回答“QQ1145306946”提的问题“jsp 勾选数据添加到另一个页面”

解答http://www.iteye.com/problems/95288#s_200578的问题
以下是之前做过的，直接搬过来给你，你看看能不能去里面借鉴一下。下面的文件命名也是之前原班的
注意修改点：
1.本例中的“选择”按钮等同于你表单中的“增加”按钮
2.本例中在弹出页面勾选好了，点击“确定”按钮后，只将品名带出来了，而你的需求应该是把所有的都带出来吧，所以如果你想将其他字段的值也带出来你就在purchase.js中添加
3.本例不是很全，有可能不太看得懂，可以结合之前跟你说的图片看

1.PurchaseEdit.jsp（表单主页面）
注意：此处需要将purchase.js导入，并设置一个隐藏域selectgoods来接收你到时候所选物品id(第一二行)

此处把点击“确定”时的js代码复制出来

function updateData() {
               //此处三行代码表示获取已勾选的数据的id，再将id赋给selectgoods，也就是刚才页面的隐藏域的那个，此处你自己需改    
		var deleteFlags="deleteFlag";
		var childFrame=document.getElementById('List').contentWindow;
	    var checkBoxList = childFrame.document.getElementsByName(deleteFlags);  
	    var checkIds="";  
	    for (var i=0;i<checkBoxList.length;i++){
	        if (checkBoxList[i].checked){
	            if(i==0)
	            {
	            	checkIds = checkBoxList[i].value + ",";
	            }
	            else
	            {
	            	checkIds = checkIds + "," + checkBoxList[i].value;
	            }
	            
	        }
	    } 
		var ParentForm = window.dialogArguments.document.getElementById("selectgoods");
		//alert(checkIds);
		ParentForm.value=checkIds;
        window.returnValue=1;
        onReturn();

请问最后的代码function updateData() {是放在PuerchaseGoodsSelect.jsp里吗？

对，就是里面的点击“确定”时的function

请问，这样的功能是否用购物车的方法来做呢？

不是，就是普通的js实现
