Retrieving optgroup label for selected option in a drop down list with Mootools

11/08/2011

Just a quick tip for getting the selected option optgroup label using Mootools:

The HTML:

<select id="transport">
    <optgroup label="Cars">
        <option>Ford</option>
        <option>BMW</option>
        <option>Mercedes</option>
    </optgroup>
    <optgroup label="Motorbikes">
        <option>Honda</option>
        <option>Yamaha</option>
        <option>BMW</option>
    </optgroup>
</select>

Mootools JavaScript:

// get optgroup label of selected option on change
document.id("transport").addEvent("change",function(){
    var optGroup=this.getSelected().getParent("optgroup").get("label");
    // do something with the label
    alert(optGroup);
})

I imagined that it would be implemented on websites by web developers like myself so this script would just become “part” of the integration.

Mootools Splash Screen

2/02/2010

Every now and then you get a client that absolutely insists on having a “splash screen“. However hard you try to convince them that it is not good for SEO (search engines like content and links) or for visitors (after all, you are wasting their time), they refuse to see it your way and insist on having it.

I had one of them this week and, rather than spending the time and energy on trying to persuade the client, I decided to have a go at making one with my favorite javascript Library – Mootools.
