x=document.getElementById("iFrameId");
x.contentDocument.getElementById("tableId");
if you can use jQuery i guess it will work across browsers
如果您可以使用 jQuery,我想它可以跨浏览器工作
$("#iFrameId").contents().find("#tableId")
$("#iFrameId").contents().find("#tableId")

You have to select the element from the iFrame's document. Per Juan's comment, check against both the name, and id of the iFrame
您必须从 iFrame 的文档中选择元素。根据 Juan 的评论,检查 iFrame 的名称和 ID
var targetFrame = window.frames["nameOfIFrame"] || window.frames["iFrameId"];
targetFrame.document.getElementById("tableId");
