将jQuery引导模式与ajax加载的内容一起使用时，加载jQuery select2时出错,jquery,twitter-bootstrap,jquery-select2,bootstrap-modal,Jquery,Twitter Bootstrap,Jquery Select2,Bootstrap Modal,我正在用AJAX加载一个。结果模式工作得很好，但是加载的框没有初始化我怎样才能修好它这是我的密码： index.php（html）： index.php（js）： $（“#选择2#u内容”）。选择2({ allowClear:对 }); content.php： A. ...

我正在用AJAX加载一个。结果模式工作得很好，但是加载的框没有初始化

我怎样才能修好它

这是我的密码： index.php（html）：

index.php（js）：

$（“#选择2#u内容”）。选择2({
allowClear:对
});

content.php：


A.
...
Z

问题如果您正在执行

$（“#select2_content”）。在初始页面加载时选择2（{}）

，则

#select2_content

尚不存在。因此jQuery表达式找不到任何东西，因此永远不会初始化选择框。那它就再也不会跑了

解决您可以执行以下任一操作：

通过ajax加载完模式后，需要点击并运行一个函数来初始化任何新元素上的select2

或者，您可以通过ajax调用中的

标记引入函数，该标记将在DOM解析通过ajax引入的代码时执行。只需确保在末尾添加script标记，或者将javascript包装到一个documentready函数中，否则它在dom中仍然不存在
