jquery实现自定义树形表格的方法【自定义树形结构table】

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 +'"></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 + ');"></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"></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 + ');"></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('');      }    } else {      $(obj).addClass('open');      if($(obj).hasClass('layui-icon')){        $(obj).html('');      }    }    $(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();        }      }    });}
