当我加载页面时，一些复选框应该被禁用并且用户不应该能够选择它们。例如，在加载页面时，应该禁用带有奇数“id”的行的复选框。但不应禁用整行，仅禁用复选框。我一直试图弄清楚很长时间，但我找不到任何答案。提前致谢。这是我的代码。

一旦网格被渲染，jQuery 就可以查找复选框。

您可以使用PQ Grid类来选择行。

  • .pq-grid-row是每一行的类。
  • .pq-grid-oddRow是奇数行的类。
  • .pq-grid-title-row是标题行的类。

因此，要获得偶数行，您可以使用所有行选择器和.not()选择器。

要定位复选框，请使用属性选择器。

// Disable the columns checkboxes (check all)
$(".pq-grid-title-row [type='checkbox']").prop("disabled",true);

// Disable checkboxes on even rows.
$(".pq-grid-row:not(.pq-grid-oddRow) [type='checkbox']").prop("disabled",true);

// Disable checkboxes on odd rows.
$(".pq-grid-oddRow [type='checkbox']").prop("disabled",true);

这是一个片段，其中奇数行上的复选框和“全选”列被禁用。
