选择复选框！==选择行表 [英] Select Checkbox !== Select Row Table

问题描述

select/unselect按钮在该复选框上起作用.

但是它不适用于行表.

//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);
});

我认为清单仅是用于显示，用于选定的行并对其进行标记.

I think the checklist is just for display, for row selected and to mark it.

单击选择/取消选择按钮时的方式，

How when the select / unselect button is clicked,

在行上选择 表格，不仅在复选框上?

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

您可以查看是否单击了行表.

You can see if you click the row table.

代码段演示:

$('#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);
});

推荐答案

一种方法是在提供

One way to do it is to call .toggleClass() on the rows providing the second argument that says whether to add or remove the class:

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

已添加到您的演示中:

$('#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);
});
