<div class="table-div" style="display: block;width: 300px; height: 241px; margin: auto;"><table border="1" cellspacing="0" cellpadding="3" style=" width: 300px; height: 230px;"><tr><td colspan="2" height="80px"><div style="text-align: center"><img id="barcode"/></div></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">开发员：${logistics_id}</span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">SQE工程师：${logistics_id}</span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px"> 取样类型：${logistics_id} </span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px"> 收货地址：${work_address} </span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">建资料流水号：${logistics_id}</span></td></tr></table>

<script src="https://unpkg.com/jsbarcode@latest/dist/JsBarcode.all.min.js"></script>
<script>JsBarcode("#barcode", "212313");let test = document.getElementById('barcode').getAttribute('src')console.log(test)
</script>
打印代码,使用 window.print() 打印页面上局部的数据
<script>
function print_labels(developer, sqe_person, sampling_type_display, work_address, pid) {layui.use(['form', 'layer', 'laydate', 'table', 'laytpl', 'element'], function () {var form = layui.form,layer = layui.layer,$ = layui.jquery,laydate = layui.laydate,laytpl = layui.laytpl,element = layui.element,table = layui.table,formSelects = layui.formSelects;let logistics_id = $('input[name="logistics_id"]').val()if(!logistics_id){layer.msg("请先填写物流单号！");}else{JsBarcode("#barcode", logistics_id);let barcode_res = $('#barcode').attr('src')console.log(barcode_res)var headstr = "<html><head></head><body>";var footstr = "</body>";//获得 print_div 里的所有 html 数据(把要打印的数据嵌套在 一个 div 里，获得 div)//var printData = document.getElementById("print").innerHTML;var printData = `<div class="table-div" style="display: block;width: 300px; height: 241px; margin: auto;"><table border="1" cellspacing="0" cellpadding="3" style=" width: 300px; height: 230px;"><tr><td colspan="2" height="80px"><div style="text-align: center"><img id="barcode" src="${barcode_res}"/></div></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">开发员：${developer}</span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">SQE工程师：${sqe_person}</span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px"> 取样类型：${sampling_type_display} </span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px"> 收货地址：${work_address} </span></td></tr><tr><td colspan="2" height="25px"><span style="float: left;position: relative;left:3px;font-size: 16px">建资料流水号：${pid}</span></td></tr></table></div>`//获取当前页面的htmlvar oldstr = document.body.innerHTML;//把 headstr+printData+footstr 里的数据 复制给 body 的 html 数据 ，相当于重置了 整个页面的 内容document.body.innerHTML = headstr + printData + footstr;//使用方法为 window.print() 打印页面上局部的数据window.print();document.body.innerHTML = oldstr;setTimeout("parent.layer.closeAll(\"iframe\")", 1000);// parent.layer.closeAll("iframe");}});}
