真搞笑的事。

use this instead:       alert(document.getElementById("i_n_content").document.body.value);
       alert(document.getElementById("i_n_content").document.body.outerHTML);
       alert(document.getElementById("i_n_content").document.body.innerHTML);

window.i_n_content.focus();
       alert(document.Form1.frames["i_n_content"].document.body.value);
        alert(document.Form1.frames["i_n_content"].document.body.outerHTML);
        alert(document.Form1.frames["i_n_content"].document.body.innerHTML);。。}

帮忙改改吧。上面的都试了。

debugger; 单调下,问题往往都是由粗心造成的

frames["i_n_content"].document 有东西。。但是.body就NULL了。。奇怪的问题。

调试易

真搞笑的事。
