突出显示帮助程序擦除HTML属性
[英]Highlight helper wipes HTML attributes
问题描述
From the Rails console: 
在Rails控制台中：
> content = "Lorem ipsum dolor sit <span class='class'>amet</span>."
> helper.highlight(content, "dolor")
=> "Lorem ipsum <strong class=\"highlight\">dolor</strong> sit <span class=\"class\">amet</span>."
However: 然而：
> content = "Lorem ipsum dolor sit <span id='id'>amet</span>."
> helper.highlight(content, "dolor")
=> "Lorem ipsum <strong class=\"highlight\">dolor</strong> sit <span>amet</span>."
As a matter of fact: 事实上：
> content = "Lorem ipsum dolor sit <a href='http://127.0.0.1' class='class' id='id' style='color: #ffffff;' target='_blank' name='name' title='title'>amet</a>."
> helper.highlight(content, "dolor")
=> "Lorem ipsum <strong class=\"highlight\">dolor</strong> sit <a href=\"http://127.0.0.1\" class=\"class\" name=\"name\" title=\"title\">amet</a>."
So the highlight helper seems to selectively wipe some HTML-attributes in its process, but not all. 因此，突出显示助手似乎在其过程中选择性地擦除了一些HTML属性，但不是全部。 Not that I care so much for target or style , but losing id s is rather unfortunate. 我并不是很在乎target或style ，但是不幸的是丢失id 。
Are there options I can pass into highlight to prevent this from happening? 是否有选择，我可以传递到highlight ，以防止这种情况发生？

You need to pass sanitize: false as an option: 您需要通过sanitize: false选项：
2.0.0-p247 :001 > content = "Lorem ipsum dolor sit <span id='id'>amet</span>."
=> "Lorem ipsum dolor sit <span id='id'>amet</span>."
2.0.0-p247 :002 > helper.highlight(content, 'dolor', sanitize: false)
=> "Lorem ipsum <mark>dolor</mark> sit <span id='id'>amet</span>."
The sanitize helper is documented here and most of the text helpers will sanitize the content by default. 此处记录了清理助手，默认情况下，大多数文本助手将清理内容。
