bootstrap-selectpicker插件的运用

1.页面中嵌入selectpicker,需要将class属性设为“selectpicker”

<select id="bankname" class="selectpicker"><option>---请选择---</option></select>

2.利用ajax填充下拉框

$(".selectpicker").selectpicker({noneSelectedText:"请选择"});    //设置初始值
$.ajax({
	url:contextPath + "/card/list",
	type:"get",
	dataType:"json",
	success:function(result){
		var cardVos = result.result;
		for(var i=0;i<cardVos.length;i++){
			var bankname = cardVos[i].bankname;
			$("#bankname").append("<option>"+bankname+"</option>");
		}
		$(".selectpicker").selectpicker("refresh");          //数据填充后必须刷新select
	},
	error:function(result){
		layer.msg(result['message']);
	}
});
