jQuery数据表过滤具有特定类的行 [英] jQuery datatables filter row with specific class
问题描述
我正在一个jQuery Datatable项目中,我需要根据特定的行类过滤数据.我要根据条件在创建行时将类添加到我的行中.我试图找出一种方式让用户单击按钮,该按钮将应用仅显示包含特定类的行的过滤器.
I am working on a jQuery Datatable project where I need to filter the data based on specific row classes. I'm adding classes to my rows upon row creation based on a condition. I'm trying to figure out a way for my user to click a button which would apply a filter that only displays rows that contain a specific class.
我尝试了几种不同的解决方案,但似乎无法使其工作.有人知道如何正确执行此操作吗?
I've tried a few different solutions but I can't seem to make it work. Does anyone know how to do this correctly?
这是 JSFiddle
$('#table').DataTable({
data: data,
columns: [
{
"data": "item1",
"render": function ( data, type, row ) {
if(type === 'display'){
return "<span class='format1'>"+data+"</span>";
}else if(type === 'sort'){
return data;
}else if(type === 'filter'){
return data;
}else{
return data;
}
}
},
{
"data": "item2",
"render": function ( data, type, row ) {
if(type === 'display'){
return "<span class='format2'>"+data+"</span>";
}else if(type === 'sort'){
return data;
}else if(type === 'filter'){
return data;
}else{
return data;
}
}
}
],
createdRow: function ( row, data, index ) {
if (data.item2 == 'this is item 2 - meets condition1') {
$(row).addClass('condition1');
}
if (data.item2 == 'this is item 2 - meets condition2') {
$(row).addClass('condition2');
}
}
});
$('#btn-filter').on('click',function(){
//// only show table data that contains the class condition1
});
$('#btn-undo').on('click',function(){
//// remove the filter that was applied with btn-filter
});
推荐答案

Working fiddle.
您可以使用:
$.fn.dataTable.ext.search.push(
function(settings, data, dataIndex) {
return $(table.row(dataIndex).node()).hasClass('condition1');
}
);
要过滤表格,然后重置即可,只需使用:
To filter the table, then to reset it just use :
$.fn.dataTable.ext.search.pop();
请注意,您应该在两个actios之后重新绘制.
Note that you should refdraw after the both actios.
希望这会有所帮助.
let data = [{
"item1": "this is item 1 - data set 1",
"item2": "this is item 2 - meets condition1"
}, {
"item1": "this is item 1 - data set 2",
