结合custWatchs函数调用自定义查询

业务场景：

当某些组件不支持自定义查询时，那我们通过js脚本的custWatchs函数去调用自定义查询

实现方式

第一步：配置一个自定义查询

第二步：切换到js脚本，鼠标放到custWatchs函数这里，去点击调用自定义查询

第三步：设置条件和返回值的绑定值

//页面自定义观察函数{name:"data.字段",action:function(){}}
var custWatchs=[{name:"data.yjhd",action:function(val){
 var self_=this;
 var main=self_.data;

/**
 * @param F_HDLX varchar
 */ 
this.invokeCustomQuery("chax",{"F_HDLX":main.htlx,"REF_ID_":JSON.parse(val).value},function(data){
   //返回的数据 data:[{F_SYB_NAME,F_JXSMC,F_KSSJ,F_JSSJ,F_JHYF,F_SGYTCL,F_HDLX,F_WLMTHJZE,F_CZHJJE,F_SQJE,F_SPJE,F_hdlx,F_hdmc,F_cx,F_kssj,F_jssj,F_sl,F_dj,F_zk,F_je,F_HDLX_NAME}]

 for(var i=0;i<data.length;i++){
 var row=data[i];
   main.syb=row.F_SYB_NAME;
   main.jxsmc=row.F_JXSMC;
   main.jhyf=row.F_JHYF;
   main.sgytcl=row.F_SGYTCL;
   var subrow={}

   subrow.hdmc=row.F_hdmc;
   subrow.cx=row.F_cx;
   var kssj = new Date(row.F_kssj);
   subrow.kssj=(kssj.getFullYear()) + "-" + (kssj.getMonth() + 1) + "-" + (kssj.getDate());
   var jssj=new Date(row.F_jssj);
   subrow.jssj=(jssj.getFullYear()) + "-" + (jssj.getMonth() + 1) + "-" + (jssj.getDate());
   subrow.jhsl=row.F_sl;
   subrow.dj=row.F_dj;
   subrow.jhje=row.F_je;
   subrow.zk=row.F_zk;
   self_.data.sub__wlmtmx.push(subrow);
 }
});
