如何在joomla中进行javascript验证？

Answer 1

使用JHTML::_('behavior.formvalidation');

与前端相同

这是Joomla's tuturial for adding validation。唯一的区别是您必须复制invalid类的CSS，它会在值无效时突出显示文本框。

另外，我个人的偏好。而不是编码<form ... onsubmit="return jsFunction()">我喜欢这样做：

<script type="text/javascript">

window.addEvent('domready', function(){

// Add submit event to the form
$('myForm').addEvent('submit', function(e){
    // Default check
    var isValid = document.formvalidator.isValid(frm);

    // Do additional checks + create message
    var msg  = '';
    if (!isValid){
        msg = 'Some values are not acceptable. Please retry.';
    }else if($('some-other-value').value == 0){
        msg = 'Select IO';
        isValid = false;
    }

    if (!isValid){
        // Stop event
        new Event(e).stop();

        // Somekind of invalid form handler... can do effects in here, etc...
        handleInvalidForm(this, e, msg);
    }

    //
    return isValid;
});


});

</script>
