Finally, I found a correct method to get the iframe sub-element! Js + jquery !, Iframejquery

Baidu has been on the Internet for a long time, and the answer is the same, and it cannot be executed ~~~ Every time an error is reported, it is not easy to find a correct one!

 

Key 1: The method should be written in iframe onload, loaded and executed. Key 2: Get the iframe element with id. The contentWindow method for getting the document Object is as follows: var iFrame = document. getElementById ('iframeid'); var icontent = iframe. contentWindow; var $ ibody = icontent. $; next, you can use $ ibody to operate the dom elements in iframe. chrome, firefox, and ie9 are all easy to use ~! E.g. $ ibody ('classname ');
