Razor MVC Populating Javascript array with Model Array


I'm trying to load a JavaScript array with an array from my model. Its seems to me that this should be possible.

Neither of the below ways work.

Cannot create a JavaScript loop and increment through Model Array with JavaScript variable

for(var j=0; j<255; j++)
{
    jsArray = (@(Model.data[j])));
}

Cannot create a Razor loop, JavaScript is out of scope

@foreach(var d in Model.data)
{
    jsArray = d;
}

I can get it to work with

var jsdata = @Html.Raw(Json.Encode(Model.data)); 

But I don't know why I should have to use JSON.

Also while at the moment I'm restricting this to 255 bytes. In the future it could run into many MBs.


Solution

  • This is possible, you just need to loop through the razor collection

    <script type="text/javascript">
    
        var myArray = [];
    
        @foreach (var d in Model.data)
        {
            @:myArray.push("@d");
        }
    
        alert(myArray);
    
    </script>
