可重用的二级级联JS(一)

function Array2SelectList(srcObj,DefalutSelect,SourceArray,ParentValue)
{
	var OptCount=0;
	var isSelected =false;
	SelectClear(srcObj);//Cleaer Options
	//srcObj.disabled = true;
	//alert(SourceArray.length );
	for(var i = 0;i < SourceArray.length;i++){
		if (SourceArray[i][2] == ParentValue || ParentValue ==null ){
		//alert(SourceArray[i][2] + "-" + ParentValue );
		OptCount++
			//var opt=new Option();
			//opt.value=SourceArray[i][0];
			//opt.text =SourceArray[i][1];
			srcObj.options[srcObj.length]=new Option(SourceArray[i][1],SourceArray[i][0]);
			
			if (SourceArray[i][0] == DefalutSelect){			
				isSelected = true;
				srcObj.options[srcObj.length-1].selected = true;
			}
		}
	}
	
	if (OptCount > 0){;
		srcObj.options[0].text='';
		if (isSelected!=true){srcObj.options[0].selected = true;}
		//srcObj.disabled = false;
	}
	else{
		srcObj.options[0].text='';
	}
	
}

该JS引用后续跟进。
