我在 ASP.NET 中使用 jquery 饼图。饼图工作正常，但我想绑定数据库中的值。如何在饼图中绑定数据库值。我在数据库中创建了一个表，我想从数据库中获取值到饼图中。

简单的解决方案是将数据库中的值放在隐藏字段中，然后使用 javascript 访问它们并获取它们的值以用作系列的一部分。这是 ASPX：

....
 <asp:HiddenField ID="FireFoxDataValueFromDB" runat="server" />
 <asp:HiddenField ID="IEDataValueFromDB" runat="server" />
....

这是CS：

Page_Load Event()
{
    if (!IsPostBack)
    {
        FireFoxDataValueFromDB = getFFDBValue();
        IEDataValueFromDB = getIEDBValue
    }
}
....

这是Javascript：

var FFVal = $("#FireFoxDataValueFromDB").val();
var IEVal = $("#IEDataValueFromDB").val();

and then use it as the series data:
 series: [
                        {
                            type: 'pie',
                            name: 'Browser share',
                            data: [
                                ['Firefox', FFVal],
                                ['IE', IEVal],
                                {
                                    name: 'Chrome',
                                    y: 12.8,
                                    sliced: true,
                                    selected: true
                                }, ['Safari', 8.5],
                                ['Opera', 6.2],
                                ['Others', 0.7]
                            ]
                        }...
