java - Is it possible to assign javascript value to html and use Jsp to get the value? - 


<html> <body>  <form action="javascript.jsp">    <script type="text/javascript">    var = 11;    var j = 12;    <input type="hidden" name="test[0]" value=i />    <input type="hidden" name="test[1]" value=j />    </script>    <input type="image" src="submit.jpg" /> </form>     </body> </html>

i value javascript variable

and assign value @ array, <input type="hidden" name="test[0]" value=i />

then, in server side,

<%! string[] getvalue; %> <%        getvalue = request.getparametervalues("test");        if (getvalue != null)         {           (int = 0; < getvalue.length; i++)            {              out.println ("<b>"+getvalue[i]+"<b>");           }        } %>

but seems not work.

so, possible assign javascript value html , use jsp value?

or how modify code?

use getelementbyid method in javascript locate elements id. , set value property. make sure code executed after page has been loaded.

example:

<html> <body> <form action="javascript.jsp">    <input type="hidden" id="test0" />    <input type="hidden" id="test1" />    <script type="text/javascript">        var = 11;        var j = 12;         window.onload = function()        {            document.getelementbyid("test0").value = i;            document.getelementbyid("test1").value = j;        };    </script>    <input type="image" src="submit.jpg" /> </form>    </body> </html>
