copied!<p>As you're already changing the form action URL in the onclick (which is a very poor practice, but that aside), why not just adding the row identifier along as well?</p> <pre><code><input type="submit" name="<%=t %>" value="edit" onclick="this.form.action='df1.jsp?flag=1&act=1&edit=<%=t%>';this.form.submit();" /> <input type="submit" name="<%=t %>" value="delete" onclick="this.form.action='df1.jsp?flag=1&act=1&delete=<%=t%>';this.form.submit();" /> </code></pre> <p>This way you can just do:</p> <pre><code>String edit = request.getParameter("edit"); if (edit != null) { // Edit button of row "edit" was invoked. Do your job here. } String delete = request.getParameter("delete"); if (delete != null) { // Delete button of row "delete" was invoked. Do your job here. } </code></pre> <p>Otherwise you'd need to prefix the button name with some fixed identifier:</p> <pre><code><input type="submit" name="edit_<%=t %>" value="edit" onclick="this.form.action='df1.jsp?flag=1&act=1';this.form.submit();" /> <input type="submit" name="delete_<%=t %>" value="delete" onclick="this.form.action='df1.jsp?flag=1&act=1';this.form.submit();" /> </code></pre> <p>So that you can just do:</p> <pre><code>for (int t = 1; t < 10; t++) { if (request.getParameter("edit_" + t) != null) { // Edit button on index "t" was invoked. Do your job here. break; } if (request.getParameter("delete_" + t) != null) { // Delete button on index "t" was invoked. Do your job here. break; } } </code></pre> <hr> <p><strong>Unrelated</strong> to the concrete problem, writing JSPs this way with <em>scriptlets</em> <code><% %></code> is since a decade considered oldschool and a poor practice.
