iframe实用操作锦集

//需要使用Jquery
$(document).ready(function () {
parent.document.getElementById("ifPage").style.height = document.body.scrollHeight + "px";
});

//需要使用Jquery
$(window).resize(function () {
var webheight = document.body.clientHeight - X; //X是需要减去的高度量，例如顶部导航的高度
$("#ifPage").attr("style", "height:" + webheight + "px;");
});
$(window).load(function () {
var webheight = document.body.clientHeight - 105;
$("#ifPage").attr("style", "height:" + webheight + "px;");
});

//根据iframe的id获取对象
var i1 = window.frames['iframeId'];
//var iframe =window.frames[0];也可以
//获取iframe中的元素值
var val=i1.document.getElementById("t1").value

var val = parent.document.getElementById("txt1");

var i1 = parent.window.frames['iframeId'];
var val = i1.document.getElementById("text1").value;

function parentReload() { window.parent.location.reload();}

iframe.Attributes[ "Src"] = "ItemTQEditorPage.aspx";
