How to manually call functions that come with some libraries
I have installed a lightbox plugin and i would like to resue some if its functionality for other parts of my application without having to recode a separate module since it would be kind of redundant, so is it possible to reuse/share some functions from a library like say from this one
http://www.notesfor.net/samples/jquery/notesforlightbox/js/nf.lightbox.js
My intention is this light box plug in already supports hotkeys for Next, Previous, Close etc...
Here is the situation... form the lightbox.js... I want to reuse this particular function for another part of my application
(function($) {
$.fn.lightBox = function(settings) {
.... ...... ...... ..... etc ...
function _keyboard_action(objEvent) {
// To ie
if (objEvent == null) {
keycode = event.keyCode;
escapeKey = 27;
// To Mozilla
} else {
keycode = objEvent.keyCode;
escapeKey = objEvent.DOM_VK_ESCAPE;
}
// Get the key in lower case form
key = String.fromCharCode(keycode).toLowerCase();
// Verify the keys to close the ligthBox
if ((key == settings.keyToClose) || (key == 'x') || (keycode == escapeKey)) {
_finish();
}
// Verify the key to show the previous image
if ((key == settings.keyToPrev) || (keycode == 37)) {
// If we´re not showing the first image, call the previous
if (settings.activeImage != 0) {
settings.activeImage = settings.activeImage - 1;
_set_image_to_view();
_disable_keyboard_navigation();
}
}
// Verify the key to show the next image
if ((key == settings.keyToNext) || (keycode == 39)) {
// If we´re not showing the last image, call the next
if (settings.activeImage != (settings.imageArray.length - 1)) {
settings.activeImage = settings.activeImage + 1;
_set_image_to_view();
_disable_keyboard_navigation开发者_开发问答();
}
}
}
.... ...... ...... ..... etc ...
};
})(jQuery);
but if i call : _keyboard_action(objEvent) from outside, i would get an error, so what is the correct syntax to do so?
From what I understood from this post (and If I'm not misunderstood), you can simply use
<script src="NameOfJavascriptFile.js" type="text/javascript">
in your html <head> section and then call the functions like normal functions.
