基于if条件的jQuery DataTable列

【中文标题】基于if条件的jQuery DataTable列【英文标题】:jQuery DataTable columns based on if condition 【发布时间】:2021-09-07 13:34:40 【问题描述】:我们可以为 jQuery dataTables 列做if
条件吗?根据变量值,我想决定显示/隐藏哪一列。
我尝试通过创建一个对象并将其传递给DataTable()
函数来实现这一点,方法是使用扩展运算符提取列,如下所示:
if (offer = "offer1")
const offerCols =
"columns": [
"data": "ioName", "class": "align-middle",
"data": "salesPrice","class": "align-middle",
"data": "offerPrice","class": "align-middle",
"data": "offerQty","class": "align-middle",
],
else
const offerCols =
"columns": [
"data": "ioName", "class": "align-middle",
"data": "salesPrice","class": "align-middle",
"data": "offerPrice","class": "align-middle",
"data": "offerQty","class": "align-middle",
"data": "validPeriod","class": "align-middle",
],
var $table = $("#table").DataTable(
"ajax": '/view_offers.php',
...offerCols,
"classes":
sLength: "text-left w-auto",
)
但是,这对我不起作用。如何解决以下问题?
【问题讨论】:
【参考方案1】:如果您正在寻找用于查看数据的条件列,那么答案是 YES。但我不明白为什么传播运算符。
下面是根据条件自定义列渲染的代码。

【讨论】:
感谢您的回答。你能说出这在多种条件下是如何工作的吗(if、elseif、elseif、else)等。 @user3733831 如您所见,有一个自定义渲染函数,您可以将 if else 条件放在那里,并将必要的列放入列数组中。以上是关于基于if条件的jQuery DataTable列的主要内容,如果未能解决你的问题,请参考以下文章
如何在 Jquery Datatables 中根据条件隐藏列?
