我想做的就是打印到pdf中找到的任何ID为＆＃34; pdf＆＃34;的内容。这必须使用JavaScript完成。 ＆＃34; pdf＆＃34;然后应该自动下载文件，文件名为＆＃34; foobar.pdf＆＃34; 我正在使用jsPDF脚本。它抛出＆＃34;未捕获的TypeError：无法读取属性＆＃39; name＆＃39;未定义＆＃34;

var pdf = new jsPDF('p', 'pt', 'letter');

答案 0 :(得分：0)
您检查了$（“＃spnorderno”）。text（）返回的内容吗？这可能是未定义的。
除此之外，你应该发布错误引发的确切位置，这很可能发生在jsPDF库中。
