vue實現導出Word文件(數據流方式)

Posted on by

jquery.wordexport.js，通過該插件可以導出文本和圖片，圖片通過canvas的形式繪制，文本則需要依賴FileSaver.js插件。

FileSaver.js插件則主要通過H5的文件操作新特性new Blob()和new FileReader()來實現文本的導出。

第一步：安裝依賴：jquery 和file-saver

npm install  jquery  file-saver --save

第二步：新增jquery.wordexport.js

在src下的assets中新增js文件夾，新增jquery.wordexport.js文件

// 導入js文件
import $ from 'jquery'
import saveAs from 'file-saver'
if (typeof $ !== "undefined" && typeof saveAs !== "undefined") {
  (function ($) {
    $.fn.wordExport = function (fileName) {
      fileName = typeof fileName !== 'undefined' ? fileName : "jQuery-Word-Export";
      var statics = {
        mhtml: {
          top: "Mime-Version: 1.0\nContent-Base: " + location.href + "\nContent-Type: Multipart/related; boundary=\"NEXT.ITEM-BOUNDARY\";type=\"text/html\"\n\n--NEXT.ITEM-BOUNDARY\nContent-Type: text/html; charset=\"utf-8\"\nContent-Location: " + location.href + "\n\n<!DOCTYPE html>\n<html>\n_html_</html>",
          head: "<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">\n<style>\n_styles_\n</style>\n</head>\n",
          body: "<body>_body_</body>"
        }
      };
      var options = {
        maxWidth: 624
      };
      // Clone selected element before manipulating it
      var markup = $(this).clone();
      // Remove hidden elements from the output
      markup.each(function () {
        var self = $(this);
        if (self.is(':hidden'))
          self.remove();
      });
      // Embed all images using Data URLs
      var images = Array();
      var img = markup.find('img');
      for (var i = 0; i < img.length; i++) {
        // Calculate dimensions of output image
        var w = Math.min(img[i].width, options.maxWidth);
        var h = img[i].height * (w / img[i].width);
        // Create canvas for converting image to data URL
        var canvas = document.createElement("CANVAS");
        canvas.width = w;
        canvas.height = h;
        // Draw image to canvas
        var context = canvas.getContext('2d');
        context.drawImage(img[i], 0, 0, w, h);
        // Get data URL encoding of image
        var uri = canvas.toDataURL("image/png/jpg");
        $(img[i]).attr("src", img[i].src);
        img[i].width = w;
        img[i].height = h;
        // Save encoded image to array
        images[i] = {
          type: uri.substring(uri.indexOf(":") + 1, uri.indexOf(";")),
          encoding: uri.substring(uri.indexOf(";") + 1, uri.indexOf(",")),
          location: $(img[i]).attr("src"),
          data: uri.substring(uri.indexOf(",") + 1)
        };
      }
      // Prepare bottom of mhtml file with image data
      var mhtmlBottom = "\n";
      for (var j = 0; j < images.length; j++) {

        mhtmlBottom += "Content-Location: " + images[j].location + "\n";
        mhtmlBottom += "Content-Type: " + images[j].type + "\n";
        mhtmlBottom += "Content-Transfer-Encoding: " + images[j].encoding + "\n\n";

      var blob = new Blob([fileContent], {

      });
      saveAs(blob, fileName + ".doc");
    };
  })($);
} else {
  if (typeof $ === "undefined") {
    console.error("jQuery Word Export: missing dependency (jQuery)");
  }
  if (typeof saveAs === "undefined") {
    console.error("jQuery Word Export: missing dependency (FileSaver.js)");
  }
}

第三步：組件使用

註意：隻能寫行內樣式

<template>
  <div class="home">
    <button @click="exportWord">導出</button>
    <div id="word_demo">
      <p style="font-size:20px;color:red;">評標區</p>
      <h1 style="font-size:20px;color:blue;">標題</h1>
      <img alt="Vue logo" src="../assets/logo.png" />
    </div>
  </div>
</template>
import $ from 'jquery'
require('@/assets/js/jquery.wordexport')
export default {
  name: 'Home',
  methods: {
    exportWord() {
      setTimeout(function() {
        $('#word_demo').wordExport('word文檔')
      }, 300)
    },
  },
}

vue導出word文檔（包括圖片）

1.安裝依賴

-- 安裝 docxtemplater
npm install docxtemplater pizzip  --save
-- 安裝 jszip-utils
npm install jszip-utils --save 
-- 安裝 jszip
npm install jszip --save
-- 安裝 FileSaver
npm install file-saver --save

2.創建exportFile.js（導出word方法）

import PizZip from 'pizzip'
import docxtemplater from 'docxtemplater'
import JSZipUtils from 'jszip-utils'
import { saveAs } from 'file-saver'

  }

  let binaryString;
  if (typeof window !== "undefined") {

  const bytes = new Uint8Array(len);
  for (let i = 0; i < len; i++) {
    const ascii = binaryString.charCodeAt(i);
    bytes[i] = ascii;
  }
  return bytes.buffer;
}

3.組件調用

<template>
  <a-form-model
    ref="ruleForm"
    :model="form"
    :rules="rules"
    :label-col="labelCol"
    :wrapper-col="wrapperCol"
  >
    <a-form-model-item label="名稱" prop="name">
      <a-input-number v-model="form.name" style="width:100%;"/>
    </a-form-model-item>
    <a-form-model-item label="日期" prop="date">
      <a-input v-model="form.date" />
    </a-form-model-item>
    <a-form-model-item label="文件">
      <a-input v-model="form.imgUrl" read-only/>
      <a-upload name="file" :showUploadList="false" :customRequest="customRequest">
        <a-button type="primary" icon="upload">導入圖片</a-button>
      </a-upload>
    </a-form-model-item>
    <a-form-model-item label="操作">
      <a-button type="primary" icon="export" @click="exportWordFile">導出word文檔</a-button>
    </a-form-model-item>
  </a-form-model>
</template>
<script>
import {exportWord} from '@/assets/js/exportFile.js'
export default {
  name: 'ExportFile',
  data () {
    return {
      labelCol: { span: 6 },
      wrapperCol: { span: 16 },
      form: {},
      rules: {
        name: [
          { required: true, message: '請輸入名稱！', trigger: 'blur' },
        ],
        date:[
          { required: true, message: '請輸入日期！', trigger: 'blur' },
        ],
      },
    };
  },
  created (){},
  methods: {
    customRequest (data){
      //圖片必須轉成base64格式
      var reader = new FileReader();
      reader.readAsDataURL(data.file);
      reader.onload = () => {
        // console.log("file 轉 base64結果：" + reader.result);
        this.form.imgUrl = reader.result; //imgUrl必須與模板文件裡的參數名一致
      };
      reader.onerror = function (error) {
        console.log("Error: ", error);
      };
    },
    exportWordFile (){
      let imgSize = {
        imgUrl:[65, 65], //控制導出的word圖片大小
      };
      exportWord("./static/test.docx", this.form, "demo.docx", imgSize);
      //參數1：模板文檔 
      //參數2：字段參數
      //參數3：輸出文檔
      //參數4：圖片大小
    }
  },
};
</script>

4.創建test.docx文檔模板。註：使用vue-cli2的時候，放在static目錄下；使用vue-cli3的時候，放在public目錄下。

模板參數名需與字段一致，普通字段：{字段名}，圖片字段：{%字段名}

文檔內容：

5.導出demo.docx結果

以上為個人經驗，希望能給大傢一個參考，也希望大傢多多支持WalkonNet。
