Select2 Gimmick: Define the currently selected selected value, we give a <select class= "test1" on Select2 nodedata-selected= "2" > Look at the Red section, then we can use the following JS code when the setting is selected$ ("#select2"). Val (function () {return $ (this). Data ("selected")}). Trigger ("change");

Use Val () to receive a function, and you can take advantage of this
