dhtmlxGrid 如何查出改的是列表的哪一个字段下的值

[ttyyaabb]

代码如下我想知道被改动的项的主键是哪个，被改动项是cellValue的值，主键在表单的第一列

function f_batchSave()
{
	
	var allitemid = new Array(0);       
	var modiitemid = new Array(0);       
	allitemid = mygrid.getAllItemIds().split(","); 
	   
	var cc = mygrid.getColumnCount();    
	var colLabel=mygrid.getColumnLabel(1);
	alert(colLabel);
	var saveflag = false;       
	var blankflag = false;       
	var a = 0;       
	for (var i = 0; i < allitemid.length; i++) {       
	var modiflag = false;       

		for (var j = 0; j < cc; j++) {     
		var cellValue = mygrid.cells(allitemid[i], j).getValue();   
			if (mygrid.cells(allitemid[i], j).wasChanged()) {   
				modiflag = true;
				alert(cellValue); 
				
			}       
  		
			if (cellValue == "" || cellValue.length == 0 || cellValue == null) {       
				blankflag = true;       
			}       
		}       
		if (modiflag && !blankflag) {       
			modiitemid[a++] = allitemid[i];       
		}   
	}    	
}

if (mygrid.cells(allitemid[i], j).wasChanged()) {
modiflag = true;
alert(cellValue);


var KeyValue = mygrid.cells(allitemid[i], 0).getValue(); ‘这就是主键
}
