我创建了MVC 5(使用Razor语法),我希望使用morris-area-chart显示数据。我想使用模型中的数据(即数据库),我将其传递到我的视图中,以便我可以在morris-area-chart中使用它。
有人可以告诉我如何构建和替换以下morris-area-chart配置元素数据,以便使用从模型中获取的数据来设置这些元素吗?
data: [{ period: '2010-01-01', iphone: 2666, ipad: null, itouch: 2647 },
{ period: '2010-01-02', iphone: 2778, ipad: 2294, itouch: 2441 },
{ period: '2010-01-03', iphone: 4912, ipad: 1969, itouch: 2501 },
{ period: '2010-01-04', iphone: 3767, ipad: 3597, itouch: 5689 }],
labels: ['iPhone', 'iPad', 'iPod Touch'],
如果使用模型和Razor语法无法实现上述请求,请说明从模型(即数据库)显示数据的正确方法。
查看:
@model Project.Models.ShowGraphViewModel
....
<div id="morris-area-chart"></div>
@section Styles {
@Styles.Render("~/plugins/morrisStyles")
}
@section Scripts {
@Scripts.Render("~/plugins/morris")
<script>
Morris.Area({
element: 'morris-area-chart',
data: [{ period: '2010-01-01', iphone: 2666, ipad: null, itouch: 2647 },
{ period: '2010-01-02', iphone: 2778, ipad: 2294, itouch: 2441 },
{ period: '2010-01-03', iphone: 4912, ipad: 1969, itouch: 2501 },
{ period: '2010-01-04', iphone: 3767, ipad: 3597, itouch: 5689 }],
xkey: 'period',
ykeys: ['iphone', 'ipad', 'itouch'],
labels: ['iPhone', 'iPad', 'iPod Touch'],
xLabels: "day",
pointSize: 2,
hideHover: 'auto',
resize: true,
lineColors: ['#87d6c6', '#54cdb4', '#1ab394'],
lineWidth: 2,
pointSize: 1,
});
</script>
}
控制器:
// GET: ShowGraph
public ActionResult ShowGraph()
{
// Create model to pass to View
ShowGraphViewModel graphModel = new ShowGraphViewModel();
// How to construct following for morris-area-chart?
// data: ?.....
// labels = ?....
return View(graphModel);
}
型号:
public class ShowGraphViewModel
{
//What do I put in here?
}
答案 0 :(得分:0)
您查看模型需要2个属性IEnumerable<T> Data
和T
,其中period
是包含iphone
,public class ChartDataVM
{
public string period { get; set; }
public int iphone { get; set; }
public int? ipad { get; set; }
public int itouch{ get; set; }
}
public class ShowGraphViewModel
{
public IEnumerable<ChartDataVM> Data { get; set; }
public IEnumerable>string> Labels { get; set; }
}
等属性的模型。例如
var model = new ShowGraphViewModel()
{
Data = new List<ChartDataVM>
{
new ChartDataVM(){ period "2010-01-01", iphone = 2666, itouch = 2647 },
new ChartDataVM(){ period "2010-01-02", .... },
....
},
Labels = new List<string>(){ "iPhone", "iPad", .... }
};
return View(model);
并且在GET方法中,您可以使用
生成它<script>
var model = @Html.Raw(Json.Encode(Model))
Morris.Area({
element: 'morris-area-chart',
data: model.Data,
xkey: 'period',
....
labels: model.Labels,
....
然后在视图中,您可以将模型分配给javascript对象并将其属性分配给插件
List<string> LineColors
视图模型还可以包含插件所需的其他属性,例如{{1}}
