为啥世上会有这么多不同的浏览器？每次遇到js/css的浏览器兼容性问题，总是要发出这样的感叹，真希望这些个浏览器公司全部倒下，然后只留下一家(显然这是一个不可能实现的美好愿望)，言归正传，看代码吧:
iframe框架内页：
<
html
>
< head >
< title > 框架内页 </ title >
</ head >
< body >
< div >
< input id ="txt1" name ="txt1" type ="text" value ="测试" />
</ div >
</ body >
</ html >
< head >
< title > 框架内页 </ title >
</ head >
< body >
< div >
< input id ="txt1" name ="txt1" type ="text" value ="测试" />
</ div >
</ body >
</ html >
父级类：
<

function getValue(){
var ofrm1 = document.getElementById( " frame1 " ).document;
if (ofrm1 == undefined)
{
ofrm1 = document.getElementById( " frame1 " ).contentWindow.document;
var ff = ofrm1.getElementById( " txt1 " ).value;
alert( " firefox/chrome取值结果为: " + ff);
}
else
{
var ie = document.frames[ " frame1 " ].document.getElementById( " txt1 " ).value;
alert( " ie取值结果为: " + ie);
}
}
</ script >
