jQuery Placeholder

これはなに？

HTML5のplaceholder属性のようにガイドテキストを薄く表示する為のjQueryプラグイン。

使い方

HTML

<input type="text" value="" data-placeholder="Input your name" class="mytext" />

data-placeholder属性でデフォルト値を設定

CSS

.jquery-placeholder {
	color:#cccccc;
}

ガイドテキスト表示時のスタイルをクラスで記述
初期設定ではクラス名は"jquery-placeholder"になっています

JavaScript

$("input.mytext").placeholder();

引数でオプションを渡すことも出来ます。

$("input.mytext").placeholder({
	defaultClass : "myclass"
});

引数で文字列を渡すと、defaultClassに渡されます。 上と下のコードは同義です。

$("input.mytext").placeholder( "myclass" );

オプション

defaultClass (string) : ガイドテキスト表示時にあてるクラス名
resetOnSubmit (boolean) : 送信時に値をクリアするかどうかのbool値
