如何使用Shiny R语法实现DataTables选项？

如何解决如何使用Shiny R语法实现DataTables选项？

我正在尝试使用在DataTables中找到的一些扩展选项为Shiny中的DataTable添加一个选项。

我要实现Opetion SearchBuilder.columns，以便搜索框只能在“ id”列中进行搜索 https://datatables.net/reference/option/searchBuilder.columns

如何在R Shiny中实现此选项？语法是什么？

下面的代码不起作用。

.item-inner {
    height: 100vh;
    background-size: 100% auto;
    background-repeat: no-repeat;
    background-position: center center;
    transition: all 6.2s linear;
    overflow: hidden;
}

.carousel-item.active .item-inner {
    transition: all 6.2s linear;
    background-size: 110% auto;
}

这是完整的代码：

<link href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js"></script>

<div id="zoomer" class="carousel slide carousel-fade" data-ride="carousel">

  <div class="carousel-inner">

    <div class="carousel-item active" id="activeOnLoad"> <!-- get the ID -->
      <div class="item-inner" style="background-image: url('https://i.picsum.photos/id/874/1920/1680.jpg?hmac=KDczwg-ejraLUmoflMNUBCkt1LyLxNreJptc7RQajFY')"></div>
    </div>

    <div class="carousel-item">
      <div class="item-inner" style="background-image: url('https://i.picsum.photos/id/878/1920/1680.jpg?hmac=_FQShv6E5HdjI6OKgjozFJQz8SXlT1OwmqijW5jHGQo')"></div>
    </div>

    <div class="carousel-item">
      <div class="item-inner" style="background-image: url('https://i.picsum.photos/id/870/1920/1680.jpg?hmac=IAkVJX2zYS6BuaMLixYh5xoyOpeDH5WkcGTacBUppxM')"></div>
    </div>

  </div>
  <a class="carousel-control-prev" href="#zoomer" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
  </a>
  <a class="carousel-control-next" href="#zoomer" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
  </a>
</div>

解决方法

真棒扩展！

在“ DT”包中不可用。这是使用方法。

首先，下载the JavaScript file and the CSS file。

然后，这是R代码：

library(DT)
library(htmltools)

dat <- data.frame(
  x = c(0,1,2,3,4),id = c("sub0","sub0","sub1","sub2")
)

dtable <- datatable(
  dat,options = list(
    dom = "Qlfrtip",searchBuilder = list(
      columns = list(2) # 2 is the index of the 'id' column
    )
  )
)

path_to_searchBuilder <- # path to the folder containing the two searchBuilder files
  normalizePath("~/Work/R/DT/searchBuilder/")

dep <- htmlDependency(
  name = "searchBuilder",version = "1.0.0",src = path_to_searchBuilder,script = "dataTables.searchBuilder.min.js",stylesheet = "searchBuilder.dataTables.min.css",all_files = FALSE
)

dtable$dependencies <- c(dtable$dependencies,list(dep))

dtable
