JQuery不适用于页面加载后创建的元素

您可以使用jQuery的'live()'方法向当前和将来的节点添加事件侦听器。

$(".month-selector").live('change', function(){
    setStones();
});

  $("input#thename").live("click", function(event) {
// handler for what should happen when somebody clicks on the new input field, in this case I needed a datepicker to pop up so lets get that fired. Now that the click element registered the new input object with the DOM, it can be used like a normal jQuery selector!
    $("input#thename").datepicker();
    });

尝试:

$(".month-selector").live("change", function(event) {
 // some code
});
