//通过这样即可获取iframe中的元素 document.getElementById("myFrame").contentWindow.document.getElementById('ss').innerHTML; // 等价于 window.frames[0] // is the same thing as document.getElementsByTagName("iframe")[ 0 ].contentWindow
var frames = window.frames; // or // var frames = window.parent.frames; for (var i = 0; i < frames.length; i++) { // do something with each subframe as frames[i] frames[i].document.body.style.background = "red"; }
window.onload = (function () { var iObj = document.getElementById('iId').contentWindow; alert(iObj.document.getElementsByTagName('h1')[0].firstChild.data); }); //此方法经过ie6,ie7,firefox2.0,firefox3.0测试都通过
// firefox下访问操作iframe里内容 var iObj = document.getElementById('iId').contentDocument; alert(iObj.getElementsByTagName('h1')[0].innerHTML='我想变成她一天的一部分'); alert(iObj.getElementsByTagName('p')[0].firstChild.data);
//通过designMode(设置文档为可编辑设计模式)和contentEditable(设置内容为可编辑),你可以重写iframe里的内容。代码: var iObj = document.getElementById('iId').contentWindow; iObj.document.designMode = 'On'; iObj.document.contentEditable = true; iObj.document.open(); iObj.document.writeln('<html><head>'); iObj.document.writeln('<style>body {background:#000;font-size:9pt;margin: 2px; padding: 0px;}</style>'); iObj.document.writeln('</head><body></body></html>'); iObj.document.close();
