我在这里使用jspdf。

在下载pdf时，我得到一个空白页面。

当你点击submit1按钮图表将生成，当你按下载按钮这些图表将被下载为pdf格式。

一切都正常，但最后还是出现了一张空白的页面。

这是我的 live demo in plunker 。这里还有html和javascript代码。

html

<div><img id="logo" style="width:30%" src="https://www.gstatic.com/webp/gallery3/3.png"/>dddddddd</div>
 <input type="button" id="download"  value="download" /> click to console
  <div><button id="button1" class="button1">submit1</button></div>
  <p id="bottom-content">footer</p>

脚本

$(document).ready(function() {
    var index = 0;
    var id = [];
    $('#button1').on('click', function() {
        $('body').append($("<div id='chart" + index + "'></div>"));
        Highcharts.chart('chart' + index, {
           title: {
        text: 'Chart-'+index+''
            series: [{
                data: [1, 2, 3]
        var temp = "chart" + index + "";
        console.log(temp);
        id.push(temp);
        index++;
