使用 jsPDF 将整个网页保存为 PDF

Question

我需要网页上的一个按钮，它可以立即将页面保存为具有相同 @media print css 的 PDF。所以它看起来和打印页面功能一模一样。

我查看了 jsPDF 并尝试了下面的代码。但是 我在尝试 select 整个网页时遇到以下错误：

Uncaught TypeError: Cannot read property 'name' of undefined

一定在我整个网页的selection:

source = $("html").html();

我的代码：

<script>
    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 = $("html").html();

        // 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: 522
        };
        // 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);
    }
//</script>
<a href="javascript:demoFromHTML()" class="button">Save as PDF</a>

有什么想法吗？

好吧，你的 html 中有一些 rowspan 或 Colspan 尝试删除它们，它会正常工作或尝试使用这条线

while (j < tableRow.cells.length) {

而不是你的 jspdf 文件中的这个

while (j < tableRow.cells.length && headers[j] != undefined) {

使用 jsPDF 将整个网页保存为 PDF
