pdfmake angular

Softhinker.com · 技术社区 · 7 年前

"scripts": [
    "../node_modules/pdfmake/build/pdfmake.js",
    "../node_modules/pdfmake/build/vfs_fonts.js"
  ]

然后在app.component中。ts,我是这样使用的:

import * as pdfMake from 'pdfmake';

@Component({
selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
   pdf: any;
   downloadPdf() {
    let item = {firstName: 'Peter', lastName: 'Parker'};
    this.pdf = pdfMake;
    this.pdf.createPdf(buildPdf(item)).open();
  }
}

function buildPdf(value) {
   var pdfContent = value;
   var docDefinition = {
     content: [{
    text: 'My name is: ' + pdfContent.firstName  + ' ' + pdfContent.lastName + '.'
     }]
   }
   console.log(pdfContent);
   return docDefinition;
}

加载应用程序时,我在浏览器控制台中遇到以下错误:

Uncaught TypeError: fs.readFileSync is not a function
at Object.<anonymous> (linebreaker.js:15)
at Object.<anonymous> (linebreaker.js:161)
at Object.../../../../linebreak/src/linebreaker.js (linebreaker.js:161)
at __webpack_require__ (bootstrap b937441â¦:54)
at Object.../../../../pdfmake/src/textTools.js (textTools.js:4)
at __webpack_require__ (bootstrap b937441â¦:54)
at Object.../../../../pdfmake/src/docMeasure.js (docMeasure.js:4)
at __webpack_require__ (bootstrap b937441â¦:54)
at Object.../../../../pdfmake/src/layoutBuilder.js (layoutBuilder.js:7)
at __webpack_require__ (bootstrap b937441â¦:54)

复制pdfmake。js和vfs_字体。js到assets文件夹,然后将其添加到index.html:

<script src='assets/pdfmake.min.js'></script>
<script src='assets/vfs_fonts.js'></script>

import * as pdfMake from 'pdfmake';

并将其添加到app.component.ts:

declare var pdfMake: any;

"../node_modules/pdfmake/build/pdfmake.js",
"../node_modules/pdfmake/build/vfs_fonts.js"

这是可行的,但仍然是一个解决办法。

第一

npm install pdfmake --save

其次,在typings.d.ts中添加以下内容:

declare module 'pdfmake/build/pdfmake.js';
declare module 'pdfmake/build/vfs_fonts.js';

import * as pdfMake from 'pdfmake/build/pdfmake.js';
import * as pdfFonts from 'pdfmake/build/vfs_fonts.js';
pdfMake.vfs = pdfFonts.pdfMake.vfs;

最后,使用pdfMake。xxx()和往常一样。

不 .angular-cli.json 和在TS文件中添加导入。看看 Global scripts

一旦通过脚本数组导入库,您应该不

(没有输入 pdfmake 因此,在卸载配置文件时,您需要声明它们。)

所以如果你想把它添加到你的TS文件中…替换你的 import * as pdfMake from 'pdfmake'; (它是服务器端版本!)使用客户端版本( 'pdfmake/build/pdfmake' 'pdfmake/build/vfs_fonts' )否则你也会出错。

当您的导入看起来像这样时,它应该可以工作:

import pdfMake from 'pdfmake/build/pdfmake';
import pdfFonts from 'pdfmake/build/vfs_fonts';
pdfMake.vfs = pdfFonts.pdfMake.vfs;

Stories Global Scripts 如果你仔细遵循说明。如果图书馆没有打字机。

"scripts": [
  "../node_modules/pdfmake/build/pdfmake.min.js",
  "../node_modules/pdfmake/build/vfs_fonts.js"
],

关于src/typings.d.ts文件

添加 declare var pdfMake: any; 下面的行。

pdfMake 全局变量现在可用。

ngOnInit() { console.log(pdfMake); }

输出

{
    createdPdf: f(t),
    vfs: {
        Roboto-Italic.ttf: "some long encoded string...",
        Roboto-Medium.ttf: "some long encoded string...",
        Roboto-MediumItalic.ttf: "some long encoded string...",
        Roboto-Regular.ttf: "some long encoded string...",
    }
}

这意味着它可以随时使用。

npm i pdfmake;

import * as pdfMake from 'pdfmake/build/pdfmake';
import * as pdfFonts from 'pdfmake/build/vfs_fonts';

pdfMake.vfs = pdfFonts.pdfMake.vfs;
  var dd = {
    content: [
      {
        layout: 'lightHorizontalLines', // optional
        table: {
          // headers are automatically repeated if the table spans over multiple pages
          // you can declare how many rows should be treated as headers
          headerRows: 1,
          widths: [ '*', 'auto', 100, '*' ],

          body: [
            [ 'First', 'Second', 'Third', 'The last one' ],
            [ 'Value 1', 'Value 2', 'Value 3', 'Value 4' ],
            [ { text: 'Bold value', bold: true }, 'Val 2', 'Val 3', 'Val 4' ]
          ]
        }
      }
    ]
  };
pdfMake.createPdf(dd).download();
