RESTful API for Encyclopaedia Metallum

This is an unofficial, third party RESTful API developed and maintained by me for retrieving metal bands data (band and artist bios, discographies, line-ups, etc) from Encyclopaedia Metallum.

Responses from the method calls are in JSONP format and the service is free, however providing an API key along with the requests is required. To use the API you should get a free API key from here first.

This service is not endorsed by or affiliated with Encyclopaedia Metallum.

You can check the documentation on this page and start using the API straight away.

Auto Resizing Textarea HTML5 WebComponent

Just finished my next experiment with HTML5 WebComponents. AcidJs.XTextarea is an advanced replacement of the classic <textarea /> HTML element, supporting custom events and auto resizing as-you-type. Check the extensive documentation in the distribution file (click the download button at the top of the demo page) or scroll this page to see the demos.

Usage

<acdisj-xtextarea></acdisj-xtextarea>
<acdisj-xtextarea placeholder="Type your message..." id="textarea-1" name="textarea-1" rows="5" cols="40"></acdisj-xtextarea>
<acdisj-xtextarea name="textarea-2" rows="10" cols="30" disabled></acdisj-xtextarea>
<acdisj-xtextarea name="textarea-5" autoresize="off" rows="5" cols="30"></acdisj-xtextarea>
<acdisj-xtextarea autofocus name="textarea-8" cols="60" rows="5"></acdisj-xtextarea>
<acdisj-xtextarea name="textarea-4" hidden></acdisj-xtextarea>

HTML Attributes of the Component

Apart from the form attributes like name, rows, cols, placeholder, spellcheck, autofocus, disabled and readonly etc. and the HTML standard attributes such is id and style AcidJs.XTextarea supports one custom property, allowing to turn the autoresizing off:

  • [autoresize="off"]

JavaScript API – Methods, Accessors and Events

The component supports all standard JavaScript methods querySelector, querySelectorAll, getElementById, etc. plus the following custom methods, accessors and events:

Methods

  • enable() – the method enables back a previously disabled textbox by using the disable() method, the enabled accessor or the disabled and readonly properties.
  • disable() – the method disables the queried textbox, so no user input is possible.
  • getValue() – the method returns the current value of the queried textbox, similar to the enabled accessor.
  • setValue(String|null) – the method sets new value to the queried textbox.

Accessors

  • enabled – gets or sets the enabled state of the textbox. Use Boolean value for the setter.
  • value – gets or sets value of the textbox. The setter requires a string or empty value.

Events

  • type – the event is triggered upon user input and returns an object, containing the current value of the textbox to which the event handler is bound to:
    {
        data: "Lorem ipsum dolor sit amet..."
    }
    /*
     * Bind to the "type" event of the textbox
     **/
     $("#my-textarea").on("type", function(e, data) {
         window.console.log("textbox event:", e.type, data);
     });

Corporate BS Generator HTML5 WebComponent

Nothing serious this time, just a small fun HTML5 WebComponent, inspired by BS Generator, stitching-up (bullshit) sentences out of random buzzwords:

Usage:

<acidjs-xbsgenerator></acidjs-xbsgenerator>

The component does not have it’s own methods, setters, getters or styles. Just use the tag wherever you want.

Enabling Placeholders in ContentEditable Elements with CSS

Recently I worked on an HTML5 app, utilizing contenteditable elements. According to the specs of the app, the empty editable elements were supposed to have placeholder texts and since the placeholder attribute is only supported by standard input boxes and textareas I was planning to use JavaScript to enable this functionality in contenteditable elements, but then I decided to try this small CSS trick with generated content and the attr(attribute) function, which actually worked:

The CSS:

[contenteditable]:empty::before
{
    content: attr(data-placeholder);
    font-style: italic;
    opacity: .75;
}

… And the Markup:

<div contenteditable data-placeholder="Add some text..."></div>

Adding Icons to the Option Elements of the Select Tag in Firefox. Quick and Dirty

Below is a quick and dirty solution for adding icons to the <option /> elements of the <select /> tag utilizing CSS generated content.

Disclaimer: According to the CSS specs, the <option /> element should not support generated content, and this solution works only in Firefox. Anyways, it may come handy sometime.

The Result:

The CSS:

.acidjs-cssw-select-icons option::before
{
    content: "";
    display: inline-block;

    margin: 2px 6px 2px 2px;
    width: 16px;
    height: 16px;
    background: url("path/to/the/icon.png") no-repeat center;
}
