Can someone help me writing a script that will check if text field contain name and family name and verify that there is space (at least 1 empty space) between the names.

Html:
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
Input Name and Family name:
<input name=&quot;input&quot; type=&quot;text&quot; id=&quot;input&quot;>
</body>
</html>

When you same name and family name, is there a specific list of acceptable names? Or will any characters be acceptable? Is there a minimum number of characters for each set? Get the Best Answers! faq333-2924

OK, good question. The page POST to a PHP script after it and I do not want characters like /[~`!Ҥ@#$%^&*()_+=:;'{}\. And how do I check that there are only two words separated by space or couples of space.

<script>
function alphaOnly(inString){
var illChar = /[~`!@#$%^&*()_+=0123456789:;&quot;'{}\[\]]/gi;

if (inString.search(illChar) != -1){
return false;
}
return true;
}

function twoNames(inField){
nameArr = inField.value.split(/\S+/) //split on one or more spaces
if(nameArr.length != 1){
boolGood = false
}
else{
boolGood = alphaOnly(inField.value)
}
if (!boolGood){
alert (&quot;Please enter a valid name!&quot;)
inField.focus()
}
}
</script>
