Thanks

hi
I wrote a sample code for you.
[HTML]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Untitl ed Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<script language="javas cript">
<!--
function check()
{
var check1 = document.getEle mentById("check 1");
var check2 = document.getEle mentById("check 2");
if (check1.checked && check2.checked )
alert ("You should check only 1.");
}
-->
</script>
<input type="checkbox" id="check1" />Check1
<br />
<input type="checkbox" id="check2" />Check2
<br />
<input type="button" value="test" onclick="check( );"/>
</body>
</html>
[/HTML]
and another suggestion for you:
you can use radio box to satisfy your requirement without javascript.here is another sample code for you.
[HTML]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Untitl ed Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<input type="radio" id="check1" name="check" />Check1
<br />
<input type="radio" id="check2" name="check" />Check2
</body>
</html>
[/HTML]
attention: you should give these 2 radio box a same name,and then,they can work together.
hope it helps.
Thanks a lot for your reply
My requirement is, i have check boxes in my PDF file and i dont want the user to check both the boxes. The idea of Radio button would definitely work, but i do not have the access to change that.
I am trying to run the JavaScript in the PDF file. The way to add the script in the PDF file is
1) Right Click on the check box and then Properties and then click on the Actions Tab and then "Select Action"--> "Run a JavaScript"
Unfortunately your script is not working, it might be for an HTML page. Do you have any other ideas
Thanks
Jack
hi
i'm sorry i have no idea about the javascript in PDF,but I guess it makes no difference.
my code : -
var check1 = document.getElementById("check1");
-
var check2 = document.getElementById("check2");
-
can work,i guess.But you couldn't copy it directly.you should change the parameter in getElementById. The parameter is the id of the check box in your PDF file. if you can find the id,you will get the right script.
hope it helps.

I have a PHP generated page which displays X many records. Each record has
a checkbox preceding it. The user checks several checkboxes, and hits a
delete button. All the corresponding records will be deleted.
But I'm running into difficulty...
Right now the NAME property of each check box is the primary key of the
corresponding record. Hence if I know which checkboxes are checked, I
simply use DELETE using the NAME value.

Hi all..
I have a DataGrid with checkboxes. In the header I have a "check all"
checkbox.
I'm wondering if there is an easy way to check all checkboxes using that
checkbox. I could do it using JavaScript code, but the main problem I have
is that checkboxes ids aren't kept when the datagrid is rendered, for
example, if the checkboxes have the name chkNumid, when the datagrid is
rendered, the checkboxes become dgDataGrid_ctl02_chkNumId,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
