js : 怎样从子窗口调用父窗口的方法

1.window.opener.jsfunction();

2.opener.location="javascript:jsfunction();“

parent.opener.document.form1.RuKuDanHao.value ;

3.通用方法

var userAgent = navigator.userAgent.toLowerCase();
var isSafari = userAgent.indexOf("Safari")>=0;
var is_opera = userAgent.indexOf('opera') != -1 && opera.version();
var is_moz = (navigator.product == 'Gecko') && userAgent.substr(userAgent.indexOf('firefox') + 8, 3);
var is_ie = (userAgent.indexOf('msie') != -1 && !is_opera) && userAgent.substr(userAgent.indexOf('msie') + 5, 3);

function getOpenner()
{
if(is_moz)
return parent.opener.document;
else
return parent.dialogArguments.document;

}

function getOpennerWindow() {
if (is_moz)
return parent.opener;
else
return parent.dialogArguments;
}
