Question

net mvc，我想基于一些动态使用javascript动态设置Kendo Multiselect的MaxSelectedItems属性。请参阅下面的代码片段。在此先感谢。

@ Html.Kendo（）。MultiSelectFor（model =＆gt; model.Name）

在我的javascript中

if(condition)
{    
    $(#Name).MaxSelectedItems(1);
}

JS无法正常工作

Answer 1

尝试做：

if (condition) {
    var ms = $("#multiselect").data("kendoMultiSelect");
    ms.options.maxSelectedValue = 6;
}

示例：

＆＃13;

$("#required").kendoMultiSelect({
  maxSelectedItems : 4
}).data("kendoMultiSelect");

$("#change6").on("click", function() {
  var sel = $("#required").data("kendoMultiSelect");
  sel.options.maxSelectedItems = 6;
}); 
$("#change4").on("click", function() {
  var sel = $("#required").data("kendoMultiSelect");
  sel.options.maxSelectedItems = 4;
});

Answer 2

 @(Html.Kendo().MultiSelect()
            .Name("ArenaList2")
            .Placeholder("Select attendees...")
            .BindTo(Model.ArenaList)
            .DataTextField("Text")
            .DataValueField("Value")
            .MaxSelectedItems(3)
 )

您可以使用此选项 .MaxSelectedItems（3）

在控件中配置它
