Button Highcharts下载/上下文按钮中添加的选项会重复
我在Highcharts的下载/导出/上下文按钮中添加了一些选项。然而，这个过程有点复杂，因为它是一个API。一个文件正在接收调用，在生成图形的所有选项的地方调用另一个文件，然后返回到生成图形的第一个文件。此处，上下文按钮中引入了其他选项：Button Highcharts下载/上下文按钮中添加的选项会重复,button,highcharts,download,Button,Highcharts,Download,我在Highcharts的下载/导出/上下文按钮中添加了一些选项。然而，这个过程有点复杂，因为它是一个API。一个文件正在接收调用，在生成图形的所有选项的地方调用另一个文件，然后返回到生成图形的第一个文件。此处，上下文按钮中引入了其他选项： function drawGraph(selectedID, selectedCountries, selectedYears, per_capita, graphBorder, graphSource, graphDefinition, graph

谢谢你的提示。我终于找到了一种似乎很有效的方法。这是通过contextButton的菜单项数组进行循环。检查项目是否已存在，替换其功能。否则，请使用标准推送选项 希望这能帮助其他类似情况的人

“选择一个接一个的图形”？这意味着什么？@Strand：这意味着我调用显示图形的网站，然后选择另一个变量，然后图形显示该变量。第二次“加载”或“调用”显示图表，然后生成一个包含两个“元数据”条目的下拉列表。查看屏幕截图。这意味着每次创建新图表时，都要添加
