How to save all rows of a dynamic table in AngularJS?

I am trying to add the rows dynamically for one of the variables which is of type String array in my db. But it only saves the last value entered in the row rather than saving all of them in an array. Below is my view code:
<div class="row" ng-class='{red:true}'>
<label for="remedy">Remedy</label>
</div>
<input name="remedy" id="remedy" ng-model="error.remedy" required>
<br/>
<div class="row" ng-class='{red:true}'>
<a href="#!/errorcreate" class="btn btn-primary btn-small" ng-click="addRemedyRow()" ng-class='{red:true}'>Add Row</a></div>
<br/>
<table style="width:100%">
<thead>
<tr>
<th ng-class='{red:true}'>Remedy</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="rowContent in remedyrows">
<td>{{rowContent.remedy}}</td>
</tr>
</tbody>
</table>
{{error.remedy}}
<button type="submit" class="btn btn-default">Create</button>
Cancel
And this is the code in javascript:
$scope.remedyrows = [];
$scope.addRemedyRow = function() {
$scope.remedyrows.push({
remedy: $scope.error.remedy
});
Below is the output I am receiving (in a screenshot):
I added dsdfg as second row and my final error.remedy value just shows dsdfg rather than showing an array of both values : [wdssdsd,dsdfg]. error is the main document of which remedy is one of the fields of type String array.
Any ideas on how to achieve this?

Instead of error.remedy, which is used as holder for future remedyrow, use intermediate variable output for displaying results and sending them to the server:
Javascript:
$scope.output = $scope.remedyrows.map(function(x) { return x.remedy; });
$http({data: $scope.output, method: 'POST', url: url});
HTML:
{{output | json}}

you could have achieved it by following way:
$scope.remedyrows = [];
$scope.output;
$scope.addRemedyRow = function() {
$scope.remedyrows.push({
remedy: $scope.error.remedy
});
$scope.output = $scope.remedyrows.toString();
}
and in html
{{output}}

Angular Show Password after click

I have an inventory page that also contains a password field.
I would like to hide the password when the page is loaded, best would be to have points displayed **** and after click password is shown or a pop up.
JS
var get_cert = function () {
$http.get($scope.url.cert_list).then(
function (response) {
$scope.certs = response.data;
}
);
}
// execute get function
get_cert();
HTML
<div class="panel panel-default">
<table class="table table-striped valign_middle">
<tr class="table_header">
<td>Name</td>
<td>Pass</td>
</tr>
<tr ng-repeat="cert in certs | filter:search | orderBy:['name']">
<td>{{cert.name}}</td>
<td>
<button class="w3-btn w3-black w3-hover-green w3-ripple" ng-click="get_cert()">Show</button>
<span ng-show="get_cert()">{{cert.password}}</span>
</td>
</tr>
</table>

<button ng-show="!cert.showPw" class="w3-btn w3-black w3-hover-green w3-ripple" ng-click="cert.showPw = true">Show</button>
<span ng-show="cert.showPw">{{cert.password}}</span>
You can use ng-click to do cert.showPw = true, which will append a property called showPw (a boolean) to the object. Combined with ng-show, you can easily switch between the two.
This way you'll keep your controller free of any additional logic needed. You may include ng-click on the span which holds the password which will set showPw = false to switch it back to a button.
See my JSFiddle for full example.

Create a input
<input type="password" name="???">
Then you can change its type to "text" with
$("#idOfInout")type = 'text';

Dynamically adding HTML via javascript

Good Day,
I have an ASP.NET MVC app that I'm working on and have a partial view with one row of data.
<div class="row paymentRow">
<div class="col-xs-4">Additional Invoices</div>
<div class="col-xs-8"><input type="text" style="width: 100%"/></div>
</div>
I have a button that when clicked, it adds additional rows to the DOM after the after the last div with the class "row paymentRow".
<div class="btn-group" role="group" aria-label="...">
<button type="button" id="Add">Add Row</button>
<button type="button" id="Ok">Ok</button>
<button type="button" id="Cancel">Cancel</button>
</div>
The jQuery to add the additional row works:
$(function() {
$("#Add").click(function(e) {
e.preventDefault();
var row = '<div class="row paymentRow">' +
'<div class="col-xs-4"> </div>' +
'<div class="col-xs-8"><input type="text" style="width: 100%"/></div>' +
'</div>';
$("div.modalUploadWidth div.row:last").after(row);
});
});
My question is:
Is there a cleaner way to represent the HTML that is being dynamically constructed and assigned to row? I'm not a big fan of magic strings like this. Not only that, but there will be multiple instances of where I need to inject javascript into the DOM.
I know that I can put the string into a Resource and access it from there. I also know that Handlebars can do this by storing the javascript template into an external file and binding the contents of the external file to the DOM.
I'm trying to find alternatives I may be overlooking.
TIA,
coson

