ecology9.0 主表浏览框控制明细表必填，只读并赋值与清空

需求： 通过采购子类这个浏览按钮改变明细表一的IT细类，类别字段属性及字段值

当采购子类为终端类时，通过点击事件将终端类赋值给IT明细，并且类别为必填

 核心JS代码： 时间不够导致代码没有抽取，有冗余。

<script type="text/javascript">
jQuery(document).ready(function() { 
WfForm.bindFieldAction("onclick", "field20010", function(){ // var xm=WfForm.getBrowserShowName("field20010");//项目var xm =   $("#field20010").val();if(xm=="22"){		//终端类	var rowArr = WfForm.getDetailAllRowIndexStr("detail_1").split(","); //遍历明细表一for(var i=0; i<rowArr.length; i++){var rowIndex = rowArr[i];if(rowIndex !="undefined" ){		var fieldMark = "field20301_"+rowIndex;    //遍历明细行 WfForm.changeSingleField(fieldMark, {value:"0"}, {viewAttr:"1"}); var hh = parseInt(rowIndex);  //将字符串的数字转成int类型数字for(var j=hh; j<rowArr.length; j++){WfForm.changeFieldAttr("field20300_"+j, 3);//必填}}}		}else if(xm=="23"){		//非终端类	var rowArr = WfForm.getDetailAllRowIndexStr("detail_1").split(","); //遍历明细表一for(var i=0; i<rowArr.length; i++){var rowIndex = rowArr[i];if(rowIndex !="undefined" ){		var fieldMark = "field20301_"+rowIndex;    //遍历明细行 WfForm.changeSingleField(fieldMark, {value:"1"}, {viewAttr:"1"}); var hh = parseInt(rowIndex);  //将字符串的数字转成int类型数字for(var j=hh; j<rowArr.length; j++){WfForm.changeFieldAttr("field20300_"+j, 3);	  //必填 		 }}}		}else{		//其他var rowArr = WfForm.getDetailAllRowIndexStr("detail_1").split(","); //遍历明细表一for(var i=0; i<rowArr.length; i++){var rowIndex = rowArr[i];if(rowIndex !="undefined" ){		var fieldMark = "field20301_"+rowIndex;    //遍历明细行 	  WfForm.changeFieldAttr(fieldMark, 1);//只读WfForm.changeSingleField(fieldMark, {value:""}, {viewAttr:"1"}); var hh = parseInt(rowIndex);  //将字符串的数字转成int类型数字for(var j=hh; j<rowArr.length; j++){WfForm.changeFieldAttr("field20300_"+j, 1);	//只读					}}}		}     
});
