There are some tricks to show loading indicator when retrieving data via Ajax request using jQuery DataTables.
PDF.js is a great plug-in to display PDF files in the browser. However by default PDF.js uses 150 DPI print resolution which sometimes results in fuzzy and blurry images and text.
There are many ways to print labels on a thermal printer from a web application. But I found a tool that makes this task a breeze – QZ Tray.
Officially jQuery DataTables doesn’t support
ROWSPAN attributes for a cell in table body. I already wrote how to use ROWSPAN attribute with jQuery DataTables. Today I am going to demonstrate a trick to use
COLSPAN attribute for HTML and Ajax sourced data.
While answering questions on StackOverflow and DataTables forum I have seen a number of similar questions on how to open all child rows. Today I am going to demonstrate a couple solutions to this problem.
Back in February, 2017 I wrote about unofficial row grouping plug-in for jQuery DataTables, see jQuery DataTables: Row grouping and checkboxes.
However there is also official extension for row grouping – RowGroup. It works differently than unofficial plug-in and adds a separate parent row for a group of child rows.
I added example demonstrating how to group rows in a table powered by jQuery DataTables plug-in and display checkboxes using Checkboxes plug-in, see RowGroup page for more details.
jQuery DataTables plug-in has lots of useful extensions that let you add extra functionality. Select extension is probably one of the most popular ones providing item selection capabilities. Usually it is used to select table rows or cells but it is capable of column selection as well.
Past version of jQuery DataTables had column reordering plug-in ColReorderWithResize that also provided the ability to resize columns by clicking and dragging the point between two columns. However this plug-in was not compatible with the latest version of jQuery DataTables.
Luckily Jeff Walter updated ColReorderWithResize to make column reordering and resizing work with jQuery DataTables 1.10 and released it under MIT license.
Came across a question on StackOverflow asking on how to use KeyTable plug-in to navigate rows instead of cells. Currently KeyTable plug-in for jQuery DataTables lets you navigate cells but not rows.
Recently I needed to add drag-and-drop support for an element that contained
iframe. When mouse pointer went over
iframe dragging stopped and that wasn’t accepted.
