Combining two functions

Luis · Aug 31, 2004

Is there a way to combine the following ShowName()
functions so that I can just call one function on the onblur event of
the text field?

<html>
<head>
<script language="JavaScript">
function ShowName1() {
alert "You were on Field1"
}

function ShowName2() {
alert "You were on Field1"
}
</script>
</head>

<body>
<input type="text" name="Field1" onblur="ShowName1()">
<input type="text" name="Field2" onblur="ShowName2()">
</body>
</html>

My first thought is to establish which field had the focus and then pass
that field name to the function. But how do I determine which field had
the focus?

The easiest way is probably to use the "this" keyword:

<html>
<head>
<script type="text/javascript">
function ShowName(n) {
alert ("You were on "+n.name);
}
</script>
</head>

<body>
<input type="text" name="Field1" onblur="ShowName(this)">
<input type="text" name="Field2" onblur="ShowName(this)">
</body>
</html>

Hi,

simply pass an argument to your function.

....onblur="ShowName1("1")"> // make sure, the "" are correct!!

in the function you use:

function ShowName1(x) {
// of course you can use a switch - case statement and/or some if's to
get the appropriate actions
alert ("you've been in field " +x);
}

HTH,

Andy

You want those to be single quotes ('):

...onblur="ShowName1('1')">

or entity references:

...onblur="ShowName1("1&quot

">
