Stuck in the 80s
Code:
<html>
<head>
<script language ="javascript">
function Change()
{
document.test1.tbText1.value = 20
return false;
}
</script>
<body>
<form name="test1" method="post" onsubmit ="return Change()">
<input type="text" name="tbText1">
<br>
<input type="submit" value="submit">
</form>
The reason why you can't see the value is because the form is submitting (in this case, reloading the page).
Another method for this would be:
Code:
<html>
<head>
<script language ="javascript">
function Change()
{
document.test1.tbText1.value = 20
}
</script>
<body>
<form name="test1" method="post">
<input type="text" name="tbText1">
<br>
<input type="button" value="submit" onclick="Change()">
</form>
