Sometimes you would like a delay between the presentation of the decision situation and the possibility to make a choice. This can be easily done in javascript. The relevant buttons are only displayed some seconds after the page is loaded. In the body statement you refer to a javascript function opdracht(). The javascript opdracht() waits 5000 milliseconds before referring to another function vulin() who than fills in the field with id 1 the html code for the submit button.
<body onload="opdracht()" text=#000000>
<SCRIPT LANGUAGE="JavaScript">
function opdracht()
{setTimeout("vulin()",5000);
}
function vulin() {
document.getElementById("1").innerHTML = "<input type=\"submit\" name=\"verzend\" id=\"button\" value=\"verzend\" />";
}
</SCRIPT>
<form>
//Here other elements of the form like inputs or radio buttons, submit button appears after delay
<p align=center>
<div align=center id="1"></div>
</p>
</form>
