例如多选框如下:

<div class="layui-form">
<select xm-select="city">
</select>
</div>

  动态加载:

var url = "加载路径";
View.get(url, "city=" + city, function(resp) {
  if (resp) {
    var html = "";
    for (var i = 0; i < resp.length; i++) {
      html += "<option value='" + resp[i].key + "'>" + resp[i].value +"</option>";
    }
    $("select[xm-select='city']").html(html);
}
layui.formSelects.render();// 重新渲染多选框
}, function() {
});

  重新渲染多选框:

layui.formSelects.render();

  例如多选框如下:

<div class="layui-form">
<select name="city" xm-select="city_2">
<option value="1" selected="selected">北京</option>
<option value="2">上海</option>
<option value="3">广州</option>
<option value="4">深圳</option>
<option value="5">天津</option>
</select>
</div>

  禁用:

$("select[xm-select='city_2']").attr("disabled", "disabled");
layui.formSelects.render();

  启用:

$("select[xm-select='city_2']").attr("disabled", false);
layui.formSelects.render();

  赋值:

layui.formSelects.value('city_2', []);          //赋值空数组, 清空所有
layui.formSelects.value('city_2', [1, 2]); //赋值 北京,上海
layui.formSelects.value('city_2', [5], true); //追加赋值 天津
layui.formSelects.value('city_2', [1], false); //删除 已选择 [北京]

  取值:

layui.formSelects.value('city_2');              //取值默认数组
layui.formSelects.value('city_2', 'val'); //取值val数组
layui.formSelects.value('city_2', 'valStr'); //取值val字符串
layui.formSelects.value('city_2', 'name'); //取值name数组
layui.formSelects.value('city_2', 'nameStr'); //取值name字符串

  取值结果:

  取值默认数组:[{"name":"北京","value":"1"}]

  取值val数组:["1"]

  取值val字符串:"1"

  取值name数组:["北京"]

  取值name字符串:"北京"
