Hi,
While working with JSP and JAVASCRIPT I came across a unique problem. Let me explain the problem.

Its like I am having a text attribute

input type=text name=myAttribute value=0

and a button like

input type=button name=Submit value=Submit onclic=javascript:myFun()


in the function myFun() in javascript in change the value of attribute myAttribute to 1 as...

document.formName.myAttribute.value=1;

followed by submit() call.

This is working fine a new JSP is opening with the data displayed and a BACK button. The click on the Back button is a call of History.back() that takes me back to the previous JSP page.

Now the problem that I am finding is in the global javascript part I put an alert to find the value of the attribute -- myAttribute --. The value that I am getting in alert is 0 and not 1. But the text box is showing the entry as 1 and not 0.

My Findinds: I found that all the attributes whose value has not been changed using any javascript function is showing the correct value at the same place if I see using alert at the global javaScript part.

Pls suggest where I am making mistake.

Thanks,
Sharan

I would not use history.back at all. By doing so you are opening yourself up to browser-specific beahavior. You will have more control over what occurs if you wire your "back" button to directly address the target page with whatever parameter values are appropriate.
 
It is sorta covered in the JavaRanch Style Guide.
