onkeydown event triggering clicking a command button

Question

There are several primefaces inputtext controls and commandbuttons in a single form. Pressing the return ket on one inputtext need to activate the click of related commandbutton. How can I achieve that functionality? I tried to use onkeydown even, but could not find out the method.

Answer 1

As guided by RongNK, I changed my code as below and it serves my purpose perfectly.

Added CDATA to include JavaScript. Used \\ to escape : in id of JSF compoents

  <h:form id="frmEn">
                <script type="text/javascript" language="JavaScript">
                    //<![CDATA[    
                    function forDx(e) {
                        if (e.keyCode === 13) {
                            $('#frmEn\\:btnDx').click();
                            return false;
                        } else {
                            return true;
                        }
                    }
                    function forIx(e) {
                        if (e.keyCode === 13) {
                            $('#frmEn\\:btnIx').click();
                            return false;
                        } else {
                            return true;
                        }
                    }
                    function forMx(e) {
                        if (e.keyCode === 13) {
                            $('#frmEn\\:btnMx').click();
                            return false;
                        } else {
                            return true;
                        }
                    }
                    function forRx(e) {
                        if (e.keyCode === 13) {
                            $('#frmEn\\:btnRx').click();
                            return false;
                        } else {
                            return true;

Answer 2

You can try(you need to find to detect enter key in javascript by yourself)

xhtml:

<p:input onkeydown="test()" />
<p:commandButton styleClass="foo" />

javascript:

function test(){
$('.foo').click();
}
