Use JavaScript Variable in Asp.net MVC Razor syntax

How to use JavaScript variables inside ASP.NET MVC Razor instructions?

Example:

function updChart(_IndId) {

    @foreach (var d in Model.Where(p => p.IndId.Equals(_IndId)))

...
}

I can't use _IndId variable. Any idea how to use it?

You can not use Javascript variables in C#, because javascript code is available only after C# / Razor is rendered.

What you can do, is to save the Model in a Javascript array, and then do the foreach loop in Javascript:

var model = [];
@foreach (var item in Model)
{
    @:model.push({
        @:ID: '@item.ID',
        @:Property1: '@item.Property1',
        @:Property2: '@item.Property2',
        @:Property3: '@item.Property3',
    @:});
}

console.log(model);
// here you can filter and do the foreach in Javascript, because your model is available as a Javascript array

You cannot do this. The Razor view is compiled and executed on server and its result is HTML page which is then returned to a client(browser). JavaScript runs in browser and allows you to work with the DOM of HTML page which is already returned from the server.
