在一个表单中有几个素面输入文本控件和命令按钮。在一个输入文本上按回车键需要激活相关命令按钮的点击。如何实现该功能?我试着使用onkeydown，但是找不到方法
你可以尝试(你需要自己找到在javascript中检测输入键)
xhtml:<p:input onkeydown="test()" />
<p:commandButton styleClass="foo" />
function test(){
$('.foo').click();
}

在RongNK的指导下，我将代码修改如下，它完美地达到了我的目的。
添加CDATA以包含JavaScript。使用\转义JSF组件id中的:
<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;
}
}
// ]]>
</script>
