如何在没有数据表的情况下打印页面

Question

我正在尝试从 sql 打印数据以用于记录目的，但我使用的是数据表，因此当我尝试单击打印时，记录不会显示所有内容。它仅显示数据表第 1 页的当前数据。我将如何做？另外，当我尝试打印它时，显示屏还显示了 php.ini 的包含功能。允许使用 Javascript 解决方案。这是我的代码

        <?php include ('sidebar.php'); ?>
    <main id="playground">
    <?php include ('header.html'); ?>

    <div class="container-fluid">
      <div class="row">

          <section class="panel panel-info">
            <header class="panel-heading">
              <h4 class="panel-title">List of employees</h4>
            </header>
            <div class="panel-body">

          <?php
            include('configuration.php');
            $sql = "SELECT  firstname, lastname, status, idnumber FROM employees ORDER BY lastname ASC";
            $result = $conn->query($sql);
          ?> 
              <table class="table table-striped datatable" id="datatables" >
                <thead>

Answer 1

请使用

$('#datatables').DataTable( {
    buttons: [
        'print'
    ]
} );

请检查Document和Reference

Answer 2

使用以下 2 个函数：

function CreateTableFromObject(tblObj) {
    objHeader = JSON.parse(JSON.stringify(tblObj.buttons.exportData()))["header"];
    objRows = JSON.parse(JSON.stringify(tblObj.buttons.exportData()))["body"];

    //Check If Action Exists in Table and remove it
    var index = objHeader.indexOf('Action');
    if (index > -1) {
        objHeader.splice(index, 1);
    }

    tblToPrint = "<table style='border: 1px solid black; border-collapse: collapse;'><thead><tr>";
    $.each(objHeader, function (key, value) {
        tblToPrint += "<th style='border: 1px solid black;'>" + value + "</th>";
    });
    tblToPrint += "</tr></thead><tbody>";
    $.each(objRows, function (key, value) {
        tblToPrint += "<tr>";
        //If action exists then decrease target by 1
        if (index > -1) {
            target = value.length - 1;
        }else {
            target = value.length;
        }
        for (var i = 0; i < target; i++) {
            tblToPrint += "<td style='border: 1px solid black;'>" + value[i] + "</td>";
        }
        tblToPrint += "</tr>";
    });
    tblToPrint += "</tbody></table>";
    return tblToPrint;
}


function PrintWindowAddParts() {
        var tblObj = $("#YourTable").DataTable();
        var tblViewRMA = CreateTableFromObject(tblObj);
        var printContents = "<div class='dataTables_wrapper form-inline dt-bootstrap'>" + tblViewRMA + "</div>";
        var size = 'height=' + $(window).height() + 'px,width=' + $(window).width() + 'px';
        var mywindow = window.open('', 'PRINT', size);
        mywindow.document.write('<html><head><title>' + "My Title" + '</title>');
        mywindow.document.write('</head><body >');
        mywindow.document.write('<h4>' + "My Title" + '</h4>');
        mywindow.document.write(printContents);
        mywindow.document.write('</body></html>');
        mywindow.document.close();
        mywindow.focus();
        mywindow.print();
        mywindow.close();
        return true;
    }

您的打印功能已就绪。
