js直接下载PDF

1、前端引入js

<script type="text/javascript"
            src="${pageContext.request.contextPath}/modules/util/downDoc/html2pdf.js"></script>

2、js方法

html定义div

$("#downPrint").click(function () {
    exportPdf();

});
/*下载Pdf文件*/
function exportPdf() {
    var content = document.getElementById('div_print');
    var options = {
        margin: 10,
        filename: '拟文单.pdf',
        image: { type: 'jpeg', quality: 0.98 },
        html2canvas: { scale: 2 },
        jsPDF: { unit: 'mm', format: 'a4', orientation: 'portrait' }
    };
    html2pdf().from(content).set(options).save();
}
