# "Find" in NW.js

Adds "Ctrl+F" find box to highlight text in the DOM

![Animated example](find-in-nw.gif)

## Use

1. `npm install --save findinnw`
1. In your HTML file add:
```html


findInNw.initialize();

```
1. Use `CTRL+F` to display and give focus to the search box
1. After typing, press `ENTER` to go to highlight/scroll to the next match.
1. Use `TAB` to navigate to the "previous", "next", and "close" buttons.
1. Use `ENTER` or `SPACE` to activate a button when focused.
1. User `ESC` to hide the search box and return focus to the body

## API

### `findInNw.initialize(options);`

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](https://github.com/padolsey/findAndReplaceDOMText#options) 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: {}
});
```

### `findInNw.showSearchBox();`

This is used to programmitcally display the search box. `CTRL+F` will still display it too.

### `findInNw.hideSearchBox();`

This is used to programmitcally hide the search box. `ESC` will still hide it too.

### `findInNw.search('Text to find');`

This is used to programmitcally find text.

### `findInNw.highlightNext();` and `findInNw.highlightPrevious();`

This will highlight and scroll to the next or previous match.

### `findInNw.clearTokens();`

This is used to remove all the highlighted tokens.

## Customizing Styles

### Highlight tokens

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;
}
```

### Search Box

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 {}
```
