Issue
I am new at Angular.js. I am looking to do some dynamic table creation. I added some records helping with JSON Ang ng-model but how can I remove current record when click on remove button?
Passing with this operator:
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.emplist = [
{empname:'samudrala',empsalary:'4.5 - pam',empid:'Emp - 450'},
{empname:'soujanya',empsalary:'4.5 - pam',empid:'Emp - 451'},
{empname:'suguna',empsalary:'4.5 - pam',empid:'Emp - 452'},
{empname:'sangeetha',empsalary:'4.5 - pam',empid:'Emp - 453'},
{empname:'sadhanandham',empsalary:'4.5 - pam',empid:'Emp - 454'},
{empname:'jai',empsalary:'4.5 - pam',empid:'Emp - 455'},
{empname:'vijay',empsalary:'4.5 - pam',empid:'Emp - 456'},
{empname:'Ajay',empsalary:'4.5 - pam',empid:'Emp - 457'},
{empname:'Sandya',empsalary:'4.5 - pam',empid:'Emp - 458'},
{empname:'Raamu',empsalary:'4.5 - pam',empid:'Emp - 459'}
];
$scope.addItem = function(){
$scope.emplist.push({'empname':$scope.empname,'empsalary':$scope.empsalary,'empid':$scope.empid});
$scope.empname = '';
$scope.empsalary = '';
$scope.empid = '';
}
$scope.remItem = function(x){
$scope.emplist.splice(x,1);
}

<td style="padding:2px;"><input type="text" ng-model="empid" style="width:100%;" ></td>

</table>
</div>
</body>
</html>Solution
Instead of showing the table row for each record, use ng-repeat
<tr ng-repeat="emp in emplist">
<td>{{emp.name}}</td>
<td>{{emp.name}}</td>
<td>{{emp.name}}</td>
<td><button ng-click="remItem($index)">Remove</button></td>
And inside the controller directly you can get the $index
$scope.remItem = function(itemIndex){
$scope.emplist.splice(itemIndex,1);
}
