Question

您好我正在使用select2插件进行下拉列表。我试图在开放事件上将宽度设置为不同的值，但没有成功。有没有办法以更方便的方式实现这一目标？

        $('#select').select2({
            width: o.width,
            data: objs // some data
        });

        $('$select').on('select2:open', function (e) {
            $(this).select2({width: 400}); // this does not work...
            // select2 is opened, handle event
        });

尝试这可能会对您有所帮助，您可以添加一个css类并将宽度设置为css ...

＆＃13;

 
$(document).ready(function() { 
    $("#ddl1").select2({dropdownCssClass : 'set_ddl_size'}); 
});

＆＃13;

#ddl1 {
    width: 100%;       
}

 .select2-drop-mask {
            width: 99%;
        }
         .set_ddl_size {
            width: 60% !important;
        }

    <select id="ddl1">

       <option value="larg">Larg Larg Larg Larg</option>
