I don't know that much JQuery but I've heard it allows to fire native events with this syntax.
$(document).ready(function(){
$('#countrylist').change(function(e){
// Your event handler
});
// And now fire change event when the DOM is ready
$('#countrylist').trigger('change');
});
在调用trigger()或change()之前，必须声明更改事件处理程序，否则将不会触发它.谢谢你提到@LenielMacaferi.
