I'm using the common javascript alert in a field-checking function:
if(document.cadFinan.dataParcel.value == ""){
alert("O Campo data é obrigatório!");
return false;
}
But I'd like something nicer, some custom text box to display the message.
You could use jQuery with some plugin, for example I'm using the jquery.modal.js: plugin, but there are many plugins available on the internet, and only search for jquery plugin model.
<!DOCTYPE html>
<html>
<head>
</style>
<script src="jquery.js" type="text/javascript" charset="utf-8"></script>
<script src="jquery.modal.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="ex1" style="display:none;">
<p>Thanks for clicking. That felt good. <a href="#" rel="modal:close">Close</a> or press ESC</p>
</div>
<p><a href="#ex1" rel="modal:open">Open Modal</a></p>
</body>
</html>
This example I took from the plugin's own website: link
