Bug & Tip

  • tip: nodes Not recommended. String Type, performance will drop.
  • tip: Masking all node events within a component.
  • tip: attrs Property is not supported id Support class.
  • tip: name Property is not case sensitive.
  • tip: If an untrusted HTML node is used, the node and all its children are removed.
  • tip: img Tags only support web pictures
  • tip: If you use the rich-text Component, then only the custom component s wxss Style pair rich-text to hit the target class Entry into force.
