什么是错在这code它仍然给了MSGBOX如果用户选择或不选择复选框? [英] Whats wrong in this code it still gives the msgbox if user select or not select the checkbox?
问题描述
它仍然给了MsgBox,如果我选择复选框BOX OR NOT ....
下面我的code会重定向到谷歌在这两个条件:如果用户选择的复选框,然后它会重定向到www.google.com,但如果用户忘记选中该复选框,然后它显示了味精盒有一个确定按钮。当我点击确定它应该重定向到www.google.com
我想
当用户忘记检查任何复选框来展示使用了MsgBox与OK键并保持在同一页上。否则,如果用户选择任何复选框,然后重定向到www.google.com

对于(I = 0; I&下; = 1;我++){
// chkSubjectOfInterest是你的CheckBox控件的ID 如果(frm.elements [I] .name.indexOf('chkSubjectOfInterest')!= - 1)

如果(frm.elements [I] .checked)
{
返回true
}
}
}
警报('您还没有选择的项目呢!)
返回false

这一点吗?
为(i = 0; I {
应该是这样
为(i = 0; I< = loopnumber;我++)
{}
IT STILL GIVES A MSGBOX IF I SELECT THE CHECKBOX BOX OR NOT ....
My code below will redirect to Google in both conditions: If the user selects the checkbox, then it will redirect to www.google.com, but if a user forgets to check the checkbox then it shows the msg box with an ok button. When I click on ok it should redirect to www.google.com
I want
When a user forgets to check any of the checkboxes to show a msgbox with an ok button and stay on the same page. Otherwise if user selects any of the checkboxes then redirect to www.google.com

<form id="form1" runat="server">
<div>
<asp:CheckBox ID="CheckBox1" runat="server" />
<asp:CheckBox ID="CheckBox2" runat="server" />
</div>
<asp:Button ID="Button1" runat="server" OnClientClick ="return ConfirmSelection(this.form);" Text="Button" />
</form>
<script type="text/javascript">
function ConfirmSelection(frm)
{
for (i=0; i<=1; i++) {
//chkSubjectOfInterest is the id of your checkbox control
if (frm.elements[i].name.indexOf('chkSubjectOfInterest') !=-1)
{
if (frm.elements[i].checked)
{
return true
}
}
}
alert('You havent selected an Item yet!')
return false
}
</script>
</body>
</html>
this bit?
for (i=0; i {
Should be something like
for (i=0; i <= loopnumber; i++)
{
}
