Question

我的.rdl报告中具有此功能，

 Public Function GetBarcodeAddress(datastring As String, serverName As String) as String
    GetBarcodeAddress=String.format("http://serverName/barcode/barcode.ashx?data={0}", datastring )
    End Function

最初它是“ localhost”，但是我想根据要根据服务器名在服务器名中传递的值来使其动态化

 Public Function GetBarcodeAddress(datastring As String) as String
    GetBarcodeAddress=String.format("http://localhost/barcode/barcode.ashx?data={0}", datastring )
    End Function

但是当我更新报告时，没有生成条形码。

但是我手动运行URI可以，但是在实际报告中没有生成条形码。

我是否只需要在域名部分输入变量名？

要使其正常工作，您需要：

<script type="text/javascript">
        google.charts.load('current', {'packages':['corechart']});
        google.charts.setOnLoadCallback(drawVisualization);

        function drawVisualization() {
            google.charts.load("current", {packages:['corechart']});
            google.charts.setOnLoadCallback(drawChart);
            function drawChart() {
                var data = google.visualization.arrayToDataTable([
                    [ 'Element', "Density", { role: "style" } ],
                    ${data1}
                ]);

                var view = new google.visualization.DataView(data);
                view.setColumns([0, 1,
                    { calc: "stringify",
                        sourceColumn: 1,
                        type: "string",
                        role: "annotation" },
                    2]);

                var options = {
                    title: "Density of Precious Metals, in g/cm^3",
                    width: 600,
                    height: 400,
                    bar: {groupWidth: "95%"},
                    legend: { position: "none" },
                };
                var chart = new google.visualization.ColumnChart(document.getElementById("ord_variation"));
                chart.draw(view, options);
        }}
    </script>
