"Exploring the power of Knockout JS by utilizing the foreach loop to iterate through

I have an observableArray:

self.stats = ko.observableArray([
        {"DFTD" : new Stat("Defensive TD", "DFTD",0,20,0,self.playerGroups[1])},
         {"GL" : new Stat("Games Lost", "GL",0,16,0,self.playerGroups[2])},
          {"FGA" : new Stat("Field Goals ATT", "FGA",0,100,0,self.playerGroups[0])},

    ]);

and I am attempting to iterate through it with a foreach loop and then display the name property of the Stat objects, which is the first element in that object.

<tbody data-bind="foreach: stats" id="stat-sliders">
        <tr>
            <td><span data-bind="text: stats.Stat().name"></span></td>


 </tbody>

I am unsure if I am doing this correctly. As a beginner with knockout, I am seeking assistance. Can anyone help?

Answer №1

Check out the code snippet below that generates an array of football statistics, each containing a key field and a stat field. Utilizing the key field can result in quicker access to the data. However, if you prefer having the property serve as the key in an object, it would offer even faster indexing, although it would no longer be an array.

Take a look and see if this meets your requirements.

Answer №2

Avoid the need to re-enter stats. Be mindful that the span is linked to the model property within the array.

<tbody data-bind="foreach: stats" id="stat-sliders">
        <tr>
            <td><span data-bind="text: name"></span></td>
            <!--/*<td class="statsListItem">
                    </tr>
 </tbody>

Furthermore, it seems like Knockout doesn't handle keyed arrays optimally in this scenario.
