how pass parameter from one jsp to another jsp using button onclick??

i use this one..
onclick="location.href='http://localhost:8080/sampleajax/getpass.jsp"

in the above how can i pass parameter???

in this case, i assume that this is on a different page than the getpass.jsp and we want to on click make it go to to this getpass.jsp.

for an onClick() event handler, this is entirely a client-side javascript operation here. that is to say, this is not JSP specific.

perhaps you could use a HTML <form> with a hidden field(s) that you would stuff full of the parameters you would want to send to the second page. And then, have the onClick() post this form, instead of adjusting the location.href.

For example.

<form name="submitToGetPassForm" action="getpass.jsp">
  <input type="hidden" name="param1" value="someValue"/>
  <input type="hidden" name="param2" value=""/>
</form>

<script type="text/javascript">
  function doGetpass() {
    var form = document.forms['submitToGetPassForm'];
    // stuff some value into the form field
   form.elements['param2'].value='myothervalue';
   form.submit();
 }
</script>
<span onClick="doGetpass();">Bla bla bla</span>

You could also have the option of making this be a POST or GET style request.

Note its been a while since i've had to do JavaScript, so this is probably terrible coding:).

This is how I do my passing,
var Customer Number = 273;

the param CN for Customer Number

onclick="location.href='http://localhost:8080/sampleajax/getpass.jsp?CN=273";

or put it in a variable

onclick="location.href='http://localhost:8080/sampleajax/getpass.jsp?CN="+CustomerNumber+""

than it will get carried to the next page where you will put this function at the top of your page,

function gup( name ){  
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");  
var regexS = "[\\?&]"+name+"=([^&#]*)";  
var regex = new RegExp( regexS ); 
 var results = regex.exec( window.location.href );  
if( results == null )    return "";  
else    return results[1];};

than

var newpageCustomerNumber = gup ( 'CN' );

to get the variable
