1、获取单个字段值

//获取主表值
var fieldvalue = WfForm.getFieldValue("field110");
//获取明细表：字段_+行号（从0开始算）
var field19112Value = WfForm.getFieldValue("field19112_"+rowIndex);

2、修改单个字段值

//主表：修改文本框、多行文本、选择框等字段类型
WfForm.changeFieldValue("field123", {value:"1.234"});
//明细表：字段_行号
WfForm.changeFieldValue("field19113_"+rowIndex, {value:"值"});
//延时修改值
window.setTimeout(function(){
    WfForm.changeFieldValue("field19637_"+rowMax, {value:newVal});
}, 100);

3、明细字段值变化触发事件：支持删除行时也触发

//可多个拼接逗号隔开，例如：field110,field111
//参数1：字段标示(field27583)，参数2：行标示，参数3：修改后的值
<script>
    jQuery(document).ready(function(){ 
    WfForm.bindDetailFieldChangeEvent("field19112",function(id,rowIndex,value){
        var rowArr = WfForm.getDetailAllRowIndexStr("detail_3").split(",");
        var map = {};
        for(var i = 0; i < rowArr.length; i++){
          var rowNumber = rowArr[i];
          var field19112Value = WfForm.getFieldValue("field19112_"+rowNumber);
          if(map.hasOwnProperty(field19112Value)){
            map[field19112Value] = ++map[field19112Value];
          }else{
            map[field19112Value] = 1;
          }
          var val = map[field19112Value];
          WfForm.changeFieldValue("field19113_"+rowNumber, {value:val});
        }       
    });     
});
</script>

4、T100项次等于行号：新增删除行时行号自动赋值给项次（行号从0开始，项次从1开始）

<script>
    jQuery(document).ready(function(){
      WfForm.changeFieldValue("field19110_" + 0, {value: 1});
      WfForm.registerAction(WfForm.ACTION_ADDROW+"1", function(index){
          let key = WfForm.getDetailRowSerailNum("detail_1", index);
          //修改文本框、多行文本、选择框等字段类型
          WfForm.changeFieldValue("field19110_" + index, {value: key});
      }); 
      WfForm.registerAction(WfForm.ACTION_DELROW+"1", function(arg){
        var rowArr = WfForm.getDetailAllRowIndexStr("detail_1").split(",");
        for(var i=0; i<rowArr.length; i++){
            var rowNumber = rowArr[i];
            if(rowNumber !== ""){
                let key = WfForm.getDetailRowSerailNum("detail_1", rowNumber);
                WfForm.changeFieldValue("field19110_" + rowNumber, {value: key});
            }
        }
      });     
});
</script>
