I am a new to both jQuery EasyUI and AngularJs so I apologize in advance. I am trying a simple little app/page to use ng-repeat on a jQuery EasyUI Combobox to initialize its list of data. However, I am finding that the jQuery EasyUI is not being initialized properly. It seems as though a single option is added and ng-repeat is not being processed. (I tried the same thing using ng-option and had the same result).
Working index.html snippet:
<body ng-app="ExampleApp">
<div ng-controller="appController as appCtrl">
<select ng-model="appCtrl.mode">
<option ng-repeat="option in appCtrl.modeList" value="{{option.id}}">{{option.name}}</option>
</select>
<hr>
<tt>repeatSelect = {{appCtrl.mode}}</tt><br/>
</div>
</body>
app.js:
(function() {
var app = angular.module('ExampleApp', []);
app.controller('appController', ['$scope', function($scope) {
this.modeList = [{id: "1", name: 'Mode 1'},
{id: '2', name: 'Mode 2'} ];
this.mode = this.modeList[0].id;
}]);
})();
The code above works and the list has the initial data (modeList); however, if I add class="easyui-combobox" to the select statement it no longer works. In fact it displays {{option.name}} making me think Angular has not been processed yet. I suspect there is a simple solution but I am missing something. Any help/advice would be MUCH appreciated.

I'm having trouble trying to figure out how to fix a bug that happens when I try to push the same string as added previously to the array. It gets stuck and will not allow the app to post another string.
How do I make sure that your repeat doesn't get stuck when there two of the same values in the array?

--> Bug happens when I try to push "1"into the array again after a "1" is already posted.
HTML Code

<div data-ng-controller="appController" class="container">

<input data-ng-model = "input_data" type="text" id="status"/>
<button data-ng-click="add_data()"> OK </button>
<ul class = "list-group">
<li class="list-group-item" data-ng-repeat="x in array_data">

AngularJS code
var app = angular.module("myApp", []);
app.controller("appController", function ($scope) {
$scope.array_data = [];
$scope.add_data = function () {
$scope.array_data.push($scope.input_data);
};
$scope.remove_data = function (index) {
$scope.array_data.splice(index, 1);
};
});
You could use track by $index, example:
<li class="list-group-item" data-ng-repeat="x in array_data track by $index">
AngularJS tries by default to find a key in your array to index by. Normally this works well, but if you have duplicates then you have to tell AngularJS to make a new index, in this case, $index.
This code works:
<div ng-include src="'Test.html'"></div>
This code doesn't:
<div ng-include src="ctrl.URL"></div>
(ctrl.URL is set to "Test.html"). I also set it to 'Test.html' and "'Test.html'" with the same results.
How can I successfully convert this into an expression for use in ng-include src? I think I am missing some knowledge on how strings get parsed but I was pretty sure 'Test.html' should work.
I found that I am too incompetent to rename my own variables. ctrl.URL was really ctrl.URl. Now everything is working.
Check this, maybe this fiddle will help you.
HTML and templates:
<div ng-controller="Ctrl">
<select ng-model="template" ng-options="t.name for t in templates">
<option value="">(blank)</option>
</select>
url of the template: <tt>{{template.url}}</tt>
<hr/>
<div ng-include src="template.url" onload='myFunction()'></div>
</div>
<!-- template1.html -->
<script type="text/ng-template" id="template1.html">
Content of template1.html
</script>
<!-- template2.html -->
<script type="text/ng-template" id="template2.html">
<p ng-class="color">Content of template2.html</p>
</script>
The controller:
function Ctrl($scope) {
$scope.templates = [{
name: 'template1.html',
url: 'template1.html'},
{
name: 'template2.html',
url: 'template2.html'}];
$scope.template = $scope.templates[0];
$scope.myFunction = function() {
$scope.color = 'red';
}
}
I've got a page in my website in which I want to show a checkbox. I only want to show the checkbox if the model is initially false. So I wrote this (this was my initial code, but it was a simplified version of what I have myself. I updated the code in the snippet at the end of this question to show the problem):
<div ng-if="!the_field">
<input ng-model="the_field" type="checkbox">
</div>
The problem is that if I click the checkbox, it disappears. That of course makes sense, but I have no idea how to solve this.
So what I basically want is to show the checkbox if the model was false upon rendering the HTML. But after that I want to somehow break the databinding so that the checkbox remains on the page even if the model changes to true.
Does anybody know how I can achieve this? All tips are welcome!
[EDIT]
I would prefer doing this from within the template, so that I don't get a double list of these fields (because I've got about 50 of them). Any ideas?
[EDIT 2]
Turns out that it did work with the example above, which was a simplified version of my own code. In my own code however, I'm not using simple a field, but an item in a dict. I updated the code above and made a snippet below to show the problem:
var MainController = function($scope){
$scope.the_field = {};
$scope.the_field.item = false;
};
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="" ng-controller="MainController">
parent: {{the_field.item}}
<div ng-if="!the_field.item">
child: {{the_field.item}}<br>
<input ng-model="the_field.item" type="checkbox">
</div>
</div>
You can clone the source object. Like this:
angular.module('app', []).
controller('ctrl', function($scope) {
$scope.the_field = false;
$scope.the_field_clone = angular.copy($scope.the_field);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
{{the_field}}
<div ng-if="!the_field_clone">
<input ng-model="$parent.the_field" type="checkbox">
</div>
</div>

