I'm new to javascript, so I figure som of you guys in here can answer my question pretty easily:
I have this code which works:
[HTML]<script type="text/javascript">
</script>
</head>
<body>
<table>
<tr>
<th style="text-align: center;"> Adresse </th>
<th style="text-align: center;"> Salgspris </th>
<th style="text-align: center;"> Beboelsesareal </th>
</tr>
<tr>
<td> Klostergade 2 3. sal - 8000 Aarhus C </td>
<td> 2.495.000 kr </td>
<td> 119 kvadratmeter </td>
</tr>
<tr>
<td> Volden 12 3. sal - 8000 Aarhus C </td>
<td> 2.698.000 kr </td>
<td> 97 kvadratmeter </td>
</tr>
<tr>
<td> Vester Alle 27 2. sal tv - 8000 Aarhus C </td>
<td> 2.795.000 kr </td>
<td> 92 kvadratmeter </td>
</tr>
</table>
<form action="#" name="udregn">
<p> Indtast prisen <input id="pris" type="text" name="pris"> </p>
<p> Indtast areal <input id="areal" type="text" name="areal"> </p>
<p> <input id="meterpris" type="text" name="meterpris " disabled> kr pr. kvadratmeter </p>
<p> <input id="udregn" type="button" value="Beregn kvadratmeterpri sen"
onClick="docume nt.udregn.meter pris.value = document.udregn .pris.value / document.udregn .areal.value"> </p>
</form>
</body>
</html>
[/HTML]
But I want to separate my javascript from my html and I tried som different things like this:
[html]<script type="text/javascript">
window.onload = function ()
{
document.getEle mentById("udreg n").onClick =
function()
{
document.getEle mentById("pris" ).value / document.getEle mentById("areal ").value
}
}
</script>
</head>
<body>
<table>
<tr>
<th style="text-align: center;"> Adresse </th>
<th style="text-align: center;"> Salgspris </th>
<th style="text-align: center;"> Beboelsesareal </th>
</tr>
<tr>
<td> Klostergade 2 3. sal - 8000 Aarhus C </td>
<td> 2.495.000 kr </td>
<td> 119 kvadratmeter </td>
</tr>
<tr>
<td> Volden 12 3. sal - 8000 Aarhus C </td>
<td> 2.698.000 kr </td>
<td> 97 kvadratmeter </td>
</tr>
<tr>
<td> Vester Alle 27 2. sal tv - 8000 Aarhus C </td>
<td> 2.795.000 kr </td>
<td> 92 kvadratmeter </td>
</tr>
</table>
<form action="#" name="udregn">
<p> Indtast prisen <input id="pris" type="text" name="pris"> </p>
<p> Indtast areal <input id="areal" type="text" name="areal"> </p>
<p> <input id="meterpris" type="text" name="meterpris " disabled> kr pr. kvadratmeter </p>
<p> <input id="udregn" type="button" value="Beregn kvadratmeterpri sen"> </p>
</form>
</body>
</html>[/html]
It doesnt seem to work though - can I get som help?
