需要帮助让jspdf将html呈现为PDF

Question

I'm trying to get jspdf to work. Nothing is happening after clicking the button in my fiddle. Here is the jsfiddle ( https://jsfiddle.net/light22/68h81owf/ ). Thanks in advance for helping me.

Here is the script I am using:

<script>
    function demoFromHTML() {
        var pdf = new jsPDF('p', 'pt', 'letter');

        source = $('#for_pdf')[0];

        specialElementHandlers = {

            '#bypassme': function (element, renderer) {
                return true
            }
        };
        margins = {
            top: 80,
            bottom: 60,
            left: 40,
            width: 522
        };

        pdf.fromHTML(
            source, 
            margins.left, 
            margins.top, { 
                'width': margins.width, 
                'elementHandlers': specialElementHandlers
            },

            function (dispose) {

                pdf.save('download.pdf');
            }, margins
        );
    }
</script>

After clicking the button in your jsfiddle, an error is thrown: ReferenceError: demoFromHTML is not defined . You also forgot to close the style attribute in <table>
