asp 用fusionchart做图表，怎么读取access数据库中的数据用到fusionchart中？

Answer 1

第一步：用asp连接access查询数据表中的数据。

第二步：根据fusionchart 调用的js文件中的"data": [{..}]部分，按照固定格式输出；

    此步骤是关键，就是按照fusionchart 要求输出即可，有两种方法，1是在当前HTML页面中直接通过asp的 response.write(rs("value"));输出数据库内容。2是输出内容以后保存js文档，供html调用。

第三步：正常调用fusionchart 输出图表；

举例子：

FusionCharts.ready(function () {
    var revenueChart = new FusionCharts({
        type: 'doughnut2d',
        renderAt: 'chart-container',
        width: '450',
        height: '450',
        dataFormat: 'json',
        dataSource: {
            "chart": {
                "caption": "Split of Revenue by Product Categories",
                "subCaption": "Last year",
                "numberPrefix": "$",
                "paletteColors": "#0075c2,#1aaf5d,#f2c500,#f45b00,#8e0000",
                "bgColor": "#ffffff",
                "showBorder": "0",
                "use3DLighting": "0",
                "showShadow": "0",
                "enableSmartLabels": "0",
                "startingAngle": "310",
                "showLabels": "0",
                "showPercentValues": "1",
                "showLegend": "1",
                "legendShadow": "0",
                "legendBorderAlpha": "0",
                "defaultCenterLabel": "Total revenue: $64.08K",
                "centerLabel": "Revenue from $label: $value",
                "centerLabelBold": "1",
                "showTooltip": "0",
                "decimals": "0",
                "captionFontSize": "14",
                "subcaptionFontSize": "14",
                "subcaptionFontBold": "0"
            },
            "data": [
                //原js文件中的格式要求部分
                //{
                //    "label": "Food",
                //    "value": "28504"
                //}, 
                //{
                //    "label": "Apparels",
                //    "value": "14633"
                //}, 
                //{
                //    "label": "Electronics",
                //    "value": "10507"
                //}, 
                //{
                //    "label": "Household",
                //    "value": "4910"
                //}
                //注意这里开始用asp输出
                
                <%
                for i=1 to rs.recordcount
if rs.eof then exit for
                
                if i<rs.recordcount then
                    response.write("{"label":" & rs("name") & ",")
                    response.write(""value":") & rs("value") & "},")
                else
                    response.write("{"label":" & rs("name") & ",")
                    response.write(""value":") & rs("value") & "}")
                end if
                
                rs.movenext:next
                %>
            ]
        }
    }).render();
});
