jspdf / html2 может отключить данные
Я посмотрел на другие связанные вопросы, но не смог понять или изменить это, чтобы заставить его работать. В основном я пытаюсь сохранить PDF-файл представленных данных flot, содержащихся в tab0. По какой-то причине вывод pdf обрезает половину страницы, хотя я использую самый большой размер a0, и в нем также отсутствует легенда диаграмм, вот код.
(function ($) {
$(function() {
// $.plot($("#placeholder0"), [ { label: 'Test', data: [[0, 0], [1, 1]] } ], { yaxis: { max: 1 } });
$("#generate0").on("click", function(e) {
var pdf = new jsPDF('p', 'pt', 'a0');
// var pdf = new jsPDF();
var canvas = pdf.canvas;
canvas.height = 6000;
html2canvas($('#content').get(0), {
canvas:canvas,
allowTaint: true,
onrendered: function(canvas) {
// document.body.appendChild(canvas);
console.log("rendered");
/* var iframe = document.createElement('iframe');
iframe.setAttribute('style','position:absolute;right:0; top:0; bottom:0; height:10000px; width:500px');
document.body.appendChild(iframe);
iframe.src = pdf.output('datauristring'); */
pdf.save("Current Data2.pdf")
//var div = document.createElement('pre');
//div.innerText=pdf.output();
//document.body.appendChild(div);
}
});
});
});
}(jQuery))
все, что я хочу сделать, — это разрешить сохраненному PDF-файлу захватить все данные, даже если это означает, что он охватывает 3 или 10 PDF-страниц. Любая помощь с большим удовлетворением … О, вот HTML / PHP …

Решение
Я сталкиваюсь с той же проблемой, я обнаружил, что это не проблема размера страницы jsPDF, а html2canvas.
Если вы укажете параметр canvas для html2canvas, то html2canvas, вероятно, не будет захватывать элемент $('#content').get(0) по ширине он будет захватывать этот элемент по ширине всего окна, если ширина холста меньше ширины окна, захваченное изображение обрезается.
попробуй :
canvas.width = document.body.clientWidth
Это не окончательное решение, но работает для меня.
