javascript - 选择复选框 !== 选择行表

Question

选择/取消选择按钮作用于复选框。

但它不适用于行表。

//Select row table
$('#example').on('click', 'tr', function() {
  var $row = $(this),
    isSelected = $row.hasClass('selected')
  $row.toggleClass('selected')
    .find(':checkbox').prop('checked', !isSelected);
});

// Problem : Checkbox !== select row
$("#selectAll, #unselectAll").on("click", function() {
  var selectAll = this.id === 'selectAll';
  $("#example tr :checkbox").prop('checked', selectAll);
});

我认为 list 只是为了显示，用于选择行并标记它。

How when the select / unselect button is clicked,

it select on row table too, Not just on the checkbox?

点击行表就可以看到

代码片段演示:

$('#example').dataTable();

//Select row table
$('#example').on('click', 'tr', function() {
  var $row = $(this),
    isSelected = $row.hasClass('selected')
  $row.toggleClass('selected')
    .find(':checkbox').prop('checked', !isSelected);
});

// Problem : Checkbox !== select row
$("#selectAll, #unselectAll").on("click", function() {
  var selectAll = this.id === 'selectAll';
  $("#example tr :checkbox").prop('checked', selectAll);
});

一种方法是在提供 second argument 的行上调用 .toggleClass()说是添加还是删除类:

  $("#example tr").toggleClass("selected", selectAll)
    .find(":checkbox").prop('checked', selectAll);

添加到您的演示:

$('#example').dataTable();

//Select row table
$('#example').on('click', 'tr', function() {
  var $row = $(this),
    isSelected = $row.hasClass('selected')
  $row.toggleClass('selected')
    .find(':checkbox').prop('checked', !isSelected);
});

// Problem : Checkbox !== select row
$("#selectAll, #unselectAll").on("click", function() {
  var selectAll = this.id === 'selectAll';
  $("#example tr").toggleClass("selected", selectAll)
    .find(":checkbox").prop('checked', selectAll);
});
