Question

I have looked previous questions on this topic on SO, but my problem is not solved yet.

I am passing the array from javascript to servlet.

JavaScript Code:

var action = new Array();
function getProtAcionValues(rowNo,columnCount)
{
    for(var j=0;j<columnCount;j++)
    {
        action[j] =  document.getElementById('textActions'+rowNo+''+j).value;
        alert(action[j]);
    }
}

Servlet Code:

String actions[] = request.getParameterValues("action[]");
if(actions!=null)
for(int i=0;i<actions.length;i++)
{
    System.out.print(" Action: "+actions);
}
else
    System.out.println("Action is null");

Using above code I am getting message “Action is null”.

And if I try

String actions[] = request.getParameterNames("action[]");

I am getting Syntax error:

The method getParameterNames() in the type ServletRequest is not applicable for the arguments (String)

Please let me know if there is something wrong in code.

Answer 1

you can just simply get the array with the name of the array…

String actions[] = request.getParameterValues(“action”);
