window.showdialog传值问题，怎么获取不到呢

[yxwf2008]

        var siteurl="http://school.sina.com.cn";
	var arr = showModalDialog(siteurl+"/sbbs_editor/img.asp", window, "dialogWidth:440px; dialogHeight:360px; status:0; help:0");

img.asp里的返回代码：

function ReturnValue(){
	sFromUrl = d_fromurl.value;
	sAlt = d_alt.value;
	sBorder = d_border.value;
	sBorderColor = d_bordercolor.value;
	sFilter = d_filter.value;
	sAlign = d_align.value;
	sWidth = d_width.value;
	sHeight = d_height.value;
	sVSpace = d_vspace.value;
	sHSpace = d_hspace.value;

	if (sAction == "MODI") {
		oControl.src = sFromUrl;
		oControl.alt = sAlt;
		oControl.border = sBorder;
		oControl.style.borderColor = sBorderColor;
		oControl.style.filter = sFilter;
		oControl.align = sAlign;
		oControl.width = sWidth;
		oControl.height = sHeight;
		oControl.vspace = sVSpace;
		oControl.hspace = sHSpace;
	}else{
		var sHTML = '';
		if (sFilter!=""){
			sHTML=sHTML+'filter:'+sFilter+';';
		}
		if (sBorderColor!=""){
			sHTML=sHTML+'border-color:'+sBorderColor+';';
		}
		if (sHTML!=""){
			sHTML=' style="'+sHTML+'"';
		}
		sHTML = '<img src="'+sFromUrl+'"'+sHTML;
		if (sBorder!=""){
			sHTML=sHTML+' border="'+sBorder+'"';
		}
		if (sAlt!=""){
			sHTML=sHTML+' alt="'+sAlt+'"';
		}
		if (sAlign!=""){
			sHTML=sHTML+' align="'+sAlign+'"';
		}
		if (sWidth!=""){
			sHTML=sHTML+' width="'+sWidth+'"';
		}
		if (sHeight!=""){
			sHTML=sHTML+' height="'+sHeight+'"';
		}
		if (sVSpace!=""){
			sHTML=sHTML+' vspace="'+sVSpace+'"';
		}
		if (sHSpace!=""){
			sHTML=sHTML+' hspace="'+sHSpace+'"';
		}
		sHTML=sHTML+'>';
		//IframeID.document.body.innerHTML=sHTML;
		//dialogArguments.insertHTML(sHTML);
	}
	re = new makearray(3);
	re[1]=sHTML;
	re[2]=d_upfilename.value;
	re[3]=fileid.value
	
	alert(re[1]);  //这里有值的
	window.returnValue = re;
	window.close();
}

我用另一个域名的页面调用，结果却取不到值，难道是说window.showdialog不能跨域返回值？

帮顶一下`
你父窗体和子窗体不是在同一个应用里面吗？

[mengxj85]

Url传值吧

[yxwf2008]

父窗体在域名A下，子窗体是在域名B下，这样不可以么？
