Using JQuery to remove an input and print its value

I am trying to do the following with JQuery: See if a text input has a value If it does, then make it read only or make it hidden and print the value in a div where the input was If it doesn't have a value, then it behaves as normal. I've tried using the hide() and read-only JQuery functions but it doesn't seem to be working. I can only refer to the input by its name (I can't edit the original code to add a class)

以上就是Using JQuery to remove an input and print its value的详细内容,更多请关注web前端其它相关文章!
