我是n00bie。很抱歉，如果这对你们中的某些人来说不是一个合适的问题。也许有人会帮助我。我想在 C#/.net 中开发一个带有一些控件和 ajax 可更新图表（基于 MVC）的简单工具。我找到了一个简单而干净的教程。但它是在 2010 年写的。我想知道它是否有点现代？或者已经改变了什么并且这种风格已经过时了？如果在按下某些按钮后使用 jquery 在图表上执行更新是一个好主意，我特别感兴趣？
我还包括本教程的一个片段，所以也许你能让我变得更好：
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Annual Sales Data (With Fancy JavaScript!)
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="HeadContent" runat="server">
<script type="text/javascript">
$(document).ready(function () {
// Populate the Categories and Years DDLs with the values from the server
$.getJSON('/Api/Years', // URL that returns data of interest
function (result) { // The function that executes once the data has been returned
var years = $("#years");
$.each(result, function (index, year) {
years.append($("<option />").val(year).text(year));
});
$.getJSON('<%=Page.ResolveClientUrl("~/Api/Categories")%>', // URL that returns data of interest
function (result) { // The function that executes once the data has been returned
var categories = $("#categories");
$.each(result, function (index, categoryName) {
categories.append($("<option />").val(categoryName).text(categoryName));
});
// Load the image
UpdateImage();
});
});
// Add client-side event handlers to these DDLs
$("#years").change(UpdateImage);
$("#categories").change(UpdateImage);
});
function UpdateImage() {
var selectedYear = $("#years").val();
var selectedCategory = $("#categories").val();
$("#chart").fadeOut(function () {
$(this).attr('src', '/Charts/SalesByYear?CategoryName=' + escape(selectedCategory) + '&OrderYear=' + escape(selectedYear) + '&showTitle=false')
.attr('alt', 'Sales for ' + selectedCategory + ' in ' + selectedYear)
.attr('title', 'Sales for ' + selectedCategory + ' in ' + selectedYear);
$(this).fadeIn();
});
}
</script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Annaul Sales Data (With Fancy JavaScript)</h2>
<p>
This demo shows how to gussy up the sales data charting example using a tad of JavaScript and jQuery.
</p>
<div style="text-align: center">
<h2 style="text-align: center">Sales For <select id="categories"></select> In <select id="years"></select></h2>
<img id="chart" style="display:none" />
</div>
</asp:Content>
任何人都可以向我推荐任何教程，我可以在其中了解如何使用 flotcharts 实现基于 mvc 的 Web 应用程序？
谢谢！
