JavaScript における文字コードと「文字数」の数え方 | blog.jxck.io
Intro textarea などに入力された文字数を、 JS で数えたい場合がある。 ここで .length を数えるだけではダメな理由は、文字コードや JS の内部表現の話を理解する必要がある。 多言語や絵文字対応なども踏まえた上で、どう処理するべきなのか。 それ自体は枯れた話題ではあるが、近年 ECMAScript に追加された機能などを交えて解説する。 なお、文字コードの仕組みを詳解すること自体が目的では無いため、 BOM, UCS-2, Endian, 歴史的経緯など、この手の話題につき物な話の一部は省くこととする。 1 文字とは何か Unicode は全ての文字に ID を振ることを目的としている。 例えば 😭 (loudly crying face) なら 0x1F62D だ。 1 つの文字に 1 つの ID が割り当てられているのだから、文字の数を数える場合は、この ID

文字列を省略して「…」を付与する方法 – CSS/jQuery | DevelopersIO
通常、設計・デザインの段階であらかじめ表示する文字数の上限を決めておき、PHPやRuby、Javaなどサーバサイドで表示する文字列を加工することが多いかと思います。 しかし、この方法だと動的に変化する領域を基準に表示する文字数を制限する場合や、文字サイズや表示領域のサイズに合わせて上限を算出する場合に限界があります。 そこで、クライアントサイドで表示領域から文字列がはみ出す場合、文字列を省略して省略記号「…」をつける方法を紹介してみたいと思います。 実現方法として以下の2つの方法があります。 text-overflowプロパティを使う jQueryで表示領域の幅・高さに合わせて文字列を加工する text-overflowプロパティを使う text-overflowプロパティを用いると、文字列が表示領域からはみ出してしまった場合、はみ出した文字列を省略記号「…」で省略することができます。 尚
