Asp.net Mvc Html Helper listboxFor click event

如何解决Asp.net Mvc Html Helper listboxFor click event

当用户在 asp.mvc 5 中单击时如何调用 onclick。下面的代码不起作用

   @Html.ListBoxFor(m => Model.DepDashTaskLists[i].BusinessRuleQuestion1Answer,new MultiSelectList(slh.GetRegistrationAnswerLookup(Model.DepDashTaskLists[i].BusinessRuleQuestion1),"Value","Text",Model.DepDashTaskLists[i].BusinessRuleAnswers),new { @onclick="somefunction()",@id = "RuleQuestionListBoxAnswer",@class = "listBox" })

解决方法

有一些 javascript 监听 listbox 上的点击事件并获取项目文本并设置为另一个文本框的值

@Html.ListBoxFor(x => x.ItemId,new MultiSelectList(Model.ListOfItems,"Text","Value",Model.ItemId),new { size = 6,id = "itemsList",OnChange = "showText" })
$(function(){

  $("#ItemId option").click(function () {
    var _this = $(this);
    $("#txtItem").val($(_this).text());
  });

});
