JQuery Question

Was wondering if someone could help me with the following. I am using the below code to copy the value of a select (bandName) to a form field (keywords) and it works fine. However I was hoping to also append the data from a different select (vID) to end but it over writes whats there. Is there as way to append as opposed to over writing?

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text();
$('#keywords').val(x);
});
});

$(function() {
$('#vID').change(function() {
var x = $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
</script>

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() + $("#vID").find('option:selected').text();
$('#keywords').val(x);
});
});

$(function() {
$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
</script>

Works great. One minor issue. When the vID is appended it doesn't leave a space between words, it combines the last and first words. How do I add the space?

You can add the space in the code:

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() +" "+ $("#vID").find('option:selected').text();
$('#keywords').val(x);
});
});

$(function() {
$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
</script>

How can I do the same for a text field?

just use:

$("#textfieldID").val()

instead of:

$("#selectFieldID").find('option:selected').text()

Yeah I'm not sure I got any of this right:

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() +" "+ $("#vID").find('option:selected').text();
$('#keywords').val(x);
});
});

$(function() {
$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
$(function() {
$("#specialGuest").val(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});

</script>

I'm not exactly sure what you are trying to do, but I think it is probably closer to:

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() +" "+ $("#vID").find('option:selected').text() + " " + $('#specialGuest').val();
$('#keywords').val(x);
});

$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text() + " " + $('#specialGuest').val();
$('#keywords').val(x);
});

$("#specialGuest").blur(function() {
var x = $("#bandName").find('option:selected').text() + " " + $("#vID").find('option:selected').text() + " " + $('#specialGuest').val();
$('#keywords').val(x);
});
});

</script>



Maybe tell me what you are trying to do in plain English so I can understand what the code should be doing. I see you are trying to do something with the specialGuest text field, but I can't tell what you want it happen when the value changes.

I did explain it above but will again here.
The above ones work, the ones you provided.

<script type='text/javascript'>
$(function() {
$('#bandName').change(function() {
var x = $(this).find('option:selected').text() +" "+ $("#vID").find('option:selected').text();
$('#keywords').val(x);
});
});

$(function() {
$('#vID').change(function() {
var x = $("#bandName").find('option:selected').text() + " " + $(this).find('option:selected').text();
$('#keywords').val(x);
});
});
</script>


But now I have a field called specialGuest, it's just a text field and I want the value of that field to also populate into the keywords field after it's typed in.

The only details above were:

"How can I do the same for a text field?"

Which was a bit light on specific details.... I've updated the code example above to do what you describe.