Update - option 2 - Directive
angular.module('app', []).
controller('ctrl', function($scope) {
$scope.the_field = false;
}).
directive('customIf', function() {
return {
scope: {
customIf: '='
},
link: function(scope, element, attrs) {
if (!scope.customIf) {
element.remove();
}
}
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
{{the_field}}
<div custom-if="!the_field">
<input ng-model="the_field" type="checkbox">
</div>
</div>
It works with the code of your question, try it out ;)
(see What are Scopes?)
var MainController = function($scope){
$scope.the_field = false;
};
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="" ng-controller="MainController">
parent: {{the_field}}
<div ng-if="!the_field">
child: {{the_field}}<br>
<input ng-model="the_field" type="checkbox">
</div>
</div>
The answer to your updated question:
You can use another property in your model, edited when the first click occurs...
var MainController = function($scope){
$scope.model = {init: true, the_field: false};
};
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="" ng-controller="MainController">
parent: {{model.the_field}}
<div ng-if="!model.the_field || !model.init">
<input ng-model="model.the_field" type="checkbox" ng-click="model.init=false;">
</div>
</div>
I currently have this site - http://dev.5874.co.uk/scd-data/ where I have a dropdown which displays results from WP-API which I am pulling in through AngularJS.
It currently combines the two sets of results as they're separate URL's, the results are in categories within a custom post type so if both posts are 'tagged' in the same category chosen they display twice. I need a way to combine the two sets of results but only showing one of the posts - I hope this makes sense. I'm very new to API data and AngularJS and I imagine there is a much simpler way of doing this. Any help would be much appreciated. Here is a snippet of my code to show how it's currently working.
Thanks in advance!

