MVC: Iterating a Viewbag array in javascript
提问by Esa
The goal is to get the data from the ViewBag.Arrayto 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:
目标是将数据从ViewBag.Array到 Javascript 数组。数据是在控制器中计算的，所以我无法直接从数据库中获取它。我需要使用 jqplot 绘制图表的数据。代码：
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“'i' 在当前上下文中不存在”，@ViewBag.Array[i]但在jScriptArray[i]. 任何帮助表示赞赏。

You may try the following:
您可以尝试以下操作：
var array = @Html.Raw(Json.Encode(@ViewBag.Array));
for(var i = 0; i < array.length; i++) {
jScriptArray[i] = array[i];
}

<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:
你最终会在 html 文件中得到这样的东西：
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.
您可以从您的 javascript 请求数据，然后对其进行处理。
Hope this helps
