javascript - 如何使用jspdf自动分页

Question

我可以让用户根据用户的选择添加更多行。如果我添加的行超过 9 或 10，则分页并且最后一行变成一半。我有 3 个按钮添加、删除和保存。

• 添加 - 添加更多行。
• 删除 - 减少行。
• 保存 - 另存为 pdf。

这是我的脚本，我在其中添加和删除行。

脚本:添加和删除行。

$(document).ready(function ()
    {
        $("#addMore").click(function ()
        {
            $("#customFields").append('<tr><td><input type="text" class="form-control"></td><td><input type="text" class="form-control"></td><td><input type="text" class="form-control"></td><td><input type="text" class="form-control"></td></tr>');
        });

        $("#removeRow").click(function()
        {   
            if ($('#customFields tbody tr').length== 1)
            {
                alert('Error');
            }
            else
            {
                $('#customFields tr:last').remove();
            }

        });

    });

脚本:另存为 pdf。

$("#save").click(function ()
    {
        var values = "";

            //i is the iterator and c is the control. So every elements iterates through the second input of callback function in this case the c variable. c is literally this current element in the array/

        $.each($(".form-control"), function(i, c)
        {
            values = values + $(c).val().trim(); // .trim() to remove white-space
        });

        if(values.length > 0)
        {       

            html2canvas(document.getElementById("captureMyDiv"),
            {
                onrendered: function(canvas)
                {
                    var img = canvas.toDataURL("image/png");
                    var doc = new jsPDF();
                    doc.addImage(img, 'JPEG',0,0);
                    doc.save('text.pdf');
                }
            });

        }

        else
        {
            alert('Cannot be left blank');
        }
    });
