EasyUI Combobox 级联查询

本文主要是介绍EasyUI Combobox 级联查询，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在维护市委组织部项目的时候，使用了级联组合框，维护的时候是Asp.net，纯三层架构+Aspx页面+ashx（一般处理程序），在重构市委组织部项目的时候，用到了ITOO的框架，在ITOO4.1项目中熟悉了基本的框架，组织部项目中搭了三次框架，对框架的理解更深刻了一些；

ITOO框架，前台使用MVC，在页面cshtml和Controller之间传值，实现级联组合框，代码和维护时候的一样；

前台页面代码：

  单位类别：<input id ="unitCategory" class="easyui-combobox" name ="cc" data-options="method:'get',valueField:'id',textField:'text',url:'/CadresRate/queryCategory',panelHeight:'auto',onSelect:function(rec)          //rec表示被选择的内容，把id值传到controller中；                          {var url ='/CadresRate/queryUnitName?id=' +rec.id ;$('#unitName').combobox('reload',url);    //重新加载单位名称的组合框；}
"/>单位名称<input id ="unitName2" class ="easyui-combobox" name ="cc" data-options="panelHeight:'auto',valueField:'id',textField:'id'" />

Controller中代码：

页面加载查询出所有的单位类别；

        #region queryCategory + 查询单位类型 范晓权 2016年2月26日/// <summary>/// 查询单位类型；/// </summary>/// <returns></returns>public JsonResult queryCategory(){//定义一个字典的ViewModelBasicDictionaryViewModel vBasicDictionary = new BasicDictionaryViewModel(){//表示设置vBasicDictionary.DictionaryType = 5DictionaryType = 5};//调用服务器的查询类型的方法；List<BasicDictionaryViewModel> basicDictionary = IBasicDictionary.queryType(vBasicDictionary);//选择字典id 和 基础信息var unitCategory = from c in basicDictionaryselect new{id = c.DictionaryName,text = c.BasicInfoType};return Json(unitCategory, JsonRequestBehavior.AllowGet);} #endregion
