|
|
// Method: jQuery.fn.replaceText
|
|
//
|
|
// Replace text in specified elements. Note that only text content will be
|
|
// modified, leaving all tags and attributes untouched. The new text can be
|
|
// either text or HTML.
|
|
//
|
|
// Uses the String prototype replace method, full documentation on that method
|
|
// can be found here:
|
|
//
|
|
// https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Objects/String/Replace
|
|
//
|
|
// Usage:
|
|
//
|
|
// > jQuery('selector').replaceText( search, replace [, text_only ] );
|
|
//
|
|
// Arguments:
|
|
//
|
|
// search - (RegExp|String) A RegExp object or substring to be replaced.
|
|
// Because the String prototype replace method is used internally, this
|
|
// argument should be specified accordingly.
|
|
// replace - (String|Function) The String that replaces the substring received
|
|
// from the search argument, or a function to be invoked to create the new
|
|
// substring. Because the String prototype replace method is used internally,
|
|
// this argument should be specified accordingly.
|
|
// text_only - (Boolean) If true, any HTML will be rendered as text. Defaults
|
|
// to false.
|
|
//
|
|
// Returns:
|
|
//
|
|
// (jQuery) The initial jQuery collection of elements.
