当iframe没有ID时，向父级隐藏iframe中的元素 [英] hide elements in an iframe from the parent when the iframe has no id

问题描述

网址为 http://oxfordgenetics.com/plasmid-builder ，而iframe来自每个构建器组上的产品详细信息"链接.我需要做的是隐藏单击此链接时出现的阴影框中的某些元素.

The url is http://oxfordgenetics.com/plasmid-builder and the iframe comes from the "product details" link on each builder group. What I need to do is hide some of the elements in the shadowbox that appears when this link is clicked.

我尝试了所有常用的补救措施(jQuery和js)都没有成功，因为大多数补救措施都是使用此处不存在的ID锁定到iframe上的.

I have tried all of the usual remedies (both jQuery and js) without success as most of them latch onto the iframe using its ID which doesn't exist here.

当然是同一域.

推荐答案

我通过下面的代码来测试它是否为模态"框，而不是仅在模态"窗口中具有任意ID的方法来解决:

I got around it by having the code below test if it was a 'modal' box or not with an arbitrary ID that was only in the 'modal' window:

var element = document.getElementById('system-message-container'); 
if (typeof(element) != 'undefined' && element != null)
{
       document.getElementById('cartarea').style.display='none';
}
