<template>
  <div>
    <!-- 其他代码 -->
    <el-button @click="handleDownload">下载PDF</el-button>
    <el-dialog :visible.sync="dialogVisible">
      <div id="content-to-pdf">
        <!-- 对话框内容 -->
      </div>
    </el-dialog>
  </div>
</template>

<script>
import html2canvas from 'html2canvas';
import { jsPDF } from "jspdf";

export default {
  data() {
    return {
      dialogVisible: false,
    };
  },
  methods: {
    handleDownload() {
      const contentDom = document.getElementById('content-to-pdf');
      
      // 使用html2canvas捕获DOM元素为图片
      html2canvas(contentDom).then(canvas => {
        const imgData = canvas.toDataURL('image/png');
        
        // 创建PDF并添加图片
        const pdf = new jsPDF();
        pdf.addImage(imgData, 'PNG', 10, 10);
        
        // 下载PDF
        pdf.save("download.pdf");
      });
    }
  }
}
