泛微OA【e-cology.9】JS生成方案编号且始终按顺序排列

<script type="text/javascript">
/*
field20118 方案编号字段ID
*/
function addFanganNo(){
	var subIndex = $('#submitdtlid0').val();
	var arr = subIndex.split(",");
	var len = arr.length-1;
	for(var i=0; i<len; i++){
		var codeNo = '';
		if(i < 9){
			codeNo = '0' + (i + 1);
		}else{
			codeNo = i + 1;
		}
		WfForm.changeFieldValue("field20118_" + arr[i], {value:"方案 " + codeNo});
	}
}
function _customAddFun0(){
	addFanganNo();
}		
function _customDelFun0(){
	addFanganNo();
}

</script>

不管序号如何删减，始终按照顺序排列。
