jQueryで input, select, textarea を判定する

Posted at

やり方


$(":input").each(function() {
    var $this = $(this);
    if ($this.is("input")) {
        // <input> element.
    } else if ($this.is("select")) {
        // <select> element.
    } else if ($this.is("textarea")) {
        // <textarea> element.
    }
});

めも

textareaか???の判断をしたかったときに、 attr('type') で属性が取得できなかった。
よく考えれば、textareatypeなどない。どうやって判定するのかちょっと躓いたので、めもった。
