Question

我在ionicframework中使用pdf make plugin创建pdf并下载它工作正常但是当我添加更多动态内容时，页面不会自动中断，任何人都可以告诉我如何自动使用分页符pdf make.I尝试过使用

pageBreakBefore: function (currentNode, followingNodesOnPage) {
      return currentNode.headlineLevel === 1 && followingNodesOnPage.length === 0;
    },

但它并没有破坏页面。

代码：

var dd = {
    pageSize: 'A4',
    pageOrientation: 'portrait',
    content: [
      { text: $translate.instant('{{"billnumber_message" | translate}}') + invoice.billno, alignment: 'left', style: 'subheader'},
       { text: $translate.instant('{{"billdate_message" | translate}}') + currentbilldate, alignment: 'right', style: 'subheader'},

      { text: $translate.instant('{{"billto_message" | translate}}') + invoice.name + ',\n' + invoice.location + ',\n' + invoice.mobileno + '\n', style: 'subheader' },
      {
        style: 'itemsTable',
        table: {
          widths: ['*', '*', '*', '*'],
          body: [
            [
                { text: $translate.instant('{{"billDescription_message" | translate}}'), style: 'itemsTableHeader' },
                { text: $translate.instant('{{"billquantity_message" | translate}}'), style: 'itemsTableHeader' },

                { text: $translate.instant('{{"billtotal_message" | translate}}'), style: 'itemsTableHeader' },
            ]
          ].concat(items)
        }
      },

看起来空列是问题所在。问题更加频繁，导致测量出现问题。

实施例：您已将特定列设为空，如此

       [
          '',
          $translate.instant('{{"billtotaldebit_message" | translate}}'),
          totaldebit,
        ],

但你必须这样给：

[
          ' ',
          $translate.instant('{{"billtotaldebit_message" | translate}}'),
          totaldebit,
        ],

尝试更改已提供空字符串的所有列，并检查更多信息，请检查链接：Pdfmake autopage break issues
