我有一个带有select all选项的数据表。我的数据表包含文件和链接。我只需要选择包含文件的行。选定的计数在那里显示。我的代码在
下var mydata = $('#document-table').DataTable({
"dom": 'Bfrtip',
"info": false,
"pageLength": 20,
"searching": false,
"lengthChange": false,
"select": {
'style': 'multi',
'selector': 'tr:not(.no-select)'
},
"rowCallback": function( row, data, index ){
if(data[2] == ''){
$('td:eq(0)', row).removeClass('select-checkbox');
$(row).addClass('no-select');
}
else {
$(row).removeClass('no-select');
}
},
"columnDefs": [
{
'targets': 0,
'checkboxes': {
'selectRow': true
},
'render': function(){
return '';
}
},
],
"order": [[ 1, 'asc' ]],
});
mydata.on("click", "th.select-checkbox", function() {
if ($("th.select-checkbox").hasClass("selected")) {
mydata.rows().deselect();
$("th.select-checkbox").removeClass("selected");
} else {
mydata.rows().select();
$("th.select-checkbox").addClass("selected");
}
}).on("select deselect", function() {
var count = mydata.rows({
selected: true
}).count();
if (count !== mydata.rows().count()) {
$("th.select-checkbox").removeClass("selected");
} else {
$("th.select-checkbox").addClass("selected");
}
mydata.rows('tr.no-select').deselect();
});
当我单击全选按钮时，需要取消选择类为'.no-select'的每一行。我的代码适用于首页。但是在其他页面中，所有行均被选中。我该如何解决这个问题？
答案 0 :(得分：0)
您可以在点击事件中使用相同的查询来过滤选择器
tr:not(.no-select)
喜欢
$(this).closest('table').find('tbody tr:not(.no-select) ').toggleClass("selected",this.checked);
不太完美，请根据下面的要求查看示例。
第二列为空的示例在第1和4页上
var mydata = $(document).ready(function() {
$('#example').DataTable( {
"rowCallback": function( row, data, index ){
if(data[2] == ''){
$('td:eq(0)', row).removeClass('select-checkbox');
$(row).addClass('no-select');
}
else {
$(row).removeClass('no-select');
}
},
columnDefs: [ {
orderable: false,
className: 'select-checkbox',
targets: 0
} ],
select: {
style: 'multi',
selector: 'tr:not(.no-select)'
},
order: [[ 1, 'asc' ]]
} );
} )
mydata.on("click", "th.select-checkbox input", function() {
$(this).closest('table').find('th.select-checkbox input').prop('checked', this.checked);
$(this).closest('table').find('tbody tr:not(.no-select) ').toggleClass("selected",this.checked);
