Using Razor within JavaScript

Using Razor within JavaScript: Solving the Marker Compilation Errors 😎

Have you ever wondered if it's possible to use Razor syntax within JavaScript in a view (.cshtml)? Well, look no further! In this blog post, we'll discuss a common issue when trying to add markers to a Google map using Razor within JavaScript and provide you with easy solutions to solve those pesky compilation errors.

The Problem: Compilation Errors Galore 😱

So, you're trying to add markers to a Google map using JavaScript, but you also want to utilize some Razor syntax to dynamically populate the marker information from your model. Something like this:

<script type="text/javascript">
    // Some JavaScript code here to display the map, etc.

    // Now add markers
    @foreach (var item in Model) {
        var markerLatLng = new google.maps.LatLng(@(Model.Latitude), @(Model.Longitude));
        var title = '@(Model.Title)';
        var description = '@(Model.Description)';
        var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>'

        // Rest of the marker code
    }
</script>

However, when you try to compile this code, you're greeted with a barrage of compilation errors. 😫

The Solution: Escaping Razor Syntax 🚀

Fear not! There's an easy solution to this problem. To successfully use Razor syntax within JavaScript, you simply need to escape the Razor code using the @Html.Raw() method. This method allows you to output raw HTML or JavaScript without any encoding.

Let's apply this solution to our marker code:

<script type="text/javascript">
    // Some JavaScript code here to display the map, etc.

    // Now add markers
    @foreach (var item in Model) {
        var markerLatLng = new google.maps.LatLng(@(Html.Raw(Model.Latitude)), @(Html.Raw(Model.Longitude)));
        var title = '@(Html.Raw(Model.Title))';
        var description = '@(Html.Raw(Model.Description))';
        var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>'

        // Rest of the marker code
    }
</script>

By applying Html.Raw() to our Razor expressions, we ensure that the JavaScript parser interprets them as pure JavaScript and avoids any compilation errors. 🎉
