Question

我正在尝试在单击第一个数据表中的行时导航到R shiny中的另一个数据表选项卡。我在这里看到类似的例子。但是我无法使用它们，因为我将数据从数据库直接提取到数据表中。

Hyperlink from one DataTable to another in Shiny

你能指导我如何完成它吗？

        output$TbTable <- DT::renderDataTable(datatable(sqlOutput(),style = 'bootstrap', class = 'table-striped table-hover table-condensed',
                                                    extensions = c("FixedColumns","Scroller"),
                                                    filter = 'top',
                                                    options = list(
                                                      # dom = 't',
                                                      # deferRender = TRUE,
                                                      searching = TRUE,
                                                      autoWidth = TRUE,
                                                      # scrollCollapse = TRUE,
                                                      rownames = FALSE,
                                                      scroller = TRUE,
                                                      scrollX = TRUE,
                                                      scrollY = "500px",
                                                      #fixedHeader = TRUE,
                                                      class = 'cell-border stripe',
                                                      fixedColumns = list(
                                                        leftColumns = 3,
                                                        heightMatch = 'none', escape = FALSE,
            options = list(initComplete = JS(
              'function(table) {
    table.on("click.dt", "tr", function() {
    Shiny.onInputChange("rows", table.row( this ).index());
    tabs = $(".tabbable .nav.nav-tabs li a");
    $(tabs[1]).click();
    });
}'))
))))

你能帮我解决这个问题吗？

谢谢，

我没有深入参与DT，但这个JS回调函数有效：

function(settings, json) {
  var table = this.DataTable();
  table.on("click.dt", "tr", function() {
    Shiny.onInputChange("rows", table.row( this ).index());
    var tabs = $(".tabbable .nav.nav-tabs li a");
    $(tabs[1]).click();
  });
}
