I found a more useful method of operating iframe parent-child pages, record it


1. Parent page test.html



Get iframe var oframe = document. getElementById("main")


Get the subpage var child = oframe.contentWindow.document


Get the subpage Element var test = child.getElementById("test")


Get the child page height var childh = child .body.offsetHeight


Get the sub-page height


2. Sub-page iframe.html



Get the parent page var parent = window.parent.document


Note: The code needs to be placed on the server side to be compatible with Google Chrome
