How to Iterate Over the Keys and Values with ng-repeat in AngularJS?

Are you struggling to iterate over the keys and values in a dictionary using ng-repeat in AngularJS? Don't worry, we've got you covered! In this blog post, we will address this common issue and provide you with easy solutions to help you display the keys and values in your AngularJS application.

The Problem

Let's start by looking at the problem in context. In your controller, you have a data object, $scope.object, which contains a dictionary with keys and values from a JSON file. You want to display both the keys and values in a table using ng-repeat in your template.

The Solution

To iterate over the keys and values in AngularJS, you can use the ng-repeat directive with the (key, value) syntax. Here's how you can do it:

1. In your HTML template, add the following code within the <table> element:

   <tr ng-repeat="(key, value) in object"> <td>{{ key }}</td> <td>{{ value }}</td> </tr>

2. In the above code, object refers to your data object. By using (key, value), you can access both the keys and values of the dictionary.

That's it! By following these simple steps, you can now iterate over the keys and values in your AngularJS application and display them in a table.

Example

To help you better understand how this works, let's consider the data object you provided:

{
    "id": 2,
    "project": "wewe2012",
    "date": "2013-02-26",
    "description": "ewew",
    "eet_no": "ewew"
}

Using the solution mentioned above, the HTML code will be rendered as follows:

<table>
   <tr>
     <td>id</td>
     <td>2</td>
   </tr>
   <tr>
     <td>project</td>
     <td>wewe2012</td>
   </tr>
   <tr>
     <td>date</td>
     <td>2013-02-26</td>
   </tr>
   <tr>
     <td>description</td>
     <td>ewew</td>
   </tr>
   <tr>
     <td>eet_no</td>
     <td>ewew</td>
   </tr>
</table>

As you can see, each key and its corresponding value are displayed in separate table cells.

Conclusion

The ng-repeat directive in AngularJS makes it easy to iterate over the keys and values in a dictionary. By following the simple steps outlined in this blog post, you can display both the keys and values in a table. Now you can confidently tackle this task in your AngularJS application!
