高手接分
页面上两个控件CheckBox1，CheckBoxList1，当我选择CheckBoxList1的项时，CheckBox1的选择状态为非选，当选择CheckBox1时，CheckBoxList1的所有项都选择
马上揭贴！
------解决方案--------------------
<asp:CheckBox onclick= "javascript:GoSelect(this); " ID= "CheckBox1 " runat= "server " /> <asp:CheckBoxList ID= "CheckBoxList1 " runat= "server "> <asp:ListItem Value= "1 "> A </asp:ListItem> <asp:ListItem Value= "2 "> B </asp:ListItem> <asp:ListItem Value= "3 "> C </asp:ListItem> </asp:CheckBoxList> <script type= "text/javascript "> <!-- function GoSelect(obj) { var tb = document.getElementById( "CheckBoxList1 "); for(var i=0;i <tb.rows.length;i++) { tb.rows[i].cells[0].firstChild.checked = obj.checked; } } //--> </script>
------解决方案--------------------
借用cpp2017(慕白兄)的：
<asp:CheckBox onclick= "javascript:GoSelect(this); " ID= "CheckBox1 " runat= "server " />
<asp:CheckBoxList ID= "CheckBoxList1 " runat= "server ">
<asp:ListItem Value= "1 "> A </asp:ListItem>
<asp:ListItem Value= "2 "> B </asp:ListItem>
<asp:ListItem Value= "3 "> C </asp:ListItem>
</asp:CheckBoxList>
<script type= "text/javascript ">
<!--
function GoSelect(obj)
{
var tb = document.getElementById( "CheckBoxList1 ");
for(var i=0;i <tb.rows.length;i++)
{
tb.rows[i].cells[0].firstChild.checked = obj.checked;
}
}
function CheckSelect(obj)
{
var chk=true;
var tb = document.getElementById( "CheckBoxList1 ");
for(var i=0;i <tb.rows.length;i++)
{
if(!tb.rows[i].cells[0].firstChild.checked)
{
chk=false;
}
}
if(chk)document.getElementById( "CheckBox1 ").checked=true;
else document.getElementById( "CheckBox1 ").checked=false;
}
//-->
</script>
cs:
for(int i=0;i <CheckBoxList1.Items.Count;i++){
CheckBoxList1.Items[i].Attributes.Add( "onclick ", "CheckSelect(this) ");
}
