birt一点一滴系列之根据选择的指标实现不同统计图表切换

1、在grid中得合适位置添加 切换指标元素控件。如：html中得列表列表控件

<script type="text/javascript">
function funSelectIndex() {
	var tar = new String(document.getElementById("selectIndex").value);
	var temp = new String(location.href);
	var targetURL = new String();
	if(temp.indexOf("&startTime=") != -1 ){
		targetURL = temp.substring(0, temp.indexOf("&startTime"));
	}else{
		targetURL = temp;
	}
	targetURL += "&startTime=<VALUE-OF>params["startTime"].value</VALUE-OF>";
    targetURL += "&endTime=<VALUE-OF>params["endTime"].value</VALUE-OF>";
	targetURL += "&paraDep=<VALUE-OF>params["paraDep"].value</VALUE-OF>";
	targetURL += "&paraTermp=<VALUE-OF>params["paraTerm"].value</VALUE-OF>";
	targetURL += "&dealerName=<VALUE-OF>params["dealerName"].value</VALUE-OF>";
	targetURL += "&pSelectIndex=" + tar;
	alert(targetURL);
	location.replace(targetURL);	
}

</script>

<select id="selectIndex" onchange="funSelectIndex()">
<option value="amount" <VALUE-OF>if(params["pSelectIndex"].value=="amount"){selectted="selected"}</VALUE-OF>>实付金额</option>
<option value="cost" <VALUE-OF>if(params["pSelectIndex"].value=="cost"){selectted="selected"}</VALUE-OF>>实收金额</option>
<option value="orderNum" <VALUE-OF>if(params["pSelectIndex"].value=="orderNum"){selectted="selected"}</VALUE-OF>>订单数量</option>
<option value="price" <VALUE-OF>if(params["pSelectIndex"].value=="price"){selectted="selected"}</VALUE-OF>>课单价</option>
<option value="perforpercent" <VALUE-OF>if(params["pSelectIndex"].value=="perforpercent"){selectted="selected"}</VALUE-OF>>成单率</option>
</select>

2、 设置器效果

3、在报表参数中定义选择参数项。如：selectIndex

4、点击饼图 在“扇面大小”中添加判断js脚本

if(params["pSelectIndex"].value=="amount")
{	
	row["paidamount"]
}else if(params["pSelectIndex"].value=="cost")
{	
	row["costamount"]
}else if(params["pSelectIndex"].value=="orderNum")
{	
	row["ordersNum"]
}else if(params["pSelectIndex"].value=="price")
{
	row["ordersNum"]
}else
{
	row["perforpercent"]
}

 目的是根据pSelectIndex选择的数值实现对 统计指标的切换

5、运行效果
