I had a problem earlier today: I needed to have a select box that returns 2 or more values in stead of 1.
I got this far:
The value of the options gets the id of the item that is displayed in each option.
I do have an other value that should be linked on this option. Is there an easy way to do this?
<select id="category" name="data[cat]">
<option label="0" value="12">A</option>
<option label="0" value="7">B</option>
</select>
I tried to do this with entering the second value into a label attribute but then the problem is that i don’t know the correct way to get the label value of the selected option. This is written in Jquery.
To get the selected option I use:
$("#category").livequery('change', function () {
var catId = ($(this)[0].value);
});
the solution seems to be quite simple:
The label attribute is used by some browsers to display the content of the option, so your list box might display two 0 options.
A better solution might be to do the following:
<select id="category" name="data[cat]">
<option value="12,0">A</option>
<option value="7,0">B</option>
</select>
and split the value in the event handler, e.g.
$("#category").livequery('change', function () {
var values = ($(this)[0].value).split(",");
var catId = values[0];
var otherId = values[1];
});
Wasn’t that easy
Do you have a working sample I could look at? I would appreciate it.

Thank for taking the time with the example. I still seem to be doing something wrong. I pasted my code below. What I’m trying to do is pass multiple values for option test
Your help is appreciated
html
==============================
All
test
Goods
Services
Wants
Your script modified to use weblog_id
===============================
jQuery(function($) {
$(“#weblog_id”).change(function () {
var values = ($(this)[0].value).split(“,”);
console.log(“first value = ” + values[0]);
console.log(“second value = ” + values[3]);
});
});
Why do you use values[3] ?
Below is the form code. Hopefully it shows in the comment. I’m trying to pass values 2,3
”
All
test
Goods
Services
Wants

I Removed the in the code so you get a better Idea.
select id=”weblog_id” name=”data[cat]”
option value=”null” selected=”selected”>All/option
option value=”2,3″test/option
option value=”3″>Goods/option
option value=”2″>Services/option
option value=”5″>Wants/option
/select
Ok, Think I finally got it to work.
