How to Seamlessly Integrate Razor and JavaScript Code for Dynamic Functionality?

Mixing Razor and JavaScript Code

When working with Razor views, it's often necessary to integrate JavaScript code for dynamic functionality. However, one common challenge is mixing Razor and JavaScript code effectively.

Code Example

Consider the following code snippet:

<code class="csharp"><script type="text/javascript">
        var data = [];

        @foreach (var r in Model.rows)
        {
                data.push([ @r.UnixTime * 1000, @r.Value ]);
        }
</script></code>

In this example, the goal is to dynamically generate JavaScript data from the C# model. However, this code may not work as expected due to the way Razor interprets code blocks.

Solution: Using

To achieve this, we can use the element within Razor code blocks:

<code class="csharp"><script type="text/javascript">
   var data = [];

   @foreach (var r in Model.rows)
   {
      <text>
            data.push([ @r.UnixTime * 1000, @r.Value ]);
      </text>
   }
</script></code>

The element allows us to include literal JavaScript code within a Razor block. This way, the JavaScript code is treated as text and not executed by Razor.

When this code is rendered, it will generate the following JavaScript:

<code class="javascript">var data = [];

data.push([ @r.UnixTime * 1000, @r.Value ]);
data.push([ @r.UnixTime * 1000, @r.Value ]);
...</code>

This solution effectively mixes Razor and JavaScript code, allowing you to generate dynamic JavaScript data from your C# model.
