hola a todos es que tengo esto

Código HTML:

Ver original<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Documento sin t&iacute;tulo</title>
<script>
var checkobj
 
function agreesubmit(el){
checkobj=el
if (document.all||document.getElementById){
for (i=0;i<checkobj.form.length;i++){  //hunt down submit button
var tempobj=checkobj.form.elements[i]
if(tempobj.type.toLowerCase()=="submit")
tempobj.disabled=!checkobj.checked
}
}
}
 
function defaultagree(el){
if (!document.all&&!document.getElementById){
if (window.checkobj&&checkobj.checked)
return true
else{
alert("Please read/accept terms to submit form")
return false
}
}
}
 
</script>
</head>
 
<body>
<form name="form" onSubmit="return defaultagree(this)">
Rest of your form here<br>
<input name="check" type="checkbox" onClick="agreesubmit(this)"><b>I agree to the above terms</b><br>
<input type="text" name="user" value="" size="25">
<input type="text" name="pass" value="" size="25">
<input type="Submit" value="Submit!" disabled>
</form>
 
<script>
//change two names below to your form's names
document.forms.form.check.checked=false
document.forms.form.user.checked=false
document.forms.form.pass.checked=false
</script>
</body>
</html>
