[c#] Mix Razor and Javascript code

I'm pretty confused with how to mix razor and js. This is the current function I am stuck with:

<script type="text/javascript">

        var data = [];

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

If I could declare c# code with <c#></c#> and everything else was JS code -- this would be what I am after:

<script type="text/javascript">

        var data = [];

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

What is the best method to achieve this?

Inside a code block (eg, @foreach), you need to mark the markup (or, in this case, Javascript) with @: or the <text> tag.

Inside the markup contexts, you need to surround code with code blocks (@{ ... } or @if, ...)

you also can simply use

<script type="text/javascript">

   var data = [];

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

note @:

you can use the <text> tag for both cshtml code with javascript

Wrap your Razor code in @{ } when inside JS script and be aware of using just @ Sometimes it doesn't work:

function hideSurveyReminder() {
       @Session["_isSurveyPassed"] = true;
    }

This will produce

function hideSurveyReminder() {
       False = true;
    }

in browser =(

Never ever mix more languages.

<script type="text/javascript">
    var data = @Json.Encode(Model); // !!!! export data !!!!

    for(var prop in data){
      console.log( prop + " "+ data[prop]);
    }

In case of problem you can also try

@Html.Raw(Json.Encode(Model));

A non conventional method to separate javascript from the view, but still use razor in it is to make a Scripts.cshtml file and place your mixed javascript/razor there.

Index.cshtml

<div id="Result">
</div>

<button id="btnLoad">Click me</button>

@section scripts
{
    @Html.Partial("Scripts")
}

Scripts.cshtml

<script type="text/javascript">
    var url = "@Url.Action("Index", "Home")";

    $(document).ready(function() {
        $("#btnLoad").click(function() {
            $.ajax({
                type: "POST",
                url: url ,
                data: {someParameter: "some value"},
                contentType: "application/json; charset=utf-8",
                dataType: "json",

                success: function(msg) {
                    $("#Result").text(msg.d);
                }
            });
        });
    });
</script>
