Iframe学习

function changeSrc(){
var i1 = document.getElementById("iframe1");
i1.src = "http://www.kanshule.com";
}
function getText(){
//var x = document.getElementById("iframe1").contentDocument;//此法不通
var x = window.frames["iframe1"].document.body.innerHTML;
var y = window.frames["iframe1"].document.getElementById("t1").value;
alert(x+"\n"+y);
}
