我有一个Velocity模板文件,想要将它转换成pdf。在谷歌上搜索一番后,我发现了一个名叫JSPdf的框架。但是,在尝试使用它时,它报错了:"Uncaught TypeError: Cannot read property 'cells' of undefined jspdf"。
function html_to_pdf() {
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.
AJS.log(pdf)
source = $('#productcanvas')[0];
AJS.log(source)
// 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
}
};
AJS.log("Special Elements Handler")
AJS.log(specialElementHandlers)
margins = {
top: 80,
bottom: 60,
left: 40,
width: 522
};
AJS.log("Margins")
AJS.log(margins)
// 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);
}
