Question about submitting in a jsp page using (IE and mozilla) 1

FreshmenProgrammer · Feb 23, 2006

This is a simple jsp program below in mozilla when i press submit or close the value("pressed") gets posted on the screen beside either submit value or close value depending on what button was pressed. But in IE i get null values for both. Does anyone have any idea why. Thank you so much in advance. Take care.

Code:

<%
String submit = request.getParameter( "submit" );
String change = request.getParameter( "close" );
%>

submit value: <%= submit%><br />
Close value: <%= change%><br />

<form action = "submittesting.jsp" method = "post">
 			
<input type="image" src="images/submit.bmp" value="pressed"    name="submit">
<input type="image" src="images/close.bmp" value="pressed"   name="close">
			
</form>

Hi,

<input type="image" src="images/submit.bmp" value="pressed" name="submit"> your querystring will hold submit_x=111&submit_y=222 where 111 and 222 are the mousepointer x and y locations at the moment you clicked. You should therefor not check on "submit" variable, but on a different variable.

In I.E. you can not find the submit variable value, one can only see the x and y positions of the mousepointer with type="image"

I would rather use JavaScript as a workaround.

Venu,

Thank you for the post it was really helpful. Looking at that I think i would rather do the javascript thing. Can javascript set a post variable and then submit the form. Like set close to pressed and submit the form right after.

what i'm really trying to do is a question confirmation page if i press the change button go back to the previous page and change the questions and if u press submit go to the next page. So i need to set a variable then post the form.

Hi,

Yes before the page submit you need to set the variable with the value using JavaScript.

Ex:

Code:

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
    <title>My Page</title>
    <script language="javascript">
     function setValue(val){
      document.myForm.buttonValue.value = val;
     }
    </script>
  </head>
  <body>
  <%
    String buttonValue = request.getParameter( "buttonValue" );
    if(buttonValue.equals("next")){
     // go to the next question
    }else if(buttonValue.equals("previous")){
      // go back to previous page
    }
  %>

      Button Pressed Value is: <%= buttonValue%><br />
      

<form action ="" method = "post" name="myForm">
 <input type="hidden" name="buttonValue" value="">            
<input type="image" src="images/submit.bmp" value="pressed" name="submit" onClick="setValue('next')">
<input type="image" src="images/close.bmp" value="pressed" name="close" onClick="setValue('previous')">
            
</form>
  </body>
</html>

Cheers