Here is a working code pen - http://codepen.io/anon/pen/yePYdq
Angular is a great JavaScript front-end framework to choose, and you're off to a good start, but a lot of changes could be made. I've made some suggested changes for easier ways to do things below.
See this CodePen for all changes.
It looks like you've grasped the idea of ng-repeat, but there's definitely a lot of repeated HTML and JS in your view and controller, so let's see if we can do better.
Let's try this without jQuery to avoid direct manipulation of the DOM. And instead of many controllers, we can do this with a single controller.
<div ng-app="MyApp">
<div ng-controller="MyController">
...
</div>
</div>
<script type="text/javascript">
var app = angular.module('MyApp', []);
app.controller('MyController', ...);
</script>
For the dropdown, we'll use ng-repeat in our view and display the names of the shooting types from our model
...
<select ng-model="selectedListing">
<option
ng-repeat="listingShootingType in listingShootingTypes"
value="{{listingShootingType.name}}">
{{listingShootingType.name}}
</option>
</select>
...
<script type="text/javascript">
...
// Our selections/filters
$scope.listingShootingTypes = [
'All',
'Air Rifle/Air Pistol',
'Clay',
'ABT',
'Double Trap',
'English Skeet',
'English Sporting',
'Fitasc',
'Olympic Skeet',
'Olympic Trap',
'Simulated Game',
'Sport Trap/Compact',
'Universal Trench',
'ZZ/Helice',
'Rifle',
'Centrefire Target Rifle',
'Gallery Rifle',
'Muzzle Loading',
'Practice Shotgun',
'Smallbore Rifle'
];
...
</script>
With only one controller, we can still use ng-repeat for each listing.
<div ng-repeat="d in data">
<h2 class="entry-title title-post">{{d.title}}</h2>
<div id="listing-image"><img src="{{d.acf.logo}}"></div>
<div id="listing-contact">Contact: {{d.acf.contact}}, {{d.acf.position}}</div>
<div id="listing-address-1">
{{d.acf.address_1}}, {{d.acf.address_2}} {{d.acf.address_3}} {{d.acf.town}} {{d.acf.county}} {{d.acf.postcode}}
</div>
<div id="listing-phone">Telephone: {{d.acf.telephone}}</div>
<div id="listing-mobile">Mobile: {{d.acf.mobile}}</div>
<div id="listing-email">Email: {{d.acf.email}}</div>
<div id="listing-website">Website: {{d.acf.website}}</div>
<div id="listing-established">Established: {{d.acf.established}}</div>
<div id="listing-about">About: {{d.acf.about}}</div>
<div id="listing-mailingaddress">Mailing Address: {{d.acf.mailing_address_}}, {{d.acf.mailing_address_2}}, {{d.acf.mailing_address_3}}, {{d.acf.mailing_town}}, {{d.acf.mailing_county}}, {{d.acf.mailing_postcode}}</div>
<div id="listing-directions">Directions: {{d.acf.directions}}</div>
<div id="scd-link">View on The Shooting Club Directory</div>
</div>
Finally... How do we only display listings that match our selected shooting type from the dropdown? We could use a custom Angular filter!
...
<div ng-repeat="d in data | filter:isSelectedListing">
...
<script type="text/javascript">
...
// Let's define a custom Angular filter because the WordPress JSON is complex
$scope.isSelectedListing = function(listing) {
// Show nothing if nothing is selected
if (angular.isUndefined($scope.selectedListing) || $scope.selectedListing == '') {
return false;
}
// Show all if 'All' is selected
if ($scope.selectedListing == 'All') {
return true;
}
// If the shooting type we're looking for is present, show the listing.
// To do this, we parse the WordPress JSON object model.
if (angular.isDefined(listing.terms.listing_shooting_type)) {
for (var i = 0; i < listing.terms.listing_shooting_type.length; i++) {
if (listing.terms.listing_shooting_type[i].name == $scope.selectedListing) {
return true;
}
}
}
return false;
};
...
</script>
Hopefully this gives you an idea of how we better leverage ng-repeat + DRY :)

Website address is http://bbn.kiwoom.com/bbn.corpAnalCRList.do (is not my site)
I want to get the webpage URL (pic 2) that you can move by clicking red box or calling js function(green box) like pic 1.
pic1&pic2
But the page URL doesn't change. I want to provide the page link(a tag) for other people at my website.
How to get the page URL (pic 2)? or Is there other solution for the page link(a tag) like using javascript function?
Thanks.
I think what you want, you can do easily with angular ng-include or object/iframe:
(function(angular) {
'use strict';
angular.module('includeExample', ['ngAnimate'])
.controller('ExampleController', ['$scope', function($scope) {
$scope.templates =
[ { name: 'pic1.html', url: 'https://www.google.com.br'},
{ name: 'pic2.html', url: 'http://www.google.com.br'} ];
$scope.template = $scope.templates[0];
}]);
})(window.angular);
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.0-beta.1/angular.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.0-beta.1/angular-animate.js"></script>
<body ng-app="includeExample">
<div ng-controller="ExampleController">
<select ng-model="template" ng-options="t.name for t in templates">
<option value="">(blank)</option>
</select>
url of the template: <code>{{template.url}}</code>
<hr/>
<div class="slide-animate-container">
<div class="slide-animate" ng-include="template.url"></div>
<object type="text/html" data="{{template.url}}"
style="width:100%; height:100%; margin:1%;">
</object>
</div>
</div>
</body>
(blank)
url of the template: {{template.url}}
https://docs.angularjs.org/api/ng/directive/ngInclude
You can use client routing - changing the url hash tag. Look at this small js library http://sammyjs.org/
You define your detail route, handling this route you will be showing your detail.
