一、官网的说明:https://select2.github.io/examples.html(Version?4.0.0

?

change?is fired whenever an option is selected or removed.

select2:open?is fired whenever the dropdown is opened.?select2:opening?is fired before this and can be prevented.

select2:close?is fired whenever the dropdown is closed.?select2:closing?is fired before this and can be prevented.

select2:select?is fired whenever a result is selected.?select2:selecting?is fired before this and can be prevented.

select2:unselect?is fired whenever a result is unselected.?select2:unselecting?is fired before this and can be prevented.

?

二、官网的使用例子:

?

  1. var $eventLog = $(".js-event-log");
  2. var $eventSelect = $(".js-example-events");
  3. ?
  4. $eventSelect.on("select2:open",function(e){ log("select2:open", e);});
  5. $eventSelect.on("select2:close",function(e){ log("select2:close", e);});
  6. $eventSelect.on("select2:select",function(e){ log("select2:select", e);});
  7. $eventSelect.on("select2:unselect",function(e){ log("select2:unselect", e);});
  8. ?
  9. $eventSelect.on("change",function(e){ log("change");});

?

但是在实际应用中select2:close不起作用。

?

三、解决方法:

这个原因找了很久都没有找到,昨天终于发现原因了:

$("#xxx").on("select2-close", function (e) {
	
});

?

原来是select2-close,中间的不是冒号,而是 - (横杠),修改后就能使用了

?

jquery.validate.js插件也能完善校验。

$("#genders").on("select2-close", function (e) {
	$(this).valid();
});

?

?最终原因是select2的版本问题

?
