html-filter v4.3.3
html 过滤库 A library for filtering HTML tags and attributes written in JavaScript
4.0 变化
从 4.0 开始,过滤标签时不再删除子元素,只会关注标签是否需要过滤,行为如下
// before 4.0
htmlFilter.allowedTags = { p: null, br: null };
htmlFilter.filter('<div><br /><p>hello</p></div>');
result is: ''
// 4.0 +
htmlFilter.allowedTags = { p: null, br: null };
htmlFilter.filter('<div><br /><p>hello</p></div>');
result is: '<br /><p>hello</p>'
