javascript css angularjs angularjs-ng-click ng-class

ng-class have class on first row of table and remove it on ng-click

I am using angular js to display a table. When the page loads I want the first row of the table to be highlighted, then when you click on another row of the table I want to remove the hightlighted class.

I've managed to get it to add the class on the top row using

 ng-class="{'selected-row':$first}"

but then I'm not able to remove it. I'd lke to be able to pass a variable from $scope, like this, so that I can change the value on click...

controller....

 $scope.changeClass = function(){
  if ($scope.myClass === "selected-row"){
    $scope.myClass = "off";
    window.alert('change class here to remove highlight!!!');
  } else {
    $scope.myClass = "selected-row";
    window.alert('change it back!!');
  }

html....

 <tr ng-repeat="row in $data" ng-click="changeClass()" ng-class="{myClass:$first}">

This doesn't work and I can't figure out the syntax (if it's possible!!) Any ideas?

Solution

You can use ng-class along with an array which keeps track of your row index to achieve this

// Code goes here
var app = angular.module('ngTableApp', ['ngTable'])
          .controller('selectFilterController', function($scope, $filter, $q, NgTableParams) {
            var data = [{name: "Moroni", age: 50},
                        {name: "Tiancum", age: 43},
                        {name: "Jacob", age: 27},
                        {name: "Nephi", age: 29},
                        {name: "Enos", age: 34},
                        {name: "Tiancum", age: 43},
                        {name: "Jacob", age: 27},
                        {name: "Nephi", age: 29},
                        {name: "Enos", age: 34},
                        {name: "Tiancum", age: 43},
                        {name: "Jacob", age: 27},
                        {name: "Nephi", age: 29},
                        {name: "Enos", age: 34},
                        {name: "Tiancum", age: 43},
                        {name: "Jacob", age: 27},
                        {name: "Nephi", age: 29},
                        {name: "Enos", age: 34}
                    ];


    $scope.class = "selected-row";
    $scope.changeClass = function(index){
     $scope.selected=[];  
     $scope.selected[index]=true;
    };
    $scope.changeClass(0); 
            $scope.names = [{id: "", title: ""}, {id: 'Moroni', title: 'Moroni'}, {id: 'Enos', title: 'Enos'}, {id: 'Nephi', title: 'Nephi'}];
            $scope.tableParams = new NgTableParams({page: 1, count: 10}, {data: data});
            
          })

/* Styles go here */
.selected-row{
  border:solid purple 3px;
}

.off{
  border:none;
}

.table-striped > tbody > tr:hover{
  border:solid purple 3px;
}

.table-striped > tbody > tr:active{
  border:solid purple 3px;
}


.table-striped > tbody > tr:focus{
  border:solid purple 3px;
}
