Moving options from a <select> to a <select multiple> - the option select attribute is breaking?
by stargazr in Web Design

I'm trying to write a plugin for Prototype where a user clicks on a dropdown and it replaces it with a multi-select element. I am almost finished with it. Everything works great until a user selects what they want displayed, and submits the form to the same page. I am using PHP to keep what the user chose selected using the selected attribute of the <option> tag.

by Sascha Brossmann in Programming Languages

This should be fairly simple but it's tricky to find the right term to use when searching.

In the query below, I need to select WHERE lang='en' ONLY if WHERE lang='nl_NL' returns nothing. In other words, I want to find all records WHERE script='generic', prioritised by lang=nl_NL

Pre-select Select or Mult-Select options from the existing ones instead of adding and selecting a new option
by California in Programming Languages

This code retrieves and displays the customer's account information from the database and pre-selects the values matching their information.

The problem is that instead of selecting from amongst the existing Select or Mult-Select options it is adding and selecting a new option with the relevant value/s. How can I correct it so that it selects from the existing options?

Inner joining to a select statement where the inner select statement's where clause references the outer select?
by Ir0nh1de in Databases

This is a slimmed down query of my greater problem, but the gist is that I'm trying to inner join to a select where the select is limited by the outer select. Is that possible? I'm getting an error about multipart identifier S.Item and S.SerialNum on the inner select.

How to use javascript or jQuery to quickly select a preset of multi-select listbox items?
by docp in Javascript

So say my page has a list of indexes '1,3,4,5,9,12' and a multi-select listbox with 12 items in it.

What's a fast way to use javascript to tell the listbox to multi-select all items at those indexes?

How would this be done using jQuery?

So for example if the user selects the 'caramel' preset associated with the 'candybar' listbox, it will select all the candy
