var ex = node;
var str = "ex"; var myIndex = ;
for (var j in ex) {
alert("" + myIndex + "、（<font color='blue'>" + typeof (eval(str + "." + j)) + "</font>）<font color='red'>" + j + "</font>" + "：");
try { alert("<font color=''>" + eval(str + "." + j) + "</font>" + "<br>"); } catch (e) { } myIndex++;
}

var str = "ex"; var myIndex = ;
for (var j in ex) { document.writeln("" + myIndex + "、（<font color='blue'>" + typeof (eval(str + "." + j)) + "</font>）<font color='red'>" + j + "</font>" + "："); try { document.writeln("<font color=''>" + eval(str + "." + j) + "</font>" + "<br>"); } catch (e) { } myIndex++; }
return;

直接显示出来（亲自试一试？）：
var node = new Image();
var NewDivNode = $("<div></div>");
var str = "node"; var myIndex = ;
for (var j in node) {try {var curStr1 = "错误"; var curStr2 = "错误"; try {curStr1 = typeof (eval(str + "." + j)); curStr2 = eval(str + "." + j);} catch (e) {}NewDivNode.append("" + myIndex + "、（<font color='blue'>" + curStr1 + "</font>）<font color='red'>" + j + "</font>" + "：");NewDivNode.append("<font color=''>" + curStr2 + "</font>" + "<br>");}catch (e) {} myIndex++;}
$("body").html(NewDivNode);
