So I successfully displaying 1 database from my firebase using limitToLast function. Here is the webpage look like
Kinda curious how to display all of my databases (all childs from selected parent) from firebase console using javascript?
List of my database in firebase that I want to display
and here is my code below:
firebase.initializeApp(config);
var order = firebase.database().ref("order");
order.on("value", function(snapshot) {
console.log(snapshot.val());
}, function (error) {
console.log("Error: " + error.code);
});
var submitOrder = function () {
var orderId = $("#orderOrderId").val();
var shipping = $("#orderShipping").val();
var subtotal = $("#orderSubtotal").val();
var total = $("#orderTotal").val();
};
order.limitToLast(1).on('child_added', function(childSnapshot) {
order = childSnapshot.val();
$("#orderId").html(order.orderId)
$("#shipping").html(order.shipping)
$("#subtotal").html(order.subtotal)
$("#total").html(order.total)
$("#link").attr("https://wishywashy-179b9.firebaseio.com/", order.link)
});

You will need to generate a new <tr> for each order. A very simple way to do this is simply generate the DOM elements in your on('child_added' callback:
var table = document.querySelector("tbody");
order.on('child_added', function(childSnapshot) {
order = childSnapshot.val();
var tr = document.createElement('tr');
tr.appendChild(createCell(order.orderId));
tr.appendChild(createCell(order.shipping));
tr.appendChild(createCell(order.subTotal));
tr.appendChild(createCell(order.total));
table.appendChild(tr);
});
As you can see, this code creates a new <tr> for each child/order, and populates that with simple DOM methods. It then adds the new <tr> to the table.
This code uses a simple helper function to handle the repetitious creating of <td> elements with a text node in them:
function createCell(text) {
var td = document.createElement('td');
td.appendChild(document.createTextNode(text));
return td;
}

I would like to swap 2 columns in a table. Finally, I succeeded the change, but only the data. The attributes of the cell (style, id, class) didn't move. I tried to move attributes with jquery (i know, not an elegant method), but it was only symptomatic treatment. After clicking the data reload button, the attributes restored.
How can I change the columns order with all attributes?

Thx a lot
Simple way
You can bind colors to header name as:
$scope.styles = {
id: "yellow",
name: "pink"
};
and table will look like:
<tr ng-repeat="row in rows">
<td class="o1" ng-style="{'background-color':styles[mycol[0]]}">{{col(row, 0)}}</td>
<td class="o2" ng-style="{'background-color':styles[mycol[1]]}">{{col(row, 1)}}</td>
<td class="o3" style="background-color:green;">{{col(row, 2)}}</td>
<td class="o4" style="background-color:blue;">{{col(row, 3)}}</td>
</tr>
Once header value changes, colors will change too
Codepen DEMO
More complicated but generic
You can achieve it by replacing all table with directive (headers + data) and by using $compile rebuild all HTML table.
I am trying to represent some data taken from database in a table. I am using jersey as back-end and I have tested it in Postman that it works. The problem is I cannot display my data in the table in front-end, when I use AngularJS. It only shows me a blank table, without data at all. I am pretty new to AngularJS and I really want anyone of you to help me find the problem with my piece of code below.
list_main.js
angular.module('app', [])
.controller('ctrl', function($scope, $http){
$scope.bookList = [];
$scope.loadData = function(){
$http.get('http://localhost:8080/BookCommerce/webapi/list').then(function(data){
$scope.bookList = data;
console.log($scope.bookList);
})
}
$scope.loadData();
})

