Question

我目前正在开发仓库库存系统。剩下的唯一任务是如何生成和打印机架的bin ID。下面的代码只生成1个条形码。它只生成最后一个检查项。我需要一次打印多个条形码进行打印。这是link我用作生成条形码的参考。

    <?php
        require ("../../connect/db.php");
        $sql = "select * from location_bin where rack_id = 3";
        $rack   = mysqli_query($mysqli, $sql);

        while($row = mysqli_fetch_array($rack)){
            $id = $row['bin_id'];
            echo "<input type='checkbox' name='barcodeValue' id='barcodeValue' value='$id'/>$id<br>";
            }
    ?>

这是生成条形码的脚本。

<script type="text/javascript">
    function generate(){
    $(document).ready( function() {
    $("input[name=barcodeValue]:checked").each(function () {
    var id = $(this).attr("value");
    function generateBarcode(id){
    var value = id;
    var btype = $("input[name=btype]:checked").val();
    var renderer = $("input[name=renderer]:checked").val();

    var quietZone = false;
    if ($("#quietzone").is(':checked') || $("#quietzone").attr('checked')){
      quietZone = true;
    }

    var settings = {
      output:renderer,
      bgColor: $("#bgColor").val(),
      color: $("#color").val(),
      barWidth: $("#barWidth").val(),
      barHeight: $("#barHeight").val(),
      moduleSize: $("#moduleSize").val(),
      posX: $("#posX").val(),
      posY: $("#posY").val(),
      addQuietZone: $("#quietZoneSize").val()
    };
    if ($("#rectangular").is(':checked') || $("#rectangular").attr('checked')){
      value = {code:value, rect: true};
    }
    if (renderer == 'canvas'){
      clearCanvas();
      $("#barcodeTarget").hide();
      $("#canvasTarget").show().barcode(value, btype, settings);
    } else {
      $("#canvasTarget").hide();
      $("#barcodeTarget").html("").show().barcode(value, btype, settings);
    }
  }


  function showConfig1D(){
    $('.config .barcode1D').show();
    $('.config .barcode2D').hide();
  }

  function showConfig2D(){
    $('.config .barcode1D').hide();
    $('.config .barcode2D').show();
  }

  function clearCanvas(){
    var canvas = $('#canvasTarget').get(0);
    var ctx = canvas.getContext('2d');
    ctx.lineWidth = 1;
    ctx.lineCap = 'butt';
    ctx.fillStyle = '#FFFFFF';
    ctx.strokeStyle  = '#000000';
    ctx.clearRect (0, 0, canvas.width, canvas.height);
    ctx.strokeRect (0, 0, canvas.width, canvas.height);
  }

  $(function(){
    $('input[name=btype]').click(function(){
      if ($(this).attr('id') == 'datamatrix') showConfig2D(); else showConfig1D();
    });
    $('input[name=renderer]').click(function(){
      if ($(this).attr('id') == 'canvas') $('#miscCanvas').show(); else $('#miscCanvas').hide();
    });
    generateBarcode(id);
  });
});
});
}
</script>

以下是HTML代码。
