*说明:致电$(选择器).relCopy(选项)在元素上使用jQuery类型选择器
*在属性rel标签中定义。这定义了要复制的DOM元素。
* @example:$('a.copy')。relCopy({limit:5}); //< a href =example.comclass =copy =。phone>复制手机< / a>
*
* @param:string excludeSelector - 用于排除元素及其子元素的jQuery选择器
* @param:整数限制 - 允许的副本数。默认值:0无限制
* @param:string append - 在每个副本结尾附加HTML。默认值:删除链接
* @param:字符串copyClass - 要附加到每个副本的类
* @param:布尔值clearInputs - 用于清除每个副本的选项文本输入字段或textarea

$( .chosen-select)。selected({max_selected_options:2});
$(。selected-select)。bind(selected:maxselected,function(){alert(Maximum limit reached );});
$(。selected-select)。trigger('chosen:activate');
});


解决方案

我认为事件并未分配给新克隆的元素,即使在clone方法中指定了true属性。



无论如何,heres需要一个快速的解决方法来确保始终附加事件。

这不是完美的,但会让你在正确的方向:)

解决方案

I think events are not assigned to newly cloned elements, even though "true" attribute is specified in the clone method.

Anyway, heres a quick work-around to ensure events are always attached.

.hidden {

This isn't prefect but will put you in right direction :)
