Well you can use something like this:
那么你可以使用这样的东西：
foreach (var item in collection) {
<script type="text/javascript">
JK();
</script>
}
If you need to use foreach inside the javascript code, you should just use . Like this:

You can't call JS function on server side only in the views. And it wiil look like
您不能仅在视图中调用服务器端的 JS 函数。它看起来像
@foreach(var item in collection)
{
...
<script type="text/javascript">
JK()
</script>
...
}
Output html will contain several calls of this js function.
输出 html 将包含此 js 函数的多个调用。

I would implement it little bit differently
我会以不同的方式实现它
@foreach(var item in collection)
{
<!-- some html element that will be generated on each loop cycle
<input type="hidden" class="item"/>
}
then with/without help of 3rd party JavaScript libraries
然后有/没有 3rd 方 JavaScript 库的帮助
$(document).ready(function () {
$('.item').each(function () {
JK();
}
});

To call a javascript function
调用 javascript 函数
//C# Code
@Html.Raw("CallFunction('" + @param + "');");
//C# code..
Now for Javascript function
现在为 Javascript 功能
<script type="text/javascript">
CallFunction(param)
{
alert(param);
}
</script>
