Passing Viewbag value to javascript function

Question

I am new to MVC and trying from last 7 hours to pass value from viewBag to javascript function in MVC 5. I have a string variable

ViewBag.c1 = "0.30"

and i passed it to view and stored it as a hidden element

@Html.Hidden("Superman", (string)ViewBag.c1)

and then i want to access the value of this hidden element in following js function

function getValue1() {
return parseFloat(document.getElementById("Superman"));
}

The hidden input is not necessary. You can just use function getValue1() { return @Html.Raw(Json.Encode(ViewBag.c1)) } and the controller code should be ViewBag.c1 = 0.30F; is you want a number — user3559349

You could simply store view-bag value in JavaScript variable like below.

<script> var yourValue = '@ViewBag.c1' </script>
