 [2009.02.05] 外部リンク確認メッセージ追加    (C) Resident First

関数  linkConfirm()

引数  pageName ---- 外部サイトページ運営者
      URL --------- 外部サイトURL

注意点 
極端に古いブラウザ(IE3,NN2以下）以外は、特にありません。
aタグのonClickイベントで動かせて、hrefはvoid(0)をかけたほうが親切です

サンプル
<a href="javascript:void(0);" onClick="linkConfirm('Yahoo!' , 'http://www.yahoo.co.jp/' )">
---------------------------------------------------------------*/
function linkConfirm( pageName , URL ){
	var cfm = confirm(pageName + "のサイトにリンクします");
	if (cfm){
		var win=window.open( URL )
		win.focus();
	}
}
