dynamic table row generation using ng-repeat - javascript

my problem is similar to thread
Dynamic table creation with ng-repeat in angularjs
JSON looks like this
{
"id": "String",
"marks" :
{
"nummin":"integer"
"nummax":"integer"
"subjectname": "string",
}
}
Just there will be an additional feature user is going to enter no of rows which need to be generated and then the table will be generated according to dynamic JSON file which will be fetched from the database. Thanks in advance

Try out this JS-Fiddle.
Let me know if this helped you!
let app = angular.module('app', []);
app.controller('ctrl', ['$scope', ($scope) => {
$scope.numberOfRows = 0;
$scope.data = [];
$scope.$watch('data', () => {
console.log($scope.data);
}, true);
}]);
app.filter('range', function () {
return function (input, total) {
total = parseInt(total, 10);
for (let i = 0; i < total; i++) {
input.push(i);
}
return input;
};
});
<div ng-app="app">
<div ng-controller="ctrl">
<input type="number" ng-model="numberOfRows" />
<br />
<table width="100%">
<tr>
<th>nummin</th><th>nummax</th><th>...</th>
</tr>
<tr ng-repeat="i in [] | range:numberOfRows">
<td>
<input type="number" ng-model="data[i].nummin" />
</td>
<td>
<input type="number" ng-model="data[i].nummax" />
</td>
<td>...</td>

Can't call controller function from view

I want to call the controller function from view.
This my view:

As you can see in the view I have called the postdata function of the controller.This function internally uses msg variable.But view is not printing value of this variable.I am very new to Aj. Please help.
You need to make following changes:
Remove ng-controller="Allocation as vm", as you already defined controller above., and you not using this syntax in controller.
after you removed as vm, then no need to vm. calls.
you need to inject $http in your controller., to make API call
See this fiddle demo, I logged dummy text in console for each `submit click.
and to make single call on submit, See this Fiddle
You should return a value in the function or add a scope variable to be shown in the controller's div, because right now you are not showing anything.
<div ng-controller="Allocation as vm">
<div>{{vm.postdata(data.date)}}</div>
<p>Output Message : {{msg}}</p>
<p>StatusCode: {{statusval}}</p>
<p>Status: {{statustext}} </p>
<p>Response Headers: {{headers}} </p>
</div>
Anyway, you should not run procedural function in this way. Bind it to an event, ng-click or something.
And do not create other than td or th child elements in tr.
This is the proper html table structure:
<table>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
</table>

This line is reason of malfunctioning. You don't have any "table" controller. You bind repos in your mainController. Remove the "table" controller from that div, everything will work!

ng-repeat and ng-scrollbar doesn't work together

I'm just starting Angular JS and trying to have a scrollbar appearing as I add an element in the list which would be populated in the box of the contents.
I installed ng-scrollbar from here. https://github.com/asafdav/ng-scrollbar
HTML:
<link rel="stylesheet" href="../dist/ng-scrollbar.min.css" >
<style>
.scrollme {
max-height: 100px;
}
</style>
</head>
<body>
<div ng-app="DemoApp">
<div class="container" ng-controller="DemoController">
<table border="0" width="100%">
<div class="scrollme" ng-scrollbar rebuild-on="rebuild:me" is-bar-shown="barShown">
<tr>
<th width="2%"></th>
<th width="14%">Name</th>
<th width="85%">Address</th>
</tr>
<tr>
<td>
<img src="addImageButton.png" ng-click="addRow()" />
</td>
<td class="inlineBlock">
<input type="text" ng-model="row.name" />
</td>
<td>
<input ng-model="row.addr" />
</td>
</tr>
<tr ng-repeat="row in rowList">
<td>
<img src="removeImageButton.png"ng-click="removeRow($index)" />
</td>
<td>{{row.name}}</td>
<td>{{row.client}}</td>
</tr>
</div>
</table>
</div>
</div>
</body>
JavaScript:
(function () {
'use strict';
var app = angular.module('DemoApp', ['ngScrollbar']);
app.controller('DemoController', DemoController);
function DemoController($scope) {
// portfolio and broker tabs
$scope.row = {}
$scope.row.name = "";
$scope.row.addr = "";
$scope.rowList = [];
// adding a row to list
$scope.addRow = function() {
var data = {};
data.name = $scope.row.name;
data.addr = $scope.row.addr;
$scope.rowList.push(data);
$scope.row.name = "";
$scope.row.addr = "";
console.log($scope.rowList);
}
// removing a row from the list
$scope.removeRow = function(obj) {
console.log('end' + $scope.rowList);
if(obj != -1) {
$scope.rowList.splice(obj, 1);
}
}
$scope.$on('scrollbar.show', function(){
console.log('Scrollbar show');
});
$scope.$on('scrollbar.hide', function(){
console.log('Scrollbar hide');
});
// $scope.$on('loopLoded', function(evt, index) {
// if(index == $scope.me.length-1) {
// $scope.$broadcast('rebuild:me');
// }
// });
}
})();
It's part of my code so it might not fully make sense. But the way it works is that if I pressed the addImageButton, it would add a row which will add a row on the web. And conversely, removeImageButton will delete a row which will show on the web immediately. I need a scroll bar appearing once it reaches the height 100px. I checked the last answer of the ng-scrollbar is not working with ng-repeat
as well but it didn't work. Would be great if I could get some help with the detailed explanation. :) Thanks!
Figured out! I need to put the broadcast method in addRow and removeRow methods. Also, I had to put the out from the

