Try this

function validate()
{
 var textbox= $("#inputtextbox").val();
 var match = /^([a-zA-Z0-9]{3,})$/;
 if(!match.test(textbox)) {
 $("#dataError").text('Maximum 3 alpha numeric characters and space allowed.');
 $("#dataError").show().fadeOut(5000);

return false;
}
<span id=""></span>

<form onsubmit="return validate()" >
