (scope) {
scope.$parent.isopen = (scope.$parent.default === scope.item);
scope.$watch('isopen', function (newvalue, oldvalue, scope) {
scope.$parent.isopen = newvalue;
});
}]);
The order of the script elements matter. You have to put bootstrap script after angular script element.

it is not displaying my message. controller.js file is not accessable
Its clear that you are trying to define a controller like a simple js function.
But, It works in a different way.
You have to initialize an angular app within an java-script variable like this,
var app=angular.module("MyApp");
and handle that entire angular application, through that js variable "app".
I strongly recommend you to completely go through below tutorials.. Then, Start creating the App..
https://www.tutorialspoint.com/angularjs/angularjs_mvc_architecture.htm
http://www.w3schools.com/angular/default.asp
You have to define your angular application and its modules.
var app = angular.module('myApp');
app.controller('serviceController', function() {
$scope.message = "Nice, I now know how to create an angular app";
})
And you will now be able to access it on your page:
<body ng-app="myApp">...
<div ng-controller="serviceController">...
{{message}}
This should help you since you're getting started with angular.
Here this example
define your controller name (controller.js)
var app = angular.module('myApp', []);
app.controller('ServicesCtrl', function($scope) {
$scope.message = "Hello";
});
define your app name (index.html)
<body ng-app="myApp">
<div class="container" ng-controller="ServicesCtrl">
<h1>Service Client Maker</h1>
{{message}}
</div>
</body>
I have a very simple form using angularjs that validates a number field test.html ...
http://plnkr.co/edit/mfxdTxGUXLZswzl1nyF2?p=preview
<div ng-app="myApp">
<script>
angular.module('myApp', [])
.controller('myController', ['$scope', function($scope) { }]);
</script>
<form name="myForm" ng-controller="myController">
<input name="numberField" ng-model="myModel" type="number" value="" />
<p ng-show="myForm.numberField.$error.number">Not valid number!</p>
</form>
</div>
</html>
I want to put that form into a different html page...
<html>
<div id="test">
<!--I want my angular js number element to go here-->
</div>
</html>
Normally when I do something like this I use javascript and make a request to the page and use innerhtml to place the form where i want it, something like this...
<script>
var xRequest1;
xRequest1=new XMLHttpRequest();
xRequest1.onreadystatechange=function ()
{
if((xRequest1.readyState==4) && (xRequest1.status==200))
{
document.getElementById("test").innerHTML=xRequest1.responseText;
}
}
xRequest1.open("post","test.html",true);
xRequest1.send();
</script>
However this is not working, any idea how I can do this? or is this even possible? Ive never worked with angularjs before. Thanks in advance!
If you are building angular app from scratch then, you should
consider, putting ng-app in the main index and using ng-include as
#Ronnie pointed out.
But, If you are forced to integrate angular, in one place on legacy
code, you can manually bootstrap angular app, after, filling the
div#test in the ajax callback using angular.boostrap :
Here is a working demo using your exemple.
var xRequest1;
xRequest1=new XMLHttpRequest();
xRequest1.onreadystatechange=function ()
{
if((xRequest1.readyState==4) && (xRequest1.status==200))
{
document.getElementById("test").innerHTML=xRequest1.responseText;
// bootstrap your app here ...
angular.bootstrap(document.getElementById('test'), ['myApp']);
}
}
xRequest1.open("get","test.html",true);
xRequest1.send();
I am trying to learn about angular Directives and following the example given in here (http://docs.angularjs.org/guide/directive), have written the below code. Could anyone please guide me as what am i doing wrong that the data from the scope of the controller is not being read in the directive? The site says nothing about it! And there is no error upon executing the code, it just does not display any data. Please help.
//My Html
<!DOCTYPE html>
<html data-ng-app="MyApp">
<head>
<title>Angular Directives</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body >
<div data-ng-controller = "MyCtrl"></div>
<div data-template-expanding-directive></div>
<script src="lib/angular.js"></script>
<script src="js/templateExpandingDirective.js"></script>
</body>
</html>
//My JS
'use strict';
var myapp = angular.module('MyApp',[]);
myapp.controller('MyCtrl',['$scope',function($scope){
$scope.customer = {
name: "Jenny",
place: "England"
};
}])
.directive('templateExpandingDirective',function(){
return {
template: 'Name: {{customer.name}}'
};
});
Regards
The directive is currently out of controller scope. So you need to have directive inside the controller scope. The html should be like this -
<div data-ng-controller = "MyCtrl">
<div data-template-expanding-directive></div>
</div>
If you do not move the directive element inside the controller div element then you can either have one more parent 'div' element or access the data from global root scope.
