Attempting to populate the array within my script for future charting with D3.JS, I came across some issues. Following advice from this post, I used a specific syntax that unfortunately resulted in an error stating "Uncaught ReferenceError: WebSite is not defined." It appears this error stems from the namespace of the data being used (in this case, 'WebSite').
<script>
var data = new Array();
@foreach (var piece in @Model.DataPieces)
{
@:data.push(@piece);
}
</script>
The problem seemed related to the data type of `piece`, as tweaking the code slightly helped alleviate the errors. By individually extracting fields from the `piece` object and creating a new object to push into the array, the process worked more smoothly.
<script>
var data = new Array();
@foreach (var piece in @Model.DataPieces)
{
@:data.push({'cat': '@piece.Category', 'key': '@piece.Key', 'val': '@piece.Value'});
}
</script>
This manual approach, however, proves cumbersome, error-prone, and requires updates whenever the model changes. How can I automate the creation of JSON objects upon assignment, similar to the initial example?
The structure of the Razor page's viewmodel is outlined below.
namespace WebSite.Models
{
public class DrillDataViewModel
{
public List<DataPiece> DataPieces { get; set; }
public class DataPiece
{
public string Category { get; set; }
public string Key { get; set; }
public int Value { get; set; }
}
}
}
