jQuery("#mySelect").prepend("<option value='0' name='0'>请选择</option>");//添加静态
$.ajax({
type: "get",
url: "/Menu/SelectMenu",
dataType: "json",
success: function (userList) {
if (userList != null) {
for (var i = 0; i < userList.length; i++) {
var id = userList[i].Id;
var menuName = userList[i].MenuName;
var preMenuID = userList[i].PreMenuID;
$("#mySelect").append("<option value='" + id + "'name='" + preMenuID + "'>" + menuName + "</option>");
}
}
}
});

 我还要要在 别的事件ajax 中调用这个异步   怎么简化调用  下面红色的

$("#myModal").on("hide.bs.modal", function () {
$('#jqForm')[0].reset();
$(this).find("label.error").remove();
$("#mySelect").empty();//加载前清空下拉框

jQuery("#mySelect").prepend("<option value='0' name='0'>请选择</option>");//添加静态
$.ajax({
type:"get",
url:"/Menu/SelectMenu",
dataType: "json",
success:function(userList){
if(userList!=null){
for(var i=0;i<userList.length;i++){
var id=userList[i].Id;
var menuName=userList[i].MenuName;
var preMenuID=userList[i].PreMenuID;
$("#mySelect").append("<option value='" + id +"'name='"+ preMenuID +"'>" + menuName + "</option>");
}
}
}
});

});
