Ligerui multi-choice dynamic drop-down box

This afternoon, I asked for an option that supports multiple choices and the plug-in uses ligerui. It was a little tricky at the time, because ligerui was never used! According to the API introduction, I also did a good job, but why is it not displayed? It is said that there is a little god who is very powerful. Please come and ask, the two points have passed, and there is still no result ...................

Okay, let's get into the question. First, we need to create a ligerui drop-down box. We must initialize a drop-down box when loading the page. Otherwise, it would be hard for you to ask your mom to come! (Well, I won't look at the API !)

First, let me talk about my current needs. I need to do something similar to secondary linkage. There are two drop-down boxes: one is the housing type, the other is the housing structure. When I select the housing type, format the house, and then... I made an onchange event in the house type ......

This is the HTML page code:

<input type="text" id="house_type" maxlength="20" onchange="show_houseType_child(this.value);"/>　　<!--房屋类型下拉框--><input type="text" id="housing_pattern"  maxlength="20"/>　　 <!--房屋格局-->

JS Code, onchang event:

//页面加载的时候必须给下拉框初始化为一个下拉框　　 
 $("#housing_pattern").ligerComboBox({
   　　data: [{value_meaning:"--请选择--",mcs_sys_dict_data_id:"-1"}], 
   　　textField: ‘value_meaning‘,　　//页面显示的文本信息
   　　valueField:‘mcs_sys_dict_data_id‘,　　//数据的id
   　　isMultiSelect: true,　　//是否支持多选
   　　isShowCheckBox: true ,　　//是否显示复选框
  　　 valueFieldID: ‘value_mean‘//value_mean只是一个名称，可以随便取名
  });


  //点击房产类型出现子菜单，没有写在页面加载中     function show_houseType_child(json){        if(combox.getValue()!=‘-1‘){            var mcs_sys_dict_id_id=combox.getValue();            $.ajax({                   type: "get",                   url: "/MCS/sysmanage/mcssysdictdatabydictidempty.do",                   data: "mcs_sys_dict_id="+mcs_sys_dict_id_id+"&isEmpty=true",　　//ajax向后台发送数据                   success: function(data){                        liger.get("housing_pattern").setData(data);　　//返回data数据，并且赋值给文本框id为：housing_pattern                   }                });         }     }

Okay, it's basically shaped. Is there any doubt that the multiple choice is coming out? What about the single choice housing type? In fact, this company has been encapsulated, and I can only stick it out, and may report an error, crying!

JS housing type single choice:

     //房产类型方法    function init_cre_loan_type(json){        var cre_loan_type_params ={                dest_url:‘/sysmanage/mcssysdictdatabydictidempty.do?isEmpty=true&mcs_sys_dict_id=56 ‘,                t_col_name:‘house_type‘,                valueField:‘mcs_sys_dict_data_id‘,   //下拉框value对应的值，默认为id                textField:‘value_meaning‘,    //下拉框text对应的值，默认为text                def_val:‘first‘                };        combox = global_ligerui_extend.initCombox("house_type",null,cre_loan_type_params);        if(json){            //把值装载设定            global_ligerui_extend.syncRequestInitComboxData(json,"house_type");            //让其不可编辑            global_ligerui_extend.disabledCombox("house_type");        }else{                        global_ligerui_extend.initComboxDefVal("house_type");        }    }

JS encapsulated by the company:
You can also create a JS file named Global. ligerui. Extend. JS, and paste it to believe that you are absolutely amazing!

I finally finished writing, but I am running a little bug. I will continue to improve it after I finish processing it.

My work starts again in a day, fight!
