So when someone types 30,4 it changes to 30.4 automatically.</p> <p>This is the javascript:</p> <p>&lt;script type="text/javascript"&gt;<br /> function commadot(that) {<br /> if (that.value.indexOf(",") &gt;= 0) {<br /> that.value = that.value.replace(/\,/g,".");<br /> }<br /> }<br /> &lt;/script&gt;</p> <p>Where can I place this script?</p> <p>To the formfield itself I guess I have to add something like: onkeyup="commadot(this)</p> <p>Where to add this? </p>
