Comment(by martinkou):
Is there any reason the *trim functions are written like this?
{{{
trim : (function()
{
// We are not using \s because we don't want "non-breaking
spaces" to be caught.
var trimRegex = /(?:^[ \t\n\r]+)|(?:[ \t\n\r]+$)/g;
return function( str )
{
return str.replace( trimRegex, '' ) ;
};
})(),
/**
* Remove spaces from the start (left) of a string. The following
* characters are removed: space, tab, line break, line feed.
* @param {String} str The text from which remove the spaces.
* @returns {String} The modified string excluding the removed
spaces.
* @example
* alert( CKEDITOR.tools.ltrim( ' example ' ); // "example "
*/
ltrim : (function()
{
// We are not using \s because we don't want "non-breaking
spaces" to be caught.
var trimRegex = /(?:^[ \t\n\r]+)/g;
return function( str )
{
return str.replace( trimRegex, '' ) ;
};
})(),
/**
* Remove spaces from the end (right) of a string. The following
* characters are removed: space, tab, line break, line feed.
* @param {String} str The text from which remove the spaces.
* @returns {String} The modified string excluding the removed
spaces.
* @example
* alert( CKEDITOR.tools.ltrim( ' example ' ); // " example"
*/
rtrim : (function()
{
// We are not using \s because we don't want "non-breaking
spaces" to be caught.
var trimRegex = /(?:[ \t\n\r]+$)/g;
return function( str )
{
return str.replace( trimRegex, '' ) ;
};
})()
}}}
There's no question it works, but they can certainly be simplified.
