Question

我正在尝试使用jsPDF将jsp代码转换为PDF文件。但它给了我 TypeError：pdf.fromHTML不是函数。我从https://github.com/MrRio/jsPDF下载了jspdf zip。我的代码是：

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.js"></script>

<script type="text/javascript">
    $(document).ready(function() {

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

Answer 1

您正在加载错误的文件。

使用Javascript库，有原始源文件，然后已准备好分发的已编译文件。因此，每当您查看此类库时，如果要查找要包含的文件，则检查 dist / 目录是很常见的。因此，您需要包含jspdf.debug.js或jspdf.min.js

存储库中包含的示例是了解如何包含和使用库的好方法。看看这里的基本示例：

Answer 2

只需使用以下依赖项。

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.debug.js"></script>

请确保，您不会包含任何其他将覆盖jspdf.debug.js文件的jspdf.js文件。包含多个版本也会导致问题。
