插件简介

Makes the currently selected table row more visible.

This extension helps prevent mistaken data entry by making the currently selected table row more visible. Anytime an input box inside of a table is selected the entire table row gets its style changed. The goal is to make it extremely obvious which row you are currently inputting data on to reduce the chances of inputting data on the wrong row.

How it works:
The extension injects a small script that adds a 'focusin'/'focusout' event listener to the root document object.

When the 'focusin' event fires it starts at the event.target and traverses the DOM in search of a parent element. If is found it sets the inline style to a preset highlight style.

When the 'focusout' event fires it starts at the event.target and traverses the DOM in search of a parent element. If is found it clears the inline style.

Extra Details:
* The extension needs to be enabled the first time you visit a new website by clicking the extension icon and selecting `Enable Highlight Active Row on this domain` from the context menu. This allows the user to only run the extension on select websites.
* Currently has a hard set MAX_DEPTH of 5 which limits how many parents it check before stopping. This should prevent all unnecessary DOM traversing for nodes not connected to a table, but also allow some wiggle room if the input is in a or two.

Future features:
- add an options page that allows the user to set a custom highlight style