Please help me. Thank you!
Okay this is much better than the last time,
There's still some bits wrong with your JS - it should look like this :
// Code goes here
var baseUrl = "https://demo5019544.mockable.io/";
angular.module('app', [])
.controller('ctrl', function($scope, $http){
$scope.bookList = [];
$scope.loadData = function(){
$http.get(baseUrl + 'BookCommerce/webapi/list').then(function(data){
$scope.bookList = data.data;
})
}
})
I made a demo REST service at : https://demo5019544.mockable.io/BookCommerce/webapi/list
which produces the kind of output your web service should product, I tested the code with this web service and with the tweaks I made it worked -- Yay.
The last thing I'd do now is check that your web service is throwing out the same / similar output that my mock is producing.
I am creating a table using ng-repeat that display some tickets info. Currently in the column "Ticket No" I am adding href link (when user click on the "Ticket No" it will open new tab and the URL will take the ticket no as parameter.
This a plunker I've created so it can show functionality as described above http://plnkr.co/edit/GB8WWz?p=preview
The problem I have now is that the href link might vary and it depends on the account column value. So if my "account = foo" set the href link of the Ticket No to "http://myfoopage.foo/ticketid...etc". If my "account = boo" set the href link for the Ticket No to "http://myboopage.boo/ticketid...etc".
Any idea on how to approach that ?
scriptang.js
angular.module('plunker', ['ui.bootstrap']);
function ListCtrl($scope, $dialog) {
$scope.items = [
{ticket: '123', description: 'foo desc',account:'foo'},
{ticket: '111', description: 'boo desc',account:'boo'},
{ticket: '222', description: 'eco desc',account:'eco'}
];
}
// the dialog is injected in the specified controller
function EditCtrl($scope, item, dialog){
$scope.item = item;
$scope.save = function() {
dialog.close($scope.item);
};
$scope.close = function(){
dialog.close(undefined);
};
}

</tr>
</tbody>
</table>
</div>

Updated plnkr here, I've made use of the ng-attr directive in combination with a function that creates an url.
$scope.getUrl = function (item) {
var url = '';
if(item.account === 'foo')
url = 'http://mywebpage.foo';
else
url = 'http://mwebpage.boo';
url += '/ticketid='+item.ticket
return url;
}
I'm sure everyone has seen questions of a similar ilk, and trust me when I say I have read all of them in trying to find an answer. But alas without success. So here goes.
With the below code, why can I not get an alert?
I have an ASP.Net MVC4 Web API application with AngularJS thrown in. I have pared down the code as much as I can.
I know that my AngularJS setup is working correctly because on loading my view it correctly gets (via a Web API call) and displays data from the database into a table (the GetAllRisks function). Given that the Edit button is within the controller, I shouldn't have any scope issues.
NB: the dir-paginate directive and controls are taken from Michael Bromley's excellent post here.
I would appreciate any thoughts as my day has degenerated into banging my head against my desk.
Thanks,
Ash

you cannot use ng-click attribute on input with angularjs : https://docs.angularjs.org/api/ng/directive/input.
use onFocus javascript event
<input type="text" onfocus="myFunction()">
or try to surround your input with div or span and add ng-click on it.
I've got the working demo of your app, code (one-pager) is enclosed below, but here is the outline:
removed everything concerning dirPagination directive, replaced by ngRepeat
removed $log and replaced by console.log
since I don't have a Web API endpoint, I just populated $scope.Risks with some items on a rejected promise
Try adjusting your solution to first two items (of course, you won't populate it with demo data on rejected promise)

Thank you all for your help, particularly #FrailWords and #Dalibar. Unbelievably, this was an issue of caching old versions of the javascript files. Doh!
You can't directly use then on your service without resolving a promise inside it.
fiddle with fallback data
this.getAllRisks = function () {
var d = $q.defer();
$http.get('/api/RiskApi').then(function (data) {
d.resolve(data);
}, function (err) {
d.reject('no_data');
});
return d.promise;
}
This will also fix your problem with getting alert to work.
Hello I want to create simple search table of data.
I want to highlight if data matched user type input. I done it by doc below since I'm starting using angular i wonder is there any better way? Some custom filter maybe ?

You just need to custom filter like this:
$scope.customFilter = function(data, searchFor) {
if (angular.isUndefined(data) || angular.isUndefined(searchFor)) return data;
angular.forEach(data, function(item) {
if(angular.equals(item, searchFor)) item.highlighted = true;
});
return data;
}
and html like this
<tr ng-repeat="foo in data | customFilter:{something:1}" ng-class="{highlighted: foo.highlighted}">
Update:
So, I just need to explain my approach in more details. You have data some of which is needed to be highlighted. So you need to set new property in your data and highlight it (using css and ng-class) if property set to true.
For setting this property you can create custom filter that takes your data array, changes it internal state by setting this property and return this array as result. This is what I implemented for you.
Update#2
Same behaviour as ng-filter needed. So here it is.
