i18n-jqueryui-button.js

// Adds support for data-i18n and data-i18n-options to jQuery UI Buttons:
if( $.fn.button ) {	// Checks the presence of the button component of jQuery UI
	// Keep a reference to the original _create function:
	var button_create_orig = $.ui.button.prototype._create;
	$.ui.button.prototype._create = function( ) {
		button_create_orig.apply( this, arguments );
		if( this.type === "button" ) {	// Not needed for input, radio or checkbox
			var data_i18n = this.buttonElement.attr( "data-i18n" ),
				i18n_options = this.buttonElement.data( "i18n-options" );
			// If found, apply the attribute and datas to the button label:
			if( data_i18n || i18n_options ) {
				var elementButtonText = this.buttonElement.find( ".ui-button-text" );
				this.buttonElement.removeAttr( "data-i18n" ).removeData( "i18n-options" );
				if( data_i18n ) elementButtonText.attr( "data-i18n", data_i18n );
				if( i18n_options ) elementButtonText.data( "i18n-options", i18n_options );
			}
		}
	};
	// Keep a reference to the original destroy function:
	var button_destroy_orig = $.ui.button.prototype.destroy;
	$.ui.button.prototype.destroy = function( ) {
		if( this.type === "button" ) {
			var elementButtonText = this.buttonElement.find( ".ui-button-text" ),
				data_i18n = elementButtonText.attr( "data-i18n" ),
				i18n_options = elementButtonText.data( "i18n-options" );
			// If found, apply the attribute and datas to the button element:
			if( data_i18n ) this.buttonElement.attr( "data-i18n", data_i18n );
			if( i18n_options ) this.buttonElement.data( "i18n-options", i18n_options );
		}
		button_destroy_orig.apply( this, arguments );
	};
}
