    <p>I have inherited some code that sets the css of a select box depending on the option that has been selected. There are many select boxes on the page and my goal is just to get select boxes that have the "failure" css style.</p> <p>I think that I have got relatively close but I just can't get it to work for me. Relatively close means that I can get the css class displayed in a JavaScript alert box but when I try to use that text value in an if statement nothing happens. That code is below.</p> <p>Any pointers gratefully received.</p> <pre><code>$("select").each(function () { alert(this.options.item(this.options.selectedIndex).className); if (this.options.item(this.options.selectedIndex).className == 'frm_ddl_notOk') { alert('bunter?'); } }); </code></pre> <p>EDIT 20 hours later...</p> <p>I am an idiot. I mispelled the class that I was looking for. Should be "form_ddl_notOk". It is distinctly depressing how long it took me to notice. Especially after I used a prompt box so I could cut and paste the class name back into my code (and then didn't do it!).</p> <p>The imperfect code that I posted with my question worked when I used the correct class name.</p> <p>Here's some background to my question and responses to others questions and comments:</p> <p>When I find an element in "failure" I will look for a sibling element called "comments" and make it obligatory that "comments" be filled. I cannot base the selection on the option text I must base this on the class and/or bgcolor. The style is applied to the select element and the option element. I was using more general selectors just to try to figure stuff out.</p> <p>Thanks for your replies. Not sure whether I should mark any of them as the "answer". The universe would probably carry on without much amiss if this Q was deleted.</p>

    1. COYou want to check the select element or the selected option for the class? What does the HTML look like?

    2. COIs there something you plan to do with the `select` elements once you have identified them? Why can't you just use the class selector in jQuery? `$('select option.frm_ddl_notOk').each(...);`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
