Because foreground HTML has generated reports dynamically, and the foreground has a feature, a date range component, when you drag, the report changes dynamically without submitting to the background.Therefore, we need to use the JS to generate the Health report:
Components to use:
Jquery.js
jspdf.js
canvg.js
html2canvas.js
jspdf.plugin.autotable.js
Foreground dynamically generated chart is now generally used HTML5 canvas or SVG, very
tutorial on the use of the IText class library. This tutorial begins with a more systematic introduction to the methods and techniques of putting text, pictures, forms, and so on in a PDF file. After reading this tutorial, you can basically do some simple to complex PDF files. However, trying to solve all the difficulties in the process of generating PDF files through tutorials is an extravagant hope. Therefore, it is important to read the Itext API documentation. While downloading the class li
Expansion and collection of grouped aggregations in reports and techniques for dealing with irregular hierarchies (do not expand without child elements, delete + symbols)
