如果选择了选择框，请选中Jquery

我有3个选择框：

<div class="widget mm_select">
    <label for="ctrl_Customers_Region">Region</label>   <select name="Customers_Region" id="ctrl_Customers_Region" class="select"><option value="">No filtering</option><option value="emea" selected="">EMEA</option><option value="america">America</option><option value="apac">APAC</option><option value="global">Global</option></select></div>

<div class="widget mm_select ">

如果选择了3个选择框中的任何一个，如何进行检查

Thx

您可以找到所选且没有值“”的选项：

$（'select'）.is（'：has（option[value！=“”]：selected）

谢谢，此脚本是否适用于所有3个选择框？选择器是全局的。是的。很酷，我试过这个，但在Firefox中不起作用：if（$（'select option:selected[value！=“”]）.length）{$（'body'）.animate（{scrollTop:parseInt（$（.ce_metamodels\u frontendfilter”）.offset（）.top-320）}，2000）}你能为同样的东西制作小提琴吗？？

 if($('select option:selected[value!=""]').length ) { 
    //more than one select box is selected
 }
