How Can I Access MVC Model Properties in JavaScript?

Accessing MVC model properties in JavaScript

In MVC applications, models encapsulate domain logic and data, but accessing these properties from JavaScript can be difficult. One way is to convert the server-side model into a JavaScript object.

For example, consider the following server-side FloorPlanSettingsModel class:

<code class="language-csharp">public class FloorPlanSettingsModel
{
    public int Id { get; set; }
    public int? MainFloorPlanId { get; set; }
    public string ImageDirectory { get; set; }
    public string ThumbnailDirectory { get; set; }
    public string IconsDirectory { get; set; }
}</code>

To access one of these properties from JavaScript, follow this method:

<code class="language-javascript">var floorplanSettings = @Html.Raw(Json.Encode(Model.FloorPlanSettings));
alert(floorplanSettings.IconsDirectory);</code>

However, this may cause problems with complex models or circular references. To solve this problem, consider passing only specific properties to Json.Encode():

<code class="language-javascript">var floorplanSettings = @Html.Raw(Json.Encode(Model.FloorPlanSettings.IconsDirectory));</code>

This returns a serialized string representation of the attribute value, which can be accessed in JavaScript.