Iterating over table using Angular

I'm new to angular and js. I did a table (just a header) and a button. When I click the button a new row line is added. Every cell of that row is a form text field. Everithing works fine. Now I'm trying to do a second button, when I click it must iterate over the rows and validate the fields. I'm not finding any documentation about that... so i'm not sure if this mettod (add a new row with a button) is appropiate. That's how I did it:
index.html this contains angular and my script, also contains the routes:
<html ng-app="assets">
<head>

assets.config(function($routeProvider) {
$routeProvider.
when('/', {
templateUrl: 'home.html'
}).
when('/:tipusactius', {
templateUrl: 'tipusactius.html',
controller: 'TipusActiusCtrl'
}).
when('/:tipusactius/alta', {
templateUrl: 'tipusactius-alta.html',

otherwise({

});
assets.controller('TipusActiusCtrl', function ($scope, $http){
$http.get('http://10.0.203.73/WS/ws.php/tipusactius/').success(function(data) {
$scope.tipus_actius = data;

I'm not sure if this has been a good idea. I would like to find a way to iterate over the rows to read cell values, and if the values of all cells from all the rows is ok submit the values to the web service but I have no idea. Any help will be great.
You don't actually need to manipulate html directly. Just use ng-repeat over your data collection. Button should add new items to that collection and angular will create new table row in the document.
I've created small sample here: http://jsfiddle.net/Lvc0u55v/252/
var myApp = angular.module('myApp', []);
myApp.controller('tableCtrl', function($scope) {
$scope.dataTable = [{
"name": "Alex",
"lastName": "Karlov",
"age": 23,
"sex": 1
}];
$scope.options = [{
"value": 1,
"title": "Male"
}, {
"value": 2,
"title": "Female"
}];
$scope.addRow = function() {
var newItem = {
name: "",
lastName: "",
age: "",
sex: ""
}
$scope.dataTable.push(newItem);
};
});
And this is the html (I've created it based on yours code):
<div class="col-md-8" ng-controller="tableCtrl">
<button ng-click="addRow()">Add row</button>
<div>
<table class="table">
<tr>
<td>#</td>
<td>Name</td>
<td>Last Name</td>
<td>Age</td>
<td>Sex</td>
</tr>
<tr ng-repeat="item in dataTable">
<td>{{ $index + 1 }}</td>
<td>
<input type="text" ng-model="item.name" />
</td>
<td>
<input type="text" ng-model="item.lastName" />
</td>
<td>
<input type="text" ng-model="item.age" />
</td>
<td>
<select ng-options="option.value as option.title for option in options" ng-model="item.sex"></select>
</td>
</tr>
</table>
</div>
</div>
In that sample I've put all my data into dataTable variable. When I want to add one more row, I just need to add new empty object (or with predefined values) into dataTable collection. Angular will do the trick.

Validating input using angularJS inside a function

My code is like this.
<form name="palletForm" novalidate=novalidate>

angular.module('myApp', []).controller('MainCtrl', ['$http', '$scope', function ($http, $scope) {
var counter = 0;
$scope.packageElement = [{

}];
$scope.newPackageItem = function (packageElement, $event) {
var npackageElement = {};
angular.copy(packageElement, npackageElement);
counter++;
packageElement.show = false;
npackageElement.name = counter;
angular.forEach(npackageElement.Data, function (row) {
if (row.PickQty != row.newquantity || row.PickQty != 0) {
row.PickQty = row.PickQty - row.newquantity;
row.SHPQTY = Number(row.SHPQTY) + Number(row.newquantity);
}
});
npackageElement.show = true;
angular.forEach(packageElement.Data, function (row) {
row.SHPQTY = Number(row.SHPQTY) + Number(row.newquantity);
});
$scope.packageElement.push(npackageElement);
};
}]);
Inside button click I am calling a function newPackageItem I want to validate my text boxes before that function executes. textbox is number only field and required. I want to validate it in angular way. How can I achieve this?
Fiddle
<body ng-app="phonecatApp">
<form ng-controller="PhoneListCtrl" name="myForm">
<p>
<input name="Quantity" ng-model="data.newquantity" placeholder="Quantity" required=required type="number" />
<span class="error" ng-show="myForm.Quantity.$error.pattern">
</span>
</p>
</form>
</body>
and in your javascript file
var phonecatApp = angular.module('phonecatApp', []);
phonecatApp.controller('PhoneListCtrl', function ($scope) {
$scope.pattern = /^[0-9]*$/;
});
