uni-app electronic signature function

Foreword With the development of the times, the previous handwritten signatures have gradually derived electronic signatures, such as electronic signatures in systems such as DingTalk, and electronic signatures have the same legal effect as paper handwritten signatures. How do we implement electronic signatures as a front end? In fact, an important auxiliary tag has appeared […]

[Vue/Js] Realize a complete runnable instance of h5 signature through the jSignature plug-in, two instances of horizontal screen and vertical screen (complete code, run directly)

1. Plug-in installation: http://willowsystems.github.io/jSignature/#/about/ 2. Vertical screen example Note: # #signature {} in css corresponds to the initialization jSignature plugin $sigdiv.jSignature({}) in js, this is a trap! There are many people on the Internet who have clarified this pit. #signature { border: 2px solid #000; /* set border */ border-radius: 4px; /* Set border rounded […]
