如果你希望知道当前选中的是哪些节点，其实可以换个思路，
首先在页面上方一个<INPUT id="Text1" type="hidden" name="Text1" runat="server" value=",">
然后改写一下 searchArea ：
function searchArea(objTreeCheckBox)
{
var curID = objTreeCheckBox.value;
var selected = document.getElementById("Text1").value;
if(objTreeCheckBox.checked)
selected += curID + ",";
else
selected = selected.replace(","+curID+",",",");
document.getElementById("Text1").value = selected;
}
那么，无论是在javascript还是在后台C#代码中都可以随时获取目前选中的节点的value值 |
