problem with "onfocus" attribute

Dawie

If I type in "john" in name1 and "smith" in name2 and I click in name3 to give it the focus, I want to see "johnsmith" in name3. Thanks a lot once again!

</form>
</body>
</html>

1) Name your form. Javascript needs to know how to get to the field, which means it needs the form, as well.
2) Use the value attribute of the field to change it:
document.formname.fieldname.value = document.formname.field2name.value;

<html>
<body>
<form method=POST action="test.php">

<table>
<tr><td><input type=submit value="Go"></td></tr>

<tr><td>
<input type=text name="Name1" size="5" maxlength="5">
</td></tr>

<tr><td>
<input type=text name="Name2" size="5" maxlength="5">
</td></tr>

<tr><td>
<input type=text name="Name3" size="10" maxlength="10"
onfocus="?????????" >
</td></tr>
</table>

</form>

In the head secton

In the onFocus attribute of your form
onFocus="document.forms[0].Name3.value = strUnion(document.forms[0].Name1.value,document.forms[0].Name2.value);"

Thanks guys for your answers above. Is there no way that this can be done in PHP in stead of javascript? Sorry, if this is a newbie question... I am one :-)

There is a newbies forum here but I'll answer anyway.

PHP is a sever side language where as javascript is a client side language.

This means that javascript can be fired off to make the web page respond to user actions. Where as php requires that an http request be passed and a new page loaded to create that response.

This means that you could have your on focus submit the form and then spit out the same form again but this time with the fields filed in, however you cannot have php run on the client machine and create interaction with the user.
