Form field check and reflect.

Copy linkTweet thisAlerts:
May 18.2006

I’m new to js, any help appreciated.

I have a form with many numeric fields and its possible value ranges. I need to make a check of the inputted field and reflect by an image at the field if the value is out of its range.

I think to call a function onclick (or there is a better even available?) with value, and range limits, then it checks and shows a little image of that. But! How output the images at the given place at the field, probably every time a user presses the next button?

@s-strongauthorMay 19.2006 — That's what I do:

[CODE]<html>
<head>
<title></title>
</head>
<body>

<form name="c" method="post">
<table>
<tr>
<td>A</td>
<td align=left><input type="text" name="a" id="a" OnMouseOut="check('a1', 'a2', 'a', 10, 20)"></td>
<td id=a1 style="display:none">Low</td><td id=a2 style="display:none">High</td>
</tr>
<tr>
<td>B</td>
<td align=left><input type="text" name="b" id="b" OnMouseOut="check('b1', 'b2', 'b', 1, 2)"></td>
<td id=b2 style="display:none">Low</td><td id=b2 style="display:none">High</td>
</tr>
</table>

<script language="JavaScript" type="text/javascript">
function check(what, again, name, one, two) {
if(name && name != one && name != two){
if (name<one){
what.style.display = ''
again.style.display= 'none'
}
else{
what.style.display = 'none'
again.style.display = ''
}
}
}else{
what.style.display = 'none';
}
</script>
</form>

</body>
</html>[/CODE]

Here, I just want to make a writting of the check result: Low or High.

All the necessary params I do transfer to the function (which field to display, what are the limits of the range, current value), but as it does not work, please correct me in javascript syntax/logic.

Success!
