iframe相互取值

1.情况：一个页面(父页面p)里加载了两个iframe子页面(fa和fb)

bgcolor="b5d6e6" onmouseover="changeto()" onmouseout="changeback()">

src="/private/membermanage/consume/consume_left.jsp">

src="/private/membermanage/consume/consume_right.jsp">

取值1：父页面获取子页面的值

var doc=window.frames["fa"].document;

var pk_goods_info = doc.getElementsByName("pk_goods_info");

var goods_quantity = doc.getElementsByName("goods_quantity");

取值2：子页面获取父页面的值，并赋值(子页面操作父页面)

var doc=parent.document;

doc.getElementById("consume_money").value=consume_money;

取值3：两个子页面相互操作(fb操作fa)

var doc= parent.frames['fa'].document;

doc.getElementById("rate"+count).value=rate;
