jsPDF fromHTML()不显示图像

Question

HTML代码：

<div id="customers" >
   <div class="">
  <div class="heading">
      <img class="form_head" src="http://dev.syntrio.in/kchr-project/images/kchr-kchr.png" alt="">
</div>
<button onclick="javascript:demoFromHTML();">PDF</button>

JS代码：

function demoFromHTML() {
    var pdf = new jsPDF('p', 'pt', 'letter');
    // source can be HTML-formatted string, or a reference
    // to an actual DOM element from which the text will be scraped.
    source = $('#customers')[0];

    // we support special element handlers. Register them with jQuery-style 
    // ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
    // There is no support for any other type of selectors 
    // (class, of compound) at this time.
    specialElementHandlers = {
        // element with id of "bypass" - jQuery style selector
        '#bypassme': function (element, renderer) {
            // true = "handled elsewhere, bypass text extraction"
            return true
        }
    };
    margins = {
        top: 80,
        bottom: 60,
        left: 40,
        width: 10000
    };
    // all coords and widths are in jsPDF instance's declared units
    // 'inches' in this case
    pdf.fromHTML(
    source, // HTML string or DOM elem ref.
    margins.left, // x coord
    margins.top, { // y coord
        'width': margins.width, // max width of content on PDF
        'elementHandlers': specialElementHandlers
    },

    function (dispose) {
        // dispose: object with X, Y of the last line add to the PDF 
        //          this allow the insertion of new lines after html
        pdf.save('Test.pdf');
    }, margins);
}

我被包含在jspdf.debug.js中。当我单击pdf按钮时，生成了pdf，但是html代码中的图像没有显示。我有一张空白的pdf。请帮我解决这个问题

Answer 1

我也遇到了同样的问题，但我的图片看不到，因为我在chrome上试过了，火狐也试过了，如果它能工作，说明代码没问题。我澄清说，我对这个主题了解不多，但是如果你想在任何浏览器中操作，你可以使用web服务器。

尝尝这个,

我将上面的html代码更改为：

<div id="customers" >
   <div class="">
  <div class="heading">
      <img class="form_head" src="base64encoded data of the  image" alt="">
</div>
<button onclick="javascript:demoFromHTML();">PDF</button>

那么它对我来说是有效的
