左右选择框 js插件

随着项目的进展，测试工程师在更多的浏览器中兼容性测试中，发现有些浏览器不支持option的触发事件，这就造成了先前一篇博文bootstrap 左右框多项选择示例

中左右选择框的失效，于是我就由原先的select-option结构 改成了 现在的 ul-li 结构，并写成了js插件的形式，方便以后调用和修改，并在多个浏览器测试中得到验证：

实现的页面如下：

jsp页面的修改如下：

60                     </div>

下面是调用插件的代码

$(function () {
        $.selectBox({
            ulFrom: ‘sel_all_area‘,
            ulTo: ‘sel_selected_areas‘,
            selectAll: ‘btn_select_all_area‘,
            selectSelected: ‘btn_choose_selected_area‘,
            removeAll: ‘btn_remove_all_area‘,
            removeSelected: ‘btn_remove_selected_area‘,
            selectedClass: ‘selected‘,
            quickQuery: ‘search-for-select‘
        });
    });

最后直接贴出缩写插件的代码：
