jQuery-检测选择对象是否已添加或删除选项

Question

I have a <select> object on the form. There are several methods in the app that can add and remove <option>'s to this <select> box.

I would like to detect when this add/remove happens. Not when an <option> has been selected (I know how to do this already).

Answer 1

try with the onChange method $("").onChange(); and this can solve your question

Answer 2

$("#yourSelectElement").on("DOMNodeInserted", function() {
  // Code here
});
