使用html+css+layui实现动态表格组件

1、概述

需求，表格第一列指标可配置通过后端api传进来，表格显示数据以及鼠标触摸后气泡弹出层提示信息都是从后端传过来，实现动态表格的组件！！实现效果如下：

接口标准数据格式如下：

{
    "data": {
        "date": [
            "8.20",
            "8.21",

            "8.28",
            "8.29",

                    "hide": ""
                },
                {

                {

                    "show": "<img style='width:20px;height:20px;' src='/pharmacistws/image/BLOOD.jpg'/>",

                    "id": "58",
                    "show": "",
                    "hide": ""
                },
                {
                    "id": "59",

                    "show": "",
                    "hide": ""
                }
            ]
        }
    },
    "r_code": 1
}

2、实现代码

js代码

// 渲染表格数据
function renderTable(eleIdName, eleIdName1, eleIdName2,data) {
    var tableHeader = document.querySelector(eleIdName);
    var dayNum = document.querySelector(eleIdName1);
    var tableHide = document.getElementById(eleIdName2);
    // 渲染列头
    for (var i = 0; i < data.date.length; i++) {
        var headerCell = document.createElement('div');
        headerCell.classList.add('header-cell');
        headerCell.textContent = data.date[i];
        tableHeader.appendChild(headerCell);

        var headerCell1 = document.createElement('div');
        headerCell1.classList.add('header-cell');
        headerCell1.textContent = data.hosDays[i];
        dayNum.appendChild(headerCell1);
    }
    // 渲染数据
    var dataHtml = '';
    for (var key in data.tableData) {
        dataHtml += '<div class="table-row">';
        dataHtml += '<div class="cell">';
        dataHtml += key;
        dataHtml += '</div>';
        for (var i = 0; i < data.tableData[key].length; i++) {
            dataHtml += '<div class="cell" id="'+data.tableData[key][i].id+'" onmouseover="tableShow('+data.tableData[key][i].id+')" onmouseout="tableCloseTip()">';
            dataHtml += data.tableData[key][i].show;
            dataHtml += '</div>';
            var newElement = document.createElement('div');
            newElement.id= "hide_"+data.tableData[key][i].id;
            newElement.innerHTML = data.tableData[key][i].hide;
            tableHide.appendChild(newElement);
        }
        dataHtml += '</div>';
    }
    dayNum.insertAdjacentHTML('afterend', dataHtml);
}

function tableShow(d) {
    layui.use(['layer'],function(){
        var layer = layui.layer;
        var hide = document.getElementById("hide_"+d);
        if(hide.innerHTML!=='') {
            tips = layer.tips(hide.innerHTML, "#"+d, {
                tips: [1, '#F8F8F8'],
                area: ['300px','auto'],
                time: 60000
            });
            // $("#layui-layer" + tips).css("position","fixed");
        }
    });
}

function tableCloseTip () {
    layui.use(['layer'],function(){
        var layer = layui.layer;
        layer.close(tips);
    });
}

如何使用

                var tableHtml = '            <div style="overflow-x: auto;">\n' +
                    '                <div class="table">\n' +
                    '                    <div class="table-header" id="tableHeader">\n' +
                    '                        <div class="header-cell">日期</div>\n' +
                    '                        <!-- 更多列头 -->\n' +
                    '                    </div>\n' +
                    '                    <div class="table-header" id="inHosDay">\n' +
                    '                        <div class="header-cell">住院日</div>\n' +
                    '                    </div>\n' +
                    '                    <!-- 更多单元格 -->\n' +
                    '                </div>\n' +
                    '                <div id="tableHide" style="display:none">\n' +
                    '\n' +
                    '                </div>\n' +
                    '            </div>'
                $("#table1").append(tableHtml);
                renderTable("#tableHeader","#inHosDay",'tableHide',ret.data);

注意需要引用layui组件
