API

$3

This is the initialization command. It must be ran once. You can pass in an options object documented below:

#### options

Option | Type | Description
:-- | :-- | :--
verbose | Boolean | Console logs information, included mutations that re-trigger searches
classesToIgnore | Array of Strings | List of class names to ignore when deciding to re-trigger searches automatically when the DOM changes
idsToIgnore | Array of Strings | List of IDs to ignore when deciding to re-trigger searches automatically when the DOM changes
passThrough | Object | Any findAndReplaceDOMText options

Note: If you notice the search box is acting funny (the "Next"/"Previous" buttons aren't working as expected for example), then most likely there are DOM changes occurring that are re-triggering the search to display accurate results. This causes the "current" highlighted item to be reset. You should turn on verbose, then look at the mutations logged when the funny behavior occurs. Each mutation has a target (the element that changed). You can add that targeted element's ID or classname to the array of classesToIgnore or idsToIgnore. This should stop the funny behavior.

Example:

`js
findInNw.initialize({
verbose: true,
classesToIgnore: ['tooltip', 'tabCount'],
idsToIgnore: ['back-to-top'],
passThrough: {}
});

Customizing Styles

$3

All highlight tokens of matching searched text will be wrapped in a searched text.

They will also contain a data-find-in-nw-position="4" data attribute, the number correlates to a zero-based index of all matches.

As you navigate from one match to the next, the currently selected match will have a class of .find-in-nw-current-token.

You can customize this by targeting the following

`css
mark.find-in-nw-token {
background-color: #00F;
}

mark.find-in-nw-current-token {
background-color: #38D878;
}
`

$3

Each element of the search box is styled by targeting a class. They also all have a matching ID that you can target to override them.

`css
/ The container for the input/count/close /
#find-in-nw-search-box {}

/ The input field you type in /
#find-in-nw-input {}

/ The current selected match number. Ex: The number 1 in "1/5" /
#find-in-nw-current {}

/ The separator between the current and count. Ex: The slash (/) in "1/5" /
#find-in-nw-of {}

/ The count of matching highlighted items. Ex: The number 5 in "1/5" /
#find-in-nw-count {}

/ The case sensitivty toggle, Ex: Aa button /
#find-in-nw-case-sensitive {}

/ The previous and next buttons, ∧ and ∨ /
#find-in-nw-previous {}
#find-in-nw-next {}

/ The × close button /
#find-in-nw-close {}
