本文实例讲述了jquery实现自定义树形表格的方法。分享给大家供大家参考，具体如下：

话不多说，直接上代码（本代码仅提供思路）：

function createTables(data, t, p) { $("#datatable" + t + ' tbody').empty(); var count = data.length; var html = ''; if (count > 0) { for (var i = 0; i < count; i++) { var btn = ''; if(data[i]._child && data[i]._child.length > 0){ btn = '<i class="layui-icon mt-icon" style="cursor: pointer" data-tid="'+ data[i].category_id +'-'+ data[i].id +'-'+ t +'" data-pid="'+ data[i].category_id +'-'+ data[i].pid +'-'+ t +'">&#xe623;</i> '; }else{ btn = '<i class="mt-icon" style="cursor: pointer" data-tid="'+ data[i].category_id +'-'+ data[i].id +'" data-pid="'+data[i].category_id +'-'+ data[i].pid+'"></i> '; } html += '<tr style="">' + '<td style="text-align: left">'+btn + data[i].name + '（' + data[i].title + '）' + '</td>' + '<td>' + (data[i].source_name ? data[i].source_name : '') + '</td>' + '<td>' + data[i].show_time + '</td>' + '<td>' + dataFormat(data[i].current_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].prev_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].last_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].budget, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].budget_rate, '%') + '</td>' + '<td>' + dataFormat(data[i].record_rate) + '</td>' + '<td>' + dataFormat(data[i].mom, '%') + '</td>' + '<td>' + dataFormat(data[i].yoy, '%') + '</td>' + '<td><i class="layui-icon" style="cursor: pointer" onclick="showHiddenArea(this,' + data[i].category_id + ',' + data[i].data_structure_id + ',' + data[i].time_unit + ',' + t + ');">&#xe62c;</i></td> ' + '</tr>'; if(data[i]._child && data[i]._child.length > 0){ html = createNewTable(data[i]._child,html,1,t); } } } else { html = '<tr><td colspan="12" style="text-align: center"> 暂无数据 </td></tr>'; } $("#datatable" + t + ' tbody').html(html); // 插入的表格 initTreeAction(t); // 结构初始化}function createNewTable(data,html,y,t){ var counts = data.length; var num = ++y; for (var i = 0; i < counts; i++) { var btn = ''; var css = ''; css = 'text-indent:'+ (num * 20) +'px;'; if(data[i]._child && data[i]._child.length > 0){ css = 'text-indent:'+ (num==2?20:(num-1) * 20) +'px;'; btn = '<i class="layui-icon mt-icon" style="cursor: pointer" data-tid="'+ data[i].category_id +'-'+ data[i].id +'-'+ t +'" data-pid="'+data[i].category_id +'-'+ data[i].pid+'-'+ t +'" data-type="dir">&#xe623;</i> '; }else{ btn = '<i class="mt-icon" style="cursor: pointer" data-tid="'+ data[i].category_id +'-'+ data[i].id +'-'+ t +'" data-pid="'+data[i].category_id +'-'+ data[i].pid +'-'+ t +'" data-type="file"></i> '; } html += '<tr style="display: none">' + '<td style="text-align: left; '+ css +'">'+ btn + data[i].name + '（' + data[i].title + '）' + '</td>' + '<td>' + (data[i].source_name ? data[i].source_name : '') + '</td>' + '<td>' + data[i].show_time + '</td>' + '<td>' + dataFormat(data[i].current_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].prev_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].last_record, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].budget, data[i].unit) + '</td>' + '<td>' + dataFormat(data[i].budget_rate, '%') + '</td>' + '<td>' + dataFormat(data[i].record_rate) + '</td>' + '<td>' + dataFormat(data[i].mom, '%') + '</td>' + '<td>' + dataFormat(data[i].yoy, '%') + '</td>' + '<td><i class="layui-icon" style="cursor: pointer" onclick="showHiddenArea(this,' + data[i].category_id + ',' + data[i].data_structure_id + ',' + data[i].time_unit + ',' + t + ');">&#xe62c;</i></td> ' + '</tr>'; if(data[i]._child && data[i]._child.length > 0){ html = createNewTable(data[i]._child,html,num,t); } } return html;}function showLowData(obj){ var mId = $(obj).attr('data-tid'); var isOpen = $(obj).hasClass('open'); if (isOpen) { $(obj).removeClass('open'); if($(obj).hasClass('layui-icon')){ $(obj).html('&#xe623;'); } } else { $(obj).addClass('open'); if($(obj).hasClass('layui-icon')){ $(obj).html('&#xe625;'); } } $(obj).parents('tbody').find('tr').each(function () { var mt = $(this).find('.mt-icon'); var pid = mt.attr('data-pid'); var Open = mt.hasClass('open'); var type = mt.attr('data-type'); if (mId == pid) { if (isOpen) { $(this).hide(); if (type == 'dir' && Open == isOpen) { mt.trigger('click'); } } else { $(this).show(); } } });}
