如何在select2 new / remove标签事件上触发新的ajax？

未经测试，但应该可以工作：

$('.e6').on("change", function(e){    if (e.removed) {        $.ajax({ type: "POST", url: '/admin/?controller=vouchers&action=updateRelatedProducts', data: {id: e.removed.id, action: remove},    //Or you can e.removed.text error: function () {     alert("error"); }        });    }    if (e.added) {        $.ajax({ type: "POST", url: '/admin/?controller=vouchers&action=updateRelatedProducts', data: {id: e.added.id, action: add},    //Or you can e.added.text error: function () {     alert("error"); }        });    }    //OR you can play with val data instead    if (e.val) {        $.ajax({ type: "POST", url: '/admin/?controller=vouchers&action=updateRelatedProducts', data: {val: JSON.stringify(e.val)},    //Will send all the selected values error: function () {     alert("error"); }        });    }}
