问下怎么给IFRAME 设置焦点，网上查了些方式都不行啊，设置不了。<iframe id="contents" name="contents" frameborder="0" marginheight="0" marginwidth="0" scrolling="auto"></iframe>window.onload = function()
{
var f = window.frames["contents"];
f.document.designMode="on";
f.focus(); //设置焦点无效
document.getElementById("translate_x").checked = true;
}
{
var f = window.frames["contents"];
f.document.designMode="on";
f.focus(); //设置焦点无效
document.getElementById("translate_x").checked = true;
}
要写在onload事件里才行
