<select name="alddlname" id="alddl" 
    data-bind="
        options: authorityLevel,optionsText: 'AuthorityLevel',optionsValue: 'aid',value: aid
    ">
</select>

我将链接到使用所选项目并将其传递给模型属性

public List<authorityLevel> authLevellistItems { get; set; }
public string SelectedAuthType { get; set; }

我想将模型绑定到下拉列表,以便将selectedAuthType设置为该值

这个下拉列表是从淘汰赛中推出的

var authorityLevelList = Html.Raw(JsonConvert.SerializeObject(ViewBag.authorityLevelDDL));
 
$(document).ready(function ()
{
    var vm = new App@R_404_93@l();            
    vm.authorityLevel = ko.mapping.fromJS(@authorityLevelList);
    ko.applyBindings(vm);
});

先感谢您
