 document.form1.select1[1].selected="1"

var iframes=ie.document.getElementsByTagName("IFRAME");
var iframeDocument = iframes[0].contentDocument || iframes[0].contentWindow.document;

Internet Explorer uses the contentWindow property of the iframe object.
Most other browsers uses the contentDocument property.

ツールチップを表示する方法

オブジェクトではなくプロパティ自信を消してる。
JavaScript の変数と delete 演算子

JavaScriptの配列の要素を削除する(delete演算子とspliceメソッド)
a.splice(i,1); // OK

JavaScriptで指定したオブジェクトの全てのプロパティとメソッドを表示する

for (var prop in obj){
    alert(prop + "=" + obj[prop]);
}

toFixed(桁数)

using bytefx

var x = bytefx.$position(document.getElementById('ID_name')).x;
var y = bytefx.$position(document.getElementById('ID_name')).y;

var offset = $('elementID').positionedOffset(); // return an array of offsetLeft, offsetTop

var offset = Position.positionedOffset(); // return an array of offsetLeft, offsetTop

ref

position = YAHOO.util.Dom.getXY("ID_name");
