MVC：在javascript中迭代一个Viewbag数组

The goal is to get the data from the ViewBag.Array to a Javascript array. The data is calculated in the controller so I cannot fetch it straight from the database. I need the data to draw a chart with jqplot. Code:

目标是将ViewBag.Array中的数据转换为Javascript数组。数据在控制器中计算，因此我无法直接从数据库中获取数据。我需要数据用jqplot绘制图表。码：

for(i = 0; i < @ViewBag.Array.Length; i++)
{
    jScriptArray[i] = @ViewBag.Array[i];
}

The problem is "'i' does not exist in the current context" in the @ViewBag.Array[i] but has no problems in the jScriptArray[i]. Any help is appreciated.

问题是在@ ViewBag.Array [i]中“'我'在当前上下文中不存在”，但在jScriptArray [i]中没有问题。任何帮助表示赞赏。

You may try the following:

您可以尝试以下方法：

var array = @Html.Raw(Json.Encode(@ViewBag.Array));
for(var i = 0; i < array.length; i++) {
    jScriptArray[i] = array[i];
}

#2

<script>
var jScriptArray=[];
@{
    for(i = 0; i < ViewBag.Array.Length; i++){
      <text>jScriptArray[@i] = "@ViewBag.Array[@i]";</text>
      i++;
    }
  }
</script>

You will end up with something like this in html file:

你将在html文件中得到类似的东西：

jScriptArray[0] = "ArrayValue0";
jScriptArray[1] = "ArrayValue1";
jScriptArray[2] = "ArrayValue2";

The best way to achieve your goal is to create a JSON controller that returns the data into a JSON array.

实现目标的最佳方法是创建一个JSON控制器，将数据返回到JSON数组中。

From your javascript you can request the data and then process it.

从您的JavaScript您可以请求数据，然后处理它。