Client side binding library like KnockOut JS would be more appropriate to make dynamic controls on client side. Here goes a simple Knockout JS Sample - https://dotnetfiddle.net/fmwTtJ
<!DOCTYPE html>
<html lang="en">
<head>
<!-- JS includes -->
<script src="//code.jquery.com/jquery-2.1.4.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script src="//ajax.aspnetcdn.com/ajax/knockout/knockout-3.1.0.js"></script>
</head>
<table>
<thead>
<tr>
<th>Last Name</th>
<th>First Name</th>
</tr>
</thead>
<tbody data-bind="foreach: persons">
<tr>
<td><input data-bind="value: LastName"/></td>
<td><input data-bind="value: FirstName"/></td>
</tr>
</tbody>
</table>
<button data-bind="click: $root.addPerson ">Click</button>
<script>
var ViewModel = function() {
var self = this;
self.persons = ko.observableArray([]);
self.addPerson = function(){
self.persons.push(new Person('Last Name','First Name'));
};
}
var Person = function(lastName, firstName) {
var self = this;
self.LastName = ko.observable(lastName);
self.FirstName = ko.observable(firstName);
};
vm = new ViewModel()
ko.applyBindings(vm);
</script>
</html>
When you click on the button, it will add a new row -

//take existing row (you've said there is always at least one row)
$(".paymentRow").
//take last (maybe there s already more than one)
last().
// create deep copy
clone().
//append it as last element to the parent element
appendTo(".modalUploadWidth");

why after creation JavaScript objects they are being removed?

I want to add DOM object into my html, but after adding they are being removed immediately.
Could someone please help to debug below presented code?
function addVertex () {
var iTr = document.createElement('tr');
var jTr = document.createElement('tr');
iTr.id = 'block';
iTr.className = 'block';
jTr.className = 'block_2';
iTr.appendChild(jTr);
document.getElementById('vertex_table').appendChild(iTr);
}
<form>
<table>
<tbody id="vertex_table">
<tr>
<td>Vertex start</td>
<td>Vertex end</td>
<td>Weight</td>
</tr>
</tbody>
</table>
<input type="submit" value="Add Vertex" onclick="addVertex()"/>
</form>

The problem is that the form is submitted when you click button with type="submit". This causes page reload. I assume that in your case you don't actually need to send form. So change button type to button and it will work:
<input type="button" value="Add Vertex" onclick="addVertex()" />

Ng-init if array not yet created

I'm trying to build a template for a application and want to display a dynamic list with names. so i got this code to show the list and add/remove rows;
<table ng-init="page.businessRows = []">
<thead>
<tr>
<th>Company</th>
<th>Contact</th>
<th>Phone</th>
</tr>
</thead>
<tr ng-repeat="row in page.businessRows">
<td>
<input type="text" ng-model="row.name" />
</td>
<td>
<input type="text" ng-model="row.contact" />
</td>
<td>
<input type="text" ng-model="row.phone" />
</td>
<td>
<button ng-click="page.businessRows.splice($index,1)">
Remove
</button>
</td>
</tr>
</table>
<button class="btn" ng-click="page.businessRows.push({})">addRow</button>
the thing as that when this template is loaded page.busnessRows will most likely be loaded with rows so i want to change the ng-init to only create the empty array if businessRows is not initialised.
I have tried ng-init="page.businessRows = page.businessRows.length < 1 ? [] : page.businessRows but it did not work. How am i inteded to do conditions in jsangular expressions?
All help appreciated. Thanks in advance

You can do this instead:
<table ng-init="page.businessRows = page.businessRows || []">
Update
I look at the parser code of AngularJS and notice that version 1.2 (currently RC) supports ternary expression. So if you use AngularJS 1.2, this will also work (although more verbose than the above code):
<table ng-init="page.businessRows = page.businessRows == null ? [] : page.businessRows">
See demo here.
However, your original code might not work if page.businessRows is null, because the parser will fail to dereference length property of null. So just be careful there.

I don't think the ng-init will evaluate conditional statements properly. But you could refactor the condition into a controller function and call the function from ng-init.
<table ng-init="initializeBusinessRows(page.businessRows)">
The just put your conditional evaluation in the function on the controller scope.

I think you're trying to solve the wrong problem.
The problem is that you're allowing an action to occur before the data is loaded or ready. A secondary problem is you're using an expression in an ng-click where a scope function or controller function should be.
So...
Disable that button if the form isn't ready.
Use your controller to control these interactions.
So here's an example of the controller. The $timeout was added to simulate a delayed load of data into your $scope.page variable.
app.controller('MyCtrl', function($scope, $timeout, $window) {
//Timeout to simulate the asynchronous load
//of the page object on the $scope
$timeout(function(){
$scope.page = {
businessRows: []
};
}, 2000);
//scope method to add a row.
$scope.addRow = function (){
//for safety's sake, check to see if the businessRows array is there.
if($scope.page && angular.isArray($scope.page.businessRows)) {
$scope.page.businessRows.push({});
}
};
//scope method to remove a row
$scope.removeRow = function(index, row) {
if($window.confirm('Are you sure you want to delete this row?')) {
$scope.page.businessRows.splice(index, 1);
}
};
});
... and the HTML view (notice the ng-disabled and the ng-click) (and lack of ng-init):
<div ng-controller="MyCtrl">
<table>
<thead>
<tr>
<th>Company</th>
<th>Contact</th>
<th>Phone</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in page.businessRows">
<td>
<input type="text" ng-model="row.name" />
</td>
<td>
<input type="text" ng-model="row.contact" />
</td>
<td>
<input type="text" ng-model="row.phone" />
</td>
<td>
<button ng-click="removeRow($index, row)">
Remove
</button>
</td>
</tr>
</tbody>
</table>
<button class="btn" ng-disabled="!page" ng-click="addRow()">addRow</button>
</div>
Also, here's the obligatory Plunker for you to see this in action.
