AngularJS - Building a dynamic table based on a json

Question

Given a json like this:

{
   "name": "john"
   "colours": [{"id": 1, "name": "green"},{"id": 2, "name": "blue"}]
}

and two regular html inputs:

<input type="text" name="name" />
<input type="text" name="color" />
<input type="submit" value="submit" />

I need to build a table with all the possible variations, ex:

John green
John blue

That means that if a user continues adding values through the inputs new rows will appear building the new variations, for instance:

I also need to have available the id to handle it, and I need that when I add new values using the inputs for instance: "Peter" "Black", I need to autofill the id (colour id) dynamically like an auto increment in mysql, resulting in something like this:

{
  "colours": […...{"id": 3, "name": "black"}]
}

Is that possible? Which options do I have for doing that with angular? I'm still thinking in the jQuery way and I would like to do it in the angular way.

I took a look to hg-repeat, and used it, but I'm not figuring out how to deliver the expected result, the only thing that come to my mind was to use nested ng-repeats, but it didm´t work.

Thanks so much in advance,

Guillermo

Answer 1

Just want to share with what I used so far to save your time.

Here are examples of hard-coded headers and dynamic headers (in case if don't care about data structure). In both cases I wrote some simple directive: customSort

customSort

.directive("customSort", function() {
    return {
        restrict: 'A',
        transclude: true,    
        scope: {
          order: '=',
          sort: '='
        },
        template : 
          ' <a ng-click="sort_by(order)" style="color: #555555;">'+
          '    <span ng-transclude></span>'+
          '    <i ng-class="selectedCls(order)"></i>'+
          '</a>',
        link: function(scope) {

        // change sorting order
        scope.sort_by = function(newSortingOrder) {       
            var sort = scope.sort;

            if (sort.sortingOrder == newSortingOrder){
                sort.reverse = !sort.reverse;
            }                    

            sort.sortingOrder = newSortingOrder;        
        };


        scope.selectedCls = function(column) {
            if(column == scope.sort.sortingOrder){
                return ('icon-chevron-' + ((scope.sort.reverse) ? 'down' : 'up'));
            }
            else{            
                return'icon-sort' 
            } 
        };      
      }// end link
    }
    });

[1st option with static headers]

I used single ng-repeat

This is a good example in Fiddle (Notice, there is no jQuery library!)

           <tbody>
                <tr ng-repeat="item in pagedItems[currentPage] | orderBy:sortingOrder:reverse">
                    <td>{{item.id}}</td>
                    <td>{{item.name}}</td>
                    <td>{{item.description}}</td>
                    <td>{{item.field3}}</td>
                    <td>{{item.field4}}</td>
                    <td>{{item.field5}}</td>
                </tr>
            </tbody>

HTML

<table class="table table-striped table-condensed table-hover">
            <thead>
                <tr>
                   <th ng-repeat="header in table_headers"  
                     class="{{header.name}}" custom-sort order="header.name" sort="sort"
                    >{{ header.name }}

                        </th> 
                  </tr>
            </thead>
            <tfoot>
                <td colspan="6">
                    <div class="pagination pull-right">

                            <li ng-repeat="n in range(pagedItems.length, currentPage, currentPage + gap) "
                                ng-class="{active: n == currentPage}"
                            ng-click="setPage()">

                            <li ng-class="{disabled: (currentPage) == pagedItems.length - 1}">

                            </li>
                        </ul>
                    </div>
                </td>
            </tfoot>
            <pre>pagedItems.length: {{pagedItems.length|json}}</pre>
            <pre>currentPage: {{currentPage|json}}</pre>
            <pre>currentPage: {{sort|json}}</pre>
            <tbody>

                <tr ng-repeat="item in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
                     <td ng-repeat="val in item" ng-bind-html-unsafe="item[table_headers[$index].name]"></td>
                </tr>
            </tbody>
        </table>

As a side note:

The ng-bind-html-unsafe is deprecated, so I used it only for Demo (2nd example). You welcome to edit.

Answer 2

Here's an example of one with dynamic columns and rows with angularJS: http://plnkr.co/edit/0fsRUp?p=preview

Answer 3

TGrid is another option that people don't usually find in a google search. If the other grids you find don't suit your needs, you can give it a try, its free

Answer 4

Check out this angular-table directive.

<table class="table table-striped table-condensed table-hover">
    <thead>
    <tr>
        <th ng-repeat="header in headers | filter:headerFilter | orderBy:headerOrder" width="{{header.width}}">{{header.label}}</th>

    </thead>
    <tbody>
    <tr ng-repeat="user in users" ng-class-odd="'trOdd'" ng-class-even="'trEven'" ng-dblclick="rowDoubleClicked(user)">
