出于某种奇怪的原因，iFrame在通过JavaScript更新时没有显示正确的内容。这是非常相同的链接，但结果不同

出于某种原因，您的符号是&；就让他们&。看起来静态代码在内部解决了这个问题，但是javascript没有

document.getElementById("link").src = 
'//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ac&ref=tf_til&ad_type=product_link&tracking_id=ow-20&marketplace=amazon&region=US&placement=B004BCXAM8&asins=B004BCXAM8&linkId=SK5UG2J5CK4WNOKE&show_border=true&link_opens_in_new_window=true'

在JSFIDLE中，我在两个iframe中都没有看到内容。应该有什么？@firefoxuser-1第一个有睫毛膏，来自Amazon我如何用JavaScript替换它们？我需要JavaScript来完成所有工作，而不是手动替换每个&

document.getElementById（“link”）.src=（'//ws na.amazon adsystem.com/widgets/q？ServiceVersion=20070822&；OneJS=1&；Operation=GetAdHtml&；MarketPlace=US&；source=ac&；ref=tf\u-til&；ad\u-type=product\u-link&；tracking\u-id=ow-20&；MarketPlace=amazon&；region=US&；placement=B004BCXAM8&；asins=B004BCXAM8&；linkId=SK5UG2J5CK4WNOKE&；show&；border=true&；link\u在新开业_window=true'）。替换（/amp；/g，”）；

O.O这是一个很好的注释：p为什么不编辑您的答案，和/或添加一个提琴呢？

document.getElementById("link").src = 
'//ws-na.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&OneJS=1&Operation=GetAdHtml&MarketPlace=US&source=ac&ref=tf_til&ad_type=product_link&tracking_id=ow-20&marketplace=amazon&region=US&placement=B004BCXAM8&asins=B004BCXAM8&linkId=SK5UG2J5CK4WNOKE&show_border=true&link_opens_in_new_window=true'
